Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide for surrounding fires; Product itself is non-combustible
Hazards from Combustion: Under fire conditions, may emit nitrogen oxides and carbon oxides; Fire residues may require specific handling
Protective Equipment for Firefighters: Use self-contained breathing apparatus and full protective gear
Special Fire-Fighting Instructions: Cool containers with water spray; Avoid inhaling decomposition products; Prevent runoff from fire control from entering waterways
Explosion Risk: Does not pose a dust explosion risk under normal conditions
Personal Precautions: Wear dust mask, goggles, and gloves; Avoid creating and inhaling dust; Provide adequate ventilation
Environmental Precautions: Prevent bulk quantities from entering drains and waterways; Use physical barriers to contain spills
Methods for Clean-Up: Sweep up or vacuum using HEPA filter-equipped devices; Collect for disposal in labeled, sealed containers; Wash spill area well with water to remove residue; Avoid using compressed air to minimize airborne particles
Disposal of Contaminated Material: Dispose of waste with attention to local regulations; Do not flush large amounts down the drain
Handling: Minimize dust generation and accumulation; Avoid breathing dust; Use only in well-ventilated areas; Wear protective clothing and equipment; Handle with care to reduce spillage and exposure; Provide washing facilities at points of use
Storage: Store in tightly closed containers; Keep in a cool, dry, and well-ventilated area; Store away from incompatible substances such as strong oxidizers; Protect from moisture; Keep out of direct sunlight
General Hygiene Measures: Do not eat, drink, or smoke while handling; Wash hands thoroughly after work
Container Materials: Compatible with polyethylene, polypropylene, and stainless steel drums or bags; Avoid using aluminum or copper containers
Exposure Limits: No official workplace exposure limits set by OSHA or ACGIH for Melapur 200; Observe general particulate limits for nuisance dust (10 mg/m3 total, 3 mg/m3 respirable fraction)
Engineering Controls: Local exhaust ventilation recommended; Use dust extraction at points of dust generation; Enclosed process equipment preferred
Personal Protection: Respiratory protection through dust mask or respirator (P2 or N95); Safety goggles to protect eyes; Chemical-resistant gloves such as nitrile; Protective work clothing and footwear
Workplace Monitoring: Regular air sampling in risk areas; Maintenance of ventilation systems
