hi, im just looking for a bit of advice. i rent a house and the back door has broke and wont open, my landlord is messing me about coming to fix it. is the back door being jammed shut a fire hazard?

It all depends on the layout and the travel distances, it could be a fire hazard, on the other hand it could be considered acceptable, without a lot more information I could not give a definitive response. Despite this, I think the landlord should repair the door so it is accessible for normal use, even if it is not required for fire safety reasons.
