Active fire safety, often referred to as active fire protection, involves systems and measures that require action to be taken to detect and alert, stop or contain a fire.
This type of fire safety is crucial because it focuses on the actions necessary during a fire event to minimize damage and protect occupants. Unlike passive fire safety, which involves building materials and design elements that resist fire, active systems actively intervene when a fire occurs.
How Does Active Fire Safety Work?
Active fire safety systems are designed to respond automatically or manually to the presence of fire or smoke. Their primary goals are:
- Detection: Identifying a fire incident as early as possible.
- Alerting: Notifying occupants and emergency services.
- Suppression/Containment: Taking steps to extinguish the fire or prevent its spread.
As highlighted in the reference, this may involve:
- Manual Actions: A person taking direct action.
- Automatic Actions: Systems that operate without human intervention once triggered.
Examples of Active Fire Safety Systems
Here are some common examples of active fire safety measures:
-
Manual Systems:
- Using a portable fire extinguisher to put out a small fire.
- Operating a fire hose reel.
- Manually activating a fire alarm pull station.
-
Automatic Systems:
- Smoke Detectors: Devices that sense smoke and trigger alarms.
- Heat Detectors: Devices that sense abnormal increases in temperature.
- Automatic Sprinkler Systems: Systems that release water directly onto a fire when activated by heat.
- Fire Alarm Systems: Networks of detectors, alarms (sirens, lights), and control panels that alert occupants and can notify emergency services.
- Gaseous Suppression Systems: Systems that release inert gases or chemical agents to suppress fires in specific areas (e.g., server rooms).
These systems work together to provide a comprehensive response to fire incidents, requiring action to be taken to either detect and alert, stop, or contain the fire, thus protecting lives and property.
