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.
Water spray. Alcohol-resistant foam. Dry powder. Carbon dioxide.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


 •INHALATION
Ventilation.
Fresh air, rest.
 •SKIN Dry skin.
Protective gloves.
Rinse skin with plenty of water or shower.
 •EYES
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Diarrhoea.
Do not eat, drink, or smoke during work.
Rinse mouth.
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.
Separated from strong oxidants.

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.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: mist 10 mg/m³ as TWA (ACGIH 2005).
MAK: 50 mg/m³ (Inhalable fraction)
Peak limitation category: I(2) Pregnancy risk group: C
(DFG 2006).
OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
NIOSH REL: See Appendix D
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:


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:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
