When I worked for the State/County, they decided to put them in public areas and I installed one in each of the buildings. The machine gives clear instructions verbally when activated. A person with training is certainly an asset when it is time to use one.
I asked the azzhat who was my supervisor to let me and one or two others get the official training to operate and maintain an AED, but he was an azzhat, ("it gives instructions verbally, anyone can do it, and they don't need any maintenance). I disagreed with him but what else was new .... (They do need maintenance to make sure the batteries are charging/charged up and make sure the paddles work, just another instance where he knew less about my job than I did but like a seagull on a chess board, he strutted around squawking knocking over the pieces and shittin on everything, and not having a clue to what was going on ...
One day we got a calll for one of the big a/c's at the 911 building not working. It was dispatched to me via the two way radios we had at that time by the office manger. The County Judge had a radio as he liked listening to the heartbeat of what kept his kingdom moving everyday.
Azzhat comes on and tells me, "be sure and check the outdoor ambient switch on that machine" trying to impress his boss, aka the Judge.
I relied, " no problem if it had one I would check it but that machine does not have one !"
Crickets after that ...
I worked onna big chiller for one of the buildings with a Carrier technician and we changed a valve that was bad in the refrigerant side of the machine, they have freon and chilled water, the water is what cools the building. Anyway this machine is as big as two pickup trucks and at the end of the day I took the valve into azzhats office and put it on his desk and sat down.
He looks up from his computer at me and then looks at the valve and then looks at me and says, "what is that?'
I tell him that is what was broke on the League City Chiller and not only do you not know what it is, you do not know what it does !
He sits looking at me and I then say, "and you want to tell me how to do MY job ?"
I loved poking that bear with a stick ....
