A ground-breaking trial using 4G LTE cellular connectivity to enable beyond-visual-line-of-sight (BVLOS) drones to deliver automated external defibrillators (AEDs) to the scene of a cardiac arrest has taken place in the County of Renfrew, Ontario, Canada.

Working in partnership with technology providers, including InDro Robotics, Cradlepoint and Ericsson, the trial demonstrated the drones’ capabilities to arrive more than seven minutes before paramedic vehicles during each test flight.

Plan Deployment Strategies

The County of Renfrew Paramedic Service will use these results to plan deployment strategies that reduce time to treatment for people suffering cardiac arrest, and for those who need urgent medications, in private, residential or rural locations.

The trial involved the County of Renfrew Paramedic Service flying the first LTE-connected drones equipped with AEDs

Completed in September 2019, the trial involved the County of Renfrew Paramedic Service flying the first LTE-connected drones equipped with AEDs to locations in a 10-mile operating radius that are BVLOS of emergency services and pilots.

This project is one of the first in the country to be granted permission for this capability, which could significantly expand the reach of these emergency services. Successfully delivering AEDs to remote patients in need has the potential to improve survival rates for people suffering cardiac arrest or other dire medical conditions.

Crucial In Saving The Victim’s Life

The trials on September 21-22, 2019 were a resounding success, with the drone arriving at least seven minutes before the paramedic vehicles during each test run. The drone flew over cellular to remote take-off points selected by GPS and landed successfully to deliver an AED to the onsite researchers.

They then utilized the device to deliver required shocks to a medical mannequin. Translated to an actual cardiac arrest, the extra time provided by the drones would be crucial in saving the victim’s life.

LTE Connectivity For Control Data And Video

As technology partners for the trial, InDro Robotics supplied the unmanned aerial vehicles (UAV), with Cradlepoint providing its NetCloud Service, including the on-board, rugged IoT router that enables LTE connectivity for control data and video between the vehicle and its pilot over a Canadian mobile carrier’s LTE advanced cellular network.

Emergency services have operated within the limitations of non-cellular communications technology

Ericsson will offer 4G LTE equipment with carrier aggregation, as well as its cellular network design support and drone research. The advanced drone and BVLOS traffic management technologies provided by InDro Robotics and Ericsson, and use of LTE for control and real-time video streaming provided by Cradlepoint and the mobile carrier, form the centrepiece of the County of Renfrew trial and its objective to increase the range and reduce time-to-site for remote cardiac arrest victims.

Drones To Assist Emergency Services

Previous line-of-sight trials using drones to assist emergency services have operated within the limitations of non-cellular communications technology and without the ability to use video, limiting them to trips of approximately 4.5 miles.

By using the LTE cellular network, the County of Renfrew initiative offers the potential to deliver AEDs to patients up to 80 miles. To improve the mission-critical communications associated with these deliveries, the drones share images and video with operators and employ artificial intelligence to manage key functions, such as collision avoidance, all enabled by the speed, bandwidth and reliability of the LTE cellular network.

Impact On Emergency Care For Patients

Given the large area and varied terrain that the county encompasses, it is often difficult to get paramedics to patients in a timely fashion, so we have taken a layered approach to their response. We have been successfully using drones to support our emergency responders for several years, but until now, the operators have had line-of-sight of the situation. We will now have further reach than ever,” explained County of Renfrew Paramedic Chief Michael Nolan.

I am very impressed with the results of these flights, advancing the science and operations"

What’s particularly innovative and exciting about this trial is the potential of drone-delivered AEDs to have a transformative impact on emergency care for patients suffering cardiac arrest, especially those in remote private, residential or rural settings, where getting emergency treatment rapidly is the difference between life and death.”

Custom Design Solutions For Complex Missions

I am very impressed with the results of these flights, advancing the science and operations, delivering life-saving tools such as a defibrillator by drone,” said Dr. Sheldon Cheskes of Sunnybrook Health Sciences Centre.

This new drone technology is especially exciting when integrated into critical scenarios for paramedics – effectively enabling AED ‘on the fly,’” noted Philip Reece, CEO, InDro Robotics. “At InDro Robotics, part of what we focus on is custom design solutions for complex missions, and this is a perfect example of how drone software and hardware can provide a scalable solution to a very real problem. We’re thrilled to be part of this partnership, and to be able to demonstrate the capacity for drones and cellular technology at this life-saving trial.

Public Safety For Rural Communities

This trial is an amazing illustration of one of Ericsson’s core beliefs, Technology for Good,” said David Everingham, vice president and chief technology officer, Ericsson Canada. “Ericsson’s portfolio for Critical Broadband Network capabilities allows service providers and government operators to meet the tough business and mission critical communication requirements on a cellular network. We are proud to partner on this innovative trial, as multiple companies join together to test how we can use 4G LTE networks and drones to help save lives in Canada.

The County of Renfrew’s forward-thinking approach to using UAVs and on-board cellular connectivity to extend the speed and range of delivery for life-saving emergency services represents how connected technology is transforming public safety,” commented John Campbell, vice president, Public Sector and Canada, Cradlepoint. “We are honored to be a part of the County of Renfrew’s ground-breaking trial, which promises to help advance public safety for rural communities everywhere.”

How Can We Better Ensure Firefighter Health And Wellness?
How Can We Better Ensure Firefighter Health And Wellness?

Ensuring the health and wellness of firefighters is a burden shared among equipment manufacturers as well as the fire departments and individual firefighters. Thoughtful design of equipment and other products used in the fire service can be a positive factor as firefighters and other first responders face dangerous situations every day. We asked our Expert Panel Roundtable: What steps can we take to better ensure firefighter health and wellness?

Maintaining Fire Safety Through A Pandemic
Maintaining Fire Safety Through A Pandemic

There have been challenges with completing fire safety maintenance and installation projects during the current Covid-19 crisis, most notably as a result of the difficulties for installers in safely accessing sites. Many construction projects halted for lockdown and this resulted in approximately 50% of the British installers we work with having to furlough staff. The challenges, however, are not just restricted to the UK. With Kentec panels sold in more than 90 countries across the world, we have seen varying challenges on a global scale. Throughout this crisis, fire safety continues to be paramount and as such key players, such as Kentec, are rightly considered essential businesses. We have continued manufacturing life safety systems throughout the current difficulties and it has been our mission to ensure that where new installations can take place, our panels are readily available to installers, as well as the expertise and technical support that goes with it for ongoing maintenance. Orders for spare parts have also, in fact, been consistently high during this period, as installers have been able to complete minor upgrades safely and end users have taken advantage of the period to do so. Adapting manufacturing processes to align with government guidelines so that customers have not experienced any supply issues with any life safety systems or parts has been a major success. Critical Infrastructure We’ve personally seen an increase in sales for our industry-leading Sigma XT extinguishant panels during this crisis as it is widely used within critical infrastructure, in sectors such as telecommunications, data centres and healthcare. Adapting manufacturing processes to align with government guidelines has been a major success During lockdown, with a vast proportion of the population working from home and relying on the internet to conduct their business and virtual meetings, it has been more important than ever that there is no loss in service in broadband and telephone services. This means that highly reliable and robust fire extinguishing systems are essential to protect essential workers and vital equipment – not only from the risk of fire, but also from the catastrophic damage that false alarms and the release of extinguishant could have, for example, on server room equipment. Understandably, this has resulted in considerable investment in fire systems in these sectors. Glasgow’s Louisa Jordan NHS Facility The recent fire safety installation at the Louisa Jordan NHS Facility Glasgow – located at the Scottish Event Campus (SEC) which provides more than 500 COVID-19 beds – is just one example of essential fire safety work being completed during lockdown. Vipond Fire Protection Ltd installed a total of seven Sigma XT gas suppression panels, and 32 detectors located within the electrical room that serves the 10,000m2 facility. The project was completed in what was an extremely tight seven-day turnaround, delivering proven reliability within a crucial healthcare facility. Kentec's Experience Operating Through Covid-19 We have learned that operating through this crisis and supporting installations that are going ahead is best achieved through detailed planning, communication and collaboration. For example, we’re supporting our distributors by shipping directly to their customers, when it is not safe or feasible to open their warehouses. Operating through this crisis is best achieved through detailed planning, communication and collaboration Our own workforce is also adapting to changing work patterns and demands. In the factory, at a practical level, this has meant implementing new shifts schedules starting from six o’clock in the morning to ten o’clock at night to ensure there are never too many people on site at one time. We have staggered arrival, leaving and break times to mitigate any risks involved at entrances, and we were lucky that space allowed us to make the canteen area bigger and increase the number of toilets from three to ten. We have moved work benches to ensure a safe distance between each employee, and where workflows make two-metre distancing impossible we have installed six- and eight-foot screens. Face masks have been provided to all staff and we are also trialling face shields for further comfort and protection. Our office staff have worked from home, and where going to the office has been necessary, they have similarly adhered to staggered arrival times. Internal communication has been essential and I’m immensely proud and extremely thankful for the positivity, proactivity and support that employees have shown through this process.     We have also adapted our Kentec Installation Partner (KIP) scheme to be fully remote to ensure training and support is there when it is needed for our installers. We are hosting webinars as another forum to solve installer queries remotely, and our new range of Taktis panels have highly advanced networking capabilities and a vast suite of communication tools that support remote monitoring. It is therefore critical that our installers fully understand how to help end users realise the benefits such panels can deliver and to ensure their installations are completed successfully. Looking Ahead To The New Normal Remote monitoring will become increasingly important beyond this crisis We feel that remote monitoring will become increasingly important beyond this crisis and the advanced communication capabilities of panels will be essential for both installers and end users alike. For installers it reduces the amount of time required on site, because they can access the system remotely to find out what equipment or parts they need to take with them. Similarly, for end users they can access systems remotely to check any alerts or queries off site if necessary. It remains to be seen how the rest of 2020 will pan out, but where projects have been necessarily put on hold, because of the essential nature of our industry we are confident that installers will be able to quickly and easily return to these projects when it is safe and feasible to do so. Communication, collaboration and support will continue to be essential in mitigating the challenges in our future ‘new normal.’

Even with Firefighters Retiring Earlier, Pension Costs Remain Manageable
Even with Firefighters Retiring Earlier, Pension Costs Remain Manageable

Because the physical challenges take a toll, firefighters tend to retire at earlier ages than other occupations. There is also a greater likelihood of workplace disability. Firefighter pension plans are often more generous to offset a lack of Social Security eligibility for some public safety employees. Also, more years of retirement translate into an overall increase in medical care costs for fire service retirees. Therefore, pension benefits for public safety workers are more expensive than those for other government employees, according to an analysis by the Center for State and Local Government Excellence (SLGE). Even so, retirement costs for firefighters and police officers represent only a small percentage of total expenditures for city, county and school district jurisdictions – around 2%. Even if you focus on jurisdictions in which public safety costs are most significant—the city and county levels – the burden is still small, averaging only 4.9% of aggregate spending for cities and 1.9% for counties. Pension Changes Could Impact Firefighter Recruitment Pension benefit generosity is about 25% greater for police and fire employees Any changes in retirement or medical care plans could negatively impact efforts to recruit enough firefighters, which are already a challenge. For example, shifting the retirement age would reduce total employee compensation, which could negatively affect retention. A wage increase to offset the change would maintain total compensation at previous levels. In 2016, the costs of pension benefits earned for police and fire personnel made up 15% of the payroll, compared with only 8% for non-public safety local employees. Annual retiree health care benefits made up 6% of payroll, compared to 4% for other employees. Analyzing Retirement Benefits Earlier retirement ages translate into longer retirement periods for these workers, which impact higher pension costs. Public safety employees are eligible for their benefits at younger ages than other groups, even though the average expected lifespans at retirement are similar. Pension benefit generosity is about 25% greater for police and fire employees, a difference that offsets the lack of Social Security coverage for some public safety employees. Any changes in retirement or medical care plans could negatively impact efforts to recruit enough firefighters, which are already a challenge “Local governments across the country are continually analyzing the retirement benefits provided to the public safety workforce, along with associated costs,” says Joshua Franzel, PhD., President and CEO of SLGE. “This research provides government leaders and policymakers with a national snapshot so they can make informed decisions.” Outdated Assumptions? Some evidence suggests that assumptions about earlier retirement ages for police and firefighters may be outdated. Despite the physical demands of the jobs, some local governments have sought to retain experienced employees using a Deferred Retirement Option Plan (DROP), which allows employees to claim pensions while continuing to work. Higher DROP participation rates – with some public safety employees working five years longer – suggest that employees may be able to stay on the job until later ages. Also, the U.S. Army (whose jobs can also be physically demanding) has raised its mandatory retirement age for active duty soldiers from 55 to 62.  emphasizing employee health and fitness Use of technology can help to ease the physical burdens of public safety jobs, and an emphasis on employee health and fitness can also improve the picture. The analysis was conducted by CPR researchers Jean-Pierre Aubry, Associate Director of State and Local Research; and Kevin Wandrei, Research Associate. The research assesses the size of public safety retiree benefit costs using public safety employee data from the Public Plans Database, the U.S. Census Bureau, and government actuarial valuations.
