Also, in execution of plant riiwsirr olena. proper training in use nf respiratory pmimtivr equipment will aid in the performance of wnnuih and safe rrarue or repair operations. Also, demandtypr air-supplied respirators and demand* type self-conuinrd respirator! operatr under negative prrssure when the wearer inhales. Since tome inward leakage of contaminant may br possible, these types provide much leae protection. When purchasing new airsupplied, self-contained or combination type, pressuredemand should be specified. 74.1 A pressure-demand type aelf-oontained respir ator er air-supplied combination self-contained should be used in stmoepheres containing contaminants which can not be detected by smell or where special precautions must be uken to prevent the wearer from inhaling any trace of contaminant. In this type equipment, a small positive pressure is maintained inaide the facepiece at all tunes, such that if a leak should develop, there would be no leakage of contaminant into the faeepieee. 7.5 A proper seal cannot bo established M the tempi* bars el ey* glaatat extend through the eeallng edge of fulMoce mean*. 7.8 Contact lenses shall not be worn with full-face masks. See S4H. 7.7 All eyepieces in full-face masks approved by the Bureau of Mines will pass the ball drop test, but acme plastic eyepieces may not pass the needle drop tat (S4H). Current schedules of the Bureau of Mines, however, require that eyepiacas shall meet the pertinent raquirsmenu for impact and penetration specified in ths mat rocent ANSI 7117.1 Safety Coda for Eye Protection. 7.7.1 Full-face masks have boon developed with systems for mourning corrective lensa inside the fscepioce. Contact the manufacturers for aeshunee. 7.8 Major problems ia the use of hll-kes masks at low temperatures are poor visibility and fretting of exhala tion valves. Antifog compounds can be used to coat the in side and ouuide of the eyepiece to prevent its fogging down to about JJ*F. Below Q*F, however, antifog com pound will not prevent sever* fogging. Antifog compounds break down and require rcapplieation periodically. 7.8 A half-mask faeepiaee ihould not Interfere with the weerer'a uae of speetaeia or goggles. Proper selection of equipment normally will eliminate arty problem of proper fit when using a combination of half-mask ftcspucs and sectacla or gogglas. 7.10 Persona required us wear respirators most be clean shaven in the ana of the rmpiretor seal. 7.4 A slight negative pressure occurs inside the facepiece of fscr.fitting air-purifying respiratora (Table 1C).

This l>-cause these respirator* do not supply oxygen and therefore do not protect apainst possible oxygen deficien cies. Other reason* for this requirement are that: a. Gas masks are intended for tae with no more than 2 percent by volume of moat toxic gases. a. If high breathing resistance develops. 4.4 Air purifying respirator! should not be used in atmospheres immediately dangerous to life and health or when the contaminant has poor warning properties, ex cept for escape. 4.5 Users should select canisters and cartridges speci fically approved for the toxic~ga* and concentration to be encountered. Canister masks that bear the label "All* Service," "All-Purpose," or "Universal" should not be used for t specific gat or vapor if a canister it available for that specific gat or vapor. 4.1 Although self-contained breathing apparatus or com bination sir-line and self-contained breathing apparatus have no concentration limit in regard to toxicity, many toxie gates and vapors are flammable and the user could be exposed to potential fire or explosion. The 2-pereent concentration limit* spproved for toxic ft* removal with canister-type masks is within the flammable range for tome gstet. Work in atmospheres in or near the flam mable range ia prohibited. When the possibility of flam mable atmospheres exists, a cheek ahould be made with an exploaimeter and permisaable concentration* con firmed prior to entry.

The air in the self-contained unit of the combination air-line respirator and sdf-eontamed breathiag apparatus shall be uaad only for egress in event the hose-line supply of air ia intti. opted- The volume of this exit supply may vary for diffartat applications, but shall be ample to allow the worker sufficient air to escape from the coataminated area, la any case, this supply shall not be less than 3 minutes. 1.14 Aa uneontaminaud supply of air must be assured wbtn using a hose mask with blower. 5.1.5 Schedule 13E of the U. S. Bureau of Minee on self-contained breathing apparatus requires a remain ing service-life indicator or warning for compressed breathing air (except for self-rescue, which has a mansmum rated service time of 30 minutes). Some equipment 'now on plants may not have these alarms.Thete eaa and should be obtained from equipment suppliers for appara tus not so equipped. 5.1.5.1 When the device is a combination selfcontained breathing apparatua and air-iine respirator (supplied-air respirator), either a manual or automatic veivris) shall be provided to change to the self-contained air supply if the air-line supply fails, and to prevent the wearer breathing contaminated air horn the outside atmosphere. If a manual valve is provided, k shall be easily operable and located ia a poetliaa which ia con venient to the weaker. If no automatic valve is provided, a warning also shall be provided to alert the wearer that be ia breathing from the seif-contained air supply, (1) when hit normal air-iine supply fails, or (2) whet the self-contained sir supply falls below 95 percent of its full container pressure. A quick disconnect and cheek valve shall be provided between the apparatus and the air-line supply hose to permit ready escape from the area, and to prevent lost of breathing air from the device or inhaling the surrounding atmosphere. respectively. 5.1.1 \pparatus classified for 30-minule service time, or longer, should be used for entry into an irmpirable atmosphe.'t.

If a munuul valve is provided, it shall be easily oprruble and located in a position which is con venient to the weurer. If an automatic valve is provided, a warning also shall be provided to alert the wearer that he is breuthing from the self-contained air supply.(1) when his normal air-line supply fails, or (2) when the -elf-contained air supply fails below d.> percent nf its full container presaure. \ quick disconnect and cheek valve shall be provided between the apparatus and the air-linr supply hose to permit ready escupe from the area, and to prevent lost of breathing air from the device or inhaling the surrounding atmospiiere. respectively. 5.2 Table 3 lists the hazards and the respirators that are recommended to afford respiratory protection against them. By reference to this table, and by considering the foregoing factors, the user can determine the type of respirator that should be used. 6. PRECAUTIONS 6.1 Purchased cylinders of breathing air should be analy ted for ox v grn and carbon raonotvkic content before use. This analysis normally should be done by die plant (tee S3T |. Mso. the water content of cylinder air used for air masks should be below the dew point for thr lowest prob able temperature to be encountered. This is necessary to prevent freeirup and stoppage of uir flow to the mask.

Also, in execution of plaal disaster plana, proper training in use of respiratory pro- tectr-e equipment will aid in the performance of imooth and safe rescue or repair operations. * 6.5 A negative pressure occurs inside the facepiece of face-fitting air-purifying respirators (Table 2); Care must be taken to obtain an affective spat between the facepiece and face to prevent inward contaminant leakage. Also, demand-type air-supplied respirators and demand- type self-contained respirators operate under negative presnure when the wearer inhales; some inward leakage of contaminant may be possible. A pressure-demand type self-contained respirator may be used where special pre cautions must be taken to prevent the wearer from in- balii g any trace of contaminant. (A email positive pres sure is maintaiatd at all times and. even if a leak should dcveiop. there would be ao leakage of contaminant into the fiicepisce.) 6.6 A proper tool cannot bo established d the temple bars of eye flosses extend threufh the scaling edge of fulMsce masks. 6.6.1 All eyepieces! in full-face masks approved by the ,3ureau of Mines will pots the ball drop teat, but asms plastic eyepieces may not paaa the needle drop last (S4H ). Current ecbeduWs of tbe Bureau of Mines, haw. ever, require that eyepieces shall meet the pertinent re quirements for impact and penetration specified in the most recent USA Standard Safety Cede for Eye Protection. 6.6.2 Aa a temporary measure with full-face pieces, glasses with sbnst ternpit bare or wahoat temple bars may be taped to the wearer's bead.

Proper selection of equipment normally will eliminate any prob lem cf proper Gt wbeu eiiog a combination of hab-raoak facep ece and spectacles or goggles. 6.7 Conventional respirators do not constitute an abso lute barrier to transmission of speech. Ihe respirator exhalation valve usually provides a satisfactory pathway for speech transmission over short distances m relatively quiot areas. Speech transmission devices are available. (Caution: check for acceptability of dectrieal classification for use in haxnrdous areas.) 6.1 Major problems in the use of full-face masks at low temperatures are poor visibility and fretting of exhala tion valves. Aniifog compounds can be used to coat the inside of the eyepiece to prevent its fogging dow n to about 32 F. Below 0 F, however, aatifog compound will not prevent severe fogging. 6.9 Hoses for air supply should be selected to resist chemicals to which they may be exposed. 7. CARE 7.1 Oonerol. A ceatralittd maintenance, cleaning, and storage station should be used to care for respiratory protective equipment. 7 .2 Procedures Applicable to All Respirator*-' P 7.2.1 Inspection. All respirators shall be inspected at regular intervals to make sure that they are ready to use. It is good practice to integrate tbe respiratory' and lire-extioguieber inspection end maintenance program. TAJ Maintenance. When it la necessary to replace worn or deteriorated parts, only those made specifically for the device should be used; sad the repair work should be accomplished by traistd pereoanti. For most plants, it is preferable that para of this type be replaced os a unit or returned to the manufacturer for repair. 7.2J Cleaning and Disinfecting. Respiratory pro tective equipment, except canisters and cartridges, should be dcaatd and disinfected after taeh esc. unless ataignsd to individuals. Respiratory equipment eon be clsaatd with detergent and lukewarm water (lese than 123 F) by hand brushing or agitation in a washing machine, rinsed, and dried. The qaaicraary ammonium salt dis infectants* are recommended for ttcriiitiag respiratory devices. Rinse completely in clean, warm water. Aseure thorough drying of mask and demand apparatus after cleaning to prevent freesing if used m cold weather. 7.2 A Storage.

SCOPE This standard provides information for the selection, uar, and care of respiratory protective equipment (respi rators). The term "respirator" in this standard is used inclusively and applies to atmosphere-supply ing and airpurify ing dev ices that provide breathable air to thewenrer wi hin the limits of the equipment, whatever the source of ait. This standard does not apply for exposure to air borne radioactive contamination for which special con sideration may be necessary. Z GENERAL Zl Respirators- protective equipment should not be used as a substitute for adequate exhaust ventilatiqir'dr other engineering control methods. ' Z2 Respiratory protective equipment shall be worn at all times where the atmosphere may be harmful to em ployees due to unusual conditions, and where work is necessary in contaminated or oxygen-deficient. confined areas. ZZ.1 When the air is deficient in oxy pen. the sy mptoms range from increased volume of breathing and ac celeration of pulse rate to unconseiousness and death. depending upon oxygen content and the degree of a per son's activity. Unconsciousness is immediot# whan a man beeathas pur# niteagen and daadt may follow in a fow minutes. XZ.2 An oxygen deficiency may indicate a haxard in (ddition to inert gas: eg. flammability (see 1.1). skin toxicity, or absorption through the skin, particularly hy drogen cy anide. Threshold limit values (TLY's) of air contaminants are given in Standard S2T. Portable oxy gen and toxic-gas detectors are covered in Standard S3T. 2.3 Pure oxygen shall not be used in atmospheresupplying respirators. the Superintendent of Documents. l\ S.

This is because these respirators requite at least 16 percent oxygen in the air. Other irasons for this requirement are that (a) gas masks are ntended for use with no more than 2 percent of most toxic gases, sad (b) chemical cartridge respira tors srr approved for no more than 1000 ppm by volame of orgs nic vapor in air. 4.3 L se of canister masks that bear the labels"AltService." "All-Purpose," or "Universal" is prohibited. 4.4 Although self-contained breathing apparatus aad hose mask with blower have no concentration limit ia regard to toxicity, many toxic gases and vapors are flammable snd the user could be exposed to a potential fire or explosion. The 2-percent concentration limits ap proved for toxic gas removal with canister-type masks may be w thin the flammable range for some gases. Standard F6J provides information and instructions for use of portable flammable vapor and gns detectors. 3. SELECTION S.1 In gene_ral. in chooaing a respirator, tits following factors should be considered: (a) nature of the hazard, (b) severity of the hazard, (c) type of contamiaant. (d) concentration of the contaminant, (e) period protection is required. (0 location of the contaminated men with respret to s sourer of reepirablc air. (g) expected activity of the wearer, (h) operating eharacterietici and limita tions of tin.* available rtepiralars, (i) safety regulations of state or local governments (see Table 2). The latter condition is defined as one from which a worker cannot escape uninjured aititoui respiratory pro tective equipment. The air in the self-contained unit of the combination air-lint respirator and self-contained breath ing apparatus shall be used only for egress in event the hose-line supply of air is iaterrupied. The volume of this exit supply may vary for different applications, but shall be ample to allow the worker sufficient air to escape from the contaminated area.- In any case, litis supply shall not be less than 3 minutes. 3.1.4 An uneontsminsted (apply of sir must be assured when using a bote mask with blower. 5.1.5 Schedule 13E of the U. S. Bureau of Mines on self-contained breathing apparatus requires a remain ing service-life indicator or warning for compressed breathing air (except for self-rescue, which has a mtmimum rated service lime of 30 minutes). Some equipment now on plants may not have these alarms. These can and should be obtained from equipment suppliers for appara tus not to equipped. 5.1.5.1When the device it a combination selfcontained breathing apparatus and air-lint respirator (tuppiied-air respirator), either a manual or automatic vaivtft) shall be provided to change to the self-contained air supply if the air-line supply fails, and to prevent the wearer breathing contaminated air from the outaide atmosphere. If a manual valve it provided, it shall be easily operable aad located io a position which is con venient to the wearer. If aa automatic valve is provided, a warning also shall be provided to alert the wearer that he is breathing from the self-contained air supply. 11) when hia normal air-line supply fails, or (2) when the Mif-eontained air supply falls below 95 percent of its full container pressure. A quick diecoancct and check valve shall bt provided lietween the apparatus snd ths air-lias supply bote to permit ready escape from the area, and to prevent low of breathing air from the device or inhaling tho surrounding stmosphtrs. respectively. 3.1.1 Apparatus clasaified for 30-minule service time, or loiger. should be used for entry into an irreepirabit atmosphere, la renaia cases. lS-minult units may be permitted, depending upas local condiiioai. 5.2 Table 3 lists the haiarde and the respirators that art recommended to afford respiratory protection againat them.

A pressure-demand type self-contained respirator may be used where special pre cautions must be taken to prevent (be wearer from in haling an> trace of contaminant. (A small positive pres sure is maintained at all times and. even if a leak should develop, there would be no leakage of contaminant into the fi.cepwce.) 6.6 A proper saai cannot ha astoblishad if too tample hors of ay* glasses eutend through the seeling edge of full-fuse masks. 6.6.1 All eyepieces in lull-face mailt approved by the Bureau of Mines will pass the ball drop teat, but some plastic eyepieces may eel pass the arrdJc drop wet (S4H). Current schedules of the Bureau of Mimes, how ever. require that eyepieces shall meet the pertinent re quirements for impact and penetration specified in the meet rectot USA Standard Safely Code for Eye Protection. 6.6.2 As a temporary measure with full-face pieces, glasets with short temple bars or without tample hart may be taped to the wearer's hand. Fall-face math* have been developed with systems for mounting corrective leases inside the facepiece. ti.64 A kslf-toask facepiece should not interfere with ihr wearer's use of tpectaeias or goggles. Proper selection of equipmeol normally will eliminate any prob lem of proper fit whea uaiag a combination of half-mash facepiece and spectacles or goggles. 6.7 Conventioaal respirator* do not constitute an abso lute barrier to transmission of speech. The respirator exhalation valve usually provides a satisfactory path* at for speech transmission over short distances in relatively quiet areas. Speech transmission devices are available. (Caution; check for acceptability of electrical classification for use in hasardoua areas.) 6.6 Major problems ia the use of full-face masks at low temperatures are poor visibility and fretting of exhala tion valves. Aatifog compounds tan be used to coat the inside of the eyepiece to prevent its fogging down to about 32 F. Below 0 F, however, aatifog compound will not prevent severe fogging. 6.* Hoses for air supply should be selected to resist chemicals to which they may he exposed. 7. CARS 7.1 Sonnrol. A centralized mtmtenance. cleaning, and storage station should be used to care for respiratory protective equipment. 74 Procedural Applicable to All Raapiratom-' 9 74.1 Inspection. AU respirators shall be inspected at regular intervals to make sure that they are ready to use. It is good practire to integrate the respiratory and firr-exitoguisber tospection and matotenaaee program. 7.24 Maintenance. Then It is necessary to replace worn or dtteriorated pans, only those made specifically for the device should be used; and tbe repair work should be accomplished by trained personnel. For most plants, it is preferable that pans of this type be replaced as a unit or returned to the manufacturer for repair. 7.24 Claaning and Disinfecting. Respiratory protsctivr equipment, except canisters and cartridges, should bt denned and disinfected after each me, unless assigned to individuals. Respiratory equipment eon be cleaned with detergent and lukewarm water (less than 125 F) by band brushing or agitation ia a washing machine, raised, and drfed.

By reference to this table, and bv considering the foregoing factors, the user can determine the type of respirator that should be used. 5. PRECAUTIONS 6.1 An extensive liat of instruction in aae aad precautions for eaeh type of respirator ia given ia the previously referenced ASA Z2.1. Some pre cautions are given in Table 2 under headings of Limitations aad Remarks. 4.2 The air-purifying respirators, ie, canister gas Jt.2 The manufacturer's instructions should be masks, chemical citrtridge respiratars, end mechani posted with the respiratory device. Where these cal filter respiratars (Table 2C) shall net be used art not available, precautions of ASA should he fer raseua work, er fer emergency week ef eny nature. posted at the respiratory storage locatioas. This is because tiicac respirators require at least 16 percent oxygen in the air. Other reasons for this requirement are that (a) gas masks are intended for use with no more than 2 percent of most toxic gases, and (b) chemical cartridge respirators are approved for no more than 1000 ppm by volume of organic r in air. 6.3 All persons who may have occasion to aae respiratory devices, or cause them to be used, should be properly trained in their use before cir cumstances require that thay use them to protect their lives and the property of the Company.

In demand-typt (Tshle 2B), the cylinder praaeute should he cheeked periodically and brought to'reted pres sure if necessary. Recharge aftdr each use, folowing manufacturer's instructions. Follow manu facturer's instmetions on tightness tests for selfcontained respirators. 7.3.2 Nate Maths. Check ths blower period ically for proper operation. Check hose for wear ind tear after each use and steam clean when sectssen. Keep hose capped when not in ase to prevent rntrance of dust or other costaminants. 7.3.3 Air-Line Respireters. The facepiece should be serviced after each use, as for all other espirators. The flow control valves should be mepected after each ssa asd cleaned and repaired, if necessary. Air-line hose should be checked for wear and tear after each use and be steam cleaned when necessary. See Standard Sill on sirsupply system. 7.3.4 Gas Masks. The canister should be re- ^ pieced at least annuslly whether or not it has been used. At the time of replacement of canister, the face-piece, harness, hose, and headband should be examined carefully for any signs of leak or dete rioration, and should be replaced if aay ere found. 7.3.J JsTATTeseuers. Frequent inspection is the most important phase oT the maintenance pro gram with this type of equipment because the equipment is seldom used but always must be ready. 7.3.6 Chernies/ Cartridge Respirators. Chemi cal eartridgaa should bo ebaaged when the wearer detects the odor or irritating offset of the eontamiaent. In pianto with caatralisad mainttnaaca sta tions, eartridgaa sometimaa are discarded after a given period of uee (booed oe group experience); but, in mout eases, the wearer is responsible for discarding and replacing eartridgaa in his respira tor. Particular car* should be exercised in the storage of ehomieal cartridges because they usually dnteriorate if exposed to exeoso moisture and to seous air contaminants. Cartridges should not stored in the area where it is necessary for ths workmen to not ehomieal cartridge respirators. - 7.3.7 Mechanics/ Pi/lee Respirators.

Air-line hoae capped when not in uae to prevent entrance of dust or other contaminants. - s.3.4 Air-LIn* Respirators. The facepiece should be serviced after each uae. or at the end of the ahift. as for all other respirators. The flow control valves should be inspected after each uae and cleaned and repaired, if necessary. Air-line hoae should be checked for wear and tear after eaeh use and be cleaned when neceasary. See SLH on air-supply system. I3.S Sslf-Rsacusrs. Monthly inspection is the moat important phase of the maintenance program with this type of equipment because the equipment is seldom uaed but must always be ready. 8.3.8 Chunleal-Cartrltig* Respirator* 8.3.8.1 Cartridges should be discarded after a predetermined period of uae. See S9H. 8.3.7 Mechanical Fitter Rsepiratore. Mechani cal fillers of the "tiuow-swsy" type should be discarded when the breathing resistance becomes bothersome to the wearer at the end of the work ahift.

Some precaution* are given fiTTable 1 under heading* of Limitation* and Remarks. 73 The manuiaernrer's tnatructiona or precaution! of the ANSI standard ihould be poated with the reapiratory device. 7.3 All p*raofta who may hov* occaaion to tie* reapiratory devices, or eauae them to b* uaed, ahall be property trained In Ihslr'uae. Also, in execution of plant disaster pinna, proper training in uae of retpiralory oroteetive equipment will aid in the performance of smooth and safe rescue or repair operation*. 7.3.1 Trailing in the uae and fit totting of respirator* is an'essential part of a reapiratory protection program and it itpecifted in OSHA regulations. Training hall be completed prior to fit testing. See S8H for fitleiung protocols Additional reference* are lilted in section 9. 73.2 A alight negative preaaore occur* inaide the facepiece of face-fitting air-purifying rajpirator* (Table 1C). Care must be taken to obtain an effective seal be tween the facepiece and face to prevent inward con taminant leakage. Alto, demand-type air>*upplied reapirator* and drmand-type self-contained respirators operate under negative pressure when the waarer inhalaa. Since some inward leakage of contaminant may be poaaible. these t;q>e* provide lea protection. When pur chasing new air-aupplird. aelf-eonlained or combination type, prrtaurc demand should be specified. 7.4 A pressure-jrinand type aelf-euntained respirator or air-supplied combination (sr-lf-rnnuitied) should lie used in atmnapherra containing contaminants Which cannot be detected liy amr I, irritatiiHi, or taste, or where special nrrrautioiw mul la- taken to prevent the wearer from inhaling- any tra, - of rontaminant.

Contact the manufieturers for assistance. 73 Problem* in the use of self-contained breathing ap paratus (SCBA) at low temperatures include failure of exhalation valvat due to frosen exhaled moisture and failure of the regulator or low air pressure alarm. Theae problems can be minimised by: . Using only air with low- moisture content b. Installing a notecup in the mask e. Thoroughly drying masks after cleaning d. Keeping SCBA* in a warm location between uses (if practical) - Visually checking pressure gages for low air supply f. Following manufacturer'* instruction* for use in subfreextng environment* Antifog compound* can be used to coat the inside and outside of the facepiece to prevent its fogging, down to about 32*F (0*C). Below 0*F (-18*0. however, antifog cum pounds will not prevent severe fogging. Antifog compounds break down and require reapplicalion periodically. 73 A half-mask facepiece should not interfere with the wearer's use of spectacle* or goggles.
