Do near the ventilation hood, if possible * Use vacuum cleaing methods to clean with. Use of compressed air with lead is illegal! ASBESTOS * Before handling asbestos - Rope off the area - Get Tyvek suit, rubber gloves, and a "high efficiency" Airhat - Bring plastic bags, open top drums, and plastic sheeting to the site * During the work - Keep dusting to a minimum - Keep material wet at all times - Catch falling pieces of material with plastic sheeting - Make as few cuts as possible - Do not drop material, if possible - Place all scraps in plastic bags as work proceeds * After the work - Put all collection bags and sheets in drums - Put Tyvek suits and gloves in drums - If outside, flush area with water - If inside, wet-wipe - Close drums and apply labels VAB.0001032961 PROTECTIVE CLOTHING AND EQUIPMENT RESPIRATORS FACIAL HAIR POLICY * For all personnel who can be assigned emergency duties * No facial hair permitted in area of respirator seal.

Other exposures, including those involving unusual jobs, are measured when the need arises. * Noise measurement is also done, but on a less frequent basis, and using outside help and special equipment EQUIPMENT REAL "MINIMONITOR" BADGES * Used to monitor VCM exposure * Wear the badges when assigned - Membrane facing out - Do not cover them with outer garments or protective clothing - Do not lay them about, on tables, desks, etc. * AIR PUMPS AND CASSETTE FILTERS * Used to measure exposures to lead and dusts * Wear at all times during work period - Wear filter on collar, pointed down - Report pump problems immediately DOSIMETRY CARD * Fill out card and turn in at guard house at end of work period * Note respirator use * Note anything you did, or was near, which you think might have caused an overexposure RESULTS * Examined carefully by supervision and management. No overexposure is considered acceptable to them. * You will be notified of any overexposure as soon as the results are available VCM - Usually within 3 - 5 days Lead and Dust - Usually within 2 1/2 - 3 1/2 weeks A VAB.0001032967 MEDICAL TESTING * Done to see if any medically significant problems related to VCMf Lead, or other environmental agents exist * Repeat testing, including blood-lead tests, will be done, as needed * Take advantage of the program. Participate, * Advise your supervisor of any problems you have with the service * You will be given a copy of your exam results when the doctor has finished his work VAB.0001032968 PERSONAL HYGIENE * There is no good substitute for good, consistent personal hygiene * Avoid contact with materials unless necessary to do a job * Always wash hands, face, arms before eating, drinking, smoking, or applying cosmetics. This is especially so with lead, and is a good practice for all materials * Do not take food, drinks, cosmetics, or tobacco products into lead areas * Remove contaminated, protective clothing before entering clean areas, particulary when dealing with lead. % VAB.0001032969  RESPIRATOR TRAINING h CLASS OUTLINE November 1, 1985 I. INTRODUCTION A. Purpose of Class B. Schedule of Class Events II. GENERAL A. Company Res 1. Maintain an on-going program to protect employees from respirable chemical hazards via a respiratory protection program. 2. Ensure that the program Is carried out. 3. Conduct effective training in the use and care of respirators. B. Employee Responsibilities 1 Use appropriate respirator whenever a respirable chemical hazard Is present. 2. Inspect respirators before each use: e.g, elastomer parts, face pieces, cleanliness, completeness (nothing missing), hoses, etc. 3. Fit-check respirators to test seal effectiveness. 4. Turn in respirators for cleaning and maintenance as specified. 5. Report respirator problems promptly to Safety. III. REVIEW OF RESPIRATORS A. Scott Pressure Pak Ila (Older 30-Mln. Unit) 1. Self-contained breathing apparatus (SCBA). 2. Uses breathing quality air from supply bottle. 3. Used In YdM concentrations of 1000 ppm+ or unknown. 4. A "30-Minute" supply bottle. 5. Must be used only by trained personnel. 6. Selectable between "Demand" mode and "Pressure Demand" mode. 7. Must be used In "Pressure Demand" mode In VCM. 8. Provides the best face fit (best "Protection Factor"). B. Scott Pressure Pak 2.2 (Newer 30-Mln. Unit) r Same device as "Pressure Pak III", .except for improvements, including: l' 1. Fewer harness straps. Use of ^quick-opening belt. 2. In "Pressure Demand" mode at all times. 3. Improved weight distribution via backpack carrier. 4. ImpfoVed vision. 5.
