AIR QUALITY
open to the public. Such conditions shall be defined as: one-hour average air concentration of not more than 20 parts of carbon monoxide per one million parts of air by volume (20 ppm), and one-hour average air concentrations of not more than 0.3 parts of nitrogen dioxide per one million parts of air by volume (0.3 ppm). In order for your staff to understand the importance of air
quality conditions, you will need to educate and train them in all aspects of the guidelines you establish, whether or not they are based on another state’s guidelines. Te guidelines in Minnesota are as follows: Te owner or operator must ensure that a trained responsible
person is available in the building at all times the arena is open to the public. Tis individual must be trained in the following: acceptable air quality (current limits for both CO and NO2
);
methods of obtaining acceptable air quality; how to contact the person who conducts the testing; location of air quality readings; proper operation and storage of the arena air quality measuring device; proper collection of air samples with the arena air quality measuring device; appropriate actions for correcting unacceptable air quality; record-keeping requirements;
documentation; and signs and symptoms of CO and NO2 poisoning. Tis individual must also be on call and able to arrive at the arena quickly. He or she must acknowledge, with their written signature, that
they have received training meeting the requirements outlined. Owners or operators must maintain the written acknowledgment.
Measuring Air Quality
When measuring air quality, you can follow these proven steps to produce the most accurate readings for your facility. Mount monitors on the walls in your bleacher area or by your resurfacer door to monitor air quality levels; keep in the mind that they won’t give you accurate readings of levels inside dasher boards and at ice level. Owners or operators of indoor ice arenas must measure
carbon monoxide and nitrogen dioxide air concentrations in each arena when internal combustion engine-powered ice maintenance equipment (ice resurfacer or ice edger) is used. An individual who has received proper training must make measurements.
Ice Resurfacing Measurements
Owners or operators must measure air concentrations at least twice per week after using an internal combustion engine- powered ice resurfacer.
Measurements must be taken: • At board height, inside the boards and at the centerline of the ice.
• Twenty minutes after completion of resurfacing unless the commissioner has granted the operator approval to measure under an alternative schedule.
