Sorry about the delay in replying, been busy preparing for a trip to Uganda on Tuesday.
As always, lots of interesting discussion regarding safety testing. My initial question was does anyone know of any symbols that would be used on Class III medical equipment.
Given the situation in Ugandan hospitals, a new biomed is (very) likely to work in a hospital / department where nothing has been safety tested (since arrival in the country) and there's no record of what is and isn't working, so everything will need to be tested.
However, I have come across equipment which does appear to fall into the definition of Class III (often fake equipment from a certain Asian country), so it would be good if we could teach the students how to spot these and what tests to carry out on them.
As a slight side, we generally teach that it's a good idea to perform electrical safety tests every year as part of the PPM. Although there are more detailed guidelines about how often to perform a test in the service manual, these are often unavailable, so a one-size-fits-all system is probably best for now. Though we do teach them to check the manual where possible for more details.
