Effective July 7, 1972, the Occupational Safety and Bealtb Administration of the Department of Labor promulgated regulations addressing employe exposure to asbestos. "Asbestos" as defined in the standard includes chrysotile, amosite, croeidolite, tremolite, anthophyllite, and actinclite. 3he standard applies to operations where asbestos or asbestos-containing materials such as but not necessarily limited to asbestos cement, mortar, coating, grout, plaster or similar materials are handled, mixed, applied, removed, cut, scored or otherwise worked.
Exposure limits applying to asbestos fibers longer than 5 microns are bb follows:
a. Effective 7/7/72 - An 8-hour time-weighted average (3WA) not to exceed 5 fibers per cubic centimeter of air.
b. Effective 'l/lj'jS - An B-hour 1VA not to exceed 2 fibers per cubic centimeter of air.
c. A "Ceiling Concentration" of 10 fibers, above which no employe shall be exposed at any time.
Monitoring requirements are such that in areas where asbestos fibers are released a determination shall be made as to whether every employe's exposure to asbestos fibers is below the limits addressed above. Such sampling shall be done at inter vals of no greater than 6 months in cases where employe exposure to asbestos "may reasonably be foreseen to exceed the limits prescribed...".
Controls and requirements for those operations in which employes are exposed to concentrations in excess of the exposure limits include:
a. personal protective equipment b. local exhaust ventilation c. specific work practices d. change rooms e. labels and placards f. specific cleaning and waste disposal techniques g. employe notification h. medical examinations i. recordkeeping
Copies of complete standard are available from;
Superintendent of Documents U.S. Government Printing Office Washington, D.C. 204oe
Further information regarding this standard may be obtained from Industrial Hygiene, 322-0210.

OSHA PROGRAM DIRECTIVE #300- J 6 October II, 1978
TO: REGIONAL ADMINISTRATORS/OSHA
Subject: 29 CFR 19J0.J00l(j)(2) or (3) or (4). Minimum Airborne Fiber Concentration for Initiating ana lonlinuing tions.
1. Purpose
f
The purpose of this directive is to piovide uniform
inspection and compliance procedures for the medical
examination requirement in the asbestos standard.
29 CFR 1910.1001 (j )(2). or (3) or (4).
2. Documentation Affected
This directive supplements and provides reference for
the OSHA Industrial Hygiene Field Operations Manual
(IHFOM) and the OSHA Field Operations Manual
(FOM)
3. Huckgrmtnd
In 29 CFR l9IO.IOOI(j)(2). or (3) or (4). Medical ex
aminations. the term ". . . exposed to airborne concen
trations of asbestos fibers. . . ." has been the subject of
considerable discussion and debate as to the meaning or
interpretation of "airborne concentrations."
4. Action
a. Definition
In 29 CFR 19)0.1001 (j)(2), or (3) or (4). Medical ex
aminations, the term "... exposed to airborne concentra
tions of asbestos fibers...." is administratively interpreted
to mean exposed to a minimum of 0.1 asbestos fibers longer
than 5 micrometers per cubic centimeter of air. as deter
mined by the sampling method prescribed in section 4.c. of
this directive. The phrase "fibers longer than 5 micro
meters per cubic centimeter of air" shall hereafter be abbre
viated as "fibers/cc."
b. Scope and applicability.
Medical examinations as per 29 CFR 1910.10010K2).
or (3) or (4) will be required for any 7- to 8-hour time-
weighted average concentration of 0.1 fibers/cc. or for a
greater concentration.
c. Sampling information.
(1) Sampling procedures will follow Chapter X of
the IHFOM.. with the additional guidance of 4.c.(2)
and (3) of this directive.
(2) Exposure to asbestos dust with low levels of con
tamination (e.g.. mixed with other minerals).
(a) For exposures to dust that is mostly asbestos and
is expected to be below the permissible exposure limit,
the same filter should be used for the entire shift, but no
longer than 8 hours
(b) For exposures expected to be at or above the per
missible exposure limit, several samples max be re-

t , quired during the shift to avoid overloading the fillers.
' (3) Exposures to asbestos dust with high levels of
contamination. (a) Several samples may be required during the shift
to avoid overloading the filter. (b) Filters should be changed only after a minimum
of 1 hour of sampling time for exposures expected to be close to 0.1 fibers/cc. Seven or eight 1-hour samples can be collected during the day.
d. Examples of types of violations.
(1) Where an employer does not provide the required medical examinations, and an employee is exposed to 0.1 or more fibers/cc. it would be considered a "serious" violation of 29 CFR 1910.1001(j)(2). or (3) or (4).
(2) For definitions and guidance on "repeated." "will ful." or a "failure to correct" violation, see the FOM, Chapter VIII.
5. Effective Date This directive is effective immediately and will remain in effect until further notice.

C Camellation This directive cancels OSH A-lnstruction CPL 2-2 10. CPL 2-2 14 and the IHFOM dated June 1976.
D. Action. 1. All policies and procedures described in the IHFOM should be initiated as of April 30. 1979.
2. Two copies of this instruction appear in the IHFOM. One of these should be filed in new OSHA Directives System Binders
E. Federal Program Change. This directive describes a Federal program change which affects State programs. Each Regional Administrator shall:
I. Ensure that this change is forwarded to each State designee
2 Explain the technical content of the change to the State designee us requested.
3. Ensure that the state, within 30 days, submits a plan supplement, a timetable for adoption of such a supple ment. or reasons why it is not necessary for the State to change us plan Stales must ndt be allowed more than 6 months from the date of notification to formally submit the plan change supplement to the Region.
4. Review policies, instructions, and guidelines issued by the State (o determine that this change has been com municated to state program personnel.

OSHA Instruction CPL 2-2.25 May 8. 1979
Subject: Sampling Techniques and Laboratory Sub mittal Strategies
A. Purpose. This directs OSHA Compliance Officers to lake samples in an efficient manner and prioritize samples submitted to the laboratory. It directs labora tory personnel to be selective about the samples analyzed and establishes a quality control program to ensure meaningful samples are not disregarded It also estab lishes procedures to submit screening data to OMDS
B Scope. This instruction applies OSHA-wide. C. Action. I. Field Compliance Officers. a Determining Types of Samples. Before conducting full shift sampling for chemicals identified in Table I. screening samples should be taken with detector tubes or other currently available direct reading instruments When screening samples indicate exposures of less than 50 percent of the PEL, further sampling shall not be re quired. Detector tubes in Table I will be made available to the Regions from the Cincinnati Maintenance and Calibration Laboratory

b. Recording Screening Results. The total number of screening tests taken for the above substances must be recorded and transmitted to the National Office for MIS purposes As an interim measure, the Direct Reading Data OSHA-93 Form will be used for this purpose (see IHFOM Chapter 14) Although the Direct Reading Data Form was not designed with screening in mind, this form lends itself to recording the data required to determine by substance the total number of screening samples taken.
When the Direct Reading Data OSHA-93 Form is used to report screening tests the following information will be recorded on the form:
