TAFE Question for I.T

What actions should take place to ensure that electrical equipment does not pose a risk to the workstation operator?
What would the answer be? After I thought it was “All electrical equipment should be switched off when not required” but is there any other answers to that question?
edit:
I don’t get this part, these two questions is abit tricky for me.
How often should eye exercises be performed when working long hours?
and
What equipment is available to improve view-ability of a monitor?
Answer #1
It’s basically Health and Safety when working with puters, you’ll find all the answers here, but most are common sense.
(Would do the looking for you, but off to bed as it’s 3.25am here ;?
