Identifying CCA wood before burning

[maxg]

Hello,
I've heard of chemicals sprayed on truck loads of wood at their arrival at the burning plant that reacted with CCA wood and changed its color to pink.

The truck load is refused if pink shows up during inspection. I've looked to find what is this chemical and haven't found one that could be use at a large scale.

Does something know what I'm talking about?

Thanks

mentions three chemicals for stain detection of cca-treated wood.

Thank you
I had already found those chemicals but they seam to be use on a very small scale. What I'm looking for is the specific chemical they use at the receiving of material.
