are swallowed, get medical attention immediately.

Section 5: Fire Fighting Measures

Dangerous data:

Flammable at sight of fire or under high temperature.

Harmful products after firing:

Carbon oxides (CO、CO2), sulfur oxides, and sodium oxide.

Fire Fighting Methods:

Firemen should wear anti-poison face-mask and protective clothes, the air flow

should direct upward.

Fire Fighting Agent:

Water spray, foam, carbon dioxide or sand soil.

Section 6: Accidental Release Measures

Separate the leakage contaminated area, limit in and out. Cut off the fire source.

It’s suggested that the workman should wear anti-dusk face masks which can

cover the whole face, and wear anti-poison clothes. Collect the products into bags

avoiding dust rising and move to safe place. If large spill, cover the products with

plastic cloth or canvas. Collect and reclaim or send to the waste disposal site.

Section 7: Handling and Storage

Handling Precautions:

Keep the containers closed but workroom ventilation. Workmen should be

specially trained, and handle according to regulation. Workmen are suggested

wearing self-contained breathing apparatus, splash goggles, wear anti-poison

work suits and rubber hand suits. Keep away from fire and heat. No smoke. Adopt

ant-explosive ventilation appliances. Avoid dusts. Keep away from incompatible

materials such as oxidizing agents. Handle carefully during upload or download to

avoid the container damage. Equip with suitable types and quantities of fire

fighting and spill handling appliances. Hazardous matter may remain in empty

containers.

Storage Precautions:

Keep container in a cool, well-ventilated place, tightly closed. Keep away from fire

and heat. Store in well-ventilation room, in case of insufficient ventilation, wear

suitable respiratory equipment. No contact with strong oxidizing agents or acid.

Prepare appropriate containers to accommodate the spilled materials.
