Vinyl chloride
Properties of vinyl chloride is described below
PHYSICAL STATE; APPEARANCE:
COLOURLESS COMPRESSED LIQUEFIED GAS , WITH CHARACTERISTIC ODOUR.
PHYSICAL DANGERS:
The gas is heavier than air, and may travel along the ground;
distant ignition possible. Vinyl chloride monomer vapours are
uninhibited and may form polymers in vents or flame arresters of storage
tanks, resulting in blockage of vents.
CHEMICAL DANGERS:
The substance can under specific circumstances form peroxides,
initiating explosive polymerization. The substance will polymerize
readily due to heating and under the influence of air, light, and on
contact with a catalyst, strong oxidizing agents and metals such as
copper and aluminium, with fire or explosion hazard. The substance
decomposes on burning producing toxic and corrosive fumes ( hydrogen
chloride , phosgene ). Attacks iron and steel in the presence of
moisture.
OCCUPATIONAL EXPOSURE LIMITS:
TLV: 1 ppm; A1 (ACGIH 1999).
OSHA PEL: 1910.1017 TWA 1 ppm C 5 ppm
15-minute
NIOSH REL: CA
NIOSH IDLH: Potential occupational carcinogen No data
ROUTES OF EXPOSURE:
The substance can be
absorbed into the body by inhalation.
INHALATION RISK:
A harmful concentration of this gas in the air will be reached very
quickly on loss of containment.
EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes. The liquid may cause frostbite.
The substance may cause effects on the central nervous system . Exposure
could cause lowering of consciousness. Medical observation is indicated.
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver, spleen, blood and
peripheral blood vessels, and tissue and bones of the fingers. This
substance is carcinogenic to humans.
