I have never understood the Fire Brigades refusal to accept just what people, even the disabled, are capable of doing, when the flames are licking at their arse.
The world is not made up of large areas of safety around every potential hazard, nor, in an emergency, will people respond in the manner recommended, no matter how many "training " sessions, "drills" and notices are paid for.
Too much "Consider what if" training for too many "officials" who ~ and let's be honest here ~ if they had much in the way of sense, wouldn't be in the job in the first place.
