Kelso Technologies Inc. (TSX VENTURE:KLS)(OTCQX:KEOSF) - The Company reports
that it has filed a patent application for a new externally mounted dual rating
pressure relief valve ("DPRV") design for use on new rail tank cars and
retrofits of existing rail tank cars. 


Recent derailments of trains carrying hazardous materials have raised US and
Canadian government concerns over railroad safety. Regulatory bodies are focused
on finalizing design criteria for safety enhancements to existing railroad tank
cars carrying flammable liquids including crude oil and ethanol. These concerns
center on the quality and effectiveness of service equipment including pressure
relief valves used for containment of hazmat during rail operations in both
non-accident and accident events. 


Kelso has initiated a proactive design strategy based on these regulatory
concerns and as a result we have created a new DPRV design that based on
mechanical engineering innovations that provide safety benefits in both accident
and non-accident environments. In general terms in an accident involving fire
the DPRV will significantly lower its operating pressure rating to a level that
will keep the valve open in order to evacuate the tank car in less than 100
minutes as required by AAR recommendations. This is a dramatic change to current
technology capability. In addition, Kelso believes the DPRV will provide
economic advantages to the impact of the expense of retrofits facing the
railroad industry.


The patent has been filed under a "Non-Publication Request" which keeps the
patent filing private until the patent is issued. We have done this for
competitive reasons as keeping our invention out of the eyes of our competition
until we launch the commercial product carries various market advantages for
Kelso. Our competition will most likely become aware of our DPRV when we submit
our Application for Approval to the AAR, however they will not have enough
details on the design to allow them to try to circumvent our ideas. The final
patent will likely take 2 years or more to be granted and carry a 17 year life
starting from the date the patent is granted.


The DPRV will enter Association of American Railroads (AAR) approval process
shortly after the prototypes are completed in May 2014. The Company will
announce AAR approvals by press release when they are received.
