Input: Text: i just started at the ymca as a lifeguard and my first shift was the closing shift last night. i had been shown once how to turn off the steam room, by going into the room with all the pool pumps and just flipping a switch on the wall. it was the end of the night, around 8:30 and everyone was assigned to their cleaning duties. i had to organize the life jackets and one of my coworkers had to clean the steam room with bleach. i finished my job and was instructed to go turn off the steam room (the steam room turns on every 10 minutes, and she had just started pouring bleach around the room after airing out the room). i headed back to the pump room to turn the steam off, but apparently someone had already turned off the steam. i proceeded to flip the switch the other way and walk back out to see what other work i needed to do, and when i walk out, the girl who was cleaning the steam room is sitting on the bench coughing as another coworker is sitting next to her. i rush over, and ask what happened and she tells me "the steam came back on and all of the bleach steam blasted into my face". i felt horrible and immediately apologized, and she wasn't too upset, as it could've gone a lot worse. didn't even have to fill out an incident report. but still, could've gone a lot worse. gonna be an awkward next few shifts.

TIFU by almost killing my coworker and losing my job on my first day of work by accidentally turning on a steam room filled with bleach.
