1 It is recommended that all of the equipment used as described above be moved on pneumatic tires. J.IiGS, STUDS AND CHAINS WILL DAMAGE THE SURFACE AND SHOULD NOT BF US D, Snow removal equipment may be stopped momentarily on the turf surface, but DO NOT PA • K SLi N i UIPMENT ON THE FIELD OVERNIGHT OR FOR SEVERAL, HOURS- Tire pressure should be below 35 psi. Important: Keep tarps or field covers off the field in freezing weather. Tarps and covers can freeze to the turf by means of condensation and thus can be very difficult to remove for a scheduled event. Ice Renwval: In some cases it will be desirable to go over the field with a lawn roller or rotary street broom to break up and sweep away frost or ice. If the day is sunny and the frost or ice is not excessive, it tends to melt readily over synthetic surfaces,especially with player foot traffic to aid the process. In the event of extreme cold weather and a heavy layer of ice, there is little choice but to use chemicals to assist in getting rid of it. Remember, any ice-melting chemical put on the field will leave residue that may leave the turf slippery or sticky. Such residue should be washed off the turf as soon as weather permits. Many chemicals commonly used for ice melting (rock salt, ammonium nitrate and calcium chloride) are irritating to human skin, corrosive to equipment or harmful to synthetic turf These chemicals should NOT be used on the GeoGreen or GeoTrax surfaces. The only ice-melter found to date that is safe, inexpensive and non-corrosive is.fertilizer grade urea.* When a surface has been subjected to a freezing rain or is heavily frostcoated, thawing can be hastened by broadcast application of pilled, fertilizer grade urea The spread rate will be determined in some measure by the amount of ice present,but 100 pounds per 3000 square feet is a good starting point. After spreading,the urea should be allowed to remain in place for half an hour or more to melt the ice. It should then be removed from the field (along with the water it has picked up) with a squeegee. Urea will be less effective as the temperature drops below 10 to 12 degrees F and it is ineffective below 0 degrees F. A thick residue of urea will be left behind after the field has been gone over with a squeegee or ' swept. In wet weather this film will make the field somewhat slippery. As soon as the danger of a hard freeze has past, the field should be washed down with liberal amounts of water to remove traces of the urea. WARNING: DO NOT USE COMMON SALT, ROCK SALT, CALCIUM CHLORIDE; t AMMONIUM NITRATE or any other corrosive or irritating chemicals to melt ice on playing surface as they may damage equipment, harm personnel or the turf. ' *Urea may be a mild eye irritant. If it gets into a person's eye, it should be washed out with liberal amounts of water.
