Extinguish allsources of ignition, be aware that vapour may travel some way towards sources of ignition.
Any hazardous waste generated from an emergency situation must be assigned a Type Code and Hazard Classification number(s) prior to the specialist disposal in accordance with the Hazardous Waste Regulations 2005.
Small spills should be mopped up with tissue, allowed to dry off in a fume hood and disposed of via the contaminated waste system.
Large spills – up to 200ml ( up to the WEL for the room) , eliminate all sources of ignition, ventilate the room by opening a window if possible. Whilst wearing heavy duty nitrile gloves, lab coat and eye protection Proceed with clean up by applying an absorbent material ( vermiculite), sweeping into a bag with non—sparking implements. Waste materials should be disposed of as special waste through stores.
Larger spills – above 200ml ( above the WEL for the room). Eliminate all sources of ignition and evacuate the room. Call the fire Brigade to facilitate clean-up.
