When responding to an emergency, a first responder is oftentimes exposed to a hazardous environment. The nature of the hazardous environment varies, for example, from exposure to toxic gases, to exposure of non-gaseous toxins, to exposure of dangerous site aspects (e.g., unstable structures, electric shocks and structures that present falling risks). The hazardous environments also result in physical and psychological responses that can be detrimental to the first responder. Stress, emotional fatigue, and physical fatigue are examples of responses that can result in a first responder’s harm both on the job in the environmental hazard and after the job is done.

A concept behind the present invention is that the collection and analysis of data from a hazardous, or potentially hazardous, environment can help to minimize exposure of a first responder to hazards. The minimization of exposure would further limit detrimental emotional and physical responses by the first responder.

In one aspect, the present invention provides a GPS main unit. The unit is portable, and typically cloud-based.

In another aspect, the present invention provides a data collection and tracking system for first responders. The system typically includes three components: 1) the GPS main unit discussed above; 2) a custom fitness wrist band for the collection of physiological data; 3) a dashboard where all data collected from the GPS main unit and fitness wrist band can be displayed in real time and stored in secure servers.

Fig. 1 shows one embodiment of a system according to the present invention. Resource 101 equipped with IMSAFE (personnel, vehicles, aircraft, heavy equipment operators, etc.) is shown. Two wearables of IMSAFE 102 are sown connected to resource 101, the Hub and the Band that gathers sensor data. The data collection system 101 and 102 transmits collected data and sends it to an LoRaWAN gateway 103. At gateway 103, edge computing takes place to refine and repackage the data. Gateway 103 then allows the data to be viewed in real-time at the location and simultaneously sends the data to cloud 104 via cellular or satellite connectivity 104. Once in the cloud 104, the data collected from resources 102 can be shared with other resources that are connected to the cloud 104 in real-time. The data is also simultaneously stored in secured servers for further use by the individual resource 101, fire department administrators, medical researchers or Red Line Safety, Inc. End users 105 use the real-time data collected from resources 101. This includes other crews, other command vehicles, anyone with a device connected to the cloud 104 and communication centers.

The custom fitness wrist band monitors a first responder’s physiological status. It provides a full spectrum of health and wellness data with applied algorithms for the first responder around the clock. Aspects of the wrist band include: an LCD display of critical data; HR display of heart rate in beats per minute; PPG display showing the oxygen saturation of blood; Skin Temperature, arrived at through machine learning to show whether a body is overheated or febrile; vibra alert to alert the first responder when alarms are activated.

The dashboard provides for the display of data gathered from the GPS main unit and the fitness wrist band. Data displayed by the dashboard includes, without limitation, the following: first responder location; first responder physiological status; atmospheric conditions; location and proximity to target hazards; hazardous environments; vehicle location and status; customizable map overlays; search options; large variety of filters; specific search bar; drawing tools; on screen timers/incident clock/PAR clock. In one aspect, a device for monitoring a first responder is provided, where the device includes: a case, to which is attached an antenna, a status light, a strobe light, an LCD screen and a thermal camera; a flexible printed circuit board assembly connected to an inside portion of the case, wherein the assembly includes GPS, a gyroscope, an accelerometer, and one, two, three, four or five toxic gas sensors.

In another aspect, a system for monitoring a first responder is provided. The system includes a GPS main unit, a custom fitness wrist band for collection of physiological data, and a dashboard where all data collected from the GPS main unit and fitness wrist band can be displayed in real time and stored in secure servers.

In another aspect, a method of obtaining, analyzing and displaying data related to a first responder is provided. Data is collected by the GPS main unit and the wrist band, both of which are worn by a first responder. The data is transmitted to the dashboard, where it is collected, analyzed and displayed.

In another aspect, a method of reducing fatigue in a first responder is provided. Data is collected by the GPS main unit and the wrist band - both of which are worn by a first responder - where the data includes infrared video of heat signatures, heart rate and oxygen saturation of blood. The data is transmitted to the dashboard, where it is collected, analyzed against standards derived for fatigue and displayed. If the display indicates that the first responder is experiencing i fatigue, he is contacted regarding next actions.

The biometric data collected by the GPS main unit and wrist band can be used to help ensure first responders are properly monitored during emergency operations. This data will allow for the ability to ensure adequate rehabilitation of the first responder before leaving the emergency scene. By improving their recover, first responders are more capable of going to another emergency with less fatigue and less likely to be injured.

One way to determine whether fatigue experienced by first responders has been reduced is to compare fatigue rates between groups of first responders who generally are exposed to a similar, or the same, risk of fatigue over a similar, or the same, period of time. See Yung et al. “Fatigue Risk Management for First Responders: Current Landscape of Perspectives, Policies, and Practices” https://www-assets.conestogac.on.ac. One group receives the benefit of a system according to the present invention; the other is not. The group receiving the benefit of the system typically will have a reduction in fatigue of at least 5 percent (e.g., reduction of five percent to ten percent). In other cases, the reduction in fatigue will be at least 10 percent (e.g., 10 percent to 20 percent). In still other cases, the reduction in fatigue will be at least 20 percent (e.g., 20 percent to 30 percent), at least 30 percent (e.g., 30 percent to 40 percent), or at least 40 percent (e.g., 40 percent to 50 percent).

In another aspect, a method of reducing injury experienced by a first responder is provided. Data is collected by the GPS main unit and the wrist band - both of which are worn by a first responder - where the data includes infrared video of heat signatures, toxic gas concentrations in the environment and oxygen saturation of blood. The data is transmitted to the dashboard, where it is collected, analyzed against standards derived for risk of injury and displayed. If the display indicates that the first responder is at risk for injury, he is contacted regarding next actions.

If it is determined that the first responder is at risk of medical emergency, or indeed injured, not only will their exact location be known; the location and qualifications of assistance resources will be known, since all operators will be displayed in real time on the dashboard. During an SOS, or emergency operation, the tabs and filter features of the dashboard may be used in a manner that will provide situational focus for the involved resources and incident priorities.

One way to determine whether injuries experienced by first responders has been reduced is to compare injury rates between groups of first responders who generally are exposed to a similar, or the same, risk of injury over a similar, or the same, period of time. See, Dannenberg c and Fowler, Injury Prevention 1998; 4:141-147. One group receives the benefit of a system according to the present invention; the other is not. The group receiving the benefit of the system typically will have a reduction in injury of at least 5 percent (e.g., reduction of five percent to ten percent). In other cases, the reduction in injury will be at least 10 percent (e.g., 10 percent to 20 percent). In still other cases, the reduction in injury will be at least 20 percent (e.g., 20 percent to 30 percent), at least 30 percent e.g., 30 percent to 40 percent), or at least 40 percent (e.g., 40 percent to 50 percent).

In another aspect, a method of reducing the rate of cancer diagnoses in first responders is provided. Data is collected by the GPS main unit and the wrist band - both of which are worn by a first responder - where the data includes toxic gas concentrations in the environment and radioactivity levels. The data is transmitted to the dashboard, wherein it is collected, analyzed against standards derived for cancer risk and displayed. If the display indicates that the first responder is at risk for cancer - e.g., significant smoke inhalation - he is contacted regarding next actions.

It is important to note that even though first responders (e.g., firefighters) wear industry approved personal protective equipment (PPE), the PPE is considered only a partial barrier to the many dangers of atmospheric and toxic exposure encountered by first responders. It is not 100 % protection. Having a digitalized record of exposure allows a better understanding of what might need to be performed to better prepare and protect the first responders - e.g., enhanced post exposure on-scene first responder detoxification, proper post exposure PPE cleaning, post exposure medical follow-up, etc.

One way to determine whether cancer diagnoses experienced by a first responder has been reduced is to compare cancer diagnoses between groups of first responders who generally are exposed to a similar, or the same, cancer risk over a similar, or the same, period of time. See, ( “Reducing Firefighter Cancer Risks”, https://www.powerdms.com/policy-learning-cenler/- reducing-firefighter-cancer-risks. One group receives the benefit of a system according to the present invention; the other is not. The group receiving the benefit of the system typically will have a reduction in cancer diagnoses of at least 5 percent (e.g., reduction of five percent to ten percent). In other cases, the reduction in cancer diagnoses will be at least 10 percent (e.g., 10 percent to 20 percent). In still other cases, the reduction in cancer diagnoses will be at least 20 percent (e.g., 20 percent to 30 percent), at least 30 percent (e.g., 30 percent to 40 percent), or at least 40 percent (e.g., 40 percent to 50 percent).

In another aspect, a method of reducing heart disease in first responders is provided. Data is collected by the GPS main unit and the wrist band - both of which are worn by a first responder - where the data includes toxic gas concentration in the environment, heart rate and oxygen saturation of blood. The data is transmitted to the dashboard, where it is collected, analyzed against standards derived for risk of heart disease and displayed. If the display indicates that the first responder is at risk for heart disease, he is contacted regarding next actions.

First responders (e.g., firefighters) often go from one emergency to the next. Having this data in real time allows on scene managers to know what steps must be taken to properly prepare the first responder to respond to the next emergency. This is where the value of proper rehabilitation applies. In addition, comparing this real time data to an individual’s historical data, which would be accessible while at the scene of an emergency, will allow for a better understanding of when each individual is properly conditioned to return to work safely.

One way to determine whether heart disease experienced by a first responder has been reduced is to compare heart disease between groups of first responders who generally are exposed to a similar, or the same, risk of heart disease over a similar, or the same, period of time. See Kales et al. “Emergency Duties and Deaths from Heart Disease Among Firefighters in the United States” New England Journal of Medicine 2007 Mar; 256(12) 1207-1215. One group receives the benefit of a system according to the present invention; the other is not. The group receiving the benefit of the system typically will have a reduction in heart disease of at least 5 percent (e.g., reduction of five percent to ten percent). In other cases, the reduction in heart disease will be at least 10 percent (e.g., 10 percent to 20 percent). In still other cases, the reduction in heart disease will be at least 20 percent (e.g., 20 percent to 30 percent), at least 30 percent (e.g., 30 percent to 40 percent), or at least 40 percent (e.g., 40 percent to 50 percent).

In another aspect, a method of reducing chronic respiratory diseases in first responders is provided. Data is collected by the GPS main unit and the wrist band - both of which are worn by a first responder — where the data includes toxic gas concentration in the environment and oxygen saturation of blood. The data is transmitted to the dashboard, where it is collected, analyzed against standards derived for risk of chronic respiratory disease and displayed. If the display indicates that the first responder is at risk for chronic respiratory disease, he is contacted regarding next actions. The main unit and the wrist band work together to provide real-time data for the environment a first responder (e.g., firefighter) is working in and how his body is performing and reacting in a given work environment. By knowing these important data points on the outside of a first responder’s PPE, and knowing the data points of how the first responder is physiologically responding on the inside of the PPE, one can differentiate whether a first responder is in crisis or simply working hard. This real-time data can be compared to historical data to help determine the level of stress a first responder is experiencing. Having such data stored will help guide the first responder to improved health and wellness over the course of his career.

On a larger scale, having this type of data, cleaned of all personal information, could help researchers better understand the effects of being a first responder and help develop focused studies to prevent, reduce and treat first responder (e.g., firefighter) illnesses.

One way to determine whether chronic respiratory disease experienced by a first responder has been reduced is to compare chronic respiratory disease incidence between groups \ of first responders who generally are exposed to a similar, or the same, risk of chronic respiratory disease over a similar, or the same, period of time. See Gupta et al. “Smoke Inhalation Injury: Etiopathogenesis, Diagnosis, and Management” Indian J Crit Care Med 2018 Mar; 22(3): 1 SO- 188.

One group receives the benefit of a system according to the present invention; the other is not. The group receiving the benefit of the system typically will have a reduction in chronic respiratory disease of at least 5 percent (e.g., reduction of five percent to ten percent). In other cases, the reduction in chronic respiratory disease will be at least 10 percent (e.g., 10 percent to 20 percent). In still other cases, the reduction in chronic respiratory disease will be at least 20 percent e.g., 20 percent to 30 percent), at least 30 percent (e.g., 30 percent to 40 percent), or at least 40 percent (e.g., 40 percent to 50 percent).

Examples

A test subject firefighter was fitted with a Maxim Wrist band and carried a cell phone in his pocket to record physiological data during his time in the bum area. The VMB was designed to bum away vegetation in a controlled manner. Units mostly in holding status but occasionally engaged in firefighting operations to control designed bum areas. Device removed from firefighter at the end of the day. Researchers immediately noticed a maximum heart rate of 208 bpm approximately 30-45 minutes prior to dropping off the equipment. An equipment diagnostic was performed. The technician said the band seemed to be in proper working order and had produced consistent data throughout the 3 -hour procedure. The firefighter was interviewed later in the day to determine what the circumstances were that may have contributed to the extremely high heart rate. The firefighter said that at approximately 11 :45, he encountered heavy smoke with high heat conditions and was having trouble breathing and coughing. He also stated that he had a lot of “snot running down my nose and all over my face at the time”. This timeline is consistent with the data collected per the researcher assigned to the subject firefighter. Later in the interview, the firefighter revealed that he had a tough time passing his pre-employment physical treadmill test because every time he was on the treadmill, he would have runs of asymptomatic SVT. After 3 failures, the subject firefighter had a doctor perform an ablation to his heart that seemed to resolve his cardiac abnormality. The firefighter was later able to pass his pre-employment physical and was hired. The subject was advised of the scientific findings, and with the information has the option to follow up with his doctor. The test subject received treatment from his personal physician and is SVT free. He will have regular, follow-up visits with his physician. This single case demonstrates the value of monitoring the physiological data of first responders (e.g., firefighters) during their work cycles. The data received and given to the test subject allowed him to seek medical attention, significantly lowering his risk of serious injury, or even death, under similar conditions in the future.
