Protective Equipment: Full protective clothing, self-contained breathing apparatus
Specific Hazards: Containers exposed to heat may rupture or explode, vapors heavier than air, may travel to ignition source and flash back
Special Advice for Firefighters: Approach from upwind, keep containers cool with water spray, prevent run-off from entering waterways or sewers
Personal Precautions: Evacuate area, ventilate, avoid inhalation and contact, use appropriate protective equipment
Environmental Precautions: Prevent further leakage or spillage if safe, contain with earth or sand, avoid entry into drains, surface water, or soil
Cleaning Methods: Absorb small spills with inert material (sand, earth, vermiculite), collect into chemical waste containers, flush spill area with water after removal
Large Spills: Dike with non-combustible absorbents, notify local authorities if environmental contamination occurs
Decontamination: Use neutralizing solution (sodium bicarbonate) on residues; ensure all responders fully equipped
Handling: Operate in well-ventilated areas; avoid breathing vapors; do not eat, drink, or smoke during operation; wear acid-resistant gloves, eye, and face shields
Safe Work Practices: Keep away from heat, ignition sources, oxidizers; ensure proper labeling on containers; use only non-sparking tools

Segregation: Separate from food and animal feed, store below 30°C
Technical Controls: Eye-wash stations and emergency showers accessible in work area
Occupational Exposure Limits: ACGIH TLV – 10 ppm (TWA), 15 ppm (STEL); OSHA PEL – 10 ppm (TWA)
Engineering Controls: Mechanical exhaust or local fume hoods to control vapor levels
Personal Protective Equipment: Acid-resistant gloves, chemical splash goggles, face shield, lab coat or acid-impervious apron, respirator for high vapor concentrations
