The employer’s assessment of the health implications of electromagnetic fields must factor in any active medical implants that their employees have in so far as these have been reported to the employer. The table below illustrates the estimated risk of interference to active medical implants in different jobs:

Factoring in workers with pacemakers

It is the employer’s duty to carry out an assessment of the impact of electromagnetic fields on the health and safety of their employees and especially any workers who have a pacemaker and who need to operate or work in the vicinity of the following kinds of equipment:

• demagnetisers
• welding equipment
• induction heating equipment
• metal detectors
• microwave dryers
• high-frequency heaters
• electric generators and motors
• electrochemical process equipment
• electric drills and other power tools
• powerful aerial transmitters
• powerful static magnets (magnetic resonance imaging equipment), and
• high-voltage devices.
