The startling alert came as health experts also warned that toxic mercury inside the bulbs can aggravate a range of problems including migraines and dizziness.
And a leading dermatologist said tens of thousands of people with skin complaints will find it hard to tolerate being near the bulbs as they cause conditions such as eczema to flare up.
The Department for Environment warned shards of glass from broken bulbs should not be vacuumed up but instead swept away by someone wearing rubber gloves to protect them from the bulb's mercury content.
In addition, it said care should be taken not to inhale any dust and the broken pieces should be put in a sealed plastic bag for disposal at a council dump – not a normal household bin.
None of this advice, however, is printed on the packaging the new-style bulbs are sold in. There are also worries over how the bulbs will be disposed of.~~~~~~~~~~
