EMF Assessments

The Importance of EMF Site Surveys

At WG Safety, we specialise in offering health and safety, and environmental consultancy across the UK, from our base in Cannock, Staffordshire. As part of our services, we offer EMF site surveys.

An EMF site survey refers to an Electromagnetic Fields Assessment and highlights the level of EMF exposure in the workplace. Under the Management of Health and Safety at Work Regulations 1999, it is a legal requirement for workplaces that have a risk of EMF exposure to carry out these assessments.

The Control of Electromagnetic Fields at Work Regulations 2016 (CEMFAW) require an assessment of employees’ exposure to EMFs with reference to action levels (ALs) and exposure limit values (ELVs).

The Risk of EMF Exposure

An Electromagnet Fields Assessment forms an important part of the assessments carried out at work as part of the health and safety requirements. Electromagnetic fields are a type of radiation and too much exposure to EMF can lead to a range of sensory & health effects. This kind of radiation is common in everyday life, from the use of mobile phones, microwaves, Wi-Fi routers and more. However, the risk in these circumstances is usually negligible.

When it comes to EMF exposure in the workplace, it is your duty and responsibility to make sure there are no issues with over-exposure that can impact the health of the workforce.  Electric line installers, cable jointers, welders and electrical induction furnace operators are typical jobs that carry a greater level of exposure and therefore those employed in these roles are at greater risk of developing associated health issues. This is why it is vital to protect workers by carrying out EMF risk assessments of their tasks.

The Symptoms of EMF Exposure

It is also important for staff to be aware of symptoms of EMF exposure when working in environments that carry this risk. This kind of exposure could lead sensory effects such as nausea, vertigo, metallic taste in the mouth & flickering sensations (magnetophosphenes).

Health effects can include nerve stimulation, effects on the central and peripheral nervous system of the body: tingling, muscle contraction and heart arrhythmia. 

EMF Site Surveys at WG Safety

It is important to identify the sources of EMF in the workplace, which could come from equipment such as induction heaters, power generators, welding equipment and more.

Using calibrated field probes, in accordance with the HSE’s HSG281 Electromagnetic fields at work: A guide to the (CEMFAW) Regulations 2016, here at WG Safety, our surveys will include all exposure measurements, providing you with any necessary recommendations and information required to enable the formulation of an action plan for controlling EMF exposure.
