3. Composition / Information on Ingredients

4. First Aid Measures

Ingestion

Ingestion may cause nausea and vomiting. Do not induce vomiting, obtain medical attention.

Inhalation

None envisaged due to the low vapour pressure of the substance.

Skin Contact

Contact with skin may cause slight irritation. Wash with soap and water.

Eye Contact

Contact with eyes may cause slight irritation. Irrigate with copious amounts of water.

Other Information

No other special treatment required.

5. Firefighting Measures

Suitable extinguishing equipment

Fire

Carbon dioxide, dry powder, foam or water fog. Do not use water jets.

HAZCHEM

Combustion products include fluorine compounds, such as hydrogen fluoride.

Special protective equipment and precautions for fire fighters

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures

Spilt product constitutes a slip hazard. Avoid contact with eyes.

Environmental precautions

No special precautions required.

Methods and materials for containment and clean up

Can be wiped from surfaces and residues cleaned with water and detergent.

7. Handling and Storage

Precautions for safe handling

No special precautions required

Conditions for safe storage

No special precautions required.

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

At ambient temperature grease has very low volatility, so development of fumes is highly unlikely. At temperatures approaching 300°C, if thermal decomposition occurs, hydrogen fluoride, carbonyl difluoride and other toxic fumes may be released. Eye washes should be available for emergency use.

Personal protective equipment

Eye and face protection

Safety glasses with side-shields tested and approved under appropriate government standards.

Skin protection

Wash hands after use. For prolonged or repeated skin contact gloves are recommended.

Body protection

Not available

Respiratory protection

None required.
