(R) Liquid Runway Deicing/Anti-Icing Product
|Publication Date:||1 November 2018|
This specification covers runway deicing and anti-icing products in the form of a liquid. Unless otherwise stated, all specifications referenced herein are latest (current) revision.
These products have been used typically at airports on runways, taxiways, and other aircraft maneuvering areas for the prevention and removal of frozen deposits of snow, frost, and ice, but usage is not limited to such applications. These products must not be used to deice/anti-ice aircraft.
While this specification covers technical requirements for liquid runway deicing/anti-icing products, it does not address the compatibility issue of combining runway deicing products during the operational phase. Products meeting this specification are unique to each manufacturer and could be adversely affected by mixing with other deicing/anti-icing products. It is the user's responsibility to become familiar with the safe and proper use of applying multiple deicing/anti-icing products.
Diluting a Liquid Runway Deicing Product
If the liquid deicing/anti-icing product is diluted and subsequently used as a liquid deicing/anti-icing product on runways, taxiways, and other aircraft maneuvering areas, the resulting liquid shall meet the latest edition requirements of AMS1435.
Pavement Friction Evaluation
Airport authorities should ascertain the friction coefficient of the runway after the application of deicing/anti-icing product prior to aircraft landing operations.
Caution should be exercised in the use of glycol-water deicing/anti-icing products in and around aircraft electrical/electroni
Airport authorities are advised that runway deicing 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 that 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 products may be mildly toxic and contact with human skin and eyes should be avoided. Prolonged exposure to concentrations of vapor and wind-borne 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.
