How to Clean Up a Broken Low Energy CFL
In the event of an accidental breakage of a CFL, normal good housekeeping is required.
Take care to prevent injury from broken glass.
Vacate the room and keep children and pets out of the affected area. Shut off central air conditioning system, if you have one.
Ventilate the room by opening the windows for at least 15 minutes before clean up.
Do not use a vacuum cleaner, but clean up using rubber gloves and aim to avoid creating and inhaling airborne dust as much as possible.
On hard surfaces sweep up all particles and glass fragments with stiff cardboard and place everything, including the cardboard, in a plastic bag. Wipe the area with a damp cloth and then add that to the bag. Household cleaning products should be avoided during clean up despite the very small amount of mercury involved. See the next section for cleaning carpeted surfaces.
Use sticky tape to pick up small residual CFL pieces or powder from soft furnishings and then add that to the bag.
The plastic bag should be reasonably sturdy and needs to be sealed, but it does not need to be air tight. The sealed plastic bag should be double-bagged to minimise cuts from broken glass.
How should I clean up if I have broken a CFL on carpet?
As mentioned earlier, the amount of mercury contained in a typical CFL is very small, up to 5 mg and is unlikely to cause any harm to human health. The level of risks involved in the case of a broken CFL on carpet is no greater than that on hard surfaces, although it may take a longer while to clean up the affected area due to the nature of the carpet surface.
The above clean up procedure should apply, but minus wiping up with a damp cloth and more attention should be paid to residual CFL pieces or powder removal using sticky tapes.
How should I dispose of the CFL waste?
The bags can then be discarded through your local council. All local councils have to make arrangements for disposing of hazardous household waste. Many local authorities have a special place for hazardous household waste at a civic amenity site or household waste recycling centre. The National Household Hazardous Waste Forum runs a website with details of these centres for chemicals, but which also applies to other hazardous wastes.
