Nature of Hazardous Components: Single hazardous active ingredient
Inhalation: Remove individual to fresh air. Seek medical help if symptoms persist. Monitor for respiratory distress during evacuation.
Skin Contact: Remove contaminated clothing. Wash skin with mild soap and plenty of water for at least 15 minutes. Seek medical attention if irritation continues.
Eye Contact: Rinse eyes with gentle stream of water for at least 15 minutes, lifting eyelids frequently. Get medical advice immediately.
Ingestion: Rinse mouth with water. Do not induce vomiting. Get medical attention quickly.
Recommendations for Physicians: Symptomatic treatment for irritation and respiratory effects.
Emergency Medical Attention: Prompt attention required for pulmonary or dermal reactions.
Suitable Extinguishing Agents: Water spray, fog, or flooding in large quantities. Dry chemicals, foam, or CO₂ not recommended.
Fire/Explosion Hazards: Releases toxic nitrogen oxides when burned. Explodes if heated or subjected to impact.
Protective Equipment: Firefighters should use self-contained breathing apparatus, protective chemical-resistant gear.
Specific Firefighting Methods: Keep material cool with water spray. Isolate area. Approach from upwind.
Special Precautions: Remove all personnel not directly involved. Avoid sparks, open flames, static discharge.
Personal Precautions: Evacuate non-essential personnel. Restrict access to site.
Protective Equipment: Wear chemical-resistant suit, goggles, dust mask or respirator.
Environmental Precautions: Block entry into waterways, sewers, soil. Minimize airborne dispersion. Notify environmental authorities.
Cleanup Methods: Do not sweep or use vacuum cleaners. Shovel up gently and transfer to safe container for disposal.
Decontamination: Wash spill site with copious amounts of water. Avoid run-off.
Disposal of Collected Material: Dispose per local, state, and federal regulations for hazardous waste.
Safe Handling Advice: Use spark-proof tools. Prevent build-up of static electricity. Handle in explosion-proof areas.
Hygiene Measures: Wash hands thoroughly after handling. Remove contaminated clothing before leaving work area.
Storage Conditions: Store in tightly closed, labeled containers. Keep away from heat, open flames, oxidizing agents, direct sunlight.
Temperature Requirements: Cool, dry, and well-ventilated location below 25°C (77°F). Avoid humidity.
Container Recommendations: Materials compatible with energetic compounds, free from metal contamination.
Incompatibilities: Strong acids, bases, oxidizers, metals like copper/iron which can catalyze decomposition.
Exposure Limits: No established OSHA or ACGIH limits for nitroguanidine. Employers should limit exposure as low as reasonably achievable.
Engineering Controls: Local exhaust ventilation, explosion-proof systems, segregated prep rooms.
Eye Protection: Tight-fitting chemical splash goggles.
Skin Protection: Impervious chemical gloves (nitrile, neoprene), long sleeves, suitable footwear.
Respiratory Protection: NIOSH/MSHA-approved particulate respirators for dust.
