On June 8, 2005, a decomposition reaction occurred in the manifold system on a mobile acetylene trailer at Western's Bellville plant that caused the fusible plugs of five cylinders to melt, releasing the products of decomposition. The materials released did not ignite before the deluge system was manually activated, controlling the incident. The incident started when a mobile acetylene trailer, with the cylinder valves open and the manifold fully pressurized, was moved into another bay and the block valve was opened, which initiated an acetylene decomposition reaction.
