fixed Wire Testing Healthcare UPS / IPS

Paddy J

Morning all, currently starting managing fix wire testing in the hospital that I work at – tester has explained they are not testing any UPS / IPS circuits supplied from the UPS / IPS (blue socket outlets etc. ) , he’s saying they never have to test these ( he confirms he wouldn’t know how). This leads me to ask what tests and how would these be carried out reference live functional testing  (earth loops etc.).BS 7671 says very little about this.

    Hm Mike, I think not. The IM systems are an essential part of operating theatres IT mains supplies, and the UPS derived supplies are life critical. It is essential that these checks and I&T are carried out by competent and trained people. These systems drive equipment like heart lung bypass machines and ventilators used for total life support. The Blue sockets are used for all the patient connected equipment so that they are essentially isolated from the surrounding extraneous metalwork, to prevent any possibility of electric shock which would be extremely serious if inside a wound or the body. Paddy, you need to contact John Peckham for further advice, but it may not be what you would like to hear. As manager of this process I hope you are qualified to understand all the technicalities of Electrical systems and installations, or if not are capable of assessing external contractors who are. There are few of these about, and assessment and quality control of the actual operatives is essential. It is a very responsible position with serious consequences if failure occurs.
