Interview on WCSH Following Tragic Drowning Accident
Escape and Rescue from Submerged Vehicles
Each year, there are approximately 1,200 - 1,500 incidents and 400 - 600 deaths involving vehicles that have gone off the road and plummeted into the water. Therefore, the public needs to plan for these types of emergencies by (A) rehearsing the steps necessary for a successful self-rescue from a vehicle in the water, and (B) having the rescue/escape tools readily available for use during this type of emergency situation. In addition, First Responder agencies need to provide the training necessary to prepare their personnel to respond to these types of incidents, and should provide the Personal Protective Equipment and rescue tools necessary for a safe and effective response to vehicles in the water.
Each year within the United States, there are approximately 1,200 - 1,500 submerged vehicle incidents resulting in 400 - 600 deaths. Therefore, the public needs to plan for these types of emergencies by (A) rehearsing the steps necessary for a successful self-rescue from a vehicle in the water, and (B) having the rescue/escape tools readily available for use during this type of emergency situation. In addition, First Responder agencies need to provide the training necessary to prepare their personnel to respond to these types of incidents, and these First Responders should be provided with the Personal Protective Equipment and rescue tools necessary for a safe and effective response to vehicles in the water. Furthermore, emergency dispatchers need to be educated to instruct callers to immediately get out of their vehicles if they are in danger of sinking.
Public service campaigns should be increased in an effort to educate the public about the risks of driving through flooded highways; driving in close proximity to bodies of water during snow, rain or other slippery conditions; or driving over lakes, rivers or ponds that have frozen over. The following information should be included in these efforts:
• It only takes approximately 6” to 2' of water to float a vehicle off its wheels. Drivers need to heed warnings about low water crossings and do not attempt to cross flooded highways.
• 8” to 12” of new, clear, hard ice is required to drive a small vehicle onto the ice. 12” to 15” of new, clear, hard ice is required to drive a medium-sized truck onto the ice.
• Wearing seat belts will increase your chances of surviving a crash into the water.
If a vehicle leaves the road and lands in deep water, most passenger vehicles will float on the surface for a short period of time (from 30 seconds to several minutes). But, all vehicles will sink! If the water is deeper than the height of the vehicle body, it will submerge and disappear beneath the surface. Factors which effect the float time include closed, sealed, and intact windows and weather seals, as well as the design, body style, construction quality, and the condition and age of the vehicle. Because of the location of the motor in the front of the vehicle, the vehicle will immediately assume an angled nose down position in the water.
A vehicle with the windows and/or doors open will submerge faster than the same vehicle with its windows and/or doors closed. The faster the water enters the interior of the vehicle, the faster it loses its buoyancy and the quicker it descends. A vehicle that has all the windows and doors closed will initially descend slowly, but as the vehicle loses buoyancy its speed of descent will increase.
Because of the relatively limited time frame for self-rescue, the decision to escape the vehicle must be made immediately. However, because of the angled nose-down position in the water and the pressure exerted by the water against the doors, as well as structural damage to the vehicle as a result the crash, it may be extremely difficult or impossible to open the driver's side and passenger doors of the vehicle in order to effect an escape. Therefore, the only avenue of escape may be through the car door windows.
Studies have shown that the electric power may stay on inside the vehicle for as much as an hour. However, once the window motors and/or switches get soaked, they will generally short out and the windows and electric door locks will no longer operate. Therefore, in order to escape through the car door windows, the occupants must be able to punch/break out the windows. Because the door windows, as well as the rear window, are constructed of tempered glass, they will easily shatter using an appropriate rescue/escape tool, such as a life hammer device, or a spring-loaded window punch (i.e. ResQMe). Many of the commercially available rescue/escape tools also have an integrated seat-belt cutter/blade that provides the ability to slice away a seat belt should its release mechanism fail or jam.
The decision to escape the vehicle must be made as soon as the vehicle leaves the road and enters the water. If the occupants delay their escape from the vehicle and the vehicle begins to sink, it may not be possible to effect an escape until the water pressure has equalized inside the vehicle. By that time, it is typically too late. Also, should the vehicle land in deep water, if the water depth is less than 14', the vehicle will usually come to rest on the bottom on all four wheels, assuming there are no large rocks or other debris on the bottom. However, water depths greater than 14' usually results in the vehicle turning turtle and landing on its roof. Needless to say, being upside down in a dark environment with water rushing in will totally disorient the occupants of the vehicle.
In order to advocate a single universal message to educate the public on how to escape from a submerging vehicle, we advocate the following:
GO (get out!)
In order to accomplish this, these emergency procedures should be rehearsed before the emergency occurs. Use a body reference point to identify and locate the door latch, window crank or electric window switch. As an example, the driver should practice finding the location of these by touching his knee or hip with his/her left hand and then move the hand laterally to the door. A rescue/escape tool should be immediately available for punching out the window and cutting seatbelts. This tool should be mounted on the sidewall of the driver's side compartment, attached to the key ring, or located in some other conspicuous location that can be easily accessed during an emergency. Consideration should be given to additional tools for the passenger side and rear seat compartments as well.
If there are multiple occupants, once an escape route has been opened, each occupant should hold hands in a human chain and escape from the same route. If young children are secured in car seats, the seat belts should be cut and the child removed. Some car seats are sufficiently buoyant to float a child to the surface. But, you should check with the manufacturer to determine whether or not your car seats are sufficiently buoyant to do so.
There is no doubt that when a vehicle leaves the roadway and plunges into the water, this would be an extremely frightening experience, especially during the winter months with cold water posing additional risks and hazards to the occupants. But, by rehearsing the emergency escape and survival procedures and having the rescue/escape tools readily available, occupants can safely and rapidly self-extricate themselves from this situation before the vehicle begins to sink.
Public Safety and Rescue personnel should be appropriately trained, protected, and equipped to effectively and safely respond to vehicles in the water. Besides the availability of Personal Flotation Devices (PFDs), Wetsuits, and/or Dry-Suits, rescue personnel should have the tools readily available to punch in the car door windows or the rear window in order to rapidly extricate a victim or multiple victims from a vehicle in the water. Spring-loaded window punches (i.e. ResQMe) or life hammer type devices with seat-belt cutters provide the rescuer with the opportunity to gain immediate access to the victims and to cut away the victim's seat belt for their immediate extrication from the vehicle.
As standard protocol, whenever a rescue agency is dispatched to respond to a vehicle in the water, the dispatch of a wrecker should be automatic in every community and emergency response system. Upon arrival of the wrecker, it can be used to assist in the stabilization of the vehicle during and after the rescue of the vehicle occupants.
We evaluated a number of rescue/escape tools. These tools are either hammer-type devices or spring-loaded window punch devices. Although both types of tools were effective in breaking door windows and rear car windows, we found that the hammer-type devices were more dependable, yet spring-loaded window punches that are mounted on the key ring are more readily available during an emergency.
Each of the spring-loaded window punch devices we tested were effective in breaking the windows when they were first removed from their packaging. However, after several practice drills, the points on these devices became dull which resulted in their failure to work and break the windows. Therefore, we caution against using the spring-loaded window punches for any purpose other than for breaking the windows. Furthermore, using a spring-loaded window punch, without appropriate hand protection during training, increased the chance of suffering cuts on the hand than the use of the hammer-type device. Regardless, rescue personnel should always wear an appropriate water rescue, neoprene, or fire glove when using any type of device to shatter door windows or vehicle rear windows.
All emergency dispatchers should be trained in this subject and should be prepared to give self-rescue and escape instructions to the callers prior to the arrival of Fire and Rescue personnel. The instructions provided by the dispatcher should include:
GO (get out!)
LAMINATED VS. TEMPERED GLASS
Presently, most U.S. manufactured vehicles are made with tempered glass in the doors, whereas, most European vehicles are manufactured with laminated glass. However, there is a movement to begin manufacturing all vehicles in the U.S. with laminated, rather than tempered glass.
Beginning with a phase-in period beginning September 2013, with full compliance by 2017, automobile manufacturers will be required to comply with a test in which an impactor is propelled at up to four locations from inside the perimeter of the side windows in the first three rows of a test vehicle at two time intervals following deployment of the side airbag. The ejection mitigation safety system is required to prevent the impactor from moving more than a specified distance beyond the plane of a window.
The Final Rule, published in the Federal Register in January 2011, does not mandate laminated glass, but it does establish performance requirements, which may lead to a particular technology, namely, laminated glass.
If the manufacturers begin installing laminated, rather than tempered glass, although the number of incidents will not increase, the number of fatalities will certainly increase as hammer-type devices and spring-loaded window punches are NOT effective on laminated glass. This will make escape almost impossible, and will hinder efforts of rescue personnel to access the trapped occupants.

PO-GO & SOS-GO
Prior to March 2013, Lifesaving Resources was advocating either PO-GO or SOS-GO, with the bottom line being to GET OUT of the vehicle as soon as possible. However, it was brought to our attention that these acronyms may not translate properly into other languages. So, for these reasons we've decided to phase out these protocols. However, we know these protocols work and they are basically the same as the new protocols described above.
Punch open the seatbelt
Open the window
Stay call and Assess the situation
Open the window or door
Disengage the Seatbelt

July 29, 2013
The following is an e-mail that was sent to the National Highway Traffic Safety Administration, several news outlets, and to two U.S. Senators from Maine on this date:
This matter deals with public safety and this issue needs to be addressed at the earliest opportunity.
I am a technical consultant for Lifesaving Resources, a company dedicated to drowning and aquatic injury prevention and emergency management. We have been striving to educate the public about the procedures to escape from a submerged vehicle and we have conducted this training throughout the U.S., as well as Internationally.
As a result of the two tragic deaths that occurred last week in Roque Bluffs State Park when two women drove into the ocean and drowned when they were unable to exit their vehicle, WCSH6 contacted me and did a story about How to Escape from a Submerging Vehicle. That story can be viewed on our home page at www.lifesaving.com.
We are trying to educate the public about escape procedures, as well as educating emergency dispatchers and first responders. The message needs to be rapid and simple encouraging those in distress to exit their vehicles as soon as possible. The steps are:
GO (Get Out!)
However, supposedly the federal government is mandating that side door windows, beginning in 2014, must be constructed of laminated, rather than tempered glass. Currently, there are approximately 1,200 - 1,500 submerged vehicle incidents annually resulting in 400 - 600 deaths. Once the vehicles have only laminated, rather than tempered glass, this will prohibit the ability of occupants to escape from their vehicles. The number of incidents will not be reduced, but the number of fatalities will surely increase.
I am writing to solicit your help in stopping this mandate until such time as the federal government can also require an alternative means of egress from the vehicle (i.e. escape hatch) with laminated glass.
