AMBER VISCOUS LIQUID

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including hydrogen bromide or bromine.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
