School laboratories are always full of challenge and new things happen to equipment and instruments. And one of main question usually students asked is that What should a student do if laboratory equipment is not working properly in the laboratory ?
This is a question that does not have one accurate answer and it depends on the laboratory policy and usually the first step is to report directly to the lab manager and supervisor then he or she will decide what to do! Do not try to fix any thing or use any method, because sometime some lab equipment are calibrate for a special purpose and all the process needed is to get it back to default option, so trust your manager and he is responsible for fixing or removing it from laboratory.
But if you did something to the lab equipment and that made it not working properly, this is your responsibility and you should be responsible for what you did with that equipment. But dont worry, usually there is an insurance that support students, or you can find a solution for fixing it with less cost and pass this condition
And always remember lab equipment have a guide book that you should study it and you can find it on the internet so you can understand how does that equipment work properly and have more chance to fix it, but remember, you should know about responsibilities of people in laboratory and schools and ask them to do their job for finding answer.
