SECTION 4 – FIRE AND EXPLOSION HAZARDS

 

 

Flash Point (Method):               None                Explosive Limits: Lower            None    Upper              None   

Flammable Limits:                     None                Auto Ignition Temperature:        None

Extinguishing Media:                 Does not burn.

 

Special Fire Fighting Procedures and Hazards:  Self contained positive pressure breathing apparatus.

 

Unusual Fire & Explosion Hazards:       Can react violently on contact with water producing heat and gas.

 

SECTION 5 – REACTIVITY INFORMATION

 

 

Stable:    X                               Hazardous Polymerization:                    Does not Occur:           X

 

Conditions to Avoid:                 Avoid contact with acids without good agitation. Exercise care if mixing with water as heat is generated with spattering and boiling.

 

Materials to Avoid:                   Acids will cause violent reaction with heat and gas. Contact with aluminum, brass, tin, zinc creates flammable hydrogen gas. Reaction with reducing sugars creates carbon monoxide.

 

Decomposition Products:          Does not decompose.
