You might feel like you are doing a lot to ensure that any elevator in your building is working in the best way possible, and for the most part if you are getting maintenance done on a regular basis then this is true to an extent. With all of that having been said and out of the way, it is important to note that issues can often occur without you even realizing it, and this can lead to a lot of dangerous situations since many elevators reach some pretty high heights and if they were to stop then people would get trapped and at the same time they might just get injured in some way, shape or form as well.
What you need to do here is pay attention to signs that might indicate that any lift parts that you have working in your elevator are not working the way that they are supposed to. While monitoring lift performance is in and of itself something that can provide useful information, at the same time you might want to try using the senses that you have had from birth with smell in particular being surprisingly effective in this regard.
If you notice a strange burning smell or something that does not usually occur then some of the lift parts that are being used might be starting to wear down a little bit. Smell tests are really easy to do as well, all you really need to do is monitor the elevator shaft and breathe through your nose! Things like this can help you stay ahead of any potential disasters that might occur, as well as making it possible for the lift to continue working without breaking down.
