Life-Safety Renovation Check

Use this when renovation work exposes old dampers, rated walls, sleeves, access doors, or questionable existing life-safety conditions.

PrintableMobile-firstCopy-ready ask

Use when

You find an existing damper, rated wall, shaft, sleeve, access door, label, actuator, or penetration that looks missing, modified, painted shut, blocked, unlabeled, or non-compliant.

First move: document the as-found condition before touching it.

Field steps

Take a wide photo showing room/grid and how new work touches the old condition.
Take close photos of labels, access, sleeve/angles, actuator, blade path, paint, missing parts, or modifications.
Record what appears wrong without guessing legal responsibility.
Tell foreman/PM before tying in, removing, covering, patching, or repairing.
Ask whether AHJ, GC, engineer, PM, or RFI direction is needed.

Do not

Do not assume old work is acceptable because it was already there.
Do not assume you own the fix without scope direction.
Do not hide or tie into questionable rated/life-safety work.

Ask it clean

I found an existing rated/damper condition at [location] that looks non-compliant. Do you want photos and a scope note before we touch it?

Rule: TinnerFlow helps you check and ask cleaner. It does not approve work. Drawings, specs, manufacturer instructions, code/AHJ, employer policy, site safety rules, qualified-person direction, and foreman direction always win.
