Fourth t Examine work practices to identify those causing dust production and eliminate,modify,or explore alternate ways . - ' t , i Fifth; Initiate engineering controls that will have a sustained effectj such as, substitution of materials, new methods, ventilation control,iso lation, enclosure and dust collection. ` Sixth; An educational program is necessary to explain program directives, changes of work practices, techniques,and medical requirements. Seventh; Medical programs are now required. Each asbestos worker must be medically and environmentally monitored. Record keeping and availability of the records to both the worker,his physician and to OSHA or NIOSH are embodied in the requirement. ' ASBESTOS HAZARD CONTROL - ' G EN ER AL C U A N C IR G '. 1 P R A C T IC ES I S A S I * P L K ,E C O f m i C A L , AMD P R A C T IC A L APPIOAOH TO CONTKOJ.

Use a portable industrial vacuum cleaner for pick-up of asbestos waste and dust at the work site. 3* Use plastic impregnated paper coveralls and dust respirators for dusty operations of a n incidental nature. The coveralls are throw-away and eliminate processing and cleaning, - L . Use down-draft ventilated portable work tables for precutting and assembly at asbestos materials at remote locations,mobile situations or inside ships. 5, Precut all block insulation in shops under ventilated condition and then deliver it to location. ' " . ` Package pre-cut. block Insulation in plastic and add water to contain dust,, maintain integrity of gores,identification,and ease of handling* 7, Reduce airborne asbestos dust 50 to 4>0 % by prewetting the materials before handling. P, Nix asbestos cement (15#) at remote locations under ventilated conditions. Nix small batches in plastic bags, - 7. Spread plastic or canvas drop cloths at work site to contain and facilitate clean-up. . 10, Conduct modular assembly of asbestos materials on piping prior to Installation 11. Consider disposable forms of respiratory protection for onetime or intermittent use situations. (U.S. Bureau of mines Approved.) ` 12. Substitute non-asbestos products whenever suitable,acceptable and feasible. . ' 13. Use enclosures to limit the spread of dust from unit operations. 14* Seperate clean-up areas for workmen. 15. Limit exposure of other trades in the vicinity of asbestos work. l. Develop asbestos work stations^. either portable or stationary , to control dust production* . ' . * 17. Develop suitable storage and storing areas-. Some practices.that produce high asbestos dust' levels : and SHOULD be prohibited . 1. Do not clean up fallen asbrstos debris with brooms or brushes. ( 2. Do not allow debris to'be thrown from staging or from one deck to another. 3. Do not shake coveralls or drop cloths. * 4. Do not remove respirators before asbestos dust ladenclothing* 5. Do not clean dusty clothes with an air' gun. 4. Do not vent asbestos dust picked up by ventilation into adjoining work areas,or ships compartments. . , 7. Do npt wear respirators covered with asbestos dust. ' 8. Do not wear street clothes to handle asbestos materials or .under known dusty conditions* 9. Do not use asbestos for welders pads. lO.
