WE CARE ABOUT
TRIFIRE solutions for both basic and advanced training use normal bottle gas (propane/butane). It is non-toxic and not an environmental hazard even if released as a liquid or vapor into water, air or soil. Propane is also clean burning. That is why forklifts used indoors throughout the world are propane powered.
Combustion does produce greenhouse gases, but levels are far below that of any readily available carbon-based fuel (diesel, kerosene etc.).
