TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, alcohol-resistant foam, carbon dioxide.
EXPLOSION Above 22°C explosive vapour/air mixtures may be formed.
Above 22°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. Headache. Nausea.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN Dry skin. Redness.
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
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
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.
Fireproof. Separated from oxidants. Cool.

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

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes slowly on contact with air or moisture producing acetic acid and n-butanol. Reacts violently with strong oxidants causing fire and explosion hazard. Attacks many plastics and resins.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 150 ppm; 713 mg/m3 (ACGIH 1991-1992).
MAK as STEL: 200 ppm; 950 mg/m3; (ACGIH 1991-1992). (199?)


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.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the respiratory tract. Exposure far above OEL could cause lowering of consciousness.

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