Trusted, Accurate, and Connected Weather Monitoring for Firefighters
Fighting Fires With Knowledge
Every successful fire management strategy starts with accurate on-site weather observations. Kestrel Fire Weather Meters measure all relevant weather variables needed by Fire Behavior Analysts (FBAN’s), meteorologists, and deployed firefighters to understand how a fire is evolving and how to keep the crew safe. The new PRO line of Kestrel Fire Weather Meters give you the ability to track conditions and view trends right on the unit, as well as send detailed data reports using the free Kestrel LiNK app. The PRO meters also have the National Wildfire Coordinating Group (NWCG) Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) tables built right in, eliminating the complexity, time and errors involved in employing paper lookup tables. Unlike a traditional belt weather kit, a Kestrel Meter is ready to take all readings instantly, and the PRO meters log temperature, humidity and pressure even when off, giving instant visibility of trends.
Kestrel Fire Weather Meters are ready to take measurements instantly, with no setup or lookup tables required. PRO meters have the FDFM and PIG tables built right in, and log temperature, humidity and pressure even while off.
Sling Vs Kestrel: Lab Study Finds Kestrel More Accurate
Study Summary: Lab Testing Finds Kestrel Meter RH Measurement To Be More Accurate Than Traditional Sling Psychrometer
These data show it's really hard to get reliable repeatability with the sling. That means you can’t trust the sling for trend data. Our data show that even trained firefighters demonstrate tremendous variability both in technique and ultimately the end result. Even when we standardized the sling protocol, we still saw inaccuracies and inconsistencies as compared to the Kestrel [meters] and a calibrated RAWS.
When managing a burn site, knowing environmental conditions are within prescription is important for compliance and to ensure that a fire doesn't get out of control. A Kestrel Fire Weather Meter provides wind speed, wind gust, average wind, temperature and humidity readings for monitoring conditions while burning. But, gathering sufficient weather data to make a decision on when to burn can require many time-consuming site visits prior to the burn. The new Kestrel DROP D3FW Fire Data loggers can be left on site to record days of round-the-clock temperature and humidity readings which can then be viewed on a mobile device and shared via email with the free Kestrel LiNK app – providing instant insight into the time of day with most conducive conditions. Although you do need to return to site to collect the data, you don’t even need to retrieve your DROP each time – the full data log is transmitted wirelessly as soon as you are within connection range (100' line of sight or more).
A Kestrel DROP D3FW is a great extension of the Kestrel line. Just leave it in place to log temperature and humidity round-the-clock and gain insight into the best time to conduct prescribed burns. Like all Kestrel Fire Meters, a Kestrel DROP is fully sealed and very tough.
The Kestrel meter is much quicker to use for gathering immediate weather info then to use the old style sling method during firefighting activity in the Wildland setting. I've had my Kestrel meter for 5 years now and it’s still in good shape despite all the heat and water it's been exposed to on the job.
Urban Fire Fighting
Safety demands accurate situational wind speed measurements BEFORE deploying ladders and aerial equipment, and a Kestrel in the glove box is just the answer. Where a wildland fire has the potential to threaten an urban interface, a Kestrel Meter can assist in assessing the fire weather and predicting fire behavior.
The readings are consistent with my check devices. I like the fuel moisture tables. They are easy to use and the tool is durable and weather proof. It fits in just about any size pocket or can be tied to a vest or shoulder harness for convenient access.
Heat Stress Safety: Training & Operations
Wildland firefighters train to withstand the challenge of heavy exertion in extreme conditions. Extreme heat is a constant companion, and protective gear exacerbates the physical strain on a firefighter's body. Building heat acclimatization is a critical component of training, but doing so without incurring heat illness or injury is equally critical and challenging. Heat injury is a constant danger with many incidents of heat related illness occurring every year. Heat illness prevention programs recommend measuring Wet Bulb Globe Temperature (WBGT) and implementing ACGIH work/recovery and hydration guidelines. WBGT is a much more complete measure of heat stress for the firefighter because it includes the radiant heat of the sun, fire, or hot surfaces in the model. The Kestrel Fire Weather Meter PRO with WBGT adds the WBGT measurement to the full capability of the Fire Weather Meter Pro – making it the complete tool for monitoring WBGT and fire weather during training or operations. With pre-programmed ACGIH guidelines and alert settings to indicate when conditions have become extremely unsafe, the Kestrel Fire Weather Meter PRO with WBGT is the ultimate tool for increasing the safety of your crew.
By adding waterless WBGT readings to the full capabilities of the Kestrel Fire Weather Meter PRO, Kestrel has created the ultimate tool for protecting lives, houses, and property while ensuring safety for everyone involved.
Sharing better and quicker weather data and interpretation can increase our time to respond — an argument for the value of the Kestrel 5500FW in our arsenal of weather tracking tools that supports a safer fireground.
HAZMAT & NBC Response
First responders can gather the weather data they need within seconds of arriving at the scene with no tedious setup. A Kestrel 5500FW with LiNK wireless communication and Portable Vane Mount make up a complete Hazmat weather kit capable of measuring all parameters required for CAMEOALOHA and PEAC plume modeling. Equip every department vehicle with a Kestrel response kit to enable all personnel to measure and record life-saving data whenever and wherever they deploy.
Firefighters have come to depend on Kestrel meters for critical information on current weather conditions. Correct and current knowledge of weather conditions plays a key role in keeping firefighters safe, and properly fighting and extinguishing fires.
