TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
AFFF, alcohol-resistant foam, dry powder, carbon dioxide.
EXPLOSION Above 22C explosive vapour/air mixtures may be formed.
Above 22C 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. Sore throat. Dizziness. Headache.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
 •EYES Redness. Pain.
Safety goggles, 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 Nausea.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Ventilation. Remove all ignition sources. Collect leaking and spilled liquid in sealable metal or glass containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: filter respirator for organic gases and vapours.)
Fireproof. Separated from strong oxidants, strong bases, strong acids. Cool.

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

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
Reacts with strong oxidants , strong acids , strong bases causing fire and explosion hazard. Attacks many plastics and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 150 ppm as TWA; 200 ppm as STEL; (ACGIH 2003).
MAK: 100 ppm, 480 mg/m;
Peak limitation category: I(2); Pregnancy risk group: C;
(DFG 2003).
OSHA PEL: TWA 150 ppm (710 mg/m3)
NIOSH REL: TWA 150 ppm (710 mg/m3) ST 200 ppm (950 mg/m3)
NIOSH IDLH: 1700 ppm 10%LEL See: 123864


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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the respiratory tract . The substance may cause effects on the central nervous system . Exposure far above the OEL could cause lowering of consciousness.

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