Ingestion
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns.

Inhalation
May cause severe respiratory tract irritation and possible burns.

Skin
May cause severe skin irritation and burns.

Eyes
Contact with eyes may cause severe irritation, and possible eye burns.

Personal Protection
Wear appropriate protective gloves, clothing and goggles.

Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.

Fire Fighting
Use dry chemical, graphite, or dry earth. Use water only if flooding quantities are available. Apply water from as far a distance as possible.

Fire Potential
May explode from friction, heat or contamination. These substances will accelerate burning when involved in a fire.

Small spills/leaks
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Use water spray to disperse the gas/vapor.
