An explosion ripped through a plastics manufacturing plant. Dried and pulverulent wood had caught fire. This material was to be mixed with plastic materials to manufacture planks. Wood dust caught fire in a drier creating overpressure which lead to the explosion. A worker was killed by a metal pipe that was projected during the explosion. Numerous irregularities were found: sprinkler system in poor condition, fire hydrant broken and blocked in open position, malfunction of emergency exit lights, no “no smoking” signs and compressed acetylene and oxygen gas cylinders not secured. The plant’s operations were suspended, idling the 20 employees.
