1. Storage: Store in a cool, dry place. Keep container closed when not in use. Keep under a nitrogen blanket. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
2. Handling: Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid breathing dust, vapor, mist, or gas. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
3. Personal Protection: Eyes: Wear appropriate protective eyeglasses or chemical safety goggles 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.
4. Fire Fighting: Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Do NOT use carbon dioxide or dry chemical. DO NOT USE WATER! Cool containers with flooding quantities of water until well after fire is out.
