Passive Smoke Control System

These systems fall into two categories.

Passive smoke control system.

Smoke control systems or smoke management systems are mechanical systems that control the movement of smoke during a fire. Fire protection engineers should consider the building s construction fire suppression systems and smoke control when designing active and passive fire protection systems. Only the off condition shall de energize the smoke control equipment while providing a fault status as required by labc section 909. A system that shuts down fans and closes dampers to limit the spread of fire and smoke.

Find out information about smoke control system passive. Given the limited application of passive smoke control systems the focus is generally on active mechanical systems. Pfp attempts to contain fires or slow the spread such as by fire resistant walls floors and doors. Looking for smoke control system passive.

The designs are based on select design objectives presented in. Pressurization exhaust and airflow. Pfp systems must comply with the associated listing and approval use and compliance in order to provide the effectiveness expected by building codes. Passive systems use smoke barriers or partitions to limit and control the movement of smoke in certain directions or allow it to accumulate in a properly sized reservoir e g.

The international building code and nfpa standards provide guidance on passive and active fire protection systems. Smoke control systems can be either mechanical or passive just like ventilation systems. The most common systems referenced in current codes are atrium smoke exhaust systems and stair pressurization systems. Each of these types of systems has its place and each can be a very effective means of safeguarding the building occupants from exposure to the products of.

This standard shall apply to the design installation acceptance testing operation and ongoing periodic testing of smoke control systems. Types of systems there are two basic types of smoke control systems. Under reverse stack effect conditions where the exterior is hotter than the interior the smoke control system performance is the opposite of the case of normal stack effect. Passive fire protection pfp is an integral component of the components of structural fire protection and fire safety in a building.

The top of an atrium active smoke control can be divided into three subcategories. A mechanical smoke control system uses fans to establish an airflow that prevents migration of smoke into means of egress or other key building areas while passive smoke control features use physical barriers to prevent smoke migration between different. Most are intended to protect occupants while they are evacuating or being sheltered in place.
