I started thinking about this the other day when I was helping a friend fill a portable oxygen bottle. Another pilot came along and asked if we'd washed our hands, degreased the wrenches, etc. When I laughed he walked about 200' away to observe the impending fireball. I laughed because I have welded most of my life. I got started working in a huge aerospace factory as a weldor. In that plant there were literally thousands of bottles of industrial gases. All of which were changed on a constant basis by guys with a cigarette hanging out of their mouth. Tools were greasy, people were greasy, AND no one blew sky high. I had some time yesterday so I'm reading Aviation Safety. There on the front cover is an article about the DANGERS of refueling. Lots of warnings in the article about how an avgas fire can spread faster than you can run, how dangerous refueling is, etc. I was thinking about how many millions of cars, tractors, aircraft, etc. are refueled on a daily basis with seldom a problem. Only a pilots magazine could run such an article. Put that on the cover of Hot Rod and watch your subscriptions fall to zero. Last of course we have these forums where the second post of almost every topic is... "you are a dangerous fool and will surely kill yourself". This also seems unique to pilots. Post a video of you driving your car 150 MPH on some car forum and everyone will love it. Question is, while being safety minded is a great quality in a pilot, do we as a group take all of this too far?
