• At times of maximum use of the resurfacing machine.
• At least once on Saturday or Sunday of each week that the arena is open to the public.
Ice Edging Measurements
Owners or operators must measure air concentrations at least once per week after using an internal combustion engine- powered ice edger. Measurements must be taken:
• Following maximum ice edger use at board height, inside the boards and at the centerline of the ice.
• Twenty minutes after completing edging if the arena building is open to the public when edging occurs, or before the public reoccupies the arena, if the arena is not open to the public when edging occurs.
Owners or operators may measure under an alternative schedule if approved by the commissioner.
Measurement Records A record of measurement findings must be kept and made available to the commissioner upon request. Before purchasing any device, you will want to make sure
the device can measure the concentrations that you set at your facility, and I suggest the following:
Air Quality Measuring Devices
Te owner or operator must demonstrate that the device and methods used to measure air quality conditions are accurate and reliable. Air quality measuring devices must be:
• Capable of measuring carbon monoxide air concentrations in a range of 0 to 100 parts per million (ppm) in increments of 1 ppm.
• Capable of measuring nitrogen dioxide air concentrations in a range of 0 to 5 parts per million (ppm) in increments of 0.1 ppm.
Te owner or operator must operate, store, maintain and
calibrate the devices according to the device manufacturer’s specifications. The owner or operator must also keep maintenance and calibration records.
Corrective Action
The owner or operator must take immediate corrective action when measurements of more than 20 ppm of carbon monoxide or more than 0.3 ppm of nitrogen dioxide are made in an area of the arena building that is open to the public. Corrective action must include increasing the ventilation rate immediately and suspending internal combustion-powered equipment.
