Current through Register Vol. 49, No. 13, September 23, 2024
Subpart
1.
Corrective action necessary.
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:
A. increasing the ventilation rate
immediately; and
B. suspending
internal combustion-powered equipment use.
The owner or operator 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.
Subp. 2.
Follow-up testing.
The owner or operator must conduct and document the following
air quality tests to confirm the effectiveness of the corrective action:
A. 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;
B. 20 minutes
after the next five uses of ice maintenance equipment; and
C. at least once per day for the subsequent
three days of arena operation.
Subp.
3.
Report.
Whenever corrective action is required under subpart 1, the
owner or operator must submit a report to the commissioner within five business
days that includes:
A. an explanation
of why corrective action was necessary;
B. a description of the immediate corrective
actions that were taken;
C. a
record of all air quality tests required by subpart 2; and
D. an action plan to prevent a
reoccurrence.
Subp. 4.
Arena evacuation necessary.
A.
The owner or operator must evacuate an area of the arena building whenever:
(1) measured carbon monoxide air
concentrations exceed 83 ppm or measured nitrogen dioxide air concentrations
exceed 2.0 ppm for more than five minutes;
(2) 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
(3)
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.
B. When evacuation becomes necessary, the
owner or operator must:
(1) contact the local
fire department as soon as possible to request assistance in evacuating the
facility and assessing the hazard; and
(2) contact the Minnesota Department of
Health upon completing evacuation.
C. The evacuated areas may only be reoccupied
by the public after an evacuation under item A if:
(1) acceptable air quality conditions are
measured;
(2) corrective measures
have been taken to prevent further incidence of unacceptable air quality
conditions; and
(3) acceptable air
quality conditions and corrective measures are verified by the local fire
department or the Minnesota Department of Health.
