TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT GENERATION OF MISTS!
•INHALATION	Cough.	Ventilation.	Fresh air, rest.
•SKIN	Dry skin.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
•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	Nausea. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Rest. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place.

PHYSICAL STATE; APPEARANCE:
HYGROSCOPIC, VISCOUS COLOURLESS LIQUID.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating producing corrosive fumes of acrolein. Reacts with strong oxidants causing fire and explosion hazard. Reacts violently with acetic anhydrides in the presence of a catalyst.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 mg/m³ mist (ACGIH 1995-1996).
OSHA PEL: TWA 15 mg/m³ (total) TWA 5 mg/m³ (resp)
NIOSH REL: See Appendix D
NIOSH IDLH: No data

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its mist.

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Vapour pressure, Pa at 20°C: <0.1

Relative vapour density (air = 1): 3.17
Flash point: 177°C o.c.
Auto-ignition temperature: 370°C
Explosive limits, vol% in air: 0.9-?
