FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA: Carbon dioxide, foam, dry chemical powder or water spray
FIRE FIGHTING: Firefighters should wear NIOSH/MSHA approved self-contained breathing apparatus
and full fire-fighting turn out gear. Dike area to prevent runoff and contamination of water sources.
Dispose of fire control water later.
HAZARDOUS DECOMPOSITION PRODUCTS: Decomposes on heating emitting soot, smoke,
decomposition products and carbon monoxide. Fire Fighting Procedures Fire fighters to wear
self-contained breathing apparatus (SCBA) if exposed to products of decomposition. Full protective
clothing is also recommended

ACCIDENTAL RELEASE MEASURES
Clear area of all unprotected personnel. Do not allow traffic to pass over contaminated area. Contain using
sand and soil prevent runoff into drains and waterways. Do not smoke, drink or eat during clean up
operations. Use absorbent (soil, sand, vermiculite or other inert material)
Collect and seal in properly labeled drums for disposal and sweep the area. If the area is still damp, repeat
procedure.
NOTE: Paraquat is bound strongly to clay-based materials and thus effectively deactivated. To eliminate
any traces of unabsorbed material, dose the spill area with sodium hypochlorite or bleach solution, allow to
stand for about 30 mins then hose down with water as a final clean up. Bury sweepings and damaged
containers under 50cm of soil in a selected dump remote from dams and watercourses. Refer to local
government Authority for information on a suitable site. If contamination of crops or waterways has
occurred advise Emergency Services or Department of Agriculture. If contamination of sewers or
