Most Important Symptoms: Burning sensation, redness, possible blistering, headache, respiratory tract irritation, nausea.
Special Note to Physician: Treat symptomatically. Risk of pulmonary edema and chemical pneumonitis.
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide. Never use straight water stream on burning liquid.
Specific Hazards Arising: Substance is an organic peroxide and poses risk of violent decomposition under heat. Container may explode if heated or involved in fire. Can release irritating and toxic fumes such as carbon monoxide, carbon dioxide, acids.
Protective Equipment: Firefighters require positive pressure self-contained breathing apparatus and full chemical protective clothing.
Special Procedures: Cool exposed containers with flooding quantities of water. Remove containers if safe.
Explosion Hazard: Avoid friction, shock, impact, and contamination with combustible material.
Decomposition Products: Carbon oxides, hydrocarbons, possible peroxides.
Personal Precautions: Evacuate non-essential personnel. Use chemical splash goggles, rubber gloves, chemical-resistant suit. Ensure proper ventilation and avoid breathing vapors.
Spill Response: Remove all ignition sources. Stop leak if safe. Contain released material with inert absorbent (sand, vermiculite). Do not use combustible absorbents.
Cleanup Methods: Collect in tightly sealed chemical waste containers. Extensive water rinse required for small residues. Avoid runoff into drains or waterways.
Environmental Precautions: Prevent contamination of soil, watercourses, and sewers. Notify environmental authorities if large spill occurs or if water pollution risk exists.
Decontamination: Wash spill area thoroughly after cleanup with soap and water, collect rinsate for disposal.
Handling: Use only in explosion-proof areas with adequate air exchange. Wear suitable PPE including gloves, goggles, long sleeves. Use non-sparking tools. Prevent static discharge. Avoid rough handling, dropping, or shaking. Do not return unused product to original container.
Storage: Store in tightly closed original containers at temperatures below 30°C, away from incompatible materials such as acids, bases, reducers, and combustibles. Keep in dry, well-ventilated area, out of direct sunlight. Separate from food and drink. Protect from physical damage.
Special Storage Requirements: Install temperature alarms. Isolate from other chemicals. Install bunds for large storage tanks.
Incompatibilities: Strong acids, strong bases, reducing agents, heavy metals. Avoid contact with materials containing active hydrogen.
Engineering Controls: Local exhaust ventilation, explosion proof electrical fittings, chemical fume hood.
Occupational Exposure Limits: No established OSHA or ACGIH limits, follow guidelines for nuisance dust or similar peroxides.
Personal Protective Equipment: Butyl rubber or laminate gloves, safety goggles with side shields, chemical resistant apron or suit. Respiratory protection: organic vapor respirator if ventilation insufficient.
Hygiene Measures: Do not eat, drink, or smoke while using product. Wash hands before breaks and after work.
