I definitely fall into the high risk category, but since part of my work can create mustard gas fumes, I used to smoke, I spend a lot of time stuck in traffic jams, or in cnc shops where the oil mist literally glues itself to any surface, my partner smokes, I work on vehicles, around c02 plants, up ladders or on trucks on windy days, I carry around 50kg of refrigerants, oxypropane, nitrogen, acetone, butane canisters.
Electric shocks are not unfamiliar, same with both heat burns and refrigerant burns. I fairly regularly work on "bomb test range 2 or munitions test bed 3, or have to retreat to a blast shelter in a quarry, fork lift trucks or reach trucks are a daily encounter, as are manuevering tractor/trailors, compressor swaps on a main road, or in foundries, climbing about in rafters or on cable ladders. High voltage electrical supplies, very high pressure gasses, never mind 30000 miles a year on Britain's road networks.
When you take all that into account, I really dont see that this requires all the fuss thats being attributed to it.
