Sequence decides the outcome
Most dry products can be swept or vacuumed cleanly while they are still dry. Once water is introduced, many of them change state: powders become paste, granules dissolve and spread, and anything cement-based begins to set. That transformation takes minutes and is not reversible, so the first response to a spill is the single most consequential decision in the whole task. Nothing else in a warehouse cleaning scope has that quality.
Writing dry-first into the scope removes the guesswork, particularly for a relief crew who may not know what is stored. It should be accompanied by a short list of products on site that must not be wetted at all, supplied by the client. The client knows their stock, and asking for that list at the walkthrough is quicker and safer than expecting a crew to read a torn bag.
