10/4/2018 FROM PAINT BOOTH SUPPLIER: RE: Section 11‐20‐04, Tag # 17 & 18. This piece of equipment is called a sanding, grinding and paint booth. We are concerned and need to be sure that the grinding mode will not cause sparks. If there would be still wet paint or primer in the filters and then a spark was introduced to this filter media, and explosion and fire would be imminent.

Please confirm there will be zero chance of sparks created in these booths.

Sanding and painting will not take place at the same time. The sanding is for fiberglass parts. There should be no metal grinding in the fiberglass booth.
