Maintenance Level Guidelines
Daily Ice Rink Condition Criteria
Excellent
—
“Perfect” Ice; smooth as glass. Imperfections* less than 10% of ice surface and no snow cover – 4” minimum.
Good
— Imperfections* 10-50% of ice surface; rest of ice in excellent condition. No snow cover.
Fair
—
More than 50% imperfections* in ice surface or snow cover on ice.
Poor Ice surface very rough, but still skatable – not dangerous. No Skating — Lack of ice, or condition of ice unsafe for skating (i.e., thin ice, standing water or extremely rough surface). DANGEROUS *Imperfections: Defined as ripples, rough areas, “boils” or other flaws that DO NOT hinder skating. __ Removing Snow From Rinks Always check thickness of ice in warmer weather (above 30 ° ) before driving equipment on ice. Ice must be 4" minimum ice thickness to allow equipment (rider units) on ice. Method of Measurement: Drill 6” holes minimum (with a ½” drill bit) in 3 to 4 locations in each rink. Measure by placing a pencil marked in ½” intervals in drilled hole. Unless directed by a supervisor, only use the following equipment: walk-behind hand blower and Ariens sweeper. Do not take a chance with riding equipment. Falling through the ice not only damages the ice, but causes costly repairs to our equipment. Breakthrough may occur, usually on north end of hockey rinks. Always start in the middle of the rink and run lengthwise, pushing snow/ice shavings to the side. For hockey rinks, shovel out all snow/ice shavings that have been pushed to the sides. Always clear a path to and from the rinks with equipment for easy maintenance access. Never hit hockey boards with equipment, as it will damage the equipment and the boards. Always follow the instructions regarding hydrant shut off.
