4. General Guidelines to Anti-icing/Deicing Operations <br /> <br />The following list outlines basic decision making criteria, and lists some of the basic <br />operational functions to consider and/or follow when applying chemical anti- <br />icing/deicing agents or abrasives. <br /> <br />Weather factors: · Do not apply chemicals prior to forecasted rain <br /> · Do not apply chemicals if temperatures are above 32 F and steady <br /> · Do not apply chemicals in strong winds <br /> · Do not apply chemicals if rain is predicted before a snow storm <br /> · Use caution when anti-icing/deicing in warm conditions with low <br /> humidity as a chemical slipperiness condition may occur especially using <br /> heavier application rates <br /> · Do not apply CMA on a heavy snow or ice packs <br /> · Do not apply CMA in temperatures below 25 F. <br /> · Apply only abrasives in temperatures below 15 F <br /> · Residual effects can remain for up to several days after application of <br /> chemicals if precipitation does not dilute the initial application. <br /> Refreezing of the surface can occur when precipitation or moisture in the <br /> air dilutes the chemical on the surface <br /> <br />Operational considerations: · Always record time, location and rate of chemicals and abrasive <br /> application <br /> · Do not over apply chemicals within an intersection. <br /> · Avoid applying chemicals in heavy traffic. Application of anti- <br /> icing/deicing agents should be done if possible during slow commuting <br /> hours <br /> · Allows check spray operations prior to leaving Roosevelt facility <br /> · More is not always BETTER. High application rates can cause <br /> slippery conditions <br /> <br /> <br />
