A motor could be an ignition source and could cause flammable gases or vapors in the spill area to burn or explode. Read and follow safety precautions on the solvent label and MSDS. 6.2. Environmental precautions For larger spills, cover drains and build dikes to prevent entry into sewer systems or bodies of water. Collect the resulting residue containing solution. Place in a closed container approved for transportation by appropriate authorities. Dispose of collected material as soon as possible. Clean-up methods Observe precautions from other sections. Call 3M- HELPS line (1-800-364-3577) for more information on handling and managing the spill. Contain spill. Collect as much of the spilled material as possible. Clean up residue with an appropriate organic solvent. In the event of a release of this material, the user should determine if the release qualifies as reportable according to local, state, and federal regulations.

Further information

NFPA Hazard Classification Health 2 Flammability 1 Reactivity 1 Special None National Fire Protection Association (NFPA) hazard ratings are designed for use by emergency response personnel to address the hazards that are presented by short-term, acute exposure to a material under conditions of fire, spill, or similar emergencies. Hazard ratings are primarily based on the inherent physical and toxic properties of the material but also include the toxic properties of combustion or decomposition products that are known to be generated in significant quantities.

HMIS® ratings
