What are EMFs?

Image result for magnetic or electrical fieldElectromagnetic Fields (EMFs) arise whenever electrical energy is used. We can find examples of EMFs all around us.  In our home from electrical kitchen appliances, from work processes such as radiofrequency heating and drying and even from radio, TV and Telecom broadcasting masts and security detection devices.

HSE: EMF Information




At the University

The potential for high levels of exposure at the University is limited. The Regulations require the University to ensure EMF exposure is below set Exposure Limit Values (ELVs).  This is achieved through the risk assessment process, identifying the potential for significant levels of EMF, then assessing the risks to which persons could be exposed, with appropriate controls then put in place to eliminate or mitigate the risk.

The University’s Property & Campus Services Department (PACS) is responsible for all electrical sub-stations and electrical infrastructure. Occupying Colleges, Schools and Departments are responsible for risk assessing any (potentially) significant EMF created by their own activities.

Examples of Controls

  • Restricted access.
  • Permit to Work to restricted areas.
  • Limitation for access for those identified at risk.
  • Location and limitation by distance from EMF source.
  • Work time exposure and work activity rotation.
