I'm working on an incident in an aerosol manufacturing facility. The following question has nothing to do with the incident. However while doing a quick walk through from the incident area, I noticed a bonding/grounding technique, that I believe isn't correct.
The company uses the clamps from battery jumper cables as the attachment device between portable tanks containing Class 1 flammable liquids and the building. If I recall correctly somewhere I have read/seen or been told these are not an acceptable method of bonding/grounding in a class 1 div 1 atmosphere.
I have looked in numerous locations to include NFPA 77 specifically annex G, I see nothing that leads me to believe the jumper cable clamps are an acceptable attachment device is this conclusion correct? However I find nothing that states it isn't.
I'm convinced I have read somewhere this isn't acceptable.
