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 41°C explosive vapour/air mixtures may be formed.	Above 41°C use a closed system, ventilation, and explosion-proof electrical equipment.

EXPOSURE		PREVENT GENERATION OF MISTS!
•INHALATION	Cough. Sore throat. Unconsciousness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
•SKIN	Dry skin. Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES	Redness. Pain.	Safety goggles.	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. Rest. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Ventilation. 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. Do NOT wash away into sewer. (Extra personal protection: filter respirator for organic gases and vapours).

Fireproof if in building. Separated from strong oxidants. Cool.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID.

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

CHEMICAL DANGERS:
Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 25 ppm; 104 mg/m³ (as TWA); 40 ppm; 167 mg/m³ (as STEL) (skin) (ACGIH 1997).
MAK: 25 ppm; 100 mg/m³; H (1996).
OSHA PEL: TWA 25 ppm (100 mg/m³) skin
NIOSH REL: TWA 25 ppm (100 mg/m³) ST 40 ppm (165 mg/m³) skin
NIOSH IDLH: 400 ppm

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

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, the skin and the respiratory tract. Exposure could cause lowering of consciousness.

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