This from Steve Redick:

Took this in about 0515 Thursday. Very tough to get any decent images, the L tracks and heavy smoke covered the front. The one view of the rear and upwind was decent but badly arcing wires kept me from getting too close. It was a plating company so haz mat protocols were in place with some local evacuations. Nice to see the new TL5 working. TL10 had an old HME spare and operated very sparingly.
 
All the images can be seen here:
