Form This specification covers deicing and anti-icing materials in the form of a fluid. Application This deicing/anti-icing fluid has been used typically on runways@ taxiways@ and other aircraft maneuvering areas for the prevention and removal of frozen deposits of frost and ice. Fluids must not be used to deice/anti-ice aircraft. Precautions Material Compatibilities While this specification covers technical requirements for fluid deicing/anti-icing materials@ it does not address the compatibility issue of combining deicers/anti-icers during the operational phase. Fluids meeting this specification are unique to each manufacturer and may be adversely affected by mixing with other deicing/anti-icing fluids. It is the user's responsibility to become familiar with the safe and proper use of applying multiple deicers/anti-icers. Pavement Friction Evaluation Airport authorities should ascertain the friction coefficient of the runway after the application of deicing/anti-icing fluid prior to aircraft landing operations. Caution should be exercised in the use of glycol-water deicing/anti-icing solutions in and around aircraft electrical/electronic circuitry with noble metal coated wiring or terminals which could come into contact with the fluid. Exothermic reactions@ which may result in fire@ have been reported. This may occur where defectively insulated wires@ switches@ or circuit breakers carrying direct current are encountered. Deicing/anti-icing fluids based on glycols should contain an inhibitor to minimize this potential fire hazard (3.1). Airport authorities are advised that fluid products can cause failure of runway and taxiway lighting circuits. Damage potential depends on the condition of these systems@ quantity of product usage@ or the opportunity of product entry into electrical conduit systems. A comprehensive evaluation of the aeronautical lighting systems should be completed as part of winter operations planning. Safety - Hazardous Materials While the materials@ methods@ applications@ and processes described or referenced in this specification may involve the use of hazardous materials@ this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved. Some deicing/anti-icing formulations may be mildly toxic and contact with human skin and eyes should be avoided. Prolonged exposure to concentrations of vapor and windborne mists should be avoided. Prolonged exposure to concentrations exceeding any established threshold limit values (TLV) for those products or its major components should be avoided.
