I have been doing HVAC type work since 70s and Freon and Refrigerant chemical always came in color coded pressurized containers .
It was always easy to tell from a distance R12, which was white R 22 which was Green R 502 which was Purple Etc. Etc. even as new refrigerants cam on market they had there own colors or banding and could be easily known what it was . Especially after they have been sitting for long periods tucked away in warehouses and been in service trucks the labels can wear off but the paint never did.
But that's all gone away .
Tanks are now coming out in Generic White and that can lead to serious issues when a technician grabs the wrong tank because they misread or mistook the label for what a product is and belive me those of us with Dislexia have a hard enough time as it is with labels.
Putting the wrong refrigerant in a system will damage and kill the unit. When labels wear off tanks will not be able to identified with out sophisticated testing leading to tanks with virgin product being sent back for recycling and refrigerant wasted.
hazmat teams will also now have to take even further safety precautions because they now will not know whats in a tank if label is missing they will not have a clue what they are dealing with
Generic White Tanks are a very bad idea.
