Congressional staffers may be used to putting out metaphorical fires. On Wednesday, they’ll get the chance to face off against the real thing.

The Office of Emergency Preparedness and Continuity of Operations is hosting its semi-annual fire extinguisher training for Senate staffers at the Maryland Fire and Rescue Institute Wednesday. The half-day seminar will be split between exploring the universe of commercially available extinguishers (dry powder, wet foam, compressed water) and physically combating an active threat.

“If you didn’t know any better before, you will learn to never spray water on an electrical fire,” an OEPCO aide assured HOH.

The class had been capped at 25 participants, but a last-minute cancellation means there’s room for one more “Backdraft”-obsessed staffer/closet pyromaniac to play with fire.
