In the courtyard of a facility producing and trading magnesium powder, an explosion followed by fire occurred at 2:25 am in metal waste stored in bulk at an outdoor zone. The previous afternoon, an employee had stockpiled on this same 2-m³ storage site cleaning wastes (i.e. magnesium pellets and dust) and a ripped bag of lime so as to package all contents into a single big-bag. By the end of the day, this operation had still not been completed and the depot was abandoned as is.

The explosion damaged a neighbouring facility; given the late time, no one was injured.

According to one of the hypotheses forwarded, rainfall early in the evening on the waste pile could have triggered the formation of hydrogen, with ignition being initiated by a lightning strike. These wastes should not have been stored under such conditions; inspectors noted all the facts.

Following the incident, the facility operator was required to adopt several measures, i.e.: remove cans and big-bags of waste from outdoor exposure; replenish the stock of magnesia (substance used to extinguish this type of fire); monitor the stockpile that continued to burn; clean the adjacent rainwater outflow grating in order to avoid puddle formation.
