In April 2009 it became illegal in the UK to use mercury in any thermometers or sphygmomanometers meant for sale to the general public, but sales to professional users were allowed until April 2014. Whilst using devices containing mercury remains permitted, it's essential that professionals are aware of the risk to health from damaged units, and the correct disposal methods.

• Exposure to mercury can have serious toxic effects
• Care should be taken when handling, storing and transporting devices containing mercury
• All areas where mercury is present should have an easily accessible spillage and disposal kit
• Damaged or obsolete devices that contain mercury should be disposed of by a licensed waste carrier
