The bloke from British Gas who came to look, at a light fitting accidentaly broke the bulb , with bits falling all over the dining room table cloth .
I asked him if there was anything dangerouis in the bulb , to which he replied no .
After leaving , he returned and asked if i wanted him to dispose of the broken item .
I thought I remember reading somewhere that the broken bulb was dangerous - and with him returning , got me wondering .
I think when they first came out or made an appearance, the advice was not to dispose of in your general household waste nor the recycling bin.
Haven't found out why yet, might go and research it, but it would be google research though.
It's dangerous enough in quantity for the authorities not to want them to go into the general waste, but as folk here advise, the odd one should not be an issue.
i know they contain mercury, i remember reading something last year regarding these bulbs that when left on for long periods can emit cancer causing chemicals. i personally won't use them.
