discoloration (cyanosis) of skin,
lips or fingernails give oxygen to
breathe. No alcohol or physical
exertion. Contact a physician.

Protection and Procedures for Firefighters
Wear self contained breathing apparatus, and full protective gear. Use water spray to cool containers.
Unusual Fire and Explosion Hazards
Vapors may travel to source of ignition and flash back. Heat can cause polymerization with rapid release of energy which may rupture container
explosively. (Spontaneous polymerization may occur on prolonged storage). Explosion hazard: Fight fire from protected location.
Sensitive to mechanical impact: No. Sensitive to static discharge: Yes.
6. Accidental Release Measures
Containment Techniques
NA
Spill/Leak Clean-Up Procedures and Equipment
Accidental release: Evacuate the area. Eliminate sources of ignition. Use self-contained breathing apparatus and protective clothing. Dike and
absorb with inert material. Transfer to proper containers for disposal, use non-sparking tools. Contaminated monomer may be unstable, add
inhibitor to prevent polymerization. Keep spills and cleaning runoffs out of sewers and open bodies of water. Spills on porous surfaces can
contaminate the groundwater.

7. Handling and Storage
Handling Practices and Warnings
Observe precautions found on the label. Close container after each use. Ground all metal containers when transferring. Use explosion-proof
equipment.
Storage Practices and Warnings
(掳C / 掳F). Store in a cool dry place away from heat, sparks, flame and direct sunlight. Check inhibitor levels every three months.
8. Exposure Control/Personal Protection
Ventilation Other Engineering Controls
Use good, local explosion-proof ventilation with a minimum capture NA
velocity of 100 ft/ min (30 m/ min) at point of monomer release. Refer
to industrial ventilation: A manual of recommended practice published
by the American conference of governmental industrial hygienists.
Local exhaust ventilation is preferred since it prevents contamination
dispersion into the work area by controlling it at its source.
Routes of Entry: Personal Protective Equipment (PPE) for Normal Use: PPE for Emergencies:
Eye/Face Safety glasses or chemical splash goggles. NA
Skin Protective gloves: Impervious, nitrile. NA
Inhalation Respiratory protection: Use self-contained breathing apparatus when NA
needed.
