Staircase Pressurization System Testing

We are in the process of tc of a pressurization system in our project. The stair case pressurization fan is vfd driven and the fan ramp up down is based on the feedback of the pressure sensors installed in the stair well one sensor in 11 th floor and another in 17 th floor. The pressurized air helps people escape the fire and firefighters battle the fire.

The purpose of this procedure is to define the step by step method to implement the correct practices for the precommissioning commissioning of staircase pressurisation system through the guidelines contained herein so as to ensure that the job execution complies with the project requirements and serves the intended function to satisfactory level.

A critical component of any facilitys fire control and life safety system stairwell pressurization keeps exit routes smoke free in the event of a fire.

Staircase pressurization system testing. This course discusses the smoke control systems and examines the design considerations associated with stairwell pressurization systems. Pressurization system is the most widely selected design option. Staircase pressurization system smoke extraction 2. Stairways are fire escape routes nowadays stairwells have better fire ratings than the rest of the building.

Where pg ii building is provided with a mechanical ventilation system or pressurisation system for its staircase storey shelter an automatic smoke detection system complying with ss cp 10 shall be installed. The building is with 22 floor and the fire escape stair cases and lift lobby smoke stop lobby are pressurized. The smoke detector shall be located at the entrance of each exit staircase at every storey including the non residential floors. A key benefit of the system was that opening doors to the stair did not significantly impact on performance and the system could be applied on multiple floors simultaneously giving fire fighters much greater flexibility of operations.

Animation on the novenco clear choice pressurization system for staircases and escape routes. Similarly the system was found to need approximately 13 of the air supply plant that a pressurization system would require. Ventilationair conditioning control system vac an automatic control system designed to stop mechanically induced air movement within a designated fire compartment actuated by smoke detectors and provided with a central manually operated backup facility.

In case of fire in a high rise building a stair pressurization fan spf uses clean outside air to pressurize the air in stairwells. Trouble arises when a stairwell loses pressure as its doors open and close. The system is 100 compliant with the pressure differential system as described in the european.
