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.
Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state.
Use non-sparking handtools.
|
In case of fire: keep cylinder cool by spraying with water.

|
Fresh air, rest.
Refer for medical attention.
|
|
•Skin
|
ON CONTACT WITH LIQUID: FROSTBITE.
|

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.
Chemical Dangers:
The substance decomposes
on heating
or
on burning
producing
toxic gases
(
hydrogen chloride
- see ICSC 0163,
phosgene
- see ICSC 0007).
Occupational Exposure Limits:
TLV: 100 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: skin absorption (H);
Carcinogen category: 3B;
(DFG 2004).
EU OEL: 268 mg/m3 1200 ppm as TWA (EU 2006).
OSHA PEL: TWA 1000 ppm (2600 mg/m3)
NIOSH REL: Handle with caution in the workplace. See Appendix C (Chloroethanes)
NIOSH IDLH: 3800 ppm 10%LEL See: 75003
|
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 mildly irritating to
the eyes
,
the skin
and
the respiratory tract
.
Rapid evaporation of the liquid may cause frostbite.
The substance may cause effects on the
central nervous system
.
Exposure far above the OEL may result in
unconsciousness
,
cardiac dysrhythmia
and
death
.
Effects of Long-Term or Repeated Exposure:

Environmental
Data
|
The substance is harmful to aquatic organisms.
|
|
N O T E S
|
Use of alcoholic beverages enhances the harmful effect.
Rinse contaminated clothes (fire hazard) with plenty of water.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
