ace Posted December 1, 2009 Share Posted December 1, 2009 Hi Guys, I am working in a venue where I am PAT testing the lighting fixtures, but I am unhappy with the placement or size of the safety bonds which have been put on the lanterns. Although the fixings for the lanterns are good, the nearest appropriate placement for fixing secondary suspension is a steel bar 1m above the fixtures. I am therefore looking to source 2m safety bonds. Can anyone recommend where I may be able to order these from off-the-shelf? Or will I have to have them made up? Also what SWL ratio is appropriate for the safety bond on a lantern? Many thanks, Chris Link to comment Share on other sites More sharing options...
dunk_1984 Posted December 1, 2009 Share Posted December 1, 2009 I would think a call to Stage Electrics would solve your issues, not necessarily the cheapest, but that's relative. You need a bond rated at or above that of what it is supporting. They are rated at 10x their list SWL to allow for shock loading. Link to comment Share on other sites More sharing options...
jimbo7744 Posted December 1, 2009 Share Posted December 1, 2009 Chris, What is the primary means of suspension for the lanterns? An existing metal bar, plasterboard ceiling with metal or wooden battens, brick and mortar wall or other? Just asking and not teaching you to suck egg's, but before you spend a large amount of money on custom and very long bonds, not all applications do require secondary safety bonding dependant on the fixture/ease of access/regularity of movement or refocusing/weight etc. Unless your establishment require this under their health and safety policy.

TomHoward Posted December 1, 2009 Share Posted December 1, 2009 I bought some very cheap 800mm 35kg bonds this morning, if a single span would suffice (and reduce the load accordingly) - if it's only for cans etc. Link to comment Share on other sites More sharing options...
GridGirl Posted December 1, 2009 Share Posted December 1, 2009 I've always found Rope Assemblies to be helpful and usually pretty competitively priced. Link to comment Share on other sites More sharing options...
Tomo Posted December 2, 2009 Share Posted December 2, 2009 As to ratings, if the item is sold as a safety bond, then the rating plate on it is the maximum weight of fixture that it can be used for. The strength ratios are already worked out for you before they apply the rating plate, so there is no need to further derate. Link to comment Share on other sites More sharing options...

I heartly agree with Grid Girl, Rope Assemblies are ace and will make up whatever you want and will be much cheaper than Stage Electrics. Link to comment Share on other sites More sharing options...
Andrew C Posted December 2, 2009 Share Posted December 2, 2009 You may be right in the need for a bond, but that question is not part of a PAT regime. Flag your concern with management by all means, but it is their problem to sort it out! Link to comment Share on other sites More sharing options...
