Types of Hazard/ Exposure
|
Acute Hazards/ Symptoms
|
Prevention
|
First Aid/
Fire Fighting
|
|
FIRE
|
Extremely flammable.
Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking.
|
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with
powder,
carbon dioxide.
|
|
Explosion
|
Gas/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
Use non-sparking handtools.
|
In case of fire: keep cylinder cool by spraying with water.
Combat fire from a sheltered position.
|
|
|
|

Important Data
|
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 as TWA; A1 (confirmed human carcinogen); (ACGIH 2004).
MAK:
Carcinogen category: 1;
(DFG 2004).
OSHA PEL: 1910.1017 TWA 1 ppm C 5 ppm 15-minute
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Ca N.D. See: IDLH INDEX
|
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
is irritating to
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 andperipheral blood vessels, and tissue and bones of the fingers.
This substance is carcinogenic to humans.

N O T E S
|
Depending on the degree of exposure, periodic medical examination is suggested.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
