Aside from shipbuilding, dam bldg., high rise construction, and even bridge construction configured, among all other things...fatalities! I believe high rise construction is *one man per 1 million spent* As for the building of the GOLDEN GATE BRIDGE, Straus implemented the very first *hard hat* (actually leather design) and adapted a *safety net* precaution. However supervised neglect of the workforce request, resulted in multiple fatalities. The Carpenters/Iron Workers had complained of the insufficient *bolt* connection of the catwalk which suspended them from this very safety net. After two and one-half yrs. of a near *flawless* safety record...the bridge would assess it's toll. I can't recall this moment, but it was 10-15 men lost that day...and captured via a still image.
I remember some lame Contractor I worked for wanted me to, basically take a two-story plunge. Having two decades of experience under my belt, I said..."It's not safe, if your so insistant, put your bags on, get up here and walk the frail 2 x 4 member top chord truss, lacking proper bearing support" (Needless to say the wind was blowing 70 mph that day)
So if the Carpenters tell you it's not safe...then indeed...it is not safe.
