SUBJECT: RESPIRATORY PROTECTION REFERENCE MANUAL
Attached is a revised draft of Respiratory Protection Program Guidelines.
The revisions include the various minor suggestions for improvements, plus changes in the physical capability section in response to input from Corporate Medical. While the basic approach to determining physical capability remains the same, the role of the voluntary physical examination has been deemphasized. This change was made to protect the confidential physician/patient relationship which is fundamental to the success of the voluntary physical examination program. Dr. Simpson has agreed with this revised approach.
The section on facial hair remains (for the moment) essentially as proposed, with the second (less stringent) alternative still included. As you are aware, it has been proposed that the second alternative (top of page 7) be deleted. This amounts to "biting the bullet", and adopting the "no established facial hair" position. This position apparently is supported by Pipe Line, Marketing Distribution, R&D, and E&P.: Manufac turing and IR are requested to give serious consideration to this position.
Comments should be returned by February 12. We will discuss this item again at the February 24 SX meeting.

c. Provisions for contractor personnel as appropriate.
d. Provisions for casual visitors, allowing for immediate exit from the affected area as an
alternative (i.e., casual visitors are defined as
not subject to the use of respirators).
Alternatively, locations that use respirators may develop the following approach into a procedure.
a. Instruct employees regarding the effect of facial hair in defeating the protection provided by
respirators. b. Encourage employees to alter established facial hair
such that there is no Interference with the
respirator seal. c. Require all employees who do not alter facial hair
to wear only air-supplied breathing apparatus with positive pressure (i.e., pressure demand mode).
For some locations, alternative 2 may be a satisfactory long-term approach. For others, alternative 2 may be an effective interim approach (i.e., for several years), particularly if coupled with quantitative fit testing which effectively demonstrates the defeat of respiratory protection by facial hair.
4. Corrective eye^alws
Eyeglasses also cause leakage where the respirator seal passes over the temple bar. For this reason, piano safety glasses should always be removed when using a full-face piece respirator.
Persons requiring corrective eye wear to safely perform work
must, of course, wear such eye wear when using a respirator.
For tasks where the respiratory hazard does not affect the
eyes, a half-face piece respirator (which does not interfere
with standard corrective eyewear) may be used. Alternatively,
or where the respiratory hazards does
affect the eyes, a
supplied air respirator should be used in pressure demand
mode.
Locations are encouraged to provide specially framed corrective lenses, which fit inside the respirator, for those employees who prefer them.
Wearing of contact lenses under respirators is not permitted.
The references below provide further information for identifying health and physical conditions which can affect an individual's ability to wear respirators.

RESPIRATOR SELECTION
V-l (5/81)
To assist in respirator selection, this section includes:
1. Chapter 6 of NIOSH's "A Guide To Industrial Respiratory Protection". This chapter introduces basic considerations for establishing respirator use. In addition, several examples of respirator selec tion using the OSHA/NIOSH Respirator Decision Logic are explained. *>
2. Joint OSHA/NIOSH Respirator Decision Logic, Appendix F of NIOSH's "A Guide to Industrial Respiratory Protection". The OSHA/NIOSH Respirator Decision Logic is a step-by-step process of selecting respirators. It was developed as a mechanism for establishing respirator requirements for individual OSHA health standards. It sets a number of conventions including conservative protection factors. Compliance is not required by law.
3. Several tables from ANSI Z88.2 (1980). The Table of Respirator Protection Factors, in combination with the OSHA/NIOSH Respirator Decision Logic, can guide respirator selection. (See Appendix C of this manual.)
4. Several references related to respirator cartridge efficiency.
The following references are not Included in this guide, but can also provide additional information. Each guide user may want to have the following routinely-used references.
1. NIOSH Certified Equipment List
This manual lists those respirators tested and certified by NIOSH. The latest issue is dated June 1, 1980. The manual is updated approximately annually. The next issue is due in the last quarter of 1981. Contact the Testing and Certifica
tion Branch (304/599-7331) for information on certified,, products that are not listed in this publication. (The1 publication does not list any devices formerly approved by
the Bureau of Mines.),
2. OSHA Standards 1910 (Asbestos, 1910; Vinyl Chloride, 1910; Lead 1910)
These specific health standards define respirator selection requirements.
3. The AIHA, "Respiratory Protection, A Manual and Guideline"
4. OSHA/NIOSH "Pocket Guide to Chemical Hazards", NIOSH Pub. No. 78-210
This reference recommends respirator types for substances found in 29 CFR 1910.1000 Tables Z-l, Z-2, and Z-3 as of 1977. In addition, it quotes IDLH levels for these same substances.

RESPIRATOR SELECTION
OSHA STANDARDS
OSH A 1010.13-4 states that respirators shall he selected on the basis of the hazards to which workers
are exposed and that ANSI ZK8.2-1969 shall be used for guidance in their selection. OSHA also requires that approved or accepted respirators be used when available. For certain respiratory hazards, specific instructions about respirator use are given in other OSHA regulations. The trend seems to be toward regulations that specify the conditions of respirator use for each task. OSHA 1910.134 is then consulted for general instructions. Regardless of the regulations, respirators must be selected with the en vironment in which they will be used in mind. To do so requires certain basic information, so one should always ask the following questions before selecting a respirator.
1. What is the estimated contaminant concentra tion where the respirator will be used?
2. What is the permissible exposure limit to the contaminant?
3. Is the contaminant a gas. vapor, mist, dust, or fume?
4. Could the contaminant concentration be term ed immediately hazardous to life or health?
o. If the contaminant is flammable, does the es timated concentration approach the lower explosive limit?
6. Does the contaminant have adequate warning properties?
7. Will the contaminant irritate the eyes ar the es timated concentration?
8. If the contaminant is a gas or vapor, is there an available sorbent that traps it efficiently?
9. Can the contaminant be absorbed through the skin as a vapor or liquid? If so, will it cause serious injury?
The answers to these questions can provide enough information for choosing a respirator for routine use. There is nothing strange or unique about these questions. They represent the factors that a good industrial hygiene program would incor porate for respirator selection or any other type of control and form the basis for the Respirator Deci-; sion Litgic (incorporated verbatim as Appendix F)
used in ihp -Joint NIOSH and OSHA Standards
Completion Program.

the above questions in an orderly sequence Hv
following this logic, you will be able to choose a
respirator (hat is satisfactory fur the situaiion ol
hand and be assured that you have not mcrlunkcii
any important factor.
The Decision Ligic is being used (in I!I7M in
development of detailed work practices for the
material listed in 29CFR Part 1910.1000. Tables Z-1.
2. and 3. It will be useful to you in developing your
own respirator program until standards are listed for
the particular materials in which you are interested.
Before procerling to examples o| how to use the I Irci
sion Digie. we would like to |Htinl out lour criteria ol
particular interest.
When respirators are used for protection against
gases and vapor, it is commonly recoin mended
that cartridges be changed when the wearer smells
the vapor. This indicates that there must be some
smell or irritation tonlert the wearer. Section IV H
of the Decision Logic 9tates that a sulistBncc
should be considered to have warning pru|ierties if
the odor or irritation threshold is not more than
three times the exposure limit, and there is no ceil
ing limit. Consideration is given to whether un
detected exposure in this concentration range
could cause serious or irreversible health effecis. 11
not. the substance is considered to have adequate
warning properties.'
Section IV C states that where there is supixirting
evidence of vapor breakthrough in less than three
minutes at concentrations immediately dnngerou>
to life or health or below, a cartridge or canister
sorbent air purifying device should not be allowed
for any use. The principal sources of information
on sorbent efficiencies are Lawrence Livermore
Laboratory and 30 CFR-11 on certain specilic
materials on which cartridge tests are run. Users
should be alert to any future information on sor
bent efficiency, as it will definitely affect choice ol
air purifying respirators.

RESPIRATOR PROTECTION FACTORS
Va-2 (5/81)
so ihe respirator mu*i be pmperlv mainimncd Other limitations nf various'types of respirators dis cussed in Chapter Eight must also be considered in applying protection factors.
Definition
EXAMPLES OF RF.SPIRAfOR SELECTION
The respirator protection factor indicates how much protection a respirator provides. It is the ratio of the contaminant concentrations outside and in side the respirator. Determination of the protection factor requires quantitalive.performance tests of the respirator worn in a test atmosphere during exercise simulating motions made by workers, or worn by workers carrying out tasks in contaminated work areas (see Chapter fit.
Assignment
Much research has been done recently on assign ing protection factors to various types of respirators. Table 6-1, reproduced verbatim from the LASL protection factor document, lists assigned respirator protection factors resulting from this research. When using Table 6-1. pay strict attention to its footnotes as they are essential in interpreting the table and assist in application of protection factors. The protection factors listed in the Decision Logic are taken from Table 6-1.
Application
To apply an assigned protection factor for a par ticular type of respirator, one must know both the actual contaminant concentration in the work area and the established time-weighted average concen tration. Multiplying the time-weighted average con centration by the respirator protection factor gives the maximum concentration of the contaminant against which the particular type of respirator may he used. If the actual concentration is less than the calculated maximum use concentration, the respirator may be used.
In describing use of protection factors in respirator selection, it is assumed that a complete respirator program is in force. A protection factor is not applicable if the wearer cannot satisfactorily seal the respirator to his face or head. Anything such as facial hair or spectacles that prevents satisfactory sealing of a respirator nullifies application of a respirator protection factor. A protection factor can be used only ,f the respirator is in good operating condition.
The following are hypothetical hut typical ex
amples of the respirator selection process. They
should not be used as cookbook models, hut as
guides to the rationale for selecting particular
respirators, and. equally important. to the industrinl
hygiene aspects of the hazards. In these examples,
we assume that regular use nf respirators is permissi
ble.
1. A muller operator in a foundry rnmplnins of
dust in the air. and the superintendent supplies him
a single-use. disposable respirator. The steward tells
the superintendent that this is a violation of the
OSHA Regulations as the particular respirator does
not have NlOSH and MESA approval. Who is right, and what should he done?
Answer: Nothing bans the sale or use of unapproved
devices in areas where respirators are not required.
Before deciding about use of this respirator, we need
information about the dust concentration in the air.
Samples were taken in the muller's breathing zone,
and the dust concentration was found to lie 5
mg/m'*. The amount or crystalline silica ((piiirt/t in
the dust was
The permissible quart/ dust ex
posure limit in such conditions is 1.6 mg/ni"1 .
Now refer to Section II of the Respirator Decision
l>ogic. Appendix F. Because the material is a par
ticulate. statements 2. 4. and 6 are not pertinent. As
to the other statements: 3) Silica is not known to be
an eye irritant, 51 the 1DLH concentration is far
above the 5-mg/mn dust level found in this ruse, and
7) to date, there is no evidence of injury from silica
through skin absorption. As the material is a par
ticulate, we can proceed to Section III B. the specific
decision logic chart for respiratory protection against
particulates. The restrictions under Routine Use do
not apply, so we can proceed to Appendix 1. Section
A. "Protection Factors for Particulate Filter
Respirators." As the dust concentration is less than
five limes the permissible limit, we can choose any
respirator from this list. A single-use respirator with
a protection factor of 5 or a half-mask respirator with
a protection factor of 10 probably would he chosen.
2. A woman doing silk screening without any local
exhaust ventilation complained of headaches and
nausea from the vapors and fumes. She was given a
dust respirator customarily used by a sandblaster's
helper. (Obviously a dust respirator for use against

1 The overall protection afforded by a given respirator design (and mode of operation) may be defined in terms of its protection factor <PF). The PF is a measure of the degree of protection afforded by a respirator, defined as the ratio of the concentration of contaminant in the ambient atmosphere to that inside the enclosure (usually inside the facepiece) under condi tions of use. Respirators should be selected so that the concentration inhaled by the wearer will not exceed the appropriate limit. The recommended respirator PF's are selection and use guides, and should only be used when the employer has established a minimal acceptable respirator program as defined in Section 3 of the ANSI Z88.2-I969 Standard.
,ln addition to facepieces, this includes any type of enclosure or covering of the wearer's breathing zone, such as supptied-air hoods helmets, or suits.
1 Includes dusts, mists, and fumes only. Does not apply when gases or vapors are absorbed on particulates and may be volatilized or for particulates volatile at room temperature. Example: Coke oven emissions.
4Any single-use dust respirator (with or without valve) not specifically tested against a specified contaminant.
* Single-use dust respirators have been tested against asbestos and cotton dust and could be assigned a PF of 10 for these particulates.
*Dust filter refers to a dust respirator approved by the silica dust test, and includes all types of media, that is. both nondegradablc mechanical type media and degradable resin-impreg nated wool felt or combination wool-synthetic felt media.
1 Fume filter refers to a fume respirator approved by the lead fume test. All types of media ate
included.
T * High-efficiency filter refers to a high-efficiency particulate respirator. The filter must be at
least 99.97% efficient against 0.3 pm OOP to be approved.
1`
*To be assigned, based on dust or fume filter efficiency for specific contaminant.
,#For gases and vapors, a PF should only be assigned when published test data indicate the cartridge or canister has adequate sorbent efficiency and service life for a specific gas or vapor. In addition, the PF should not be applied in gas or vapor concentrations that arc: 1) immediately dangerous to life. 2) above the lower explosive limit, and 3) cause eye irritation when using a half-mask.
(IA positive pressure supplied-air respirator equipped with a half-mask facepiece may not be as stable on the face as a full facepiece. Therefore, the PF recommended is half that for a similar device equipped with a full facepiece.
i
11A positive pressure tupplied-air respirator equipped with a full facepiece' provides eye protection but is not approved for use . in atmospheres immediately dangerous to life. It is recognized that the facepiece leakage, when a positive pressure is maintained, should be (he same as an SCBA operated in the positive pressure mode. However, to emphasize that it basically is not for emergency use. the P F is limited to 2,000.

can be used. If Ibis is impossible, the only recourse is to provide the helper the same protection as the sandbla-tcr. Remember, the air supply system must meet the requirements for Grade D or better compressed air.
The point illustrated in this example is that it is not enough to abide only by the requirements of 29 CFR Part 1910.134 which is concerned with general use of respirators. There are other requirements within the OSHA regulations which may also affect respirator selection and use.
I sc of the Decision Logic was not mentioned in
this example. The regulations requiring use of a supplied air hood were made before assembly of the Decision I>ogic. You will note that the Decision lairic Protection Factor Table lists a PF or 2tH(0 for the supplied air hood. Considering the unknown coneent rat ion of silica dust to which t he sandblaster can lie oxposrd. the protection required is consistent with the Decision l/>gic.
4. A man assigned to clean a large degreaser must occasionally go into the degreaser pit. He complains that the odor of trichloroethylene (trichlorl is so strong that it comes through his respirator cartridges after only a short time. Should he be assigned another type of respirator?
Answer: The fact that the worker complains about the short lifetime of the sorbent cartridges warns that the trichlor concentrations may be high. This brings up the dual hazards of toxicity and ox ygen deficiency. Degreaser pits are places where vapors may collect and, unless ventilated, actually reduce the oxygen below safe levels. Unless the pit is ventilated to prevent oxygen depletion, a positive pressure SCBA must be used. If the pit is ventilated, it will not be necessary to wear a respirator if tests show that the trichlor concentration is below the ex posure limit and that the oxygen has nnt been depleted.
Again, the Decision Logic Section til A shows that for entry and escape from unknown concentrations the only type of device that can be used is positive pressure self-contained breathing apparatus.
5. A flagman for an aerial crop duster using Phosdrin dust is supplied a single-use disposable dust respirator. Is this adequate?
Answer: Several points listed in the Decision Logic flow chart are pertinent here. Pesticides such as Phosdrin are noted for their ability to kill by absorbtion through the skin. The single-use respirator certainly does not provide complete skin protection. In such cases, protective clothing is as important ns a proper respirator.
The pesticide is mixed with the dust: however, some of it may vaporize from dust. This is one reason
Va-4
(5/81 )
why the only respirators approved for pesticide W'-c
have organic charcoal in back of the dust filter.
The Phosdrin concentration to which thp flagman
is exposed is not stated. Before! a respirator can he
assigned, we must know the approximate concent ra
tion expected. If the concentration cannot ! es
timated. the flagman will have to be provided with a
self-contained breathing apparatus.
6. Hydrocyanic acid is used in a fumigation
chamber. By state regulation, a full-face respirator
or gas mask with a hydrocyanic acid canister is re
quired. Is such protection satisfactory?
Answer: To decide whether the respirator is ade
quate. one must have some knowledge of the toxicity
and potential concentration of the hydrocyanic acid.
The TI.V for hydrocyanic acid is listed as 10 ppm.
with a warning that skin absorption is a problem.
Regardless of the respiratory protection provider!,
there must be some protection for the skin in such an
atmosphere.
A review of the toxicity of hydrocyanic acid will
showth8t a concentration of 270 ppm is immediately
fatal and concentrations of 110 ppm ere fata! within
half an hour. Concentrations of hydrocyanic acid in
fumigation chambers usually exceed
<10.000
ppml. The full-face gas mask is accorded a protec
tion factor of only 50 in Table 6-1, Therefore, it
would not he useful in concentrations above 500
ppm. Such a mask would not be satisfactory in this
case. The Decision Logic offers a quicker solution.
Section HI A notes that when the contaminant con
centration exceeds that immediately dangerous to
life or health, only positive pressure self-contained
breathing apparatus is acceptable respiratory
protection.
7. A salvage company is to demolish a large open-
framework steel structure built in 1910 in a southern
eitv. The job will require extensive use of cutting
torches. Will respirators be required, and if so. of
what type?
Answer: Respirators definitely must be used. As
the structure was built in 1910. it undoubtedly has
many coats of lead-base paint, which when heated
by the cutting torches will create a severe airborne
lead problem. Therefore a respirator approved for
protection against metal fumes can he used.
Whether this will be a quarter- or half-mask or full-
facepiece respirator can be determined only after air
samples are taken in the wearers' breathing zones.
Because this is an outdoor operation, the concen
trations will vary widely. However, similar
operations have shown that concentrations of 2
mg/m1 are not unusual. Considering the low protec
tion factors for air-purifying respirators, the high
temperatures in this climate, and the added heal

NOTE 4) COVERS GAS MASKS (CANISTER RESPIRATORS) AND 30 CFR 11,150 (NOTE
7) COVERS CHQLICAL CARTRIDGE RESPIRATORS. THUS THESE APPROVALS ARE ONLY
FOR THOSE ORGANIC VAPORS WITH ADEQUATE WARNING PROPERTIES AND NOT.ALL
ORGANIC VAPORS.
j
WARNING PROPERTIES RELYING UPON HUMAN SENSES ARE NOT FOOLPROOF,'
HOWEVER, THEY PR0V1QE SOKE INDICATION TO THE EMPLOYEE OF P0S51BLE SORBENT EXHAUSTION OR OF POOR FACEPIECE FIT OR OTHER RESPIRATOR MALFUNCTION, WARNING PROPERTIES INCLUDE ODOR, EYE IRRITATION, AND RESPIRATORY IRRITATION.
ADEQUATE WARNING PROPERTIES CAN BE ASSUMED WHEN THE SUBSTANCE ODOR, TASTE, OR IRRITATION EFFECTS ARE DETECTABLE AND PERSISTENT AT CONCENTRATIONS *AT* OR -BELOW* THE PERMISSIBLE EXPOSURE LIMIT. ,
IF THE ODOR OR IRRITATION THRESHOLD OF A SUBSTANCE IS MANY TIMES GREATER THAN THE PERMISSIBLE EXPOSURE LIMIT, THIS SUBSTANCE SHOULD BE CONSIDERED TO HAVE POOR WARNING PROPERTIES. IF THE SUBSTANCE ODOR OR IRRITATION THRESHOLD IS SOMEWHAT ABOVE THE PEW1SSIBLE EXPOSURE LIMIT (NOT IN EXCESS OF THREE TIKES THE LIMIT) AND THERE IS NO CEILING LIMIT, CONSIDERATION IS G!YEN AS TO WHETHER OR NOT UNDETECTED EXPOSURE IN TN1S CONCENTRATION RANGE COULD CAUSE SERIOUS OR IRREVERSIBLE HEALTH EFFECTS. IF NOT, THE SUBSTANCE IS CONSIDERED TO HAVE ADEQUATE WARNING PROPERTIES.

IT IS EXPECTED THAT EKVIR01HENTAL CONCENTRATIONS WILL VARY CONSIDERABLY AND. THEREFORE, WARNING OF A RESPIRATOR FAILURE WOULD SOON BE PERCEIVED AT CONTAIHINAKT CONCENTRATIONS SCHEWHAT ABOVE THE PERMISSIBLE EXPOSURE UNIT.
IV. C. SORBENT EFFICIENCIES
WHERE SUPPORTING EVIOENCE EXISTS ON IMMEDIATE (LESS THAN THREE MINUTES) BREAKTHROUGH TINE AT THE IOLH CONCENTRATION AND BELOW FOR A CARTRIDGE OR CANISTER SORBENT, AIR-PURIFYING OEVICES SHALL NOT BE ALLOWED FOR ANY USE, ESCAPE OR OTHEW1SE.
IV. D. EYE IRRITATION
FOR ROUTINE WORK OPERATIONS, ANY PERCEPTIBLE EYE IRRITATION IS CONSIDERED UNACCEPTABLE, THEREFORE. ONLY FULL FACEPIECE RESPIRATORS ARE PERMISSIBLE IN CONTAMINATION CONCENTRATIONS WHICH PRODUCE EYE IRRITATION NOTE THAT 30 CFR 11.90(B) (NOTE 6) SPECIFIES THAT EYE PROTECTION MAY BE REQUIRED IN CERTAIN CONCENTRATIONS OF ACID GASES AND ORGANIC VAPORS. FOR ESCAPE. SWE EVE IRRITATION IS PEWISSIBLE IF IT IS DETERMINED THAT SUCH IRRITATION WOULD NOT INHIBIT ESCAPE AND SUCH IRRITATION IS REVERSIBLE.
WHERE QUANTITATIVE EYE IRRITATION DATA CANNOT BE FOUND IN LITERATURE REFERENCES. AND THEORETICAL CONSIDERATIONS INDICATE THE SUBSTANCE SKOULO NOT BE AN EYE IRRIYANT, HALF FACEPIECE RESPIRATORS ARE ALLOWEO.
IY. IOLH
THE DEFINITION OF IOLH PROVIDED IN 30 CFR 11.3(T) IS AS FOLLOWS:
"IMMEDIATIEY DANGEROUS TO LIFE OR HEALTH* MEANS CONDITIONS THAT POSE AN IMMEDIATE THREAT TO LIFE OR HEALTH OR CONDITIONS THAT POSE AN IMMEDIATE THREAT OF SEVERE EXPOSURE TO CONTAMINANTS. SUCH AS RADIOACTIVE MATERIALS, WHICH ARE LIKELY TO HAVE ADVERSE CUMULATIVE OR DELAYED EFFECTS ON HEALTH.
THE PURPOSE OF ESTABLISHING AH IOLH EXPOSURE CONCENTRATION IS TO INSURE THAT THE WORKER CAN ESCAPE WITHOUT INJURY OR IRREVERSIBLE HEALTH EFFECTS FROM AN IDLH CONCENTRATION IN THE EVENT OF FAILURE OF THE RESPIRATORY PROTECTIVE EQUIPMENT. THE IDLH IS CONSIDERED A MAXIMUM CONCENTRATION ABOVE WHICH ONLY HIGHLY RELIABLE BREATHING APPARATUS PROVIDING MAXIMUM WORKER PROTECTION IS PEWITTED. SINCE IOLH VALUES ARE CONSERVATIVELY SET, ANY APPROVED RESPIRATOR MAY BE USED UP TO ITS MAXIMUM USE CONCENTRATION BELOW THE IOLH.
IN ESTABLISHING AN IDLH EXPOSURE CONCENTRATION THE FOLLOWING FACTORS ARE CONSIDERED:
1. ESCAPE WITHOUT LOSS OF LIFE OR IRREVERSIBLE HEALTH . EFFECTS. THIRTY MINUTES IS CONSIDERED THE MAX [MW REMISSIBLE EXPOSURE TIME FOR ESCAPE.
2. SEVERE EYE OR RESPIRATORY IRRITATION OR OTHER REACTIONS WHICH WOULD INHIBIT ESCAPE WITHOUT INJURY.
IOLH SHOULO BE DETERMINED FRCK THE FOLLOWING SOURCES:
1. SPECIFIC IDLH PROVIDED IN THE LITERATURE SUCH AS THE AIHA HYGIENIC GUIDES.
2. HJHAH EXPOSURE DATA.
I j
HUT 082647 ANA-06027
3. ACUTE ANIMAL EXPOSURE DATA.
i >.
4. WHIRL SUCH DATA ARE LACKING TOXICOLOGICAL DATA FROM '
ANALOGOUS SUBSTANCES. AND CHRONIC ANIMAL EXPOSURE DATA MAX BE CONSIDERED.
THE FOLLOWING GUIDELINES SHOULD BE USED TO INTERPRET TOXICOLOGICAL DATA REPORTED IN THE LITERATURE FOR ANIMAL SPECIES:
1. WHERE ACUTE EXPOSURE ANIMAL DATA ARE AVAILABLE (30 MINUTES TO 4-HOUR EXPOSURES). THE LOWEST EXPOSURE CONCENTRATION CAUSING DEATH OR IRREVERSIBLE HEALTH EFFECTS IN ANT SPECIES IS DETEWINED TO BE THE IDLH CONCENTRATION.
2. WHERE ONLY CHRONIC EXPOSURE DATA ARE AVAILABLE AND THESE
DATA DO NOT REVEAL ANY EXPOSURE CONCENTRATION WHICH WOULD
RESULT IN IRREVERSIBLE HEALTH EFFECTS. THEN THESE DATA
HAVE NO RaEVANCE AND SHOULD NOT BE USED IN DETERMINING
THE IDLH CONCENTRATION.
^
WHERE THERE IS EVIDENCE OF AN IOLH CONCENTRATION ABOVE THAT ALLOWED ON THE BASIS OF A PROTECTION FACTOR. RESPIRATORS SHOULO BE SELECTED ON THE BASIS OF THE PROTECTION FACTOR AFFORDED BY EACH DEVICE WITHIN THE LIMITATIONS OF THE DEVICE.
IV, E. LOWER FLAMMABLE L1HIT AHD FIREFI6HTINC
CONTAINJKANT CONCENTRATIONS IN EXCESS OF THE LFL ARE CONSIDERED TO BE IMMEDIATELY DANGEROUS TO LIFE OR HEALTH. AT OR ABOVE THE LFL. THE USE OF RESPIRATORS IS LIMITED TO THOSE DEVICES WHICH PROVIDE THE KAXIKltM PROTECTION, I.E.. POSITIVE-PRESSURE SCBA. AND COMBINATION POSITIVEPRESSURE SUPPLIED-AIR RESPIRATOR WITH POSITIVE PRESSURE SCBA.
FIREFIGHTING IS DEFINED BY ANSI Z88.S-1971 AS BEING IMMEDIATELY DANGEROUS TO LIFE. FOR FIREFIGHTING, THE ONLY DEVICE PROVIDING ADEQUATE PROTECTION IS THE POSITIVE PRESSURE SELF-CONTAINED BREATHING APPARATUS.
IV. 6 PROTECTION FACTORS
PROTECTION FACTORS ARE A MEASURE OF THE OVERALL EFFECTIVENESS OF, A RESPIRATOR. FILTERING EFFICIENCY IS A PART OF THE PROTECTION FACTOR AND BECOMES A SIGNIFICANT CONSIDERATION FOR LESS EFFICIENT AIR PURIFYING RESPIRATORS.
THE PROTECTION FACTORS USED IK THE PREPARATION OF THE STANDARDS ARE BASED ON QUANTITATIVE FIT TESTS PERFORMED AT LOS ALAMOS AND RSEWHERE, AND IN SOME INSTANCES OK PROFESSIONAL JUDGMENT. IN APPENDIX I. THE PROTECTION FACTORS FOR EACH CLASS OF RESPIRATORS LISTED IN THE CHECKLISTS ARE SHOWN. THE ENTRIES IK EACH LIST ARE FOR AN ENTIRE CUSS OF RESPIRATORS, AND ARE ASSIGNED THE PROTECTION FACTOR OF THE LOWEST PERFORMING 0EV1CE WITHIN EACH CUSS.
IV. H. VARIATIONS WITH 30 CFR U
1. THE TYPE A SUPPLIED-AIR RESPIRATOR IS ALLOWED IN 30 CFR11 FOR USE IN IMKEOIATar DANGEROUS TO LIFE AND HEALTH ATMOSPHERES. HOWEVER. AIR SUPPLY REQUIRBMEKTS OF 50 L/MIN. IS INSUFFICIENT TO MAINTAIN A POSITIVE PRESSURE IN THE FACEPIECE UHOER ALL WORKING CONDITIONS. THEREFORE, THIS DEVICE SHOULD HAVE THE SAME PROTECTION FACTOR AS APPLIED TO OTHER AIR-PURIFYING AHD ATMOSPHERE SUPPLYING RESPIRATORS HAVING A NEGATIVE PRESSURE IN THE FACEPIECE (SEE APPENDIX I), 30 CFR

11 HILL REQUIRE A REVISION TO ELIMINATE APPROVAL OF TYPE A FOR IOLH ATMOSPHERES.
2. AN AMENDMENT TO 30 CFR 11 IS BEING PROCESSED WHICH WILL DELETE USE OF GAS MASKS FOR ENTRY AND USE IN ISLH ATMOSPHERES. THEREFORE* IN THIS DECISION LOGIC GAS MASK ARE NOT ALLOWED IN CONCENTRATIONS GREATER THAN THE ISLH OR ENTRY AND ESCAPE FRW UNKNOWN CONCENTRATIONS.
3. IN THE SAME AHENCHENT DESCRIBED ABOVE. MAXIMUM USE CONCENTRATIONS (MUC) FOR GAS MASKS ARE BEINGING DELETED. THIS DECISION LOGIC IS CONSISTENT WITH THIS AMENDMENT. HOWEVER. CANISTERS APPROVED PRIOR TO THIS AMENDMENT WILL HAVE THE MUC SPECIFIED ON THE LABEL WHICH WILL BE INCONSISTENT WITH THE SUBSTANCE STANDARDS FOR MOST SUBSTANCES.
A. 30 CFR 11 DOES NOT CONTAIN PROTECTION FACTOR REQUIREMENTS. PROTECTION FACTORS ARE USED IN THE DECISION LOGIC. AN AMENDMENT TO 30 CFR 11 IS PLANNED TO INCLUDE PROTECTION FACTOR REQUIREMENTS FOR OFM RESPIRATORS. FUTURE AMENDMENTS ARE COITEMPLATED FOR OTHER TYPES OF RESPIRATORS.
S. 30 CFR 11 DOES NOT PEWIT THE USE AN ESCAPE GAS MASK AGAINST AC10 GASES OR ORGANIC VAPORS WITH POOR WARNING PROPERTIES. A CHANGE TO 30 CFR II IS NECESSARY TO PERMIT THE USE OF AN ESCAPE GAS MASK AGAINST SUBSTANCES WITH POOR WARNING PROPERTIES.

CLASSIFICATION OF RESPIRATORS AWO THEIR LIMITATIONS AIR PURIFYING RESPIRATORS
Mode Of Operation
LimiLations
Ambient air, prior to being
Inhaled, Is passed through a filter, cartridge, or canister which removes particles, vapors, gases, or a combination of these contaminants. Breathing action of the wearer operates the non powered type. Powered type contains
a blower, stationary or carried by
wearer, which passes ambient air through an air-purifying component and then supplies purified air to the respiratory-inlet covering. Konpowered type is equipped with a facepiece or mouthpiece, and nose clamp. Powered type is equipped with a facepiece, helmet, hood, or suit.
Air-purifying respirators do not protect against oxygen-deficient atmospheres nor against skin irritations by airborne contaminants, or sorption through the skin.
The maximum contaminant concentration against which an air-purifying respirator will protect is determined by the design efficiency and capacity of the cartridge, canister or filter, and the facepiece-lo-face seal on the user. For gases and vapors, the maximum concentration for which the air-puritying element is designed is specified by the manufacturer, or is listed on labels of cartridges and canisters. The type of facepiece used may be limited by its protection factor.
Konpowered air-purifying respirators will not provide the maximum design protection specified unless the facepiece or mouthpiece/nose clamp is carefully fitted to the wearer's face to prevent inward leakage. The time period over which protection is provided is dependent on canister, cartridge or filter type, concentration of contaminant, humidity levels in the ambient atmosphere, and the wearer's respiratory rate.

The proper type of canister, cartridge, or filter must be selected for the particular atmosphere and conditions. Nonpowered air-purifying respirators may cause discomfort due to a noticeable resistance to inhalation. This problem is minimized in powered respirators. Respirator facepieces present special problems to individuals required to wear prescription lenses. These devices do have the advantage of being small, light, and simple in tperalion.
Use of air-purifying respirators in atmospheres immediately dangerous to life or health is limited to specific devices under specified conditions.
(Copied from the latest update of the ANSI 738.? (193G) Standard ''Respiratory Piotection Prac t ices ''. )
Ve-1 (5/(11 )
There ere three types of air purifying respirators: (1) particulate-removing respirators (?) vapor end gas-removing
respirators and (3) combinations of 1 and 2.
ANA-06040
Mode of Operation 1) Particulate-Removing Respirators
Equipped with fllter(s) to remove a tingle type of particulate matter (e.g., dust) or a combination of two or more types of particulate matter (e.g., dust and fume) from air. filter may be a singleuse type or reusable type.
2) Vapor-and Gas-Removing Respirators
Equipped with a cartridge(s) or canister(s) to remove a single vapor or gas (e.g., chlorine gas), a single class of vapors I or gases (e.g., organic vapors), or a 5 combination of two or more classes of vapors or gases (e.g., organic vapors a and acidic gases) from air.
3) Combination Particuiate-Vapor-and Gas-Removing Respirators
Equipped with cartridge(s) or canister(s) to remove particulate matter, vapors and gases from air. The filter may be a permanent part or a replaceable part of a cartridge or canister.
limitations Particulate-Removing Respirators
Protection against nonvolatile particulates only. No protection against gases and vapors.
Not for use in atmospheres immediately dangerous to life or health unless a powered-type respirator with escape provisions.
Vapor-and Gas-Removing Respirators
No protection is provided against particulate contaminants. A rise in canister or cartridge temperature indicates that a gas or vapor is being removed from the inspired air.
An uncomfortably high temperature Indicates a high concentration of gas or vapor and requires an immediate return to fresh air.
Should avoid use in atmospheres where the contaminant(s) lacks sufficient warninq properties (i.e., odor, taste, or irritation) unless equipped with an end-of-service life indicator.
Not for use in atmospheres immediately dangerous to life or health unless a powered-type respirator with escape provisions.
Combination Particulate - Vapor-and Gas-Removing Respirators
The advantages and disadvantages of the component sections of the combination respirator as described before apply.

ATMOSPHERE SUPPLYING RESPIRATORS
Hode_of_Operatjn
LIMITATIONS
Uncontaminated breathing air or oxygen 1$ supplied to the respirator wearer by means of a hose, airline, or from a bottle of compressed air that Is carried by the user.
Except for some air-line suits, no protection is provided against skin irritation by materials such as ammonia and hydrogen chloride, or against sorption of materials such as hydrogen cyanide, tritium, or organic phosphate pesticides through the skin. Facepieces present special problems to individuals required to wear prescription lenses. Use of atmosphere-supplying respirators in atmospheres immediately dangerous to life or health is limited to specific devices under specified conditions.
There are three basic types of atmosphere supplying respirators; hose masks, airline respirators and self-contained breathing apparatus (SCBA).
Mode of Operation
Limitations
1} Hose Mask
1) Hose Mask
Equipped with a facepiece, breathing
tube, rugged safety harness and a Targe diameter heavy/duty nonkinking air supply hose. The breathing tube and air supply hose are securely attached to the harness. A facepiece is equipped with an exhalation valve. The harness has provision for attaching a safety line.
The hose inlet or blower must be located and secured in a respirable atmosphere. The respirable air supply is not limited to the quantity the individual can carry. However, the wearer is restricted In movement by the hose and must return to a respirable atmosphere by retracing his route of entry. The hose is subject to being severed or pinched off.
a) Hose Mask with 8Tower
a) Hose Mask with Blower
^ Air is supplied by a motor/driven Z or hand-operated blower. The wearer f can continue to inhale through the o hose if the blower fails. Up to o 300 feet (91 meters) of hose h length is permissible.
If the blower fails, the unit still provides protection, although a negative pressure exists in the facepiece during inhalation.
Ve-3 (5/01 HUT - 082661
Mode of Operation
b) Demand Type
Equipped with a facepiece only. The demand valve permits flow of air only during inhalation.
c) Pressure-Demand-Type
Equipped with a facepiece only. A positive pressure is maintained in the facepiece.
d) Combination Air-Line Respirator with Auxiliary &e1f-(?ontained Air iuppfy
Includes an air-line respirator with an auxiliary self-contained air supply. To escape from a hazardous atmosphere in the event the primary air supply fails to operate, the wearer switches to the auxiliary self-contained air supply.
3) Self-Contained Breathing Apparatus (SCBA)
Supply of air, oxygen, or oxygen generating materia) carried by wearer. Hormally equipped with full facepiece, but may be equipped with a quarter-mask facepiece, half-mask, helmet, hood, or mouthpiece and nose clamp.
limitations
b) Demand Type Subject to leakage due to negative pressure, in mask during inhalation.
d) Combination Air-Line Respirator with Auxiliary Self-Contained Air Supply
The auxiliary self-contained air supply on this type device allows the wearer to escape from a dangerous atmosphere. This device with auxiliary self-contained air supply is approved for use in atmospheres that are immediately dangerous to life or health.
3) Self-Contained Breathing Apparatus (SCBA)
The wearer carries his own breathing atmosphere. The period over which the device wiil provide protection is limited by the amount of air or oxygen in the apparatus, the ambient atmospheric pressure (service life is cut in half by a doubling of the atmospheric pressure), and work. Some SCBA devices have a short service life (less than 15 minutes) and are suitable only for escape (self-rescue) from an irrespirable atmosphere.
Ve-5
(5/01)
A N A -06043
Node of Operation
1) Closed-Circuit SCBA
) Compressed or Liquid Oxyqen Type
Equipped with a facepiece or mouthpiece and nose clamp- High-pressure oxygen from a gas cylinder passes through a high-pressure reducing valve and, in some designs, through a low-pressure admission valve to a breathing bag or container. Liquid oxygen is converted to a low-pressure gaseous oxygen and ^ delivered to the breathing bag through C a corrugated tube connected to a . mouthpiece or facepiece and a one-way o check valve. Exhaled air passes 5 through another check valve and tube o> into a container of carbon dioxide removing chemical and re-enters the breathing bag. Hake up oxygen enters the bag continuously or as the bag deflates sufficiently to actuate an admission valve. A pressure relief system is provided and a manual bypass system 5 and saliva trap may be provided p> depending upon the design.
3) Soif-Contained Breathing Apparatus (SCBA) - Continued Chief limitations of SCBA devices are their weight or buH or both, limited service life, and the training required for their maintenance and safe use.
Limitation 1) Closed-Circuit SCBA The clo$ed*c1rcuit operation conserves oxygen and penults longer service life at reduced weight. The closed circuit SCBA can not be used in an immediately hazardous atmosphere because negative pressure is created in the facepiece during Inhalation. In addition, the oxygen can lead to an explosion If it comes In contact with oil or grease. Oxygen should never be used In a device unless it is specifically designed for that purpose.

ANA-06044
Hodt of Operation
b) Oxygyn-Genvrating Typt
Equipped with a facepiece or mouthpiece and nose clamp. Water vapor in the exhaled breath reacts with chemical In the canister to release oxygen to the breathing bag. The wearer inhales from the bag through a corrugated tube and one-way check vatve at the facepiece. Exhaled air passes through a second check valve/breathing tube assembly into the canister. The oxygen release rate is governed by the volume of exhaled air. Carbon dioxide In the exhaled breath Is removed by the canister fill.
2) Open-Circuit SCBA
A bypass system Is provided In jE case of regulator failure except
-t i on escape-type units.
o ) Demand Typ*
Equipped with a facepiece or mouthpiece fid nose clamp. The demand valve permits oxygen or air flow only during Inhalation. Exhaled breath passes to ambient atmosphere through a valve(s) In the facepiece.
b) Pressure-Demand Type
Equipped with a facepiece only. Positive pressure Is maintained In the facepiece. The apparatus may have provision for the wearer to select the demand or pressuredemand mode of operation and in which case the demand mode should be used only whendonning or r{ moving the apparatus.
Limitations
1. limitations are the same as the oxygen supplying type described in l.a. This unit is generally lighter, simpler, and cheaper than oxygen supplying closed circuit SCBA.
2) Open-circuit SCBA
The demand type produces a negative pressure in the respiratory-Inlet covering during inhalation, whereas the pressure-demand type maintains a positive pressure in the respiratory-inlet covering during inhalation and is less apt to permit inward leakage of contaminants.

GUIDELINES FOR CONTRACTOR RESPIRATORY PROTECTION PRu.,,:AMS AT DPMC
PREAMBLE
The following guideline outlines the general requirements for contractor per formance in establishing acceptable respirator programs. To assist contractors in fulfilling this obligation, Shell* will make available certain technical resources as outlined below. It is the intent of Shell Management however, that each contractor retain responsibility for program development and com pliance with applicable Health and Safety Standards.
Scope: The requirements of this guideline apply to only those contractors who have an anticipated (planned) use of respiratory protection at the Shell Deer Park Manufacturing Complex.
1. GENERAL
All contractors working at Shell DPMC are to comply with applicable OSHA regulations including 29 CFR 1910.134, Respiratory Protection.
Where respiratory protection is required, respiratory programs which comply with the above regulation generally include:
Employee Training
. Potential Health Hazards of Exposure
. Proper Respirator Selection
Proper Respirator Selection
. Air-Supplied vs. Dust Mask vs. Full-Face Air-Purifying Respirators
. Determinations of Medical Suitability to Use Respiratory Protection
Proper Respirator Maintenance
. Cleaning
. Inspection
Qualitative or Quantitative Fit Testing of Air-Purifying Respirators
. Removal of Facial Kair in the Respirator-Sealing Surface
Responsibility for contractor employee protection and OSHA compliance rests with the management of the contractor. To assist the contractor to meet these obligations. Shell will make available to the contractor certain equipment and manpower resources. Regardless of the contractors utilization of these Shell resources, all contractors required to use respiratory protection at DPMC will be expected to have in place an acceptable respirator program.
HUT-081869
ABS-013525

2. 'AVAILABILITY OF RESPIRATORY PROTECTION EQUIPMENT
With the exception of paint contractors engaged in sandblasting. Shell will make respiratory protective equipment available to all contractors. Sand blasters are to provide their own air-supplied hoods and other protective gear required for this work.
Special respiratory protection required because of process related factors (e.g. potential exposure to chemicals being handled within a unit) will be supplied by DPMC to sandblasters.
DPMC will supply cartridges, air?purifying masks, air-line respirators and other appropriate respiratory protective equipment through the Central Respirator Center or satellite cabinet system. Respirator maintenance for equipment used by contractors will be equivalent to that provided Shell`s employees.
DPMC will supply the required respiratory protective equipment needs of contractors during turnarounds.
Construction contractors including capital and purchase order contractor needs will be reviewed by Industrial Hygiene and Engineering on a caseby-case basis. This applies to lead burner work and tank cleaning.
3. RESPIRATORY TRAINING - DPMC
Safety and Industrial Hygiene will make available to all maintenance contractors a qualified trainer to train one of their supervisory personnel who will be responsible for training the contractors' personnel. Acceptance of this offer by contractors is on a voluntary basis. Records of this training will be retained by the Safety Rep resentative - Contractors.
The Safety Respresentative - Contractors and the DPMC Shel1 Maintenance organization retain the right to periodically audit the respirator training provided to employees of Shell contractors.
Construction contractors will normally not be required to use respirators to install new facilities. In the event of a chemical release, the proper response for.these contractors is evacuation to a safe area. Where respiratory protection is to be used during a project, the employees engaged in this work are to receive the required training by their employer.
Short-term maintenance work requiring the use of respiratory protection such as tank cleaning will be required to verify that the required training has been completed prior to initiating work.
HUT - 081870
ABS-013526

4. QUANTITATIVE FIT TESTING
For contractors utilizing Shell air-purifying respirators. Shell will make available fit testing equipment and a qualified technician to conduct fit testing. Contractor fit testing is to be conducted with the type of mask used by Shell personnel {Scott and MSA).
Contractor fit testing is to be held once per year to pick up new employees and retest old employees. This frequency may be adjusted to accomodate Shell needs and to reflect changes in testing require ments.
Shell is to.provide a copy of our general fit test procedure and testing criteria to the management of each contractor. They are to accept in writing or provide their own testing criteria.
During contractor fit testing, an appropriate respresentative from the contractor is to be present to maintain records and supervise the testing activity.
