One of the main problems facing fire detection systems in the UK is exposed/external environments is the unpredictable British weather. Almost every detection system (Smoke, Heat, and even some Flame Detectors) can suffer from reduced effectiveness in varying weather conditions. Common issues can include smoke stratification, temperature fluctuations, and false alarms through direct sunlight on a detector lens.

One exception to this rule is Thermal Fire Detection. This system remains effective almost regardless of the weather conditions. This feature is particularly useful for waste management sites with substantial operations or storage space in open buildings or uncovered areas.

How does it work?

All particles produce a certain amount of infrared radiation, but as the heat rises, the concentration of radiation increases. The camera identifies this increase in radiation, reading it as a rise in heat levels. Operators can configure the fire system to activate the alarm when radiation reaches a certain threshold.

Benefits

  1. Detection Method: Detects hot spots via infrared radiation instead of optical sight and is unaffected by low-visibility conditions. In addition, it doesn’t require 24-7 lighting like Video Smoke Detection, meaning there are fewer long-term running costs.
  2. Detection Speed: The system can detect a sudden rise in temperature and reach a set alarm threshold, alerting the operator to intervene before a minor issue turns into a major fire.To enable quick response, the video feed is transmitted to the central monitoring station, allowing operators to evaluate the situation promptly and take appropriate action.
  3. Installation Options: Unlike other stationary detection methods, the

Drawbacks

  1. Surface-risk Detection Method: Deep-seated fires can build up heat energy without being detected. Also, large stockpiles and bunker walls can obstruct the camera view, reducing its effectiveness if mounted at a diagonal angle.
  2. Type of Analytics: Un-intelligent software, thereby, site processes (e.g., vehicle exhausts, hot waste piles) may trigger false alarms. Heat maps streamed back to the central monitor can sometimes be hard for operators to read, creating confusion and resulting in incorrect action.
  3.  

Conclusion

Despite the drawbacks listed above, Blazequel regards thermal fire detection as the most effective fire protection system for external environments, as it is reliable, adequate in most weather conditions, and allows you to achieve a pre-emptive alarm before a fire can even break out. Careful system design can largely overcome the ‘blind spot’ issue with wide-lens cameras or a scanning camera system.

Video Smoke Detection for Waste Recycling

Video Smoke Detection is perfect for a fast response to fires in high roofed buildings and harsh operating conditions.

Real Fire - Smoke Detection in MSW Storage

Watch Smokecatcher detect smoke in an MSW storage building. The smoke is coming through from a fire in the adjoining storage area.

Real Fire - SRF Storage Area

Watch Smokecatcher detect a fire in an SRF Storage bunker. Sadly, the alarm wasn’t responded to and the site lost a 4hr window of opportunity between smoke detection and flames appearing.

Video Smoke Detection for Logistics

Video Smoke Detection overcomes the risks of stratification and other challenges for early fire detection in logistics and storage facilities.

EFW Bunker Fire

Watch Fire Rover detect and suppress a fire in the waste bunker at an EFW facility!

Tipping Hall Fire

See how the Fire Rover detects and suppresses this fire at a clients tipping hall. Note how the smok is spreading out at low leve, rather than rising. This is called ‘stratification’ and is one of the many reasons why roof-mounted smoke detection systems like beam detectors and HSSD is not suitable for many recycling applications.

Battery Storage Fire

Watch the Fire Rover detect and suppress a fire at a battery storage facility. This targeted and intellegent control makes the Fire Rover particularly well suited to high hazard storage applications.

Explosive Lithium-ion Batter Fire

Watch the Fire Rover tackle a battery fire in a tipping hall. Note how the exploding battery cells start three separate fires, which the operator individually suppresses (whilst avoiding the site operators in the vicinity).
