What Is Stairwell Pressurization Testing?

Stairwell Pressurization Testing is a process used to measure and verify that stairwells in multi-story buildings are positively pressurized to prevent smoke infiltration in the event of a fire. Proper pressurization ensures that occupants can safely exit the building through stairwells, even during emergencies.

TAB technicians use calibrated instruments to measure airflow, pressure differences, and fan performance. Testing identifies leaks, verifies fan operation, and confirms that stairwells meet design specifications and fire code requirements. Stairwell pressurization is an essential component of a building’s smoke control strategy and overall life safety plan.

Why Stairwell Pressurization Testing Matters

Life Safety

Positively pressurized stairwells prevent smoke from entering egress paths during a fire, protecting building occupants and ensuring safe evacuation.

Code Compliance

Many building codes, including NFPA 92 and local fire codes, require stairwell pressurization testing for new construction, renovations, and major building modifications. Failing to meet pressurization standards can result in failed inspections, costly rework, or delayed occupancy.

System Efficiency & Reliability

Testing identifies leaks, fan performance issues, and airflow imbalances. Addressing these issues ensures that stairwell pressurization systems operate efficiently, minimizing energy waste and equipment strain.

Documentation & Reporting

Our TAB-certified technicians provide detailed reports documenting airflow readings, pressure levels, and system adjustments, providing building owners and code officials with reliable verification of compliance.
