TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks and NO smoking.
Carbon dioxide, dry powder, foam.
EXPLOSION Above 15.5C explosive vapour/air mixtures may be formed.
Above 15.5C 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.
Ventilation, local exhaust or breathing protection.
Fresh air, rest.
Skin Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. Pain.
Safety spectacles, 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.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Do NOT wash away into sewer. 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.

tert-BUTYL ACETATE ICSC: 1445
IMPORTANT DATA
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 acids, strong bases, strong oxidants including nitrates causing fire and explosion hazard. Attacks plastic.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 200 ppm as TWA; (ACGIH 2002).
MAK: 20 ppm; 96 mg/m; Peak limitation category: II(4); Pregnancy risk group: D; (DFG 2002).
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 vapour is irritating to the respiratory tract. The substance is mildly irritating to the eyes and the skin. Exposure far above the OEL could cause lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
PHYSICAL PROPERTIES
Boiling point: 97.8C
Relative density (water = 1): 0.86
Solubility in water: poor
Vapour pressure, kPa at 25C: 6.3
Relative vapour density (air = 1) : 4
Relative density of the vapour/air-mixture at 20C (air = 1): 1.19
Flash point: 15.5C c.c.
Explosive limits, vol% in air: 1.5-7.3
Octanol/water partition coefficient as log Pow: 1.76
