SAFE HANDLING INFORMATION
4.1 Storage / Transport
Store in a well ventilated and dry area. Keep containers well closed. Protect from exposure to air or light - store
under nitrogen. Keep away from sources of ignition. Vapours are heavier than air and are explosive. Keep
away from - alkaline cyanide solutions (may initiate exothermic condensation reactions), strong bases (may
iniate exothermic condensation reaction), strong reducing or oxidising agents and performic acid (violent
reaction).

Disposal
If recycling is not possible, eliminate in accordance with locally valid waste disposal regulations (notify
authorities if required).
4.4 FIRE AND EXPLOSION HAZARD
Fire / Explosion
Combustible liquid. Hazardous products of thermal decomposition include carbon dioxide and carbon
monoxide.
Extinguishing Media
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. In case of fire use
water, dry powder, foam or carbon dioxide type extinguishers.
5 OTHER INFORMATION
Other Information
Stable under normal temperatures and pressures. May oxidize in air to benzoic acid. May undergo exothermic
polymerisation on contact with strong bases, reducing agents and alkaline cyanide solutions. Ecological
information: water contaminant, biodegrades fairly readily (low potential risk).
