What to Do if a Glass Convenience Light Switch Containing Mercury Breaks
If a mercury-containing glass convenience light switch breaks in your facility, use the following procedure for clean-up.
Because most of the mercury contained in convenience light switches and ABS sensor modules is encased in metal capsules, the potential for a mercury spill to occur during switch collection is very low. However, precautions should still be noted when handling any potentially dangerous material.
All mercury spills should be cleaned up immediately. In general, small mercury spills on hard, non-porous surfaces can be cleaned up with paper towels and duct tape, and by ensuring that all material used during clean-up is sealed in a double plastic bag. This bag must then be disposed of properly, as directed by the municipal waste authority. Mercury spill kits are available at laboratory safety supply stores.
