93. If a major flareback occurs to a boiler, which of the following actions should be immediately taken?
A flareback is caused by burning fuel; therefore, the immediate action is to secure the fuel to the burners. This stops combustion and mitigates the hazard. Securing ventilation or the forced draft fan prematurely can increase the risk of explosion by allowing unburned fuel to accumulate, and purging is a subsequent action.
