[FR Doc.72-8578 Filed 6-6-72:8:50 am] Title 29--LABOR Chapter XVII--Occupational Safety and Health Administration, Depart ment of Labor PART 1910--OCCUPATIONAL SAFETY AND HEALTH STANDARDS Standard for Exposure to Asbestos Dust On December 7, 1971, an emergency temporary standard concerning exposure to asbestos fibers was published in the Federal Register (36 F.R. 23207). In ac cordance with section 6(c) (3) of the Williams-Steiger Occuptaional Safety and Health Act of 1970, a notice of proposed rulemaking regarding a permanent standard for exposure to asbestos fibers was published in the Federal Regisier on January 12, 1972 (37 F.R. 466). The no tice invited interested persons to submit both orally and in writing, data, views, and arguments concerning the proposal. On or about January 24,1972, the Ad visory Committee on Asbestos Dust was established and requested to make writ ten recommendations with regard to the proposed standard on asbestos. On or about February 1, 1972, the Department of Health, Education, and Welfare trans mitted to the Secretary of Labor a cri teria document containing Recommenda tions for an Occupational Exposure Standard for Asbestos by the National Institute for Occupational Safety and Health (NIOSH). Public notice was given of the receipt of the recommendations and their availability for inspection and copying. On or about February 25, 1972, the Advisory Committee on Asbestos Dust submitted its written recommendations to the Assistant Secretary of Labor for Occupational Safety and Health. Pursuant to the notice of rule making, a hearing was held on March 14 through 17,1972, for the purpose of receiving oral data, views, and arguments concerning the proposed standard. On or about March 31,1972, the presiding hearing ex aminer certified to the Assistant Secre tary of Labor for Occupational Safety and Health the record of the proceeding. The record includes prehearing written comments, a transcript of the oral pres entations made at the hearing, and nu merous exhibits received during the course of the hearing or within the pe riod allowed after the close of the hearing. The proposed standard dealt with (1) permissible concentrations of asbestos fibers; (2) methods of compliance; (3) warning signs; (4) monitoring; (5) med ical examinations; and (6) recordkeep ing. Each of these major proposals elic ited comments, arguments, objections, and counterproposals. They all have been examined and considered. 1. Acceptable concentrations of asbes tos dust. The proposed standard would limit occupational exposure to 8-hour time-weighted average (TWA) airborne concentrations of asbestos dust not ex ceeding five fibers longer than five micrometers per milliliter. Concentra tions above five fibers but not to exceed 10 fibers (ceiling concentration) would be permitted up to 15 minutes in an hour, but for not more than 5 hours in any one 8-hour day. NIOSH in effect has recommended that the five-fiber TWA and 10-fiber peak concentrations be permitted only for 2 years; thereafter, TWA concentra tions should be not more than 2 fibers per cubic centimeter (cm.*) of air, and peak concentrations should not exceed 10 fibers/cm.*, with no time restriction. Numerous objections and counterpro posals have been made, with regard to both the limits of asbestos fiber concen trations and the time periods to comply with them. Some, for example, have rec ommended return to a 12-fiber standard of an earlier day; i.e., a level adopted under the Walsh-Healey Public Con tracts Act in 1969. Others have recom mended a two-fiber standard to become effective in 6 months, then a one-fiber standard for 2 years, and finally a zerofiber standard after 3 years. These rec ommendations give a fair indication of the wide spread of the counterproposals. No one has disputed that exposure to asbestos of high enough intensity and long enough duration is causally related to asbestosis and cancers. The dispute is as to the determination of a specific level below which exposure is safe. Various studies attempting to establish quantita tive relations between specific levels of exposure to asbestos fibers and the ap pearance of adverse biological manifes tations, such as asbestosis, lung cancers, and mesothelioma, have given rise to controversy as to the validity of the measuring techniques used and the relia bility of the relations attempted to be established. Because of the long lapse of time between onset of exposure and biological manifestations, we have now evidence of the consequences of exposure, but we do not have, in general, accurate measures of the levels of exposure oc curring 20 or 30 years ago, which have given rise to these consequences. There are also controversies concerning the relative toxicity of the various kinds of asbestos, and varying hazards in dif ferent workplaces. It is fair to say that the controversy has centered in the area between a two- fiber TWA concentration and five-fiber TWA concentration, with variations on the time needed for compliance. Many employers support a five-fiber TWA. Most medical opinion is divided between a two-fiber standard and a five-fiber standard. In view of the undisputed grave con sequences from exposure to asbestos fibers, it is essential that the exposure be regulated now, on the basis of the best evidence available now, even though it may not be as good as scientifically de sirable. An asbestos standard can be re evaluated in the light of the results of ongoing studies, and future studies, but cannot wait for them. Lives of employees are at stake. It is concluded that there should be one minimum standard of exposure to asbestos applicable to all workplaces ex posed to any kind, or mixture of kinds, of asbestos. Reasons of practical ad ministration preclude a variety of stand ards for different kinds of asbestos and of workplaces. Also, while the evidence tends to show that crocidolite, for in stance, is more harmful than chrysotile, the evidence is not sufficient to establish separate standards for varieties of asbestos. Because there must be one standard governing exposure to all varieties of asbestos, and in workplaces apparently more hazardous than others; because some present employees with regular ex posure to asbestos have probably al ready accumulated great doses of asbes tos fibers, due to higher levels of ex posure in the past; because it appears that levels of exposure which may be safe with regard to asbestosis are not safe with regard to mesothelioma; be cause the statute requires the protection of every employee, even of one who may have regular exposure to asbestos during a working life which may reach, or even exceed, 40 years; and because of several other considerations which have been urged and are reflected in the record of the proceeding, the conflict in the medi cal evidence is resolved in favor of the health of employees. As of July 1, 1976, TWA concentrations of asbestos fibers longer than 5 micrometers will not be allowed to exceed two fibers/cc., with a ceiling value of 10 fibers/cc. The current TWA concentrations of five fibers, and FEDERAL REGISTER, VOL 37, NO. 110--WEDNESDAY, JUNE 7, 1972 NOTiCF; This mafct'W k by oepyrtghl tow (TS* IT U.8.

Medical examinations. The pro posed standard would only require an appropriate medical examination on a periodic basis. The generality of the pro posal has attracted many objections and also many helpful comments. The recom mendations of NIOSH and of the Advi sory Committee on Asbestos Dust were reasons the standard provides that em ployers may have a restricted access to some medical information. On the other hand, there is no inten tion to allow employers to abuse medical information obtained pursuant to the Act, to the detriment of employees. Therefore, the administration of the medical records requirement will be closely watched, and, in cases of abuse, general rule, it would be difficult to im plement. Personal protective equipment, such as respirators, cannot be relied upon because, among other reasons, they may be so uncomfortable as to be bur densome, except for short periods of time. Therefore, it is expected that res pirators and shift rotation will be used during the period necessary to install en much more specific with respect to both frequency and type of medical examina tions to be required. The comments vary as to the class of employees to be ex amined and as to the frequency of the examinations. The adopted standard requires medical examinations both at the beginning and the termination of employments exposed appropriate action will be considered. ' The issues discussed above are believed to be the major ones. Numerous other is sues have been raised in the rulemaking proceedings. Some have been referred to incidentally. Many recommendations, for instance, about work practices, are so obviously meritorious that their adop tion needs no exposition here. Other gineering controls and to train employ ees in sound work practices, but, after technological compliance has been achieved, their use must be limited to special work situations and emergencies. Where both are practicable, shift rota to concentrations of asbestos fibers, and also requires annual medical examina tions of every employee exposed to air borne concentrations of asbestos. It has been pointed out that in certain indus tries, such as construction, an employee recommendations and many objections have not been adopted for a variety of reasons which should be manifest. Sev eral, for instance, have recommended the use of respirators only pursuant to a variance, or in cases of emergency and tion is required. 3. Labeling. The proposed standard stopped short of requiring labeling as bestos and asbestos-containing products. The proposed standard would have re quired only warning signs at locations may work for several employers during the same year. Accordingly, the standard does not require either preemployment, or termination, or periodic examinaton occasional short-term exposures. The Recommendation with respect to vari ances undoubtedly has many merits, of any employee who has been examined but is considered administratively im in accordance with the standard within practical. where asbestos hazards are present. the past year. Accordingly, after consideration of the However, labeling, rather than warning signs, has proved to be a point of con troversy. Both NIOSH and the Advisory Committee on Asbestos Dust recom mended labels for asbestos products and One question which has been raised goes to whether the employer or the em ployee should be allowed to choose the examining physician. The standard gives the option to the employer. Since whole record of the proceeding, and pursuant to sections 6 (b) and (c) and 8(c) of the Williams-Steiger Occupa tional Safety and Health Act of 1970 (84 containers, and these recommendations some employers already have a medical Stat. 1593, 1596, 1599; 29 UH.C. 655, became very controversial in the course examination program in operation, and, 657), 29 CFR 1910.4, and to Secretary of of the proceeding. Many counterpro also, have medical departments with Labor's Order No. 12-71 (36 FJt. 8754), proposals have been made as to the lan guage of the warning as well as to the products to be subject to the labeling requirements. Employers, in general, strongly contend that (1) finished prod some expertise in the diagnosis of abestos-related diseases, it seems more reasonable to permit them to utilize the present programs and expertise, than to permit an employee to choose a private Part 1910 of Title 29 of the Code of Fed eral Regulations is amended as set forth below. .
