Chemical Structure

Control of Substances Hazardous to Health (COSHH) Assessment

  • H225 – Highly flammable liquid and vapour.
  • H319 – Causes serious eye irritation.
  • H336 – May cause drowsiness or dizziness.
  • P210 – Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
  • P261 – Avoid breathing vapours.
