Firefighting Procedures: Keep people upwind. Use water spray to cool exposed containers.
Explosion Data: Dust-air mixtures may ignite.
Special Notes: Vapors may be heavier than air and move along ground.
Personal Precautions: Evacuate unnecessary personnel. Use proper protective gear including gloves, goggles, and respirator.
Spill Cleanup: Use non-sparking tools to collect material. Sweep or scoop up cautiously, minimizing dust. Absorb residue with inert material (e.g., sand, earth). Transfer to closed containers for disposal.
Environmental Precautions: Prevent run-off into sewers, streams, or drains. Notify authorities if large amounts enter waterways.
Decontamination: Wash spill area with water and detergent. Collect washings for disposal.
Vapor/Spray Control: Ventilate area well. Close off affected area if possible.
Handling: Use with local exhaust and ventilation. Wear recommended protection. Avoid skin, eye, and respiratory contact. Keep away from food, drinks, and animal feed. Do not reuse container.
Storage Conditions: Store in original, tightly-sealed containers in cool, dry, well-ventilated place. Keep away from incompatible materials (acids, strong oxidizers).
Temperature Sensitivity: High heat accelerates decomposition. Keep away from sunlight and sources of ignition.
Hygiene Practices: Wash hands, arms, and face after use. Change clothing that becomes contaminated.
Incompatibility: Acids, bases, oxidizers, strong reducing agents.
Specific Storage Hazards: Isolate from seed, animal feed, and food products.
Exposure Limits: ACGIH TLV 0.5 mg/m³ (TWA) (as Propoxur dust).
Engineering Controls: Local exhaust ventilation, process enclosure.
Respiratory Protection: NIOSH-approved respirator with particulate filter if above exposure limits.
Eye Protection: Chemical safety goggles.
Skin Protection: Long sleeves, chemical-resistant gloves and apron.
Specific Hygiene Measures: No drinking, eating, or smoking while handling. Shower after shift. Launder clothing before reuse.
Control of Environmental Exposure: Prevent spillage into drains and surface waters.
