Lightning Protection for MOD Sites with Explosives Facilities
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.
