Minimum Airborne Fiber Concentration for Initiating and Continuing Asbesios_ Medical Examina tions. - ~............. '' 1. Purpose The purpose of this directive is to provide uniform inspection and compliance procedures for the medical examination requirement in ythe asbestos standard, 29 CFR 1910.100 l(j){2). or (3) cy (4). 2. Documentation Affected ; This directive supplements arid provides reference for the OSHA Industrial Hygiene Field Operations Manual (IHFOM) and the OSHA Field Operations Manual (FOM). 3. Background In 29 CFR 1910.1001{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 1910.100l(jX2), or (3) or (4). Medical ex aminations. the term ". . . exposed to airborne concentra- dons 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 1910.1001(jX2), or (3) or (4) will be required for any 7- to 8-hour time- weighted average concentration of 0.1 fibers/cc, or tbr k' 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 may be re- 1 -vMti* j exhibit Occupational Safety & Health Reporter 36 iuGrow0""*' INDUSTRIAL HYGIENE PROGRAM DIRECTIVES quired during the shift to avoid overloading the filters. (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 1910.10010(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. OSHA Instruction CPL 2-2.20 April 2, 1979 Subject: Industrial Hygiene Field Operation Manual A. Purpose. This instruction establishes the revised Industrial Hygiene Field Operation Manual (IHFOM) and incorporates it into the OSHA Directives System. B. Scope. This instruction applies OSHA-wide. C. Cancellation. This directive cancels OSHA-Instruction 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: 1. Ensure that this change is forwarded to each State designee. . 2. Explain the technical content of the change to the State designee as 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 its plan. States must not 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 to determine that this change has been com municated to state program personnel. Routine moni toring activities (accompanied inspections, spot check visits, and case file reviews) shall also be used to deter mine if this change has been implemented in actual per formance. S-143 24:9459 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 take 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. 1. Field Compliance Officers. a. Determining Types of Samples. Before conducting full shift sampling for chemicals identified in Table 1. 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 1 will be made available to the Regions from the Cincinnati Maintenance and Calibration Laboratory. Table 1 Detector Tubes A vailablefrom MCL Substance Code 1. Acetone , 0040 2. Benzene 0320: 3. Ethyl Alcohol 1060 4. Formaldehyde 1290 5. Isopropyl Alcohol . 1560 6. Methyl ethyl Ketone 0430 7. Methyl isobutyl Ketone 1385 8. Perchloroethylene (tetrachioroethylcne) 2020 9. Trichloroethane (methyl chloroform) 1720 10. Trichloroethylene 2490 11. Toluene 2460 12. Vinyl Chloride 2580 13. Methylene chloride 1730 14. Xylene 2590 b. Recording Screening Results. The total number of . screening tests taken for the above substances must be recorded and transmitted to the National Office fbr 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: 1. Print the word "SCREEN" at the top of the form. 2. Complete the following items on the form. See the example on Attachment A. Item 7. Establishment Name 6-21-79 Published bv THE BUREAU OF NATIONAL AFFAIRS, INC., WASHINGTON, D.C. 20037 . 50130225 31
