In a fire, PVC can form hydrogen chloride fumes; the chlorine serves to scavenge free radicals, making PVC-coated wires fire retardant. While hydrogen chloride fumes can also pose a health hazard in their own right, it dissolves in moisture and breaks down onto surfaces, particularly in areas where the air is cool enough to breathe, so would ...
The effect was studied in PVC pipe makers, who breathed in vinyl chloride and developed rare liver cancers, said Ruth Lunn, who studies carcinogens at the National Institute of Environmental ...
The hepatotoxicity of vinyl chloride has long been established since the 1930s when the PVC industry was just in its early stages. In the very first study about the dangers of vinyl chloride, published by Patty in 1930, it was disclosed that exposure of test animals to just a single short-term high dose of vinyl chloride caused liver damage.

The film explains the dangers of what could happen if this substance goes near a flame considering it is highly flammable and will release toxic fumes when burned. Many of the PVC plant workers have been diagnosed with cancer because of the toxic fumes that this vinyl contains.
CPVC sprinkler pipe inside a firestop mock-up. Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling.
What are the warning signs and symptoms of toxic fume exposure? According to experts, the most common signal that a toxic fume event is occurring is a bad smell coming from the plane’s air vents.
Plenum cable is jacketed with a fire-retardant plastic jacket of either a low-smoke polyvinyl chloride (PVC) or a fluorinated ethylene polymer . Polyolefin formulations, specifically based on polyethylene compounding had been developed by at least two companies in the early to mid-1990s; however, these were never commercialized, and development ...
In October, passengers reported fumes filled the cabin on an American Airlines flight from Miami to Barbados, according to the Associated Press. OSHA proposed $6,837 in penalties following its ...
