Working in a lab

Working in a laboratory is different from working in an office. Some of the rules that apply when working in or around a laboratory are given below.

You will find the information under your Faculty tab.

When you start working in a laboratory, you have to take notice of several requirements beforehand. This is not only about the materials you are going to use, but also legislation and internal regulations. The section 'Laboratory general' describes all preparative actions you have to take and all background information you need before you can start experiments, like doing a risk assessment and thinking about the necessity of permits or selection of the right type of safety gear. The section 'Working safely with...' is about the actual risks and how you can deal with those in your laboratory.
