Powder, water spray, foam, carbon dioxide.
EXPLOSION


EXPOSURE
AVOID ALL CONTACT!

 •INHALATION Cough.
Local exhaust or breathing protection.
Fresh air, rest.
 •SKIN Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance is a strong reducing agent and reacts with oxidants. The substance decomposes on heating producing irritating fumes .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Inhalable aerosol and vapor) 5 mg/m3 as TWA; (ACGIH 2005).
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, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
