Suitable extinguishing media : The product itself does not burn.
Use extinguishing measures that are appropriate to local
circumstances and the surrounding environment.
Unsuitable extinguishing
media

fire.
Special hazards arising from the substance or mixture
Specific hazards during
firefighting
: In case of fire hazardous decomposition products may be

Advice for firefighters
Special protective equipment
for firefighters
: In the event of fire, wear self-contained breathing apparatus.
Further information : Standard procedure for chemical fires.

regulations.

Handling and storage

Precautions for safe handling
Advice on safe handling : Avoid formation of dust and aerosols.
Handle with care to avoid abrasion or breakage.
Advice on protection against
fire and explosion
: In case of inappropriate handling, spent catalyst can be selfheating
when in contact with air.

Stability and reactivity

Reactivity
No dangerous reaction known under conditions of normal use.

Chemical stability
No decomposition if stored and applied as directed.

Possibility of hazardous reactions
Hazardous reactions : Metal catalysts can form Metal carbonyl M x(CO)y in the
presence of carbon monoxide. Metal carbonyl is highly
flammable and highly toxic and can cause cyanosis and
chemical pneumonia which can be fatal. Symptoms may be
delayed for several hours or days. Extreme care and
specialized handling is required if carbon monoxide is present
in the catalyst process. Hazardous reactions are possible at
temperatures including, but not limited to, ambient
temperatures depending on pressure and carbon monoxide
concentrations.

Conditions to avoid
Conditions to avoid : Avoid dust formation.

Incompatible materials
Materials to avoid : Acids and bases

Hazardous decomposition products
No decomposition if stored and applied as directed., In case of fire hazardous decomposition
products may be produced such as:, see heading 5

Disposal considerations

Waste treatment methods
Product : Refer to manufacturer/supplier for information on
recovery/recycling.
Used catalysts may have different hazards or properties than
the original product. This SDS does not apply to used
catalysts.
Contaminated packaging : Dispose of as unused product.
