Eye Contact: Immediately flush eyes with gently flowing water for at least 15 minutes, keeping eyelids open
Skin Contact: Remove contaminated clothing, rinse affected skin with plenty of water, seek medical attention for persistent irritation
Inhalation: Move to fresh air, monitor for breathing difficulty, provide oxygen if breathing becomes labored, seek medical care
Ingestion: Rinse mouth with water, never give anything by mouth to an unconscious person, seek immediate medical advice
Notes for Physician: Treat symptomatically, monitor for respiratory symptoms triggered by sensitization or inhalation
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, foam, or water spray to control fire
Unsuitable Extinguishing Media: Direct water stream may spread burning liquid
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, irritating vapors, phenolic compounds
Special Protective Equipment: Firefighters require self-contained breathing apparatus and full protective gear
Fire and Explosion Hazards: Vapor may form explosive mixture with air, containers exposed to heat may rupture
Personal Precautions: Evacuate area, avoid breathing vapors, ventilate area, wear appropriate personal protective equipment as specified in Section 8
Environmental Precautions: Prevent further leakage or spillage if safe to do so, contain spill to prevent entry into waterways or soil
Methods for Containment and Clean-Up: Absorb spilled material with inert material such as sand or earth, collect and place in containers for disposal, clean contaminated surfaces with a suitable cleaning agent, ventilate area
Precautions for Safe Handling: Use in well-ventilated areas, avoid inhalation of vapors, avoid contact with skin and eyes, ensure appropriate exhaust ventilation at workplaces, keep containers tightly closed
Conditions for Safe Storage: Store in a cool, dry, well-ventilated place, protect from sunlight, keep away from incompatible substances such as strong oxidizers, acids, store in tightly sealed original container, keep container in secondary containment if possible
Engineering Controls: Use local exhaust ventilation or other engineering controls to keep airborne concentrations below recommended exposure limits
Personal Protective Equipment:
Hand Protection: Chemical-resistant gloves such as nitrile or neoprene
Eye Protection: Safety goggles or face shield
Skin and Body Protection: Long-sleeved clothing, chemical-resistant apron if risk of splashing
Respiratory Protection: If ventilation is inadequate, use an approved respirator or supplied air respirator
Exposure Limits: No established OSHA or ACGIH limits for piperonal propyleneglycol acetal, minimize exposure by employing best industrial hygiene practices
