NOISE
* Hearing loss is a natural part of aging
* It can not be repaired
* It can be made worse by excessive exposure to noise
ASBESTOS
* The higher the noise, the less time is required to do harm
* Still used in certain parts of the plant (encapsulated,
e.g.: in Plasticizer Building)
* Very short fibers can lodge in the lung, causing long-term problems, including "asbestosis," the most common sickness
* Other illnesses are possible, including cancers of the digestive system
VAB.0001032959

LEAK AND SPILL CONTROL
GENERAL
* Keep all materials contained!
* Use the correct container for each material
* Keep the container closed
VCM
* Keep the container properly labeled
* No VCM leak is acceptable
* Leak repair always has the top priority
LEAD
* Indicators include: icing, hissing noises, condensation, odor, and measurements with instruments
* Keep dusting to a minimum
* Avoid unecessary crushing of empty lead bags. 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. It seriously decreases respirator effectiveness
* Medical certification required for all personnel who may have to use respirators
* No exceptions allowed for users
AIR-LINE RESPIRATORS
* Breathing air supplied to mask via a hoseline
* Good for any chemical, but used mostly with VCM (up to 1,000 ppm)
* Used for a variety of routine jobs associated with VCM
- Hooking/unhooking VCM railcars - Changing VCM filters - Opening, depressuring, or isolating any VCM
equipment - Working in the VCM compressor shed - All work, including maintenance, where VCM is
present above 1 ppm
SCOTT AIR-PAKS
* Self-contained respirator * Good for any chemical, but used mostly with VCM * Used for emergencies
* 'Must be used for protection against VCM
- Above 1,000 ppm - In unknown concentrations

BULLARD HOOD-TYPE RESPIRATOR
* A special type of air-line respirator
* Used for Dust Collector entry
3M A1RHAT (DUST, MIST, AND FUME) * A battery-operated, air-purifying respirator
4 4

* Keep assigned Airhat clean
* Check airflows daily. Change filters if needed to keep good airflow
* Turn in for thorough cleaning and repair each month
* Report any problems immediately. Do not use a bad Airhat
3M AIRHAT (HIGH EFFICIENCY)
* 2 Airhats are being modified to become "high efficiency"
* For use when handling asbestos, per new OSHA standard
HEARING PROTECTION

VENTILATION Keep ail vent tans and hoods running - each serves an important purpose Report inoperative or detective equipment Follow department procedures in Compound
- Check Magnahelic guages - Keep Building Ventilation System hoppers cleaned out
- Check airtlows with the department velometer
VAB.0001032965
EMERGENCIES
* Must be prepared to handle them
* Know what you are expected to do ahead of time * Leave endangered areas when alerted unless your job is to stay and help handle the emergency * Hre-plan what you will do under different circumstances * Remember that everyone must be accounted for as quickly as possible during any emergency
VAB.0001032966
DOSIMETRY
GENERAL
* We measure routine exposures to VCMf lead, and total particulates (dusts). 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.

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

III. REVIEW OF RESPIRATORS - Continued
Cm Scott Sllng-Pak Ila (15-Min. Unit)
1. Same as Scott Pressure Pak Ila, except:
a. 15-min. air supply - bottles are smaller versions of 2.2 bottle.
b. Lighter. c. Quicker to use. d. Simplified strapping.
2. Offers same protection as Scott Pressure Pak II. 3. Used in short jobs in VCM concentrations of 1000 ppm+ or unknown. 4. Selectable between "Demand" mode and "Pressure Demand" mode. Must
be used in "Pressure Demand" mode in VCM.
D. Air-Line Respirators
1 Fresh Air System Review 2. Used in plant most commonly for VCM atmospheres of no more than
1000 ppm. 3. Two facepiece sizes. 4. Two makes - you have a choice! Use what works best for your face. 5. Disconnect respirator supply tube from hose connector prior to
connecting to air supply hose to blow line clear. 6. Facepiece fit is very important, although constant flow will tend
to overcome minor leaks. 7. Adjust flow control valve to give slight excess of supplied air
during rapid inhalation.
E. 3M Airhat
1. Battery operated. 2. Removes dusts from air. 3. Used in lead and asbestos work. 4. Offers head and eye protection. 5. Offers no protection against gases! 6. Does not supply oxygen!

IV. PRACTICAL EXERCISE
A. Air-Line Respirators
1. Proper fitting of facepiece, including seal check. 2. Proper connection to air supply. 3. Correct adjustment of flow control valve. (Deep, fast breath does
not pull respirator against face--negative pressure condition).
