TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION Above 32°C explosive vapour/air mixtures may be formed.
Above 32°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


•INHALATION Cough. Dizziness. Drowsiness. Headache. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
•SKIN Dry skin. Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES Redness. Pain.
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.
Rinse mouth. Give one or two glasses of water to drink.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place.
Fireproof. Separated from strong oxidants.

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

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
Reacts with oxidants causing fire and explosion hazard. Attacks many plastics.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA; 100 ppm as STEL; (ACGIH 2004).
EU OEL: 50 ppm, 270 mg/m3 as TWA; 100 ppm, 540 mg/m3 as STEL (EU 2000).
OSHA PEL: TWA 125 ppm (650 mg/m3)
NIOSH REL: TWA 125 ppm (650 mg/m3)
NIOSH IDLH: 1000 ppm See: 626380


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

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. Exposure at high levels may result in lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
