Before the Storm Use wisely. Chlorides can increase the salinity of soil, which can lead to compaction and erosion. • Apply an anti-ice product during non - rush -hour traffic pe- riods. • When frost on the shoulder starts to move into the travel lanes, reapply anti-icing product. What not to do • Don't anti-ice under blowing conditions, in areas prone to drifting, and anywhere else you would refrain from using salt. Be aware of areas that are prone to wind issues. • Reapplication isn't always necessary if there is still a re- sidual. The residual effect can remain for up to five days after application if precipitation or traffic wear -off does not dilute the initial application. • Remember that the surface can refreeze when precipita- tion or moisture in the air dilutes the chemical. • Don't apply MgC12 or CaC12 to a warm road (above 28° F pavement temperature). It can become slippery and cause crashes! • Don't apply before predicted rain. • For the first application or after a prolonged dry spell, ap- ply liquids at half the rate (not half the concentration). On dry roads, liquids tend to mix with oil from vehicles and cause slippery conditions. • Don't apply too much or the roadway may become slip- pery. Less is better. Always follow application recommen- dations. Equipment • Anti-icing unit, i.e., transport vehicle with tank. • Fan spray is not recommended. 6 • • •
