TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with hot surfaces.
Water spray, foam, powder, carbon dioxide .
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


 •INHALATION Drowsiness. Confusion. Unconsciousness.
Closed system and ventilation.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness. Pain.
Protective gloves.
Rinse and then wash skin with water and soap.
 •EYES Redness. Pain.
Safety goggles
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION

Do NOT induce vomiting.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: self-contained breathing apparatus. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment.
Separated from strong acids. Cool. Keep in a well-ventilated room. Store in an area without drain or sewer access.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.

CHEMICAL DANGERS:
The substance decomposes on contact with hot surfaces or flames producing hydrogen chloride , hydrogen fluoride and phosgene . Reacts with strong acids .

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation .

INHALATION RISK:
On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is mildly irritating to the eyes . The substance may cause effects on the central nervous system and cardiovascular system , resulting in lowering of consciousness and cardiac disorders . Suffocation.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is harmful to aquatic organisms. This substance may be hazardous in the environment; special attention should be given to its impact on the ozone layer.
N O T E S
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
