(a) Corrective action necessary. The owner shall 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:
(1) Increasing the ventilation rate immediately; and
(2) Suspending internal combustion- powered equipment use.
The owner must continue corrective action until measurements show not more than 20 ppm of carbon monoxide and not more than 0.3 ppm of nitrogen dioxide in all areas of the arena building that are open to the public.
(b) Follow-up testing. The owner must conduct and document the following air quality tests to confirm the effectiveness of the corrective action:
(1) At board height, inside the boards, and at the centerline of the ice;
(2) At 20-minute intervals until measurements show not more than 20 ppm of carbon monoxide and not more than 0.3 ppm of nitrogen dioxide;
(3) Twenty minutes after the next five uses of ice maintenance equipment recorded in the log; and
(4) At least once per day for the subsequent three days of arena operation.
(c) Report. Whenever corrective action is required, the owner must submit a report to the AHJ within five business days after the corrective action was taken that includes:
(1) An explanation of why corrective action was necessary;
(2) A description of the immediate corrective actions that were taken;
(3) A record of all air quality tests required; and
(4) An action plan to prevent a reoccurrence.
(d) Arena evacuation necessary.
(1) The owner must evacuate an area of the arena building whenever:
A. Measured carbon monoxide air concentrations exceed 83 ppm or measured nitrogen dioxide air concentrations exceed 2.0 ppm for more than five minutes;
B. Measured carbon monoxide air concentrations exceed 40 ppm or measured nitrogen dioxide air concentrations exceed 0.6 ppm for more than one hour after originally measuring unacceptable air quality conditions; or
C. Measured carbon monoxide air concentrations exceed 20 ppm or measured nitrogen dioxide air concentrations exceed 0.3 ppm for more than two hours after originally measuring unacceptable air quality conditions.
(2) When evacuation becomes necessary, the owner must contact the Village of Evendale Fire Department as soon as possible to request assistance in evacuating the facility and assessing the hazard. If the owner is not available, the owner must designate a responsible person to contact the Village of Evendale Fire Department as soon as possible to request assistance in evacuating the facility and assessing the hazard.
(3) The evacuated areas may only be re-occupied by the public after an evacuation if:
A. Acceptable air quality conditions are measured;
B. Corrective measures have been taken to prevent further incidence of unacceptable air quality conditions; and
C. Acceptable air quality conditions and corrective measures are verified by the AHJ.
