Study Notes
HVAC Systems in High-Rise Buildings
- High-rise buildings rely on Heating, Ventilation, and Air Conditioning (HVAC) systems to circulate heated or cooled air and maintain a suitable mixture of fresh and recycled air throughout the building.
HVAC System Conflict with Fire Service Ventilation
- A conflict may arise between HVAC and Fire Service Ventilation in high-rise fires due to the size and complexity of the HVAC system and structure.
HVAC and Fire
- Continued operation of the HVAC system during a working high-rise fire or large building complex may aid or hinder fire attack and tactics.
- Smoke and heat detectors are required at different locations within the system to shut down specific zones or components if products of combustion or heat are detected in the distribution system.
- Fan shutdown stops mechanical fresh air to the fire area.
- Fire dampers are similar to automatic fire doors, operating by fusible link connections to stop fire spread.
- Failure of components from direct exposure to fire, faulty installation, or simple malfunctions can quickly complicate a fire scene.
Pressurized Floors and Stairwells
- The Ontario Building Code requires many safeguards in HVAC systems to prevent or minimize smoke extension from the area of origin.
- When the fire alarm is activated, the ventilation system should shut down the ventilation system on the alarm floor and pressurize stairwells and firefighter elevator shafts until the fire alarm panel is reset.
HVAC Considerations for Fire Services
- The Incident Commander must address the status of the HVAC system as part of initial size-up and IAP development.
- Anticipation of smoke travel is based on experience, building familiarization, and the characteristics of the incident at hand.
- HVAC systems require qualified individuals to assess, troubleshoot, and operate due to their complexity.
