Extinguishing media:

All generally used extinguishing media may be used: water; dry chemical; foam; carbon dioxide or sand

Extinguishing media which must not be used for safety reasons:

Not known according to previous experience.

Special procedures:

Evacuate all non emergency personnel to a safe area. Fire fighters should use self contained breathing apparatus. Avoid breathing smoke, fumes and decomposition products. Use water spray to quench smouldering materials. Burning produces intense heat, toxic gases and dense smoke.

Reactivity Data

Stability:

Stable, no known conditions to avoid. If stored and handled in accordance with standard industrial practices, no hazardous reactions are known.

Incompatibility:

Not Applicable

Hazardous decomposition products:

Decomposition begins above 250^oC, but at this temperature fumes are innocuous. Above 300^oC more complex breakdown occurs and the resulting fumes are irritants. Carbon monoxide (CO), carbon dioxide (CO₂) and low molecular weight compounds under certain conditions.

Hazardous polymerisation:

Will not occur

Exposure limits:

N/A

Skin contact:

N/A

Skin absorption:

N/A

Eye contact:

In the form of shavings or dust only. Abrasion hazard from machining or grinding

Inhalation:

N/A

General information:

According to present experience, the material is physiologically compatible and is neither mutagenic, carcinogenic or teratogenic.

Accute toxicity:

No data known

Preventive Measures

Respiratory protection:

No special precautions necessary. When grinding use a dust mask, as material will produce a nuisance dust if no coolant or extraction equipment is used

Ventilation:

As required to avoid nuisance dust

Long term EL (8 hrs):

No standard

Protective gloves:

N/A

Eye protection:

Protective glasses if grinding or machining

Other protective equipment:

N/A

Handling precautions:

N/A

Spills:

N/A

Waste disposal:

Dispose as solid waste according to local laws

First Aid Measures

Swallowing:

No special measures necessary. Give water to drink.

Skin:

It is good personal hygiene practice to wash hands after handling.

Inhalation:

No special precautions are necessary. Avoid inhalation of dust and decomposition products by use of adequate ventilation. If coughing or other respiratory symptoms occur, the person should seek fresh air and if they persist, see a physician.

Eyes:

Flush or remove dust particles as with any other non hazardous substances. Continue to rinse for at least 15 minutes and obtain medical attention in case of continuous irritation.
