The current time-weighted average concentrations of 5 fibers will be permitted until July 1, 1976. A ceiling limit of 10 fibers per cc will apply for both S and 2 fibers/cc TWA standards. Monitoring Schedule: 1. Within 6 months after effective date, July 7, 1972, both employee's exposure and the environment or work place dust concentrations must be determined and recorded (Time-weighted average and ceiling levels must be determined by prescribed methods). 2. Afterward, at least every 6 months. 3. The results of air sampling must be maintained and available for inspection for at least 3 years. Warning Signs: 1. In work areas wherever concentration of asbestos dust may exceed TLV or TWA. 2. On container for new, used and waste asbestos materials. 3. The legend or text to be used is expressed. Records on Dust: 1. Environmental concentrations of asbestos dust maintained for inspection. 2. Personnel exposure data determined by procedures established in regulations while employee carries out all dusty operations. 1. lS-0000750 002170 (Records on Dust - Continued) 3. These continuous data stored for at least 3 years after the last exposure. Medical Examinations for Potentially Exposed Employees: 1. X-rays, pulmonary test within 30 days of reporting on-job handling asbestos. 2. X-rays, pulmonary test within 30 days of termination. 3. Annual examinations by 1-31-73 for all employees exposed to asbestos after December 1971. Records on Medical Matters: 1. Examination record available to employers, employees' physicians and Government physician on request. 2. Medical examination record must be maintained 20 years. 2. 18-0000751 002171 STANDARD FOR EXPOSURE TO ASBESTOS DUST The new standard provides the following: A. Acceptable concentrations. As of July 1, 1976, time-weighted average concentrations of asbestos fibers longer than 5 micrometers will not be allowed to exceed 2 fibers per cubic centimeter of air. The current time-weighted average concentrations of 5 fibers will be permitted until July 1, 1976. A ceiling limit of 10 fibers per cc will apply for both S and 2 fibers/cc TWA standards. B. Methods of compliance. Feasible technological controls and appropriate work practices are required as the primary means of compliance. Rotation of employees to reduce their exposures is allowed only in "exceptional circumstances." Personal protective equipment, such as respirators, cannot be relied upon, in large part because such devices are so uncomfortable as to be burdensome except for short periods. The standard includes these other compliance requirements: Hand tools that may produce or release asbestos fibers in excess of the limits must be provided with local exhaust ventilation systems. Insofar as practicable, asbestos must be handled, mixed, applied, removed, cut, scored or otherwise worked in a wet state to reduce fiber emissions unless this would diminish the usefulness of the product. No asbestos cement, mortar, coating, grout, plaster or similar material containing asbestos can be removed from shipping bags or other containers without being either wetted, enclosed or ventilated. Where respirators are permitted, they must be selected from among the types approved by the Bureau of Mines or NIOSH. Extensive details are given on types of respirators and conditions for their use. No employee may be assigned to a task requiring a respirator if a physician determines it would affect his job functioning or his health. 3. GO2172 18-0000752 The employer must prov^e and require the use of special protective clothing, change rooms, and two separate lockers for the employees' street and work clothes. The employer also must exercise care in laundering and other handling of contaminated clothing. External work area surfaces must be kept free of excessive accumulations of asbestos fibers. Waste must be collected in sealed, impermeable bags or other such containers. Restrict the number of potentially exposed employees by isolating the work area. Use barricades and signs to limit unauthorized entrance. Where respirators may be used, they are subjected to the following limitation: 1. Reusable or single use air-purifying respirators may be used for exposures up to 10 times the TWA or TLV. 2. Powered air-puTifying respirators may be used for exposures from 10 to 100 times the TWA or TLV. 3. Type "C" supplied-air respirator must be used above 100 times the TWA or TLV and must be used for specific operations. These are spraying, demolition and/or removal of asbestos materials. Where conditions of exposure exceed the ceiling level prescribed in Sec. 1910.93a, (b)(3), 10 fibers/cc., the employer shall provide special clothing, whole body clothing, head covers, gloves and foot coverings. Under these exposures, in regular work locations, the employer must furnish double locker and shower facilities for employees. The responsibility for clothing and respirator cleaning and maintenance will also be that of the employer. Monitoring Employers must establish monitoring systems to make certain every employee's exposure to asbestos fibers is below the prescribed limits. If the limits are exceeded, the employer must undertake a compliance program. There fore, the standard also requires monitoring at intervals no longer than 6 months and gives employees or their repre sentatives the opportunity to observe the monitoring and to have access to such records. 4. 18-0000753 C02173 D. Warning signs Caution signs are to be displayed in areas where asbestos concentrations may exceed the exposure limits. Caution labels must be affixed to all raw materials, mixtures, scrap, waste, debris and other products containing loose asbestos fibers, or to their containers. However, no label is required where asbestos has been modified by a bonding agent, coating, binder or other means that would prevent release of TLV concentrations into the breathing air. Caution signs and labels for asbestos work areas and asbestos material in containers should conform to the specification in Section 1910.145(d)(4). Descriptions of signs and labels suitable to meet these requirements are given here. The warning sign shall be a 20Mxl4" vertical format. The word "Caution" shall be in yellow on a black background of 3 1/4" x 13 3/8" upper panel. The legend (text) shall be in black letters on a yellow background in the lower panel of 15 1/2" x 13 3/8" size. An example: CAUTION ASBESTOS Dust Hazard Avoid Breathing Dust. Wear Assigned Protective Equipment. Do Not Remain in Area Unless Your Work Requires It. Breathing Asbestos Dust May Be Hazardous to Your Health Label Specifications These iabels shall be easily legible at reasonable distances. CAUTION Contains Asbestos Fibers. Avoid Breathing Dust. Breathing Asbestos Dust May Cause Serious Bodily Harm. 18-0000754 5. 002174 E. Record keeping of environmental exposures Employers must maintain records of personal and environ mental monitoring, keep them for at least 3 years after last exposure, and make them available upon request to OSHA or NIOSH. Every current and former employee is to be given opportunity for reasonable access to any records indicating their current and past exposure to asbestos dust. Any employee found to have been exposed at any time to airborne concentrations in excess of the limits (TWA or ceiling) must be notified in writing no later than 5 days after the finding, and informed as to correc tive action being taken. F. Medical examinations. The employer must provide, or make available at his cost, medical examinations for all asbestos handlers. Within 30 days of an employee's first employment in a job involving asbestos exposure, the employer must provide a comprehensive medical examination, including a chest X-ray and pulmonary tests. By January 31, 1973, and at least annually thereafter, employer shall provide or make available comprehensive medical examinations to employees in asbestos exposure areas. A similar examination is to be provided within 30 days before or after termination of employment. G. Medical records Employers whose employees have been examined under the standard must maintain complete records of these examina tions and retain them for at least 20 years. The contents of the records are to be made available for inspection and copying to the Assistant Secretary of Labor for OSHA, the Director of NIOSH, authorized physicians and medical consul tants of either agency, and upon request of an employee or former employee, to his physician. Any physician who conducts an examination under the standard must furnish the employer all medical information required by the standard, and any other medical findings related to occupational exposure to asbestos fibers. 6. G02175 18-0000755 H. Housekeeping Use dropcloths under all delagging or rip-off. Completely saturate the insulation or lagging by inserting manifolded injection heads with numerous holes so that water can seep into the material. Use water fog or fine spray to soak insulation and then direct spray on cutting tools during delagging. If needed, use plastic sheeting to form a tent around the job to prevent dust dispersal. Do not permit the insulation to dry while handling or before bagging. If wet waste falls, drips or splashes, remove it by squeegee or push brush. If material dries it should be re-wet before handling. It is necessary to clean up dry materials with a vacuum sweeper having a suitable filter collector. Part of the housekeeping involves the proper practices in handling soiled work clothes. Dust covered clothes can dislodge fibers into the breathing zone. Contaminated clothing must be segregated into labeled and sealed plastic bags or containers. The employee should continue to wear a dust respirator throughout the undressing and until the soiled clothing is sealed in containers. If the clothing is sent out for cleaning or laundrying, it is the employer's responsibility to explain the nature of the hazard to the laundryman. These clothes or their sealed container must be properly labeled. All waste and loose asbestos materials should be stored in impenetrable containers and suitably labeled. Waste asbestos should be wetted, moved in disposable bags or containers firmly closed, with labels, and buried on land or disposed of at sea with permission; I. Employee education Because asbestos is used in many insulation materials, fireproofing, packing, coatings and caulking compounds, these uses are of great concern throughout the Humble and Enjay companies. For as many places as feasible, it is recommended that the companies in all their operations discontinue using material containing asbestos. Asbestosfree materials are available and many substitutes come at 7. 002176 18-0000756 no higher cost. Today's goal is to eliminate exposure of personnel to asbestos when installing new materials. All Company Engineering Standards should remove those materials that contain asbestos and provide substitutes. If special jobs require its use, because asbestos-free material is not satisfactory, then safe practices for a special application should be established for each job. Safe practices for bringing in and using asbestos materials in a company facility should be approved only by the facility's top management. Special effort will be required by each person to break old habits. The practices of replacing insulating materials in kind is a typical case or example. The remaining area of concern, though less important, is the reuse of existing pipe and block insulation and asbestos materials on hand. The safe practices for those jobs where asbestos material is approved for use should include: 1. Pre-wet all mortar while in "airfree" plastic bags. 2. Cut blocks, pipe forms, head sections and transite boards only in the shop on saws with suitable exhaust ventilation. 3. Pre-dip in water the cut pipe covering, blocks, boards, gaskets, etc., and transfer to the job site in sealed plastic bags while damp. 4. Use drop cloths under all asbestos applications. 5. Clean the asbestos work areas daily with water fog, spray or an industrial-type vacuum cleaner. 6. Limit the worst dusty jobs to shortest possible time and to the least number of employees in area. 7. Restrict number of employees in dusty area and then use only best respiratory protection. 8. Use easily washed coveralls or disposable garments for high dust exposure. Resin sealed paper coveralls are cheaper and available for single use. 8. 002177 18-0000757 9. ContTol of employees' exposure by rotation of the employee is not an acceptable means under OSHA regulations. Engineering methods for dust control and substitution of nonasbestos materials must be exhausted first. 10. Although respiratory equipment may be used, it cannot be the principal method used to eliminate exposure. Engineering methods and substitute means also should be used fully. 11. Employees who are not involved should be restricted from the dust exposure area by a barrier with warning markings. 12. Where engineering controls are not feasible, respira tors may be used, subject to the following limitations: a. For exposures up to 10 times the TWA or TLV, reusable or single use air-purifying respirators are accep table. b. From 10 - 100 times the TWA or TLV, powered airpurifying respirators may be used. c. Above 100 times the TWA or TLV, type "C" suppliedair respirator must be used. d. The spraying, demolition, ripping-off, delagging or asbestos material removal requires protection of a type "C" supplied-air respirator only, regard less of the dust concentration. Also, special clothing and bath facilities are required for these jobs. e. Identify all material purchased with as much as 1% or more asbestos content. J.

Methods of compliance. It has been pointed out by many persons, that pro tection against asbestos fibers is best obtained by controlling the generation of fibers first, and secondly.'by controlling the dispersion of released fibers into the ambient air of the workplaces.

The recom sure. It docs not make sense to require employers to provide medical examina tions if they cannot know and use the results of the examinations. For these reasons the standard provides that em ployers may have a restricted access to some medical information.

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 Issues discussed above are believed to be the major ones.
