It appears there are procedures for cleaning up an energy saving light bulb if it breaks. A Government department has said that if you do break one you should leave the room for at least 15 minutes. Apparently this is because the mercury inside the bulb can cause problems such as migraines and dizziness. The Department for Environment has said that a broken bulb should not be vacuumed up but should be swept up by someone wearing rubber gloves. It should also be put in a sealed bag and disposed of at a council dump rather than in a household bin. Is this an example of extreme government regulations or are these light bulbs actually toxic?
