Working in a coal mine - 12

I looked around for the supports inside the outer steel container that I had been told were there. And they were! So I delved into my backpack and pulled out the profiled dishes which I had had made.

It was hot and it was very humid. Inside the box - steel container - it was even worse, but then the transformer had been working until a short while ago.

I put my containers in place, then I tipped in measured amounts of blue silica gell.

As quickly as possible I bolted the top back down.

“Now we have to wait.” I said.
