On July 5th, 1973 on the east side of Kingman Arizona, Andy Devine Avenue, just before 2pm, a railroad worker was offloading a railroad tank car to a side tank. The tank was filled full of liquid propane. (Doxal then, now Ferrell Gas.) The valve stuck. He tried to force it. He dropped his wrench and hit a valve. It sparked a fire. The fire grew. Because of its location it took a few minutes to get a call to the local fire department. Actually the fire station was just down the street within sight. It only took the FD just a few minutes to arrive. At that time the Kingman Fire Department was operated by volunteers. Don't let the term fool you, these men were well trained and experienced. They respond from all directions from wherever to they were to converge on the pumper truck. The railroad tanks have a safety valve that if the pressure gets too high it releases the contents at a controlled rate. The responding firemen knew this and were operating a rehearsed procedure they had actually practiced not too long before. The safety valve failed. The firemen soon realized that the safety valve was not working as it was supposed to and began an evacuation procedure. It was too late. There is a term Kingmanites of the era now know, BLEVE, Boiling Liquid Expanding Vapor Explosion. Of the dozen firefighter who responded, one survived. He was standing behind the firetruck at the time. For some it was instantaneous. Most suffered with agonizing burns for days. I believe the last to die was my High School principal, Lee Williams. He lived for 3-4 days from his burns. I believe some 50-70 others in the area were also injured. Locals were ferrying injured people in the backs of P/U trucks to the hospital. The local radio station was broadcasting pleas for locals to bring ice to the hospital. I believe the population back then was around 8,000-10,000.
