TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 45C explosive vapour/air mixtures may be formed.
Above 45C 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 Redness.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion

Rinse mouth.
SPILLAGE DISPOSAL PACKAGING & LABELLING
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. Personal protection: filter respirator for organic gases and vapours.

sec-HEXYL ACETATE ICSC: 1335
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 50 ppm as TWA; (ACGIH 2004).
MAK: IIb (not established but data is available) (DFG 2004).
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, the skin and the respiratory tract. Exposure at high levels may result in unconsciousness.

PHYSICAL PROPERTIES
Boiling point: 146C
Melting point: -64C
Relative density (water = 1): 0.86
Solubility in water: none
Vapour pressure, kPa at 20C: 0.4
Relative vapour density (air = 1): 5.0
Relative density of the vapour/air-mixture at 20C (air = 1): 1.01
Flash point: 45C c.c.
Explosive limits, vol% in air: 0.9-5.7
