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 fiber utilizing asbestos fiber or materials containing asbestos ok The standard is divided into eight major categories 1 1 1910.93a Permissible Exposure Sets the maximum in the workplace allowable air asbestos fiber concentration 2 1910.93a Methods of Compliance Recommends procedures to meet the exposure limits 3 1910.93a Personal Protective Equipment Specifies types of personal protective equipment and defines the circumstances under which they are required 4 1910.93a Method of Measurement 1910.93a Monitoring Specifies the monitoring procedures to be used if your workplaces meet the allowable exposure to determine limits 5 1910.93a Caution Signs and Labels States when caution wording to be used signs and labels are required and the 6 1910.93a Housekeeping Specifies results to be obtained methods of waste disposal | from housekeeping and the PRODUCED JM - 83 x 7. 1910.93a Recordkeeping Sets type and duration of requirements for employee monitoring recordkeeping notification of monitoring Sets results 9 1910.93a Medical Examinations Details the requirements for medical examinations Specific Comments 1 Exposure Levels 1910.932) It is the employer's responsibility to assure that exposure of employees to airborne concentrations of asbestos fibers does not exceed the limits prescribed by the Standard The OSHA asbestos asbestos fiber in standard maximum permissible the workplace air are limitosf a Eight hour time weighted average 1 2 At present 5 Effective July fibers per cubic centimeter 1 1976 2 fibers per cubic centimeter b Ceiling concentration 1 2 At present 10 fibers per cubic centimeter Effective July 1 1976 no change In both cases the standard refers to fibers 5 micrometers longer than 2. Methods of Compliance 1910.95a ] Engineering Methods Engineering ventilation controls and dust such as isolation enclosure exhaust 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 be provided with local exhaust systems PRODUCED JM - 83 Wet Methods When practicable asbestos products shall be handled in a wet state sufficient to prevent the emission of dust to the atmosphere This usefulness of the The applicability procedure is not required where the product might be diminished be wetting of wet methods is limited In most situations engineering controls as noted above are more applicable Personal Protective Equipment and Clothing 1910.93a ] Respiratory Protection Respiratory protection is required whenever the airborne concentrations of asbestos fiber exceed either the time weighted average limit or permissible ceiling The type of respirator to be used is determined by fiber concentration in the workplace permissible permissible concentration concentration concentration the a Fiber 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 require the use of similar whole body foot coverings limit the employer shall provide and special clothing such as coveralls or clothing head coverings gloves and 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 PRODUCED JM- 83 Methods of Measurement 1910.93a] Monitoring 1910.95a 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 all workplaces where asbestos fibers are released shall _ be be monitored to determine exposure repeated at six month intervals levels Monitoring must 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 representatives shall be given a reasonable opportunity to observe any required monitoring and shall have access to the monitoring records Any employee found to have airborne concentrations of been exposed at asbestos fibers any time to in excess of the prescribed limits shall be notified in writing of the exposure as soon as the finding practicable but not later than five days of Caution Signs and Labels 1910.93a Caution signs shall be displayed at each workplace where where asbestos fiber concentrations exceed permissible exposure exposure exposure exposure 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 Housekeeping 1910.93a ] 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 the recommendations on proper housekeeping procedures see Housekeeping section under general recommendations PRODUCED JM - 83 7 Recordkeeping 1910.93a] 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 Medical Examinations 1910.93a Preplacement annual and termination medical examinations must be provided or made available by the employer for any employee engaged in occupations exposed to airborne concentrations of asbestos fibers These medical records must be kept for 20 years and are available to the employee's physician PRODUCED JM - 83 GENERAL RECOMMENDATIONS Exhaust and Dust Collection Systems The ISHA Asbestos Standard requires that exhaust and dust collection systems be designed and maintained in accordance with American National Standard the Design and Operation of Local Fundamentals Governing Exhaust Systems ANSI 1971 Another authoritative reference is Industrial Ventilation A Manual of Practice Prepared by Committee on Industrial Ventilation American Conference of Governmental Hygienists P. O. Box 453 Lansing Michigan 48902 Recommended Industrial The . 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 of the Agency may fire or explosion authorize the use hazard the Administrator of a high energy wet collector For small intermittent production and fabrication operations major dust collection systems of the high volume low velocity type design described in the references above may not be necessary Instead as their systems exhaust of the low air source volume high velocity type utilizing a high efficiency vacuum cleaner could be suitable For design information on these systems refer to pages 21 through 45 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 te baghouse be checked daily A scheduled maintenance program that includes bag replacement should be prepared and followed American National Standards 14 Broadway New York NY 10018 Institute PRODUCED JM -83 < . . cn _ Wherever possible operations involving 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 plant because airborne dust created by lack of housekeeping has the potential for harm to your employee The OSHA asbestos standard in any place of employment of asbestos fiber if with excessive concentration stipulates that all external surfaces shall be maintained free of accumulations their dispersion there would be an It is recommended that surface Portable vacuum cleaning units filtration and disposable dust cleaning be done by vacuum should be equipped with internal bags Single or multi stationary vacuum cleaning systems designed for use with asbestos containing dusts are available from at least two manufacturers* Vacuum cleaning stations can be added to existing dust collection systems as shown on sketches in Appendix B. If circumstances require floor sweeping with loose material being swept should be treated dust suppressant brooms then the with water or other 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 and 45 PRODUCEDPRODUCED JM - 83 Personal Hygiene In the use of asbestos for the processing of products unless good procedures are followed containing dust conditions can result Employees must be aware that excessive inhalation of asbestos dust may be be made to eliminate to dust injurious to health Every effort should dust conditions and avoid unnecessary exposure Good personal 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 work their families and those with whom they Avoid cigarette smoking Wash thoroughly before eating . Shower after work - Wear proper protective clothing including head covering when the situation warrants Change to from work work clothes upon arrival at work clothes at conclusion of work and change If work clothing is taken home carry wash separately from other clothing clothing Use a washing machine in a bag and Never shake dusty - Use respirators when required fit properly Be sure that respirators It makes good sense to have a dust free workplace It to the health of all involved Dust conditions can be by the simple application of good practices and common the workplace is important controlled sense in PRODUCED JM - 83 11 RECOMMENDED WORK PRACTICES SHOP AND FIELD FABRICATION OF ASBESTOS SHEET PRODUCTS SPECIFIC RECOMMENDATIONS - COMMENTS Prior to handling of sheet materials excess dust should be removed from the surface of the sheets to prevent dispersion of asbestos fiber into the workplace Fabricating machinery should be equipped with control systems Refer to standards noted on designs shown on pages 12 through 45 suitable dust page 8 and to typical 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 PRODUCED JM - 83 12 SHOP FIXED TOOLS PRODUCED JM - 83 PRESENT EQUIPMENT -DESIGN MODIFICATIONS 13 RADIAL ARM SAW ia bhi AA iy. ye. a SAW POST i! oN | 4a 0 SAW PULLED BACK 7 THRU MATERIAL MATERIAL a a ae BEING CUT 1 Dust escapes from top side of material as saw breaks through top surface - some goes to saw post area some goes around top guard and out towards operator 2 Dust escapes from bottom surface as saw breaks through and goes below table top Recommended engineered dust control system " 5 DIA sft nis hy SAW POST I . 4-} on ADD NEW TAKEOFF | eo _ y EXISTING HOOD NN , , . te CLEAR ABOVE WORK - POSS: 6WITH " Soy ~ = == - ao -- RUBBER SKIRT ON FLG SIDES OF OPENING WIDE SLOT 3 SIDES NONE IN FRONT AIRVOLUME = 1500 M.
