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.
EXPOSURE
STRICT HYGIENE!

•INHALATION Dizziness. Dullness. Headache. Abdominal cramps.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves. Protective clothing.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Pain. Blurred vision.
Face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION
Do not eat, drink, or smoke during work.

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:

Solubility in water, g/100 ml at 20°C: 0.574
Vapour pressure, kPa at 20°C: 133.3
Relative vapour density (air = 1): 2.22
Flash point:
-50°C c.c.
Auto-ignition temperature: 519°C
Explosive limits, vol% in air: 3.6-14.8
Octanol/water partition coefficient as log Pow: 1.54

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. Card has been partly updated in April 2005: see sections Occupational Exposure Limits, Emergency Response. Card has been partly updated in October 2006: see section Occupational Exposure Limits.
