Understanding Fire Damper Breaches with System Hygienics

Fire dampers are critical components in a building's fire safety strategy. They prevent the spread of fire and smoke through the HVAC (heating, ventilation, and air conditioning) system. However, understanding what constitutes a fire damper breach and how to fix it is integral for maintaining safety standards and compliance.

‍

What is a Fire Damper Breach?

A fire damper breach occurs when a fire damper fails to close correctly, allowing smoke and fire to penetrate through the ductwork into other building areas. These breaches can happen in mechanical and motorised fire dampers, each exhibiting signs of failure.

- Mechanical Fire Dampers: These dampers operate through a gravity-based system. If there is a breach, you may observe that the blades remain open or fail to return to their closed position during a fire event. This can often be caused by a build-up of dirt, debris, or misalignment, which prevents the damper's blades from functioning correctly.

- Motorised Fire Dampers: These rely on an electric motor to drive the blades' opening and closing. The engine may fail in a breach due to power outages, mechanical failure, or control system errors. Symptoms often include an audible alarm or warning signal, and visual inspection may show the blades stuck in an open position.

How Are Fire Dampers Triggered?

Heat detectors or smoke detectors typically trigger fire dampers in the vicinity. When a sensor senses a dangerous rise in temperature or smoke presence, it sends a signal to the damper’s control system, causing it to close. However, if there is any mechanical or electrical failure, this crucial response may not occur, leading to a breach.

‍

Why Do Fire Dampers Fail?

Several factors can contribute to fire damper failures:

1. Poor Maintenance: Regular maintenance is essential for a fire damper's efficient operation. Neglect can lead to dust and debris accumulation, which hinders functionality. Not only does this hinder functions, but it will also impede whether you comply with legal regulations and guidelines.

2. Corrosion: Environmental factors like humidity can lead to rust or corrosion affecting the damper components, particularly in older systems.

3. Mechanical Damage: Physical damage from construction or malfunctions can misalign the damper blades, leading to a breach.

4. Electrical Failures: Electrical issues such as faulty wiring or power interruptions can cause failure to respond correctly during a fire event for motorised dampers.

5. Improper Installation: Incorrectly installed dampers may not perform as intended, leading to breaches over time.

Fixing Failed or Breached Fire Dampers

Addressing a fire damper breach requires a systematic approach:

1. Inspection: The first step is to carry out a thorough inspection of the fire dampers. This includes visual checks and functionality tests to determine if the damper closes and seals appropriately.

2. Cleaning: If dust or debris is found, the damper should be cleaned to ensure no foreign materials prevent its movement.

3. Repair or Replace: If any part of the damper is damaged—whether mechanical, electrical, or structural—it may need repairs. This may fall under remedial works and maintenance. Components like motor actuators, hinges, or blades might be the focus of repair efforts.

4. Recalibration: After repairs, it's essential to recalibrate motorised dampers and ensure that control systems function correctly.

5. Documentation: Maintain records of inspections, repairs, and replacements. Regular documentation helps in tracking the maintenance history and planning future checks.
