Flash fire involving an LPG water heater mounted in a van
A worker in an oven cleaning business was using a gas appliance to clean oven trays. The appliance consisted of a water bath with an unsupervised burner below it. The flame extinguished. The worker tried to relight the appliance without allowing the unburned gas to dissipate and got caught in the resulting fire ball.
The actions of the worker will be considered under the HSE Act and the employer will be subject to a duty holder review. Energy Safety will look at the lack of flame supervision with the appliance as an appliance audit.
