PED fires can occur on planes + on the ground

Laptops may be safely contained

Other devices like cell phones are also at risk

More about PlaneGard™

PlaneGard™ is a fire containment case that is designed to protect people and property from Lithium-ion battery fires that can occur in Portable Electronic Devices (PED’s) such as laptop computers, tablets, readers, smart and cellular phones, digital cameras, and MP3 players.    A fire on an airplane, office building or cruise ship is a dangerous situation since there is virtually nowhere to run or hide and separate people from the event.  The flames and toxic organic vapors can become overwhelming in a matter of seconds – especially in the confined spaces of an aircraft. PlaneGard is the only 100% containment technology available.  PlaneGard fully contains and renders harmless the flames, heat, smoke, toxic fumes and  flammable vapors that are associated with a PED in thermal runaway.  See our videos on the "How It Works" page for a dramatic comparison between PlaneGard and the burn bag competition.  As you will see, burn bags do not contain the smoke, fumes and vapors!

We all know that Lithium-ion (Li-ion) batteries are extremely powerful and do a great job of powering our portable world.  What many of us do not know is that they can be extremely dangerous.  Each year a growing number of commercial airliners and private aircraft have to be diverted and make emergency landings because of burning Li-ion batteries due to the increasing number of PED’s being carried onboard by passengers and most airlines are installing charging stations in many seats on aircraft.  Each year laptops and cellphones are also responsible for dozens of house fires, related damage and even death.  The fact is that Li-ion batteries can spontaneously generate heat through a process called “thermal runaway”, and can even cause a fire/explosion when the laptop or cellphone is powered off!   With PlaneGard on board, this type of emergency can be safely and quickly handled.  PlaneGard can be used on an airplane to capture, contain and control the heat, flames, toxic organic vapors, smoke, odor and passenger panic associated with these fires.  There is no longer a need to make an emergency landing saving the operator considerable expense.  Please see the associated description and video below for more details.

In Memory Don Coffman

Mr. Gilchrist is a degreed Mechanical Engineer. Mr. Gilchrist has worked in the industrial chemicals industry before becoming part of the battery industry and has held positions in engineering and maintenance, product development, marketing and sales, and executive management.

Dr. Brilmyer holds a Ph.D. in electrochemistry from the University of Texas at Austin where he studied under Professor Allen J. Bard.  He has held numerous positions within the battery industry including research & development, product development, product engineering and independent consulting.

Mr. Coffman is a graduate of East Tennessee State University and the Southeastern School of Consumer Credit at Vanderbilt University.  He has held the position as vice-president in financial institutions related to consumer, mortgage and commercial lending.

It is with deep sorrow that we announce that Don passed away in January 2015 after a long battle with lung cancer.  Don was a valuable member of the HighWater team.  Our company started in Don’s workshop in 2010 and in the early days his contribution of working space, tools, and mechanical skill was critical in getting us off to a successful start.  But mostly he gave his energy, his great attitude, and his love for HighWater and what we are doing to make the world safer and greener. Don will be sorely missed.

The Royal Aeronautical Society has issued an update on their landmark report entitled "Smoke, Fire and Fumes in Transport Aircraft (SAFITA)". This revised report focuses on the growing threat of Lithium Battery fires and points to technology (aka PlaneGard) that is available to safely capture and contain burning PED's.
