Protective Equipment: Wear self-contained breathing apparatus, full turn-out gear, approach fire from upwind to avoid hazardous vapors
Firefighting Instructions: Use water spray to cool containers, prevent build-up of pressure, remove containers from fire area if safe, watch for sudden violent boiling
Hazardous Combustion Products: Carbon monoxide, acrylate vapors, formaldehyde traces
Explosion Data: Vapors heavier than air, can move along surfaces; ignition sources remote from leak may ignite vapor cloud
Personal Precautions: Evacuate non-essential personnel, ventilate area, eliminate ignition sources, wear chemical-resistant protective equipment
Environmental Precautions: Prevent entry into drains, soil, watercourses, use diking to contain spill, notify authorities in case of significant release
Methods for Containment: Stop leak safely, use inert absorbent (sand, earth, vermiculite) for small spills, collect and store in closed, labeled containers
Cleaning Methods: Wash area with water and detergent after removal, ventilate area thoroughly, handle waste per disposal considerations
Decontamination: Avoid dispersal of dust or vapor, use non-sparking tools and grounded equipment
Handling: Use only under well-ventilated conditions, avoid skin and eye contact, prevent inhalation, wear protective equipment, use spark-free tools, ground all equipment, transfer slowly to prevent static discharge, open containers carefully
Storage Conditions: Store in tightly closed, chemical-resistant containers, keep cool (below 25°C/77°F), protect from sunlight and heat, keep away from acids, oxidizers, and combustibles, maintain inhibitor concentration to prevent polymerization
Incompatible Materials: Strong oxidizers, acids, bases, amines
Specific End Use(s): Monomer for polymer manufacture, crosslinking with other acrylates, laboratory research, specialty chemical production with control
Occupational Exposure Limits: No established OSHA/NIOSH REL, company recommends minimal exposure via engineering controls
Engineering Controls: Use local exhaust ventilation, process enclosures, ensure proper solvent storage, monitor vapor levels
Personal Protective Equipment (PPE): Splash-proof goggles or face shield, chemical-resistant gloves (nitrile, neoprene), impermeable aprons, closed shoes, flame-resistant lab coats, avoid contact lenses
