Concentration: >99%
Impurities: Water (up to 1%), Trace organic byproducts below hazardous thresholds
Inhalation: Move affected person to fresh air, provide oxygen if available, seek medical help immediately if breathing becomes difficult or irritation persists
Skin Contact: Remove contaminated clothing rapidly, rinse skin under running water for at least 15 minutes, seek medical attention for burns, never use neutralizing chemicals on the skin
Eye Contact: Flush eyes thoroughly with water for at least 15 minutes, lift eyelids to ensure thorough rinsing, get immediate medical attention
Ingestion: Rinse mouth with water, do not induce vomiting, never give anything by mouth to an unconscious person, seek immediate medical attention
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical powder or carbon dioxide
Unsuitable Extinguishing Media: Do not use water jet, it could spread the fire
Specific Hazards: Vapors may travel a considerable distance and ignite at remote sources of ignition, toxic and irritating fumes (carbon monoxide, carbon dioxide) may be released during combustion
Protective Equipment: Firefighters wear self-contained breathing apparatus (SCBA) and full protective gear, cool exposed containers with water to prevent rupture
Spill Response: Evacuate area, ventilate the released vapor, clean up using non-sparking tools and chemical absorbents like sand or earth, prevent runoff to drains or waterways
Personal Precautions: Wear appropriate gloves, face shield, goggles, chemical resistant clothing and boots
Environmental Precautions: Block entry into sewers, storm drains and natural water sources, notify authorities if large quantities released
Handling: Work with acid-resistant gloves, eye protection, and lab coats or aprons, handle in a fume hood or well-ventilated area, keep containers closed when not in use to prevent evaporation
Storage: Store away from heat and ignition sources, segregate from oxidizers, strong bases, metals, and reducing agents, use corrosion-resistant containers, maintain temperature below 30°C, mark storage area as corrosive
Incompatible Materials: Bases, oxidizers, chlorides, most metals
Exposure Limit Values: OSHA PEL: 10 ppm (TWA); ACGIH TLV: 10 ppm (TWA), 15 ppm (STEL)
Engineering Controls: Use with local exhaust ventilation, keep airborne levels below exposure limits, ensure eyewash stations and safety showers are nearby
Personal Protective Equipment: Nitrile or butyl rubber gloves, splash goggles, full face shield, chemical-resistant apron and boots, use respirators fitted with acid gas cartridges for insufficient ventilation
