Stabilize the room before opening the assembly
Contents are moved from the affected zone when this can be done without passing beneath unstable material. Floor protection and containment prepare for water or insulation that may fall during access. Openings are planned at useful locations rather than spreading demolition across the whole ceiling.
Wet insulation and damaged ceiling board are evaluated for safe retention. Framing and other stable layers can be dried after the source stops and sufficient access exists. If wastewater from an upper fixture is possible, the category is resolved before handling begins.
