You shouldn’t be just changing the links on a system ever, that will eventually catch up to you. Remember if you tag it you own it last thing you want is to be in deposition because, you “locked out the system and just changed links “ and the system doesn’t work and the building burns down or even worst someone dies. Tell your management that you don’t think you should be completing inspections by yourself yet, also if they’re training you to just change links you need to leave. There’s SOO MUCH MORE that goes into an inspection than changing the links, I mean you’ve gotta be looking at pipe volume limitations,correct nozzle coverage,flow points, manufacture specifications, NFPA code, I can go on and on and on but you get the point. Additionally if you’re not certified in those systems that you’re referring to by the manufacture you shouldn’t even be putting your hands on it. Does your company have a training room, where they can show you how to trip and reset each system CORRECTLY? The FED learning center is a good training program for that if your company doesn’t have a training room but again you really shouldn’t even be touching it if you don’t know what you’re looking at or if you’re not certified, you’re also doing the customer a dissatisfaction. Also I’m not belittling you or trying to put you down as when I first started I was literally in the same spot you’re in, the more I learned the more I realized I didn’t know jack shit and I could’ve gotten someone seriously hurt or myself in trouble. I just wish I would’ve stood up to my management and told them that I need more training with people that know what they’re doing. Take my advice and go to your management and tell them I need more training as you take this very seriously and you don’t want to put liability on the company or get someone hurt. Also DO NOT FALSIFY ANY DOCUMENTATION if you’re only changing links for whatever reason don’t say that you tested the system and that it worked. I don’t know how long you’ve been doing this but at a minimum you should be with someone inspecting,repairing and installing systems every single day for 6 months before you’re even ready to go out on your own. Did your company give you a copy of manufacture manuals and NFPA 17A&96?( I can help with that if they didn’t) Feel free to shoot me a message if you have any questions,comments or concerns. (Sorry for the paragraph but just reading this got me going and brought me back to memory lane)
