Firefighter Protection
Wear self contained breathing apparatus for fire fighting if necessary.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Wear respiratory protection. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.
Prevent further leakage or spillage if safe to do so.
Do not flush with water.
