A technician weighed out 150 g of red phosphorus in a pyrotechnic composition used for fireworks within a bowl. A small quantity fell onto the weighing tray. When the technician picked up the material using a brass measurement spoon, friction caused the spilled product to ignite, followed by ignition of the entire bowl contents. The technician immediately removed the bowl from the shop space and extinguished the fire with the extinguisher found on the premises. The operating protocol was specified in greater detail; the cleaning step will be performed with a brush and wet cloth.
