Polychlorinated Biphenyls


PCB’s are a class of industrial chemical that contain 209 individual compounds. PCB’s made in the United States were marketed under the trade name Aroclor and were identified by a four digit numbering code in which the first two digits indicate that the parent molecule is a biphenyl and, for the 1200 series Aroclors, the last two digits indicate the chlorine content by weight. For example, Aroclor 1254 has 54% chlorine.

PCB’s are generally clear, colorless to light yellow, viscous liquids or solids with a mild hydrocarbon odor. They have a low vapor pressure, and therefore low volatility.

Chronic (long term) exposure to PCB’s by inhalation in humans has been reported to result in respiratory tract irritation and gastrointestinal effects including anorexia, weight loss, nausea, vomiting, abdominal pain and mild liver effects. Effects on the skin and eyes include chloracne, skin rashes, and eye irritation.

Worker Chemical Hazard Assessment

• Inhalation:

PCB’s low volatility makes the release of potentially significant levels of airborne vapor extremely unlikely, so that the most probable inhalation exposure would be to PCB-containing dusts generated during excavation. However, the low soil concentrations indicate that very high dust levels would need to be generated for the current OSHA PEL’s to be exceeded. Based on the low concentrations of PCB’s in the soil, inhalation exposure potential is expected to be minimal.

• Direct Contact and Ingestion:


Direct skin contact with soils and ingestion of soils is possible if proper hygiene practices are not followed at the work site. The use of protective gloves and covering exposed skin, and thorough hand, face and arm washing prior to eating, drinking or smoking will minimize skin absorption and ingestion potentials.



I was QC'ing a summary for a safety plan submittal ..... :rolleyes:

The format is messed up, but it's a proof for some sort of dashboard decal I was drawing.
 
Sometimes when I reflect back on all the beer I drink I feel ashamed.
Then I look into the glass and think about the workers in the brewery
and all of their hopes and dreams. If I didn't drink this beer,
they might be out of work and their dreams would be shattered.
Then I say to myself, "It is better that I drink this beer and let their dreams come true
than be selfish and worry about my liver."
