I will derail this thread for my own ends
Having been lucky enough to start driving tankers quite young, I have seen many changes in the industry, “from couldn’t give a zb to very heavily regulated”
Now one of my pet hates is Health and Safety for the sake of it, like walking on designated routes to cross an empty yard, and wearing hard hats and hiviz while stood in an office. But the early days stories were told to me about how to find out if a load was hazardous. Drivers I worked with who had lots more experience used to tell me that when they cleaned a tanker out they would drain a bit out and if it burned when you put a match to it, they would take some home and run their cars on it, if it bubbled concrete they would give it to their wives to clean paths and sinks. If it smelt nice they would fill a bottle and use it as an air freshener
The ADR markings and Hazchem markings contradicted themselves until there was some liason with the various countries. In Europe there were also many variations of quantities and permitted routes. Some acids we used to carry were only permitted in 10 tonne maximum loads across austria. There were some products we carried to Germany which were banned from entering the drainage system, so we had to return to France or Holland to clean the tankers.
I have had to deliver a tank load of Cyanide to Baglan Bay, and before I loaded had to do a course which taught me to inject myself with an antidote. When I got to Baglan Bay, the bloke gave me a jam jar and a piece of string to get him a sample
In this case H & S did need to do something so things have improved, maybe a little too much with safety harnesses and companies banning you from the tops of tankers when you are loading, But they dont realise that you still need to climb on top to discharge or clean them.
I worked with one bloke who thought he knew better and went inside a tanker after tipping a load because the load had evaporated and was basically clean, apart from a couple of specks of black particles near the footvalve. What he didnt realise was the tanker had been loaded with a nitrogen blanket, an inert gas that keeps the product fresh and keeps moisture out. He climbed inside the tanker and was found 3 days later blown up like an old sheep He left 3 kids and a wife behind.
I have been burnt while tipping even though I was wearing all the safety equipment, at one point I looked like the singing detective In this incident it was a belgian driver alongside me who opened the wrong valve, instead of rushing off to the health centre I gave him a thick lug first, getting us both banned off site
I dont give a zb if i never see an orange plate again
