Yes, there was some advice from the MDA about using extension leads. It was quite a while ago and I can't remember the details, but try the MDA Web site - or quicker still, give them a ring !
Our electricians will not supply any extension leads for theatres, ICU, HDU, or anywhere there is a risk of liquid being spilt onto the sockets.
We have been working with a local engineering firm who have produced a small stainless steel "pod" on castors with double 13 Amp sockets mounted on the vertical sides and protected from spillages by an overhanging top. They intend to market this in the very near future, so if you would like me to get them to contact you, send me an e-mail giving your telephone number.(and your name etc ofcourse !)
It is CE marked, by the way.
Today is the day you worried about yesterday - and all is well !
