 One Careless Mistake
I will never forget the night I was working at a Big Boy in southern Indianapolis, when the manage told me to do a real good job of mopping the floor that night, as she had gotten word the Health Department was going to evaluate us the next day.
Normally, we used sudsing ammonia for most cleaning jobs involving grease, like the grease traps over the grills, etc. Well, we also had a product called BK Powder we put in the dishwasher to sanitize dishes. It seems the BK Powder is a dry chlorine bleach. (I can hear the snickers out there, so I know some of you are well ahead of me.)
Not knowing any better, I dumped about two cups of BK into the mop water, which I had just poured a bottle of Little Bo Peep ammonia in.
in a matter of literally a few minutes, the building stood there, totally devoid of one human occupant. They had to call the fire department to open all the doors and use huge fans to exchange the air in the building before anyone could get to the mop water and dispose of it. Only then did someone explain to me that had inadvertantly mixed up a deadly poison gas that could have killed someone. I took the brunt of the gas that was produced, as I was the closest to the pail. They gave me oxygen, and checked me over, and I was okay. Needless to say, I will never again mix ammonia and chlorine unless I am trying to create a weapon.  |
