3. PRECAUTIONS FOR USE
3.1 Exposure Standards
TWA: 1 ppm 6.1 mg/m3
3.2 Engineering Controls
Use adequate general or local exhaust ventilation to keep airbourne concentrations below permissible exposure limits.
3.3 Personal Protection
On exposure to the molten product, a full faced industrial gas mask with canister of type A (brown) should be provided. Wear a dust filter mask when handling. Use PVC or plastic gloves. Safety goggles or face shield. Avoid contact with skin, eyes and clothing. Wash oneself immediately and take off contaminated clothing. Keep away from foodstuffs. Wash hands at every break of work.
3.4 Flammability
Dusts may form explosive mixtures in air. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Store in a cool, dry, well ventialted place away from sources of ignition and heat. Keep containers tightly sealed. Molten : maintain under Nitrogen. Do not ingest or inhale and avoid contact with skin and eyes. Avoid contact with oxidising materials and alkalies. Keep away from foodstuffs. Avoid raising dusts. Take precautionary measures against static discharge.

Risk Phrases R36/37/38 Irritating to eyes, respiratory system and skin.
Safety Phrases S2 Keep out of the reach of children.
4.3 Spills and Disposal
Spills
Clean-up personnel should wear full protective clothing including breathing protection in dusty environments. Avoid raising dust. Do not allow product to enter drains, water courses or sewers.
Take up with absorbant material(eg. sand, chemical absorbants). Neutralise with soda or sodium bicarbonate and collect for disposal. Wash spill site with copious amounts of water after pickup is complete.
Disposal
Dispose according to all local, state and federal regulations. Incineration is the preferred method, incinerate in an approved combustion plant.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Wear usual fire protective clothing and self-contained breathing apparatus. Dust may form explosive mixtures with air ; flakes can develop static charges - equipment should be electrically ground. Products of combustion are toxic. Cool fire-exposed containers with water spray.
Extinguishing Media
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. Use water, halones, foam, carbon dioxide or dry powder type extinguishers. Use equipment/media appropriate to surrounding fire conditions. 5 OTHER INFORMATION
Other Information
Dust forms flammable mixtures with air and can develop static charges. Minimum explosion limits for the dust 15g/m3. Ecological and exotoxicological information: Fish toxicity LC50: 313 mg/l/48hr (golden orfe) Water danger/protection: WGK 0 - generally not dangerous to the water.
