Inquiry #26: With regard to the blast booth specification (133426B(1), page 324:

1. Is the blast & recovery unit (133426B(2), page 325) a closed circuit unit or an open blast unit?

2. The last paragraph on page 324 and as well as the exhaust fan section (133426B(3), page 325) seem to describe a paint booth type exhaust/ventilation system.
