Fluorescent light bulbs contain a very small amount of
mercury equivalent in size to the tip of a ball
point pen. Although small in volume, this is still enough to pose
an exposure risk and requires special handling. When bulbs are
intact or in use no mercury is released. It is only if they are
broken that there is a risk of vapor exposure.
(Beware: when they break it is like a small
explosion and results in many tiny glass particles and powders
which tend to spread out over a wide area.) The US Environmental
Protection Agency recommends specific clean-up and disposal
