I remember a conversation about various machinery exhaust fumes.
And, carcinogenic substances involved in construction and transport.
Asbestos being one of the more dastardly.
There was an electric loco in the USA which had an oil bath transformer.
Cleaning that proved to be very carcinogenic for maintenance staff.
BUT, I was told that of all the chemicals, including those in exhaust fumes, the WORST found on weasels was Aflok (not sure how to spell it being a company title).
Pink coloured Aflok had heaps of heavy elements in it to prevent corrosion in the loco donk water cooling supply.
Part of loco prep was to open the water tank level sight gauge to drain out the sight glass.
Then shut to view the water level appear to ensure sufficient water supply existed.
So, we got it on our hands every day.
I guess that with any technology, there will always be something which later proves to be nasty.
Leaded paint, leaded petrol, DDT, and so on.
BUT, as to weasel exhaust fumes, GOTTA LUV Aussie Alco black plumes erupting from the exhaust stack.
Honorary soot belchers.
Just hold year breath when it stomps past.
Steve.
