Lightning Protection for MOD Sites with Explosives Facilities

  • 8 available

Course summary

This course will give you a comprehensive overview of lightning protection for Ministry of Defence sites that contain explosives facilities. The course explains the lightning protection and earthing requirements of Joint Services Publication JSP482 and gives examples of how to protect explosive facilities to the British Standard BS EN 62305.

You will gain a thorough understanding of the design, maintenance and compliance testing of lightning protection systems, with particular reference to buildings containing explosives, illustrated with case studies of both good and bad practice.

The course includes a lightning protection workshop in which you will be able to discuss your own projects and problems with the expert team and your fellow delegates.

Why attend?

  • Gain vital safety knowledge in protecting sites with explosives facilities
  • Understand the regulations for such facilities including JSP482 and BS EN 62305
  • Prevent devastating damage to buildings and critical assets
  • Design effective protection for a range of assets based on risk analysis
  • Update your knowledge on the latest developments in protection and earthing technology
  • Create a safer environment
  • Share best practice from facilities around the world
  • Network with peers, reviewing your own installations and issues

Excellent, would now feel confident to do risk assessments and design LPS for relatively small-scale installations I work on.

Good course well delivered. Perhaps a bit much information for 2-days. Fantastic facility.

Jake, 26-27 October 2022

An informative and technical course delivered by an excellent lecturer. I feel it would benefit from a hard copy of the handout to help the delegates.

Grant, 26-27 October 2022
