First Aid Measures

Eye Contact: Rinse cautiously under running water for several minutes, remove contact lenses if present, continue rinsing, seek medical attention
Skin Contact: Remove contaminated clothing, wash skin with soap and plenty of water, medical advice recommended if irritation persists
Inhalation: Move affected person to fresh air, keep at rest in a position comfortable for breathing, consult a physician if symptoms develop
Ingestion: Rinse mouth, do not induce vomiting, never give anything by mouth to unconscious person, seek immediate medical advice
Acute Symptoms: Dizziness, sore throat, irritation of airways, abdominal pain, headache; medical monitoring advised in case of continued exposure

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, alcohol-resistant foam, carbon dioxide, sand
Unsuitable Media: Never use water jets directly on product to avoid spread
Specific Hazards: Fires may produce toxic hydrogen bromide fumes and other hazardous decomposition products
Special Protective Equipment: Firefighters use full protective gear and self-contained breathing apparatus, stay upwind, contain run-off with sand or earth
Thermal Hazards: High temperatures may cause containers to rupture violently from pressure build-up

Accidental Release Measures

Personal Precautions: Use appropriate personal protective equipment including gloves, goggles, and respirator if needed, ventilate area thoroughly
Environmental Precautions: Prevent product from entering watercourses and drains, collect spillage, notify environmental authorities if large amounts escape
Containment and Cleaning: Absorb with inert dry material such as vermiculite or sand, place into chemical waste container for disposal, wash spill site after material pick-up is complete, avoid generating dust or vapor

Handling and Storage

Handling: Work inside well-ventilated fume hood, wear recommended PPE, wash hands thoroughly after handling, avoid eating, drinking, or smoking in work area
Storage: Store tightly closed in cool, dry, well-ventilated area away from sources of ignition, segregated from oxidizers, acids, strong bases, and incompatibles, use corrosion-resistant shelving or secondary containment
Special Precautions: Keep out of reach of untrained personnel and children, keep container upright, protect from physical damage and direct sunlight

Exposure Controls and Personal Protection

Exposure Limits: No established ACGIH or OSHA permissible limits for 2-ethylhexyl bromide, minimize exposure as much as possible
Engineering Controls: Chemical fume hood, local exhaust ventilation, mechanical ventilation in enclosed rooms
Personal Protective Equipment: Nitrile or neoprene gloves, chemical splash goggles, lab coat or flame-resistant coveralls, suitable organic vapor respirator if ventilation does not reduce exposure adequately
Hygiene Measures: Remove contaminated clothing immediately, wash hands and exposed skin before breaks and after work, do not reuse PPE until cleaned

Hazardous Decomposition Products: Hydrogen bromide, carbon oxides, small amounts of short chain hydrocarbons when combusted
Polymerization: Product does not undergo hazardous polymerization
Other Significant Reactions: Alkyl halides may slowly react with light or moisture to generate acidic vapors

Toxicological Information

Likely Routes of Exposure: Inhalation, skin absorption, ingestion, eye contact
Acute Toxicity: May cause moderate irritation and tissue damage to skin, eyes, respiratory system, possible central nervous system effects if inhaled
Chronic Effects: Prolonged exposure can lead to dermatitis, respiratory tract irritation, or sensitization
Carcinogenicity: Not listed as a known carcinogen by IARC, NTP, or OSHA; chronic data are limited
Mutagenicity and Teratogenicity: No substantial experimental data available
Target Organs: Eyes, skin, respiratory system
Symptoms of Exposure: Redness, itching, burning, headache, dizziness, weakness, nausea on high exposure

Ecological Information

Environmental Fate: Not rapidly biodegradable, persistent in soil and water
Bioaccumulation Potential: High potential due to hydrophobic structure, can accumulate in aquatic organisms
Aquatic Toxicity: Harmful to aquatic life with long lasting effects, may damage aquatic environments at low concentrations
Mobility in Soil: Likely to adsorb to soil particles and persist, limited leaching expected
Other Adverse Effects: May form toxic degradation products in environment, avoid all unnecessary release

Disposal Considerations

Waste Treatment Methods: Collect and deliver unused or waste material to authorized hazardous waste disposal facility
Disposal of Containers: Triple rinse empty containers, puncture and dispose of as hazardous waste according to local regulations
Sewage Disposal: Do not allow to enter drains, watercourses, or natural bodies of water
Precautionary Disposal: Classified as hazardous waste in many jurisdictions, follow national and local waste regulations strictly
