Specific Hazard: Combustible. Releases toxic gases in fire conditions. Containers may burst if exposed to heat for prolonged periods.
Fire-Fighting Procedures: Cool adjacent containers with water spray. Remove unaffected containers from fire area if safe. Use caution, as vapors are heavier than air.
Personal Precautions: Evacuate area. Wear proper PPE such as gloves, chemical-resistant suit, safety goggles, and respirator. Avoid inhalation of vapors and contact with skin or eyes.
Environmental Precautions: Prevent product from entering waterways, drains, or soil. Notify authorities if significant spill reaches environment.
Containment Methods: Cover drains. Surround spill with inert absorbent (sand, clay, vermiculite).
Cleanup Procedure: Scoop up absorbed material and collect for disposal in sealed containers. Wash area with water and detergent. Ensure proper ventilation after cleanup.
Decontamination: Wash remaining traces of chemical with large quantities of water.
Safe Handling: Use only in well-ventilated areas. Avoid all sources of ignition. Wear protective gear—chemical-resistant gloves, long-sleeved clothing, and eye protection. Use personal respirator for dusty or vapor-prone environments.
Precautions: Avoid ingestion, inhalation, and skin or eye contact. Do not eat, drink, or smoke in work area.
Storage Conditions: Store in cool, dry, well-ventilated place away from incompatible materials. Keep container tightly closed. Do not store near acids, oxidizing agents, or sources of ignition.
Specific Storage Requirements: Use corrosion-resistant containers. Label storage containers properly.
Incompatibilities: Strong acids, oxidizers, acid chlorides, and acid anhydrides.
Exposure Limits: No OSHA or ACGIH exposure limits established for this compound. Use workplace exposure monitoring for airborne concentrations.
