TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.

PHYSICAL STATE; APPEARANCE:
 COLOURLESS LIQUID.

PHYSICAL DANGERS:
 The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:
 The substance decomposes on heating and on burning producing toxic and corrosive fumes including hydrogen chloride and phosgene (see ICSC # 0163 and ICSC # 0007). Reacts violently with strong oxidants and metal powders causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
 TLV not established.


ROUTES OF EXPOSURE:

INHALATION RISK:
 A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C on spraying and dispersing however much faster.

EFFECTS OF SHORT-TERM EXPOSURE:

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
Boiling point: 69°C
Melting point: -131°C
Relative density (water = 1): 0.9
Solubility in water: none
Relative vapour density (air = 1): 3.2
Flash point: -10°C
Explosive limits, vol% in air: 2.0-8.8
ENVIRONMENTAL
DATA

N O T E S
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
