FAA Disclaimer: The Energy Institute (EI) produced the video. The EI is a non-profit chartered professional membership body, based in the United Kingdom, that brings together professionals working globally across the energy sector. The body works to address global challenges and uses their skills and knowledge to suggest safety practices that also protect the environment. The FAA encourages users of the aviation system to clearly and safely label Diesel Exhaust Fluid and Fuel System Icing Inhibitor and keep them stored in separate areas, to avoid any accidental mixing of fluids.
