Inhalation: Remove to fresh air immediately, keep victim at rest, consult medical personnel if symptoms like headache, dizziness, or breathing difficulties appear or worsen, supply oxygen if breathing feels labored
Skin Contact: Remove contaminated clothing and shoes quickly, wash affected skin thoroughly using soap and plenty of water for at least 15 minutes, seek medical advice if irritation, sensitization, or redness develops

Ingestion: Do not induce vomiting unless instructed by medical provider, rinse mouth, seek urgent medical assistance, never give anything by mouth to an unconscious person
Self-protection: For responders: use chemical-resistant gloves and goggles, avoid direct contact, move victim away from source area for safety
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, spray water for cooling (not for direct extinguishing), do not use direct water stream as substance may float and spread fire
Unsuitable Media: Direct high-pressure water since product may spread
Special Hazards: Carbon monoxide, carbon dioxide, smoke, unidentifiable toxic gases likely released on combustion, heated vapors heavier than air may travel to ignition sources
Equipment for Firefighters: Wear positive pressure self-contained breathing apparatus (SCBA) and full chemical-resistant gear, do not breathe smoke or vapors
Further Instructions: Stay away from spill site, use remote application of water to cool adjacent containers, avoid contaminated runoff entering drainage
Spill Cleanup: Evacuate area, eliminate ignition sources, use non-sparking tools, ventilate affected zone, wear personal protective equipment including splash goggles, chemical-resistant gloves, coveralls, containment by diking with inert absorbent like sand or earth (avoid sawdust), collect spilled material for disposal in approved containers, clean area thoroughly
Preventive Controls: Stop leak if safe, prevent entry into sewers, storm drains, or waterways
Environmental Precautions: Notify proper authorities if product becomes an environmental release, do not allow to reach ground water or surface water
Decontamination: Wash spill residues with water and detergent, properly dispose of all contaminated cleanup materials
Safe Handling: Avoid all personal contact, handle only within well-ventilated spaces or dedicated chemical fume hoods, use explosion-proof equipment, ground all containers during transfer, keep away from strong acids, oxidizers, bases, open flames, hot surfaces, never eat, drink or smoke in handling area
Hygiene Practices: Wash hands and face thoroughly before breaks or eating, remove contaminated clothing and wash before reuse, ensure eyewash stations and emergency showers are accessible
Storage: Keep in tightly closed original container in a cool, dry, ventilated setting, store away from direct sunlight, separate from incompatible compounds (oxidizers, acids, bases), secondary containment to guard against leaks, label storage area clearly, safeguard containers against damage and inspect regularly
Occupational Exposure Limits: No formal OSHA PEL or ACGIH TLV for nonylphenol, aim for minimal exposure, follow local regulations
Engineering Controls: Local exhaust ventilation, process enclosure, general room ventilation for airborne concentration control
Personal Protective Equipment: Safety goggles or face shield for splash hazard, nitrile or neoprene gloves, long-sleeved chemical-resistant clothing, use respirator if ventilation is poor or airborne concentrations rise, use certified organic vapor cartridges if needed
Environmental Controls: Prevent chemical from entering drains or waterways, install spill containment where large quantities handled
