A school technical workshop wants to install 240volt machinery, (pillar drill) (belt sander)etc ,connected to the supply with circuit breakers in place. Does anyone know if you need an emergency stop button fitted as well to these machines ?
Cheers Campbell.

Definately Yes, in a previous incarnation I was in charge of 3 workshops for H&S and all machines needed emergency stops, remote and by the machine (i.e. kick-stop) and for certain high risk machines they should be key operated to enable restricted use.

Given that we are talking about a school environment, you might want to consider the following:
1. E-stop at machine
2. E-stop at isolation box (often on wall)
3. A master E-stop (all power, all machines) at teacher's post(s).
Having been an apprentice, I can see the need for a master E-stop (horseplay, inexperience, distraction, etc). Our machine shop had one and it was used a couple of times.

Posted By Ron Hunter This link may be of interest (PUWER faq) http://www.hse.gov.uk/services/education/faqs.htmBeware potential conflict between Emergency Stops and machine run-down times! I believe the HSE line on your question is "on the basis of risk assessment" - have a look at their education sector pages?

If machines like the ones you mention are likely to have run-on, then the motors can be fitted with electrical brakes (DC injection)when any stop is actuated.
