| Exposure limits |
TLV-TWA 50 ppm (～212 mg/m3) (ACGIH and NIOSH), 100 ppm (～425 mg/m3) (OSHA and MSHA); ceiling 200 ppm, peak 600 ppm/5 min/3 h (OSHA); STEL 100 ppm （～425 mg/m3) (ACGIH). |
| Stability: |
Stable, but may polymerize upon exposure to light. Normally shipped with a dissolved inhibitor. Substances to be avoided include strong acids, aluminium chloride, strong oxidizing agents, copper, copper alloys, metallic salts, polymerization catalysts and accelerators. Flammable - vapour may travel considerable distance to ignition source |
