In August 2022, a worker in a cafe kitchen suffered burns when an aerosol can of cooking oil was inadvertently dropped into a deep fryer of hot oil.
The aerosol can had been placed on a trolley next to the fryer. The worker had been working near the deep fryer and the aerosol can fell into the deep fryer without her knowledge. The worker walked past the fryer just as the aerosol can ruptured and was burnt on the face and neck. Aerosol cans store contents under pressure. In this case the heat of the oil in the fryer was sufficient to cause the rupture of the aerosol can.
A similar incident occurred in 2010, when an aerosol can of cooking oil exploded, injuring two chefs.
The aerosol can was placed on the kitchen work bench next to lit gas burners. The propellant inside the aerosol can heated up and expanded. The base of the can blew out, releasing the propellant which was ignited by the gas burner resulting in an explosion. Both chefs received flash burns to their upper bodies, and a large window at the front of the cafe blew outwards.
