The log the DHA asked for

Hand the broker a file

Camfil’s public page lists “automatically capture performance data required for regulatory compliance reports.” That is a CSV and a cover sheet, not a determination. OSHA, EPA, NFPA 660, the insurer — they asked who watched this housing on Sunday. This is the answer. It is not a DHA. Combustible status is labeled on file.

Blank hopper or air cells mean that optional sensor is not on the box. Do not fill them in. The 14-day Connect log is still on the floor.
