I stay in an apartment. Recently there was a power failure, and some of the residents got stuck in a lift. So we hired a licensed electrician by contacting an electrical service provider. He arrived within half an hour and did all the things to make the lift work. Finally, the lift started working, and the residents were able to get out of it. After that, he did a thorough check-up and examined it. He told us that there is a breakage in some electrical lines and needs to be repaired. Finally, he repaired it on that day. All the residents were so thankful to him for taking a lot of effort to fix the issue and save the residents' lives by finding out a quick solution to make the lift work. Can anyone please list out some safety measures to be undertaken if such a situation arises in future?
