PVC & Vinyl Chloride health hazards: this article (part 2) discusses US EPA-provided information on health effects of exposure to vinyl-chloride (PVC - polyvinyl chloride) and hPVC and gives references to more scholarly information sources.
To improve clarity and provide public information we include here information from several US government sources including the US EPA and the US ATSDR, Department of health and Human Services, Agency for Toxic substances and Disease Registry. Our page top photo shows vinyl siding damaged by use of a barbecue grill placed too close to the building exterior wa
ll of a home in Port Jervis, NY - a potential fire hazard. (The grill had been removed when we took this picture). Owners noticed a "plastic odor" when they were cooking outdoors!

Vinyl & Vinyl Chloride Possible Health Hazard Information Provided Here - Dioxin (potent carcinogen) & HCL
The following information was obtained from the US EPA, to which we have made a few [additions of content from other sources and occasional edits for clarity].
Most vinyl chloride is used to make polyvinyl chloride (PVC) plastic and vinyl products. Acute (short-term) exposure to high levels of vinyl chloride in air has resulted in central nervous system effects (CNS), such as dizziness, drowsiness, and headaches in humans.
Chronic (long-term) exposure to vinyl chloride through inhalation and oral exposure in humans has resulted in liver damage. Cancer is a major concern from exposure to vinyl chloride via inhalation, as vinyl chloride exposure has been shown to increase the risk of a rare form of liver cancer in humans. EPA has classified vinyl chloride as a Group A, human carcinogen.
ACGIH TLV--American Conference of Governmental and Industrial Hygienists' threshold limit value expressed as a time-weighted average; the concentration of a substance to which most workers can be exposed without adverse effects.
LC50 (Lethal Concentration50)--A calculated concentration of a chemical in air to which exposure for a specific length of time is expected to cause death in 50% of a defined experimental animal population.
OSHA PEL--Occupational Safety and Health Administration's permissible exposure limit expressed as a time-weighted average: the concentration of a substance to which most workers can be exposed without adverse effect averaged over a normal 8-h workday or a 40-h workweek.
OSHA PEL ceiling value--OSHA's permissible exposure limit ceiling value; the concentration of a substance that should not be exceeded at any time.
Conversion Factors [for table on health data about Inhalation of Vinyl Chloride Gas]
The health and regulatory values cited in this factsheet were obtained in December 1999.
The following is quoted from the US ATSDR.
Plastic odors and the detection & source-diagnosis of many common odor sources observed some installations of vinyl exterior building siding or in other plastic or vinyl building products such as windows and trim are discussed at VINYL SIDING or WINDOW PLASTIC ODORS.
For a more broad approach to diagnosing building odor sources, see ODORS, Smells, Gases in Buildings-Diagnosis & Cure and see our ODOR DIAGNOSIS CHECKLIST, PROCEDURE
