Section 5 - Fire Fighting Measures 
5.1 Extinguishing media
Suitable extinguishing media
Dry chemical, foam, carbon dioxide.
5.2 Unsuitable extinguishing media:
Water (It may scatter and spread fire.)
5.3 Specific hazards arisingfrom the chemical:
Take care as it may decompose upon combustion or in high temperatures togenerate poisonous fume..
5.4 Precautions for firefighters:
Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place. In case of fire in the surroundings: Keep containers cool by spraying with water. Eliminate all ignition sources if safe to do so.
5.5 Special protectiveequipment for firefighters:
When extinguishing fire, be sure to wear personal protective equipment.

Section 6 - Accidental Release Measures 
6.1 Personal precautions, protective equipment and emergency procedures
Use extra personal protective equipment (self-contained breathing apparatus). Keep people away from and upwind of spill/leak. Ensure adequate ventilation. Entry to non-involved personnel should be controlled around the leakage area by roping off,etc.
6.2 Environmental precautions
Prevent product from entering drains
6.3 Methods and materials for containment and cleaning up
Absorb spilled material in dry sand or inert absorbent before recovering it into an airtight container. In case of large amount of spillage, contain a spill by bunding.Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
6.4 Prevention of secondary hazards:
Remove all sources of ignition. Fire-extinguishing devices should be prepared in case of a fire. Use spark-proof tools and explosion-proof equipment.

Section 7 - Handling and Storage 
7.1 Precautions for safe handling
Avoid contact with skin and eyes. Avoid formation of dust and aerosols.

Provide appropriate exhaust ventilation at places where dust is formed.
For precautions see section 2.2.
7.2 Technical measures:
Handling is performed in a well ventilated place. Wear suitable protective equipment. Be careful not to cause leakage, overflow, or dispersion. Steam should not be
generated unnecessarily. Keep away from heat/sparks/open flame/hot surfaces. –No smoking. Take measures to prevent the build up of electrostatic charge. Use explosion-proof equipment. Avoid shock and friction. Wash hands and face before breaks and immediately after handling the product.
Use a closed system if possible. Use a ventilation, local exhaust if vapour or aerosol will be generated.
7.3 Advice on safe handling:
Avoid contact with skin, eyes and clothing. May develop pressure. Open carefully.

Section 8 - Exposure Controls, Personal Protection 
8.1 Control parameters
Components with workplace control parameters
8.2 Exposure controls
Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
Personal protective equipment
Eye/face protection
Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. 
Body Protection
Choose body protection in relation to its type, to the concentration and amount of dangerous substances, and to the specific work-place., The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. 
Respiratory protection
Respiratory protection is not required. Where protection from nuisance levels of dusts are desired, use type N95 (US) or type P1 (EN 143) dust masks. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). 
Control of environmental exposure
Do not let product enter drains.
