Electromagnetic Equipment Risk Assessment

Hazards

Hazards associated with electromagnetic fields are:

• exposure to magnetic fields, which can cause biological effects, although the nature of such effects is subject to debate, as research is at a comparatively early stage

• interference with cardiac pacemakers, which can lead to their malfunction

• use of cryogenic liquids to cool large magnets — often there is an outer jacket of liquid nitrogen and an inner coolant of liquid helium.

Persons at Risk

The following are at risk from electromagnetic equipment in the laboratory.

• All laboratory staff.

• Cleaners.

• Visitors.

Risk Rating

The risks are as follows, as given under guidance in BS 8800.
