EDUCATION MEETING OF JULY 21, 1970 SAFETY REQUIREMENTS FOR WORKING WITH ASBESTOS-CONTAINING MATERIALS ON CONSTRUCTION JOB SITES IN ILLINOIS Beg inrting August T, 1970., the Department of Labor, Division of Sarety Inspection and Education intends to require that the, following safety practices be observed on Illinois constructionjob sites. These are rules which have been adopted by New York. " SPRAYING ASBESTOS - CONTAINING MATERIAL - ` . 1. Before the start of spraying operations all floor areas shall be swept broom clean. Before the application of asbestos- containing material commencesthe floor of the area shall be cleared of ail .objects, materia] and equipment other than that . employed in the application of the asbestos-containing insula- : tion on ali objects, material, etc. shall be covered with plastic or plastic-cccted tarpaulins in a manner that precludes the sub sequent dispersal of asbestos particulates. 2. TI:a. entire floor, or the part of the floor to be insulated, . shall be enclosed with plastic or plastic-coated tarpaulins In. a manner which shall preclude the escape of asbestos-containing material from, the enclosure. All interior open areas, such as elevator shafts, stairwells, etc. shall be enclosed in a manner . which shall prevent the escape of asbestos-containing material . from the working area. "Stack effect" of the shafts, stairwells, etc. shall be considered in providing proper enclosures. An enclosure wilt be considered satisfactory only if visible . . .. . . insulating moterial cannot escape from the enclosure. 3. Wet asbestos-containing material which has fallen to the floor shall be immediately swept up and placed in a container having walls, bottom, and a tight cover strong enough to resist tearing or breaking under normal handling conditions and clearly marked as containing asbestos waste. The contents of the aforementioned . containers shall not be transferred to another container, but the container shall be piaced directly upon a vehicle for disposal at an approved site. 70071506 4 P "ay *r.g * r* 111!noi s Department of Labor 'Tic,*'*c* s . k. All floors will be vacuumed shortly after drying. The vacuum cleaner shall contain a strong, single-service, disposable inner bag tightly sealed.

Enclosures shall not be dismantled until the area has been thoroughly vacuumed after completion of spraying cleanup. 7. All areas used for opening bags containing asbestos insu lating material and/or charging of hoppers shall be enclosed in such a manner that asbestos-containing insulating material shall not be permitted to escape from the immediate area in which such activity takes place. 8. Signs shall be posted outside enclosures warning persons of the hazard of entering the enclosure without appropriate mask and other apparel. - 9. All persons involved in the spraying of asbestos at the site must be furnished with Bureau of Hines approved respirators for pneumoconionic-producting dust and must be furnished with suitable coveralls which will be left at the site and thereby preclude the > removal of asbestos from the site. No person shall be permitted in an area in which asbestos spraying or handling has taken place until final vacuuming referred to in paragraph numbered "5" . herein, unless such person is furnished with and wears a 3ureau of Mines approved respirator for pneumoconionic-producting dust and coveralls of the type described herein. Facilities shall be provided and dispersal of asbestos-containing material from the construction site on the clothing or other appurtenances of persons leaving the area. ' 10. Any plenum or other structures coated with asbestos-containing insulation which is intended for use in the circulation of air in the building must be thoroughly cleaned of all debr s and waste insulation. All applied asbestos-containing insulation within a plenum or duct must be coated with a sealant which preculdes exposure of the asbestos-containing material to the circulation air. - 9- 20071507
