Practice question · Multiple choice
Safety procedures specify what to do BEFORE an experiment as well as during it. Why is the preparation stage weighted so heavily?
Hints
- Ask how much time you have to think when something goes wrong quickly.
- What determines the outcome once it has started?
Show the answer
D. Because most accidents remove the chance to react
Why
Controls have to be in place before the hazard is live. Knowing where the eyewash is has to happen while you can still see.
