General Advice: Move person from exposure, seek medical attention
If in Eyes: Rinse immediately with clean, low-pressure running water, hold eyelids open, remove contact lenses, continue rinsing for several minutes
If on Skin: Remove contaminated clothing, wash affected area with mild soap and water, do not scrub, seek medical advice if irritation persists
If Inhaled: Remove to fresh air, keep at rest, seek immediate medical attention for respiratory symptoms
If Swallowed: Rinse mouth, do not induce vomiting, drink water if conscious, seek immediate medical advice
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray (do not use direct stream on burning liquid)
Specific Hazards: Thermally decomposes to release toxic and irritating vapors, such as carbon monoxide, carbon dioxide, hydrogen bromide
Protective Equipment and Precautions: Firefighters use self-contained breathing apparatus and full protective gear, avoid inhalation of combustion products, move containers from fire area if safe to do so
Personal Precautions: Evacuate area, ventilate if possible, wear appropriate personal protective equipment to avoid contact with skin, eyes and inhalation
Spill Cleanup Methods: Absorb with inert material, such as sand or vermiculite, collect into chemical waste containers, avoid raising dust, wash contaminated area with water after removal
Environmental Precautions: Prevent entry to waterways, drains, and soil, notify authorities in event of significant spill
Safe Handling: Work in well-ventilated areas, avoid inhalation or contact with skin and eyes, do not eat, drink, or smoke when handling this product; wash hands and contaminated surfaces after handling
Safe Storage: Store in tightly closed original containers, keep in cool, dry, and well-ventilated place away from heat sources, strong acids and bases, oxidizers; store away from incompatible materials
Occupational Exposure Limit: Not established for 4-Bromoanisole
Engineering Controls: Use chemical fume hood or local exhaust ventilation; eyewash stations and safety showers recommended
Personal Protective Equipment: Protective gloves (nitrile or neoprene), safety goggles or face shield, long-sleeved protective clothing, suitable respiratory protection if ventilation is inadequate; remove contaminated clothing promptly
