MDF craftwood contains formaldehyde and is known to cause adverse health effects in predisposed people. In some cases the allergic reaction may be quite severe.

The handling and use of MDF craftwood within the School must comply with safe Handling guideliness for MDF craftwood:


It is not permitted to store any chemical substances in domestic refrigerators in association with food or drink. It is not permitted to store any flammable substance in a refrigerator that has not been specially modified to eliminate the risk of explosion.

All refrigerators purchased for use other than storing foodstuffs must be modified prior to being put into service. The modification includes disabling the internal light and relocating the thermostat control unit to the outside of the refrigerator. These modifications remove the danger of contact arcs igniting flammable vapours.

This policy is retrospective to all refrigerators currently in service within laboratories.
