Fire-Fighting Measures

Suitable Extinguishing Media: Use foam, dry chemical powder, or carbon dioxide
Special Hazards: Releases hydrogen bromide and carbon oxides when involved in a fire
Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical protective clothing
Firefighting Advice: Stay upwind of fire, avoid breathing smoke, use water spray to cool containers and prevent dust dispersion
Flammability: Product is combustible at high temperatures, avoid open flames or sparks near storage

Accidental Release Measures

Personal Precautions: Evacuate personnel, use personal protective equipment including gloves, goggles, and chemical-resistant clothing
Environmental Precautions: Prevent entry into drains, surface water, or soil
Cleanup Methods: Absorb spillage with sand or inert material, collect in suitable containers for proper disposal, ventilate the area thoroughly, clean contaminated surfaces with soap and water

Handling and Storage

Handling: Avoid inhalation, prevent contact with skin and eyes, use local ventilation, handle with proper chemical hygiene
Storage Conditions: Store in tightly closed containers, keep in a cool, dry, and well-ventilated area away from incompatible substances such as strong bases, acids, and oxidizers
Incompatibilities: Strong bases, strong oxidizers, reducing agents, heat sources
Container Materials: Use containers compatible with organic esters and acids, such as glass or certain plastics

Exposure Controls and Personal Protection

Engineering Controls: Use chemical fume hood, localized exhaust ventilation
Respiratory Protection: NIOSH-approved respirator or dust mask where exposure is possible
Eye Protection: Tight-fitting chemical splash goggles
Skin Protection: Impermeable gloves (nitrile, neoprene), lab coat with long sleeves, closed footwear
Hygiene Measures: Wash hands before breaks and at the end of work, remove contaminated clothing immediately

Respiratory or Skin Sensitization: No reliable data indicates significant sensitization
Chronic Effects: Prolonged exposure may result in dermatitis or central nervous system effects
Carcinogenicity, Mutagenicity, Reproductive Toxicity: Not classified as carcinogenic, mutagenic, or toxic to reproduction in available studies

Ecological Information

Ecotoxicity: Toxic to aquatic organisms, may cause adverse effects in aquatic environments
Mobility in Soil: Tends to partition to soil/sediment from water due to hydrophobic structure
Persistence and Degradability: Not readily biodegradable, persistent in soil and water
Bioaccumulation: Potential for bioaccumulation is high based on partition coefficient estimates
Other Adverse Effects: Avoid release to the environment, due to potential long-term aquatic impact

Disposal Considerations

Disposal Methods: Collect into tightly sealed containers, hand over to authorized chemical waste disposal contractor
Contaminated Packaging: Offer rinsed containers for recycling or disposal as hazardous waste, never reuse packaging for food or drink
