Hi everyone, came across this forum whilst looking for regulations on fire exits but all the documentation fried my brain and left me not much wiser really. I need to find out how far away from a fire exit you can have an obstruction externally. We have a fire exit door from our commercial premises and we need to install an oil tank outside the building, we have been told my a plumber that we are ok to install an oil tank in the mentioned area but I wanted to clarify before we go ahead with anything. As soon as you're out from a fire exit, how many metres, if any, have got to be left as a clear path? I'm in Wales if that makes any difference. Any help would be greatly appreciated. Thanks in advance.
