An investigation is underway into the cause of a fire at the Martin Drake Power Plant Tuesday night.
Between 20 and 40 employees had to evacuate after the fire warning in Unit 7 sounded around 8:30 p.m.
The blaze is now out.
The fire department says these kind of fires are very serious because of the hazardous materials inside the plant.
Also, firefighters can’t use water to put a fire like this out.
No one was hurt, and no power outages were reported.
