On a basic level, electromagnetic fields (EMFs) are invisible areas of energy and a form of radiation. EMFs are produced wherever electrical equipment (including computers and mobile phones) is used. They are present in virtually all workplaces, and with most electrical equipment, these EMFs have no discernible effect on people.
However, in some cases, electric equipment can create electromagnetic fields that are of a high enough level to cause harm, at which point employers may need to take action.
WHAT TYPE OF EQUIPMENT CAN GENERATE POTENTIAL HARMFUL EMF LEVELS?
Examples of the types of equipment which may generate potential harmful EMF include:
WHICH BUSINESSES ARE LIKELY TO BE HIGHER RISK?
The harmful effects from EMF are very rare and don’t happen in most day-to-day situations at work. There are some business sectors in the United Kingdom (UK) where the risks are higher. These are:
PEOPLE AT RISK
Employees at particular risk include those who have informed you of any condition, which could mean they are more susceptible to the effects from EMF exposure. This includes those who:
WHAT LEGISLATION COVERS EMF?
The Control of Electromagnetic Fields at Work Regulations 2016, known as the CEMFAW Regulations, apply in England, Wales and Scotland.*
*In Northern Ireland The Control of Electromagnetic Fields at Work Regulations (Northern Ireland) 2016 apply.
There are very few circumstances when the Regulations do apply. These circumstances are set by the Health and Safety Executive (HSE).
EMF is a complex and technical area. To find out more about EMF visit The International Commission on Non-Ionizing Radiation Protection (ICNIRP). This independent organisation provides scientific advice and guidance on the health and environmental effects of non-ionising radiation.
In the UK, the HSE provides guidance to employers in the free publication Electromagnetic fields at work: A guide to the Control of Electromagnetic Fields at Work Regulations 2016 (HSG281).
In Northern Ireland, the Health and Safety Executive Northern Ireland (HSENI) provides guidance – see their publication Electromagnetic fields (EMFs).
