Wadda you mean you old people!
Just kidding when I started working 50 years ago there was no safety..period When films like these started coming out they were laughed off nobody took safety seriously.
One of my first jobs was clearing trees and bush for a survey crew crew, picture 16-17 year old's with chainsaws wearing cutoffs and flip flops cutting down 24" diameter trees no muffs, no ear plugs, no instruction.
Syncrude used a movie called doctor death to illustrate the dangers of H2s the whole room cheered and laughed somehow the message got lost.
When you watch the attached video how many safety violations do you see by the boss ?
