Damage Control (DC) Repair Party Leader Practice Test

Electrical damage is indicated by ED. This marking quickly tells the crew that the affected area or equipment has electrical system damage, guiding actions like de-energizing circuits, isolating power sources, and prioritizing electrical repairs to prevent shocks or further faults. The other markings correspond to different hazards—CHM for chemical damage, TOX for toxic exposure—and a plain E isn’t a standard symbol for electrical damage in this notation system.
