Inquiry (采购产品): burst discs in ansul extinguishers we had been advised by service depots to put burst plate discs in our portable ansul extinguishers, especially those in high vibration service e.g. field trucks, compressors etc. now we are hearing that Ansul is advising against this as there have been cases where the rupture disc obstructs the nozzle causing problems. Can you provide some direction on this, are there any formal bulletins etc that I could pass on to our field areas?? Also, are there any bulletins regarding whether to mount the portable 30 lb extinguishers vertically or horizontally (i.e. elbow & hose to upward side) in high vibration applications **** Hidden Message ***** Dave Sitar PO box 38 112 - 4th Ave SW Calgary, AB T2P 2V5 CAN Company: Suncor Energy Inc.
