Electromagnetic exposure

Assessing risk and achieving compliance

The EMF (Electromagnetic Fields) Directive 2004/40/EC requires employers to assess the risk to their employees from exposure to electromagnetic fields. 

Dependent upon the types of electrical systems in use, an organization may be able to comply through a simple risk assessment. Alternatively, they may need to carry out more extensive work involving site surveys and technical assessment. 

How we can help

We have the expertise and experience in both risk assessment and electromagnetic fields to guide organizations through the process in the most cost-effective manner, whilst ensuring that the necessary steps are taken to ensure compliance. Our services include:

  • Checking electromagnetic field levels for compliance with human exposure limits
  • Assessing EMF compliance of systems via analysis, calculation, modelling and testing
  • Preparing EMF safety assurance strategies and plans to ensure that systems are compliant and that safe working practices are in place
  • Assessing the impact of EMF regulations on equipment design and operation
  • Specifying, managing and/or performing EMF testing activities

What are the benefits?

  • Compliance with European directives
  • The ability to develop realistic and effective solutions through an in-depth understanding of potential electromagnetic problems
