Immediate Medical Attention Needed: Exposure may result in serious health impacts. Health professionals should monitor for respiratory distress, chemical burns, and treat symptomatically.
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry powder, carbon dioxide. Select agent appropriate for surrounding fire and material compatibility.
Unsuitable Media: Avoid high-pressure water jet; may cause chemical to spread.
Special Hazards: Product does not burn readily but toxic hydrogen fluoride, sulfur oxides, carbonyl fluoride, and perfluorinated compounds may evolve if strongly heated or combusted with other organics.
Protection for Firefighters: Wear self-contained breathing apparatus and full chemical protective suit. Avoid inhalation of decomposition products. Move product containers away from fire area if safe to do.
Advice for Emergency Responders: Evacuate non-essential personnel. Keep out of low areas where vapors may settle. Prevent run-off from fire-fighting from entering waterways.
Personal Precautions: Restrict access to spill area. Equip responders with suitable respirators, full chemical-resistant suits, gloves, goggles. Isolate spillage from sources of ignition and waterways.
Methods for Containment: Prevent further leakage. Use compatible absorbent (vermiculite, dry sand). Do not allow to contact strong bases or oxidizers.
Cleanup Procedures: Collect spilled product in containers labeled for hazardous materials disposal. Rinse surfaces thoroughly with water and detergent solution, collect washings for safe disposal.
Environmental Precautions: Avoid release to land, water, drains. Notify authorities of contamination to environment. Consider using booms or dikes to control large releases.
Decontamination: Ventilate area. Remove contaminated clothing and gear for safe cleaning or disposal.
Safe Handling: Handle in fume hood or well-ventilated area. Wear protective equipment at all times. Avoid breathing dust, vapors, mist. Never eat, drink or smoke near product use area. Maintain proper hygiene.
Storage: Keep container tightly closed in a dry, cool, well-ventilated location. Store away from heat, direct sunlight and incompatible materials such as strong oxidizing agents or alkalis. Use corrosion-resistant containers.
Other Storage Information: Keep away from strong light sources. Protect from moisture and temperature extremes. Segregate from food, feed, and drinking water.
Technical Measures: Use containment and exhaust ventilation to minimize release. Bulletin board with emergency contacts and spill protocols must be visible near storage area.
Engineering Controls: Use local exhaust ventilation, process enclosures or laboratory hoods to maintain airborne levels below occupational exposure limits. Environmental engineering controls must limit emission to outside air.
Personal Protective Equipment: Chemical splash goggles or face shield; gloves (nitrile, neoprene or other chemical-resistant material); lab coat or chemical suit; closed footwear.
Respiratory Protection: Approved respirators (e.g., NIOSH N100/P100 or equivalent) required at high exposure levels or during spill response.
Monitoring: Airborne concentrations should be measured regularly in occupational settings. Biological monitoring may be necessary for employees working with this compound.
Hygiene Measures: Avoid contact with skin, eyes, and clothing. Remove contaminated personal protective equipment before leaving work area. Wash hands after handling.
