SECTION 5. FIREFIGHTING MEASURES
Flash Point: n/a
Suitable extinguishing media: Carbon dioxide, dry chemical powder, alcohol foam, water spray.
Water or foam may cause frothing.
Unsuitable extinguishing media : Water jet
Special hazards arising from the substance or mixture: Carbon monoxide and carbon dioxide and
Advice for firefighters: In the event of a fire, wear full protective clothing and approved self-contained
breathing apparatus. Fight fire from a safe distance or protected location. Under
certain conditions a dust cloud of calcium stearate can explode when ignited by a
spark, flame or other ignition source. Must avoid generating dust to minimize risk
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal protective equipment:
Eye - Wear appropriate protective safety glasses
Skin – Wear appropriate protective gloves and clothing. Put on an appropriate respirator
Containment: Keep unnecessary personnel away. Eliminate all sources of ignition.
Do not allow the spilled product to enter sewers or open waterways
Clean-up Procedures: Dust deposits should not be allowed to accumulate on surfaces, as these may form
an explosive mixture if they are released into the atmosphere in sufficient concentration. Avoid the
generation of dust during the clean-up. Vacuum spills or cover with damp sand or saw-dust if sweep. No sparking tools should be used
SECTION 7. HANDLING AND STORAGE
Handling: Open packaging bag carefully, avoid spillage and dust formation and control ignition sources.
Use this product with adequate ventilation. Wash hands after handling.
Storage: Store in cool, dry place to avoid the effects of heat and moisture. Keep container tightly closed and properly labeled. Avoid exposure to sunlight, heat and spark. Ground all equipment containing material.
Minimize dust generation and accumulation. Routine housekeeping should be instituted to ensure that dusts do not accumulate on surfaces. Dry powders can build static electricity charges when subjected to the friction of transfer and mixing operations. Provide adequate precautions, such as electrical grounding and bonding, or inert atmospheres.
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure limit: ACGIH TLV: TWA 10mg/m3 (Total),
Engineering controls: General room ventilation plus local exhaust at points of
emission to maintain levels of airborne contaminants
below exposure limits.
Personal protective equipment
Respiratory: An appropriate dust respirator. Should be used as a
precautionary measure where airborne contaminants
Eye: Safety glasses. A face-shield, if the situation requires.
Hand: Protective gloves
Body: Overall or dust cloth, change daily.
