Hazards Identification
【Inhalation】The toxicological properties of this substance have not been fully investigated. Inhalation of dust may cause respiratory tract irritation.
【Skin】May cause skin irritation.
【Eyes】May cause eye irritation.
【Ingestion】May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated.

Exposure Controls/Personal Protection
【Personal Protection】Eyes: Wear appropriate protective eyeglasses or chemical safety ggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
【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.
【Exposure Effects】The toxicological properties of this material have not been investigated.
【Poison Class】F (Not subject to toxicity classification)

Fire Fighting Measures
