Someone wants me to cut into a live or pressurized duct system

Cutting, Holes, Openings & Field Modificationsred

Stop and verify. Cutting into a running/occupied system is not a normal “just cut it” task. It needs foreman direction and usually building/operator coordination before the cut.

Open in Field Rescue Open category

Field checklist

Confirm whether the system can be shut down.
Identify what the system serves and whether the building is occupied.
Document the cut location, airflow, access, and risks.
Ask what containment, timing, and approval are required before cutting.

Ask foreman

This duct appears to be live/running and serves [area]. Before I cut, who is approving the shutdown or live-system procedure?

Do not

Do not freelance a live-system penetration, cut blind, or assume “the building engineer said it” replaces your foreman’s direction.

Why it matters

Live-system work can affect occupants, controls, pressure, dust, safety, and building operations.
