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, dry powder, carbon dioxide.
EXPLOSION Above 49°C explosive vapour/air mixtures may be formed.
Above 49°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

•INHALATION Cough. Sore throat. Drowsiness. Dullness. Headache.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN Redness. Dry skin.
Protective gloves.
Rinse skin with plenty of water or shower.
•EYES Redness.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Nausea. Vomiting. Diarrhoea. Dizziness. Drowsiness.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts with oxidants , bases and reducing agents .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA (ACGIH 2000).
OSHA PEL†: none
NIOSH REL: TWA 50 ppm (235 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX


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

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is mildly irritating to the eyes and the skin . The vapour is irritating to 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.
