The Act has the stated objective of assuring every American worker a safe and healthy workplace. On December 7, 1971 the Secretary of Labor issued am emergency temporary standard for exposure to asbestos dust. As required by the Act/ a permanent standard for asbestos exposure was promulgated six months later on June 7, 1972. The present OSHA Asbestos Standard, discussed in this booklet, became effective on July 7, 1972. The work practices on the following pages have been prepared by the Standards and Technical Committee of the Asbestos Information Association/North America. They are intended as general guidance for safe and clean workplace conditions in keeping with the spirit and intent of the OSHA Standard for Occupational Exposure to Asbestos Dust. These practices have been developed through careful study and consultation and are recommended as good procedure. It is recognized that manufacturing conditions vary. Implementation of the practices contained herein cannot be considered as a guarantee of OSHA compliance. Where there may be a question of compliance, OSHA personnel should be consulted. Thorough understanding of the OSHA Asbestos Standard is important to management of any company utilizing asbestos in its manufacturing or processing operations. The proposed revised standard contained in the Federal Register of Thursday, October 9, 1975, (Vol. 40, No. 197, Part II) will not be a subject of discussion in this manual since it is a proposal without an effective date. When the final revisions are promulgated, this manual will be up-dated. ST 0395960 PRODUCTS AND OPERATIONS Types of asbestos sheet products covered by these work practices are: .

Operations to which these work practices may apply are: Handling and warehousing Drilling General Housekeeping, including waste disposal Shaping Sawing Sanding ST 039596 c3 SUMMARY OF THE REQUIREMENTS OF THE OSHA ASBESTOS STANDARD (1910.93a) General Comments After extensive public hearings, OSHA published a "Standard for Exposure to Asbestos Dust" in the Federal Register, Volume 37, No. 110 dated Wednesday, June 7, 1972. A copy of the complete standard is included at the back of this booklet. It applies to any manufacturing, fabricating or handling process or operation utilizing asbestos fiber or materials containing asbestos fiber. The standard is divided into eight major categories: 1. 1910.93a(b) Permissible Exposure Sets the maximum allowable asbestos fiber concentration in the workplace air. 2. 1910.93a(c) Methods of Compliance Recommends procedures to meet the exposure limits. 3. 1910.93a(d) Personal Protective Equipment Specifies types of personal protective equipment and defines the circumstances under which they are required. 4. 1910.93a(e) Method of Measurement l910.93a(t) Monitoring- Specifies the monitoring procedures to be used to determine if your workplaces meet the allowable exposure limits. 5. 1910.93a(g) Caution Signs and Labels States when caution signs and labels are required, and the wording to be used. 6. 1910.93a(h) Housekeeping Specifies results to be obtained from housekeeping and the methods of waste disposal. ST 0395962 4 7. 1910.93a(i) Recordkeeping Sets type and duration of monitoring recordkeeping. Sets requirements for employee notification of monitoring results. 8. 1910.93a(j) Medical Examinations Details the requirements for.medical examinations./ Specific Comments 1. Exposure Levels [1910.93a(b)] It-isTthe~.employer ^"responsibility to assure'that exposure of employees,to airborne concentrations of asbestos fibersi does,not exceed the limite prescribed by the Standard; The OSHA asbestos standard rnaxii un permissible limits of asbestos fiber in the workplace air are: a. Eight hour time weighted average: (1) At present: 5 fibers per cubic centimeter. (2) Effective July 1, 1976: 2 fibers per cubic centimeter. b. Ceiling concentration: (1) At present: 10 fibers per cubic centimeter. (2) Effective July 1, 1976: (no change). In both cases, the standard refers to fibers longer than 5 micrometers. 2. Methods of Compliance [1910.93a(c)] Engineering Methods Engineering controls such as isolation, enclosure, exhaust ventilation and dust collection shall be used to meet the prescribed exposure levels. All"hand operated and power operated, tools which may produce^ airborne asbestos fibers~in excess of permissible exposure? levels shall*7 1be2 * p* *r*ovided with , local_;.exhaust systems J ST 0395963 5 Wet Methods When practicable, asbestos products shall be handled in a wet state sufficient to prevent the emission of dust to the atmosphere. This procedure is not required where the usefulness of the product might be diminished be wetting. The applicability of wet methods is limited. In most situations, engineering controls as noted above are more applicable. 3. Personal Protective Equipment and Clothing fl910.93a(d)] Respiratory Protection .,, .. Respiratory protection is-required'whenever the airborne concentrations of asbestos fiber exceed either the permissible time weighted average limit or permissible ceiling concentration. The type of respirator to be used is determined by the fiber concentration in the workplace. a. Fi^er concentrations up to, but not exceeding 10 times the allowable limit: Air purifying respirator - reuseable or single use. b. Fiber concentrations up to, but not exceeding 100 times the allowable limit: Powered air purifying respirator. c. Fiber concentrations exceeding 100 times the.allowable limit: Type "C" supplied air respirator. Protective Clothing Whenever the airborne fiber concentrations exceed the prescribed ceiling limit the employer shall provide and J require the use of special ^clothing, Such as coveralls or? similar whole body clothing, head coverings, gloves,.and * foot coverings .-3 Whenever the airborne fiber concentrations exceed either the permissible time weight average concentration or permissible ceiling concentration the employer shall provide change rooms for his employees. The change rooms shall be equipped with two separate lockers or containers for each employee so separated or isolated as to prevent contamination of the employee's street clothes from his work clothes. 196S6C0 IS 6 4. Methods of Measurement [1910.93a(e)J Monitoring [1910.93a(f)] All monitoring shall be done by the membrane filter method at 400-500 x (magnification) (4 millimeter objective) with phase contrast illumination. The standard requires that within six months of its effective date, ail: workplaces where'rasbestos' fibers. are released shall^ be monitored to deterralne-jexposure ^levels Monitoring must ' be repeated at six month intervals if' the''fiber concentrations are above permissible limits. If fiber concentrations are below permissible limits, monitoring should be repeated at reasonable intervals at the employer's discretion. Affected"employees'or their.Lrepresehtatives shell 1 be - given* a reasonable opportunity to observe any required monitoring^1 and shall" have access to jthe.monitoring records? Any employee found to have been exposed at any time to airborne concentrations of asbestos fibers in excess of the prescribed limits shall be notified in writing of the exposure as soon as practicable but not later than five days of the finding. 5. Caution Signs and Labels [1910.93a(g)] Caution signs shall be displayed at each workplace where asbestos fiber concentrations exceed permissible exposure limits. Caution labels shall be applied to all materials and products which during any reasonably foreseeable use might release concentrations of asbestos fibers in excess of permissible exposure limits. 6. Housekeeping [1910.93a(h)] All external surfaces, machinery and equipment shall be maintained free of asbestos fiber accumulations that might, if dispersed, create asbestos fiber concentrations above permissible exposure limits. For recommendations on proper housekeeping procedures, see the "Housekeeping" section under general recommendations. ST 0395965 7. Recordkeeping [1910.93a(i)] Every employer shall maintain records of any personal or environmental monitoring required by the standard. Records shall be maintained for a period of at least three years. 8. Medical Examinations [1910.53a(j)J Preplacement, annual, and termination medical examinations i must be provided or made available by the employer for any 7 employee "...engaged in occupations exposed to airborne & concentrations of asbestos fibers." These medical records i must; be kept for 20 years and are available to the employee's J physician.^ ST 0395966 1r . \` 1; ' ~ - . '* GENERAL RECOMMENDATIONS ;,, j'V S Exhaust and Dust.Collection Systems The OSHA Asbestos Standard requires that exhaust and dust collection systems be designed and maintained In accordance with American National Standard*, "Fundamentals Governing the Design and Operation of lk>cal Exhaust Systems", ANSI 29.2-1971. Another authoritative reference,is: Industrial Ventilation, A Manual of Recommended Practice 'Cv' ' Prepared 'by: . ' -U'4- Committee on Industrial Ventilation American Conference Of Governmental Industrial Hygienists ..:.i . P. 0. Box 453 Lansing, Michigan .48902 V The U. S. Environmental Protection Agency requires that the air cleaning device used with asbestos fiber dust collection ! systems be a fabric filter collector. When the use of fabric filters creates a fire ot explosion hazard, the Administrator of the Agency may authorize the use of a high energy, wet collector. | For small and intermittent production and fabrication operations major dust collection systems of the high volume, low velpcity type design described in the references above may not be necessary. Instead, systems of the low volume, high velocity type utilizing as their exhaust air source a high, efficiency vacuum cleaner could be suitable. For design information on these systems refer to pages 21 through 45. /* ,*j " - , All exhaust and dust collection systems should be inspected periodically for proper functioning. For continuous operations it is recommended that the system operation and the interior of the baghouse be checked daily. A scheduled maintenance program ! that includes bag replacement should be prepared and followed. ! `American National Standards Institute 1430 Broadway - New York, NY 10018 . I>.

't, 9 Wherever possible, operations involving asbestos-containing materials should be isolated from other work areas by partitions, curtains or other means. If central exhaust systems are utilized, the work areas should be maintained under a slight negative pressure. Housekeeping Housekeeping is an essential part of any manufacturing operation. It is even more essential in an asbestos-using plant because airborne dust created by lack of housekeeping has the potential for harm to your enployee. The OSHA asbestos standard stipulates that "all external surfaces in any place of employment shall be maintained free of accumulations of asbestos fiber if, with their dispersion, there would be an excessive concentration". It is recommended that surface cleaning be done by vacuum. Portable vacuum cleaning units should be equipped with internal filtration and disposable dust bags. Single or multi-hose stationary vacuum cleaning systems designed for use with asbestos containing dusts are available from at least two manufacturers. * Vacuum deeming stations cam be added to existing dust collection.systems as shown on sketches in Appendix B. If circumstances require floor sweeping with brooms, then the loose material being swept should be treated with water or other dust suppressamt. The OSHA standard requires that asbestos waste which when handled or transported could generate airborne fibers in excess of the allowable exposure limits, be disposed of in sealed bags or closed containers. Mentioned on pages 44 amd 45. ST 0395968 f 10 Personal Hygiene _; In the use of asbestos for the processing of asbestos-containing products unless good procedures are followed dust conditions can result. Employees must be aware that excessive.inhalation of asbestos dust may be injurious to health.p Every effort should be made to eliminate dust conditions and avoid unnecessary exposure tO dUSt. . 15 ' i" ' Good person^ hygiene practices are important in every working situation. When working with asbestos, workers are urged to observe the following personal hygiene practices for their own health protection, their families' and^ those with whom they worki . Avoid cigarette smoking .? 1k . Wash thoroughly before eating . Shower after work . Wear proper protective clothing including head covering when the situation warrants c . Change to work clothes upon arrival at work and change from work clothes at conclusion of work r. . If work clothing is taken home, carry in a bag and wash separately from other clothing. Never shake dusty clothing. Use a washing,machine. ;= . Use respirators when required. Be sure that respirators fit properly. "V' It makes good sense to have a dust free workplace.. It is important to the health of all involved. Dust conditions can be controlled by the simple application Of good practices and common sense in the workplace.

Fabricating machinery should be equipped with suitable dust control systems. Refer to standards noted on page 8 and to typical designs shown on pages 12 through 45. All dust control systems which discharge exhaust air to atmosphere must be equipped with fabric filter collection devices (requirement of the Federal Environmental Protection Agency "National Emission Standards for Hazardous Air Pollutants Asbestos"). Wet fabricating methods can be a suitable alternative to dust control systems utilizing exhaust ventilation. After fabricating and before shipping all excess dust and chips should be removed from the surface of the sheet to prevent dust contamination of the fabricator's workplace and his customer's workplace. All dust and waste must be disposed of in accordance with paragraph "Housekeeping" on Page 9. Dust from the dust collection devices must be disposed of in sealed containers. Scrap disposal, since it is not friable and disposal does not generate asbestos fiber concentrations above permissible levels, need not follow the requirement for sealed and labeled containers.

There are 2 types of sanders used in sanding asbestos sheets to get smooth surfaces. They are as follows: BELT TYPE SANDERS These are rough type belt sanders using a continuous belt of abrasive against the material in scratching action which generates loose dust. The amount of dust in dependent upon grade of, abrasive (fine to-coarse) on belt, belt speed and pressure on sander against surface being sanded. The dust is mainly at the back of the sander but some is emitted along the sides of the belt. ST 0395997- BELT TYPE SANDER VIBRATORY TYPE SANDERS These vibratory type sanders are a finishing type sander which use a strip of sand paper below a cushion pad with the ends fastened in various manners.

Hillier cc All Divisions J. Goldfield File X24-9014 BOOSTER FAN - VACUUM CLEANING BASIC DESIGN CRITERIA Summary Described below is a method of installing a vacuum system utilizing less costly components and existing dust collection and waste disposal equipment to effect a saving in initial investment of the order of 30% to 40% over commercial systems, plus reduced power, maintenance and handling costs. Description General The system consists of standard vacuum hoses and tools connected to a piping system (see dwg. 30383-4). Location of outlets should be governed by area of activity and the reach of standard 25 ft. hoses. The air is exhausted by an industrial fan and discharged into a nearby dust main, which carries the dusty air to an existing cloth dust collector. This can effect a considerable saving in piping, as well as eliminating the need for a separate dust collector to meet air pollution standards. Selection of Pickups A basic system is sized to cover am area with up to 20 stations where a maximum of two vacuum stations are expected to be in use at one time. (400 cfm) Additional stations should be handled by adding a parallel system for each two stations required, to maintain carrying velocities. The usual maximum for one installation would be six stations simultaneous with a 900 cfm exhauster and approximately 60 stations total. Fan The fan should be selected per the attached specification. The volume is selected as follows: ST 0396009 D. E. Hillier Page 2 August 29, 1972 a) Basic system (2 stations in use): 400 cfm. b) Two parallel systems (4 stations in use): 600 cfm. c) Three parallel systems (6 stations in use): 900 cfm. The total pressure is selected as follows: a) Maximum length of longest branch approx. 150'-200': use 40" T.P. Water Gauge. b) Maximum length of longest branch approx. 250'-300': use 60" T.P. Water Gauge. Typical fan selections are: Buffalo Forge, Type "RE", extra heavy wheel. New York Blower, "Pressure Blower", steel wheel. Type P, Series Lamson, Cast Iron Centrifugal Exhauster. Dust Trap In highly abrasive situations, such as transite and cement board plants, a dust trap should be installed preceeding the fan. (See dwg. standard) This trap is sized to handle up to 900 cfm (the largest single system recommended). Tools Piping Typical tools and piping are called out on the attached bill of material sheet. The quantity is normally what would be required by each system to allow convenient location to each operator, but not enough to encourage abuse by the use of more than two outlets simultaneously. The usual quantity is three or four sets of hoses and tools per basic system. Suppliers are Hoffman, Spencer, Lamson, etc. Attachments 1. Typical Vacuum System - #30383-4. 2.
