I am a engineer by trade, so have been around all sorts of dangerous machinery, in factories, construction, farming, railway etc., been to many seminars and meeetings on H&S and still I have the odd lapse in safety occasionally though not intentionally. I am far more concious of safety now but what others do sometimes frightens me to death. Silly little things sometimes, like my wife put three boxes against the inside of the front door, she didn't understand when I complained that we could not get out quick if there was a fire, response was "I put them there so I wouldn't forget to put them in the car tomorrow"
