Approval record: Upstream
Buyer records the hood schedule, simultaneous combinations, material information, quantity, destination and optional budget. If protection design is still open, the approval packet should say that a material assessment is required, not that this website has already classified the dust. Drawings can be exchanged after contact because the inquiry form has no upload control.
Control boundary
Compare who supplies isolation, discharge controls, monitoring and outdoor connections where the assessed design requires them. Put those responsibilities on the same scope drawing as the ductwork. Connected load, three-phase supply, compressed air demand, PLC interface and footprint must match the pad you actually have. Working pressure of pulse air is a supplier confirmation, not a copied catalog bar value.
