In February 2004, our engine company responded to carpet warehouse on fire. Upon arrival our crew experienced a fully involved carpet warehouse fire. E-1 crew pulled a 2.5″ pre-connect line in the front bay door of the warehouse. My officer was donning his mask and I was flaking out our hose line when all of sudden we heard a high pitch sound. We looked into the bay garage door and we immediatley hit the ground. There was a 50 lb. propane bottle heading right at us. Several bystanders could not believe what they saw. We were very fortunate. The both of us looked at each other and continued our job… but with extreme caution.
