Years of breathing lead based solder fumes, it was years before forced ventilation soldering stations were introduced.
PACE stations. I assume they've improved!
I recall a colleague being told he was being put on the new vacuum cadmium plant. As ever, it was delivered on a truck and left to the maintenance sparks to install it. No instructions, no training. Made a change from wiring kettle plugs though. Bob disappeared for few months, trying to work out what to do. When he reappeared one day, his thick shock of combed-back silver hair was two-tone. The new growth was a sickly yellow. He died a few months later. Natural causes allegedly. Aye, right. Everyone gave the plant a body swerve after that and I'm not convinced there were many properly treated high tensile bolts. Big earner for MoD though. Most of the work was repayment from industry.
