When most people think about building fire protection, the first thing that comes to mind is smoke detectors and evacuation routes. While these are certainly important, another key element of fire safety is stairwell pressurization.
In this blog post, Archangel Alarm Services, LLC will take a look at stairwell pressurization and some of the basics you should know. We will also discuss some benefits of having a properly functioning stairwell pressurization system for building fire protection. Keep reading to learn more!
What is a Stairwell Pressurization System?
A stairwell pressurization system is designed to prevent smoke and other products of combustion from entering a stairwell during a fire. The system does this by maintaining positive pressure in the stairwell, which prevents outside air from entering. The system is made up of several components, including:
- A blower unit that provides the airflow
- A control panel that scans and controls the system
- Smoke detectors that activate the system
How Does It Work?
The key to a properly functioning stairwell pressurization system is ensuring there is sufficient airflow. The system must provide at least 0.10 inches of water column pressure difference between the stairwell and the surrounding area. This is typically achieved by having the blower unit provide 100 cubic feet per minute (cfm) of air for each square foot of the door opening into the stairwell.
The control panel monitors and maintains the proper amount of pressure in the stairwell. It does this by constantly comparing the pressure in the stairwell to the pressure in the surrounding area. If the pressure in the stairwell drops, meaning more air is flowing out than in, the control panel will activate the blower unit to increase airflow and bring the pressure back up to the proper level.
Smoke detectors are a critical component of the stairwell pressurization system. They are responsible for detecting smoke and activating the blower unit when necessary.
The Benefits of Having a Stairwell Pressurization System
There are several advantages to having a properly functioning stairwell pressurization system for building fire protection.
- It helps to prevent smoke from spreading through the building in the event of a fire.
- It keeps the stairwells clear of smoke, making them easier to use as an evacuation route.
- It helps to prevent the spread of fire and smoke through doorways and other openings.
- It can help to reduce the amount of damage caused by a fire.
- It can help to save lives in the event of a fire.
