This legislation is far-reaching. It coven millions of employees and nearly every em ployer. To asst in assuring compliance with them laws, the asbestos<emem industry is disseminating information regarding the hazards of expo sure to airborne asbestos. One means of reducing hazards of exposure a to reduce the exposure through good wort practices. Good wort practices is what this booklet is about. The reoomroendadors that appear on the following pops were developed through study and field testing. They are designed to achieve safer and more health ful job site conditions when wotting with asbestoement (A/C) sheet products. Since field conditions will vary, adherence to these wort practices will not necessarily guarantee compliance with national, state or local regulations. Questions relating to compliance should be directed to appropriate regulatory agenda. ' The Asbestos Informabon Assodaboo/North America believes this booklet will help engineers, superintendents, contractors, foremen and crews to understand procedures for the safer handling and fabrication of A/C sheet products. This booklet supersedes AIA/NA recommended wort practices for field fabrication of asbestos sheet products previously distributed in 1975. January 25, 1980 Asbestos and Health Airborne asbestos fiber has been intientified as a possible health hazard Inhalation of these fibers in excessive quantities may cause pulmon ary disease. But like the automobile, electricity and x-rays, there are non-harmful ways to use potentially harmful things. Asbestos-cement IA/Q sheet products contain 15% to 40% asbestos. The asbestos fibers are not free, but "locked-in" the cement binder, like reinforcing rods in concrete. The distinction between Tree' and "bound* asbestos is extremely important First of all it determines the proba bility of fiber release, which in turn, directly relates to the probability of risk. Mote importantly, it explains dearly and simply why A/C sheet is a proper use of asbestos. The present state of scientific learning on asbestos shows that mini mizing exposure to airborne asbestos dust reduces the hazards of asbestos-related disease. During the use and handling of A/C sheet, the only time that fibers may be released in significant quantities from a health standpoint, is during fabrication operations when sufficient mechanical energy is applied to the product to literally "tear* the fibers from the cement binder. One means of reduong airborne fiber generation is through good work practices. 3 Summary of OSHA Asbestos Standard Under the current OSHA standard for occupational exposures to asbestos, it is the employer's responsibility to assure that exposure of employees to airborne concentrations of asbestos fibers does not ex ceed the following "permissible exposure levels'': a. Eight-hour time-weighted average: Two fibers, longer than 5 micrometers, per cubic centimeter. b. Ceiling concentrations: Ten fibers, longer than 5 micrometers, per cubic centimeter. In October 1975, OSHA proposed a revision to the current standard which would reduce the eight-hour time-weighted average exposure to 0.5 fibers per cubic centimeter of air and ceiling concentrations to 5.0 fibers per cubic centimeter. OSHA specifically excluded the con struction industry from coverage within that proposal. In their notice, OSHA stated that a separate standard would be proposed to cover workers who handle asbestos-containing products in the construction industry. The work practices recommended in this booklet are based on data for *'peak dust concentrations''representing short time periods of maxi mum exposure. Fieldfabricating operations involving the cutting of A/Csheet are normally infrequent and ofshort duration. Using these recommended work practices, which will maintain fiber levels below OSHA allowable ceiling concentrations, it Is improbable that field personnel would be exposed in a typical working day to levels ex ceeding the current OSHA eight-hour time-weighted average per missible exposure limit For full text of OSHA standard for occupational exposure to as bestos dust (29 CFR 1910.1001) refer to A ppendix B. Products and Operations The following work practices are applicable to flat and corrugated A/C sheet products: Operations to which these work practices apply include: Shipping, Receiving and Handling Cutting Drilling Hole Cutting and Cutouts Housekeeping and Waste Disposal Equipment used with these work practices is available from the sources shown in the equipment list (page 17). 772S5 Shipping, Receiving and Handling A/C sheet is shipped from the factory with clean surfaces. jencriUy in pallet loads, using shipping methods acceptable to the producer and the customer. All unloading operauons should be carefully performed to avoid sheet damage. Pallet loads are normally unloaded by fort tract. Small shipments may require manual unloading. 6 772SG Cutting -- Flat Sheets Circular Saw Circular un for eutui| flat them should be used onty whets equipped with the tpeafic dim collection hoods pictured above.

It is even more essential when airborne dust created by the Jock of good housekeeping has the potential for harm to employees and others. EQUIPMENT: All external surfaces of equipment should be main tained free of dust accumulations that might, if dispersed, create as bestos fiber concentrations above pennissible exposure limits. WASTE DISPOSAL: Asbestoacement dust chips and cuttings from the field operations described in this booklet must be collected in a manner that will not contribute airborne asbestos dust to the atmos phere. Loose material should never be dry swept When vacuum equipment is available, h should be used. Water or other dust sup pressants should be applied in those circumstances where sweeping is unavoidable. DO NOT BLOW WASTE MATERIAL WITH COM PRESSED AIR. No visible emissions to the atmosphere are permitted from the collection, processing, packaging, transporting or deposition of any asbestcs-containing material. Wastes must be collected and disposed in accordance with the requirements of the US Environmental Protection Agency. For full text of EPA waste disposal requirements (40 CFR, Chapter 1, Part 61) refer to Appendix C 15 77295 Vacuum Geaner Specifications (Values shovm bdow are minimum recommended) Circular Saw -- Flat tod Combated Sheet Cuttmt Vacuum (lift): Airflow: 59" W.G.
