1956$ROOT: [TECH_CENTER. INCIDENTS] 82__3_RC.DES;I 82_3_RC * Ti and Dry C12 Fire in Wet Compressor A wet compressor was destroyed by a dry chlorine-titanium reaction. The ; pressor went into high vibration following a water wash when the water to the suction side, was shut off due to an operating error. Dry chlorine entered the titanium compressor. The impeller and part of the case were consumed by the chlorine-titanium reaction. Flow reversal caused charring of 40' of the 20" FRP suction piping and the suction valve. Total property damage was $140M. 195 6$R00T: [TECH_CENTER.INCIDENTS]82_4_SAF_RC.DES;1 82_4_SAF_RC * H2 Fire in H2S04 An audible reaction, accompanied by momentary flame, occurred in the vicinity of a small hole in a wastewater pipeline when the pipe was heated to weld a patch to repair the hole. The line had been temporarily used to transport waste sulfuric acid during a plant shutdown. The line was not flushed prior to welding and contained a hydrogen-air mixture. A 1000 gallon spill of epichlorohydrin was cleaned up using a vacuum truck. Shortly afterwards it was noticed that a reaction was occurring in the truck. It was found that a previous leak had allowed caustic into the ditch where the EPI was spilled. Investigation pointed out that the possibility of reactive chemicals incidents from less than obvious sources must be con sidered before vacuum trucks are loaded. Note also that the vacuum truck in this incident had no relief device. 1956$ROOT:[TECH_CENTER.INCIDENTS]83_32_RC_EF.DES;1 83_32_RC_EF * MagMeter Explodes It was recently reported that a Fischer-Porter mag-meter exploded while in service. The meter, which was supplied with an aluminum case, was in acid service. Apparently acid leaked into the alu minum case and generated hydrogen. Similar meters in the af fected plant have been supplied with a nitrogen purge. New i callations will use F-P mini-mags, which have remote electronics. do 071974 CONFTDENTTAl 1956$ROCT: [TECH_CENTER.INCIDENTS] 83_33_RC.DES;1 83_33_RC * Reactive Chemical Incident in Lab A caustic operator, after finishing his routine analysis, was c aning up around his lab bench. He was emptying his caustic samples into the sink drain with a flow of hot water. He picked up an unmarked sample of sulfuric acid and dumped it into the same sink containing caustic. 1956$ROOT:[TECH_CENTER.INCIDENTS]83_34_SAF_RC.DES;1 83_34_SAF_RC * Low 02 Content In Vessel A bizarre tragedy occurred in a Ludington, Mich. A MgCl2 evaporator was down for maintenance. Low 02 content in the body caused by depletion of 02 in the air due to rapid rust formation on high surface area, clean steel tubes, led to a fatality. Give this wide publicity and let's be sure we have no similar traps awaiting us. DO 071975 CONFIDENTIAL
