Recently our members responded to a reported structure fire in a private dwelling at 0130 hours. On arrival they had a fire in the attic of a one and half story frame dwelling. The Ladder Company was ordered to the roof to ventilate. During this operation as a member was operating the chain saw during the plunging process the blade suddenly became jammed. The chain stopped turning and became binded with what turned out to be a run of bx wiring cable.
Fortunately for the member the breaker to all electrical outlets and fixtures had blown earlier due to the fire. So he did not receive any electrical injuries. An inch or two to the left or right or higher or lower might have made a difference as to not catching this electrical cable running from floor to ceiling. The members completed opening the roof with hand tools.
I hope this experience can be shared with our brothers across the country and advise them to beware of something like this can happen.
