Fire Hazards: Vapors may form explosive mixtures with air. Can produce toxic fumes such as carbon monoxide and dioxide when burning.
Special Protective Equipment: Full protective clothing including self-contained breathing apparatus for fire fighters
Advice for Firefighters: Cool sealed containers with water spray to prevent bursting, evacuate area if unsafe. Prevent runoff into drains or watercourses.
Thermal Decomposition Products: Acrid smoke, carbon oxides, possible acrylic monomers
Personal Precautions: Evacuate area, ventilate, avoid inhalation and contact with skin or eyes. Wear chemical-resistant gloves, splash goggles, and appropriate protective clothing.
Environmental Precautions: Prevent entry into sewers, drains, or watercourses. Report release as required by local regulatory bodies.
Containment: Collect spillage using inert absorbent (sand, earth), place in suitable chemical waste container.
Cleaning Methods: Ventilate area, wash non-recoverable residue away with large amounts of water. Properly label and dispose containers.
Decontamination: Decontaminate tools and surfaces to prevent accidental polymerization.
Handling: Use only in well-ventilated areas with explosion-proof equipment. Avoid direct contact with skin, eyes, and clothing. Keep containers tightly sealed when not in use. Ground and bond containers before transfer.
Storage Conditions: Store in a cool, dry, well-ventilated facility away from heat, sparks, direct sunlight, and incompatible chemicals like oxidizers or acids. Use containers lined with compatible materials.
Technical Measures: Maintain proper labeling, keep container upright, use vapour containment systems
Incompatibility: Strong oxidizers, acids, bases, free radical initiators, reducing agents
Storage Temperature: Optimal below 30°C, avoid freezing or overheating
Control Parameters: No established occupational exposure limits for octyl decyl acrylate; monitor for acrylic acid if present as impurity.
Engineering Controls: Use local exhaust, process enclosure, and explosion-proof ventilation to limit vapor accumulation.
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, face shield for bulk work, flame-retardant antistatic garments, impervious footwear.
Respiratory Protection: Wear approved organic vapor respirator in the absence of adequate ventilation, especially for large spills or high vapor environments.
Environmental Controls: Prevent emissions, manage waste, inspect exhaust filtration systems regularly.
Hygiene Measures: Do not eat, drink, or smoke during use. Practice thorough hand washing before breaks and after work.
