Most modern buildings have various fire safety installations such as escape routes, safe spaces, ventilation systems, sprinkler systems, alarms, and more. The stair pressurisation system is another vital component of a building’s fire safety infrastructure.
This installation increases the air pressure in a stairwell and makes sure the smoke from rooms does not enter the enclosed area when the doors are closed. One of the most critical components of this system is a stair pressurisation relief. At Climacool, we make sure you have effective relief systems in place to aid in egress.
What is Stair Pressurisation Relief?
When the stairwell is pressurised, it has higher air pressure than the surrounding areas. This means it can become difficult to push open doors to assess the safe zones. Most people don’t have the strength or patience to push such doors open. A relief system eases the pressure without letting the smoke enter these areas in your stairwell. People don’t need to use much force to get through doors and access safe egress routes.
A stair pressurisation relief system comes in two distinct forms. You can use natural or passive methods, but they aren’t very reliable and can create uneven pressure. The last thing you want is for the smoke to flood safe egress zones and make things difficult.
The other option is mechanical solutions. We can provide relief through an automated window opening device, sub-ducts that are connected to smoke exhaust systems or ventilation systems, or combination dampers. All three solutions are practical and will reduce the pressure enough to make the door opening easy. Our experts will recommend the best option based on your specific requirements.
