Impurities: Trace amounts of inhibitors or stabilizers such as hydroquinone monoethyl ether (HQME) may be present to reduce polymerization risk
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical attention if irritation persists.
Skin Contact: Wash with soap and plenty of water. Remove contaminated clothing and wash before reuse. Seek medical help if reaction or irritation develops.
Inhalation: Move person to fresh air and keep at rest. If breathing becomes labored, call a physician or seek emergency assistance.
Ingestion: Rinse mouth with water. Never give anything by mouth if the person is unconscious. Seek medical attention if large amount swallowed or symptoms develop.
Symptoms: Erythema, itching, swelling, eye stinging, headache, dizziness
Suitable Extinguishing Media: Carbon dioxide, dry chemical, alcohol-resistant foam, water spray
Unsuitable Media: Direct water jet may spread the material
Specific Hazards: May produce toxic fumes of carbon monoxide, carbon dioxide, and irritating acrid smoke under fire conditions. Polymerization under fire can release energy suddenly.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Special Instructions: Move exposed containers if safe; cool surrounding containers with water
Personal Precautions: Use gloves, goggles or face shield, chemical-resistant boots, and suitable protective clothing
Environmental Precautions: Keep out of drains, soil, and surface water; contain spill to prevent environmental release
Cleanup Methods: Absorb spill on inert material such as sand, earth, or clay and place in chemical waste container. Wash area with soap and water.
Preventive Actions: Ventilate area thoroughly. Isolate hazard. Avoid contact with eyes, skin, and clothing. Eliminate all sources of ignition.
Handling: Use only with adequate ventilation. Avoid inhalation or contact with eyes and skin. Do not eat, drink, or smoke when using. Use explosion-proof electrical equipment.
Storage: Store in tightly sealed original container in cool, dry, and well-ventilated place. Keep away from heat, sparks, flames, and direct sunlight. Do not freeze. Avoid storing near incompatible materials such as oxidizing agents or strong acids. Keep out of reach of children.
Incompatibilities: Avoid contact with strong acids, bases, oxidizers, reducing agents
Exposure Limits: No OSHA or ACGIH specific exposure limits; practice good industrial hygiene controls
Engineering Controls: Use local exhaust ventilation or process enclosure to minimize exposure and keep airborne concentrations below any regulatory limits
Personal Protective Equipment: Nitrile or neoprene chemical-resistant gloves; safety goggles with side shields or face shield; impervious protective clothing; suitable respiratory equipment such as NIOSH-approved respirator if ventilation insufficient
Hygiene Measures: Wash hands before breaks and after handling; remove contaminated clothing before eating, drinking, or smoking
