Ice Arena CO & NO2 Monitoring

Developed specifically for ice arenas, the Aretas CO / NO2 monitoring system provides you with alerts and other useful data required by many states or provinces. If CO or NO2 reach levels of concern, your team will be notified by email and/or text so you can take immediate action!

As an added benefit, all systems come with Temperature and Relative Humidity monitoring, offering you energy savings opportunities at no extra-cost!

We even offer automated controls to turn on your ventilation system when levels are exceeded, call to find out more today.

Not only is CO & NO2 monitoring the right thing to do, but in many states it is required by law. As an example, Minnesota is at the forefront of public health by requiring sports arenas to continuously monitor AND document CO & NO2 consentration. Many facilities, and even other states follow the Minnesota guidelines outlined here and states "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."

Save Money
Our continuous monitoring system, with online reporting and download capabilies means your team doesn't manually measure air quality levels many times per week. They can then print and file reports to meet time consuming reporting protocols.

Temperature and Relative Humidity are included at no extra cost, so that you can optimize your user comfort levels, while taking advantage of energy savings opportunities. Our online analytics charting allows you to understand your facilities mold index which shows when temperature and relative humidity levels may be causing mold growth.

Continuous CO & NO2 monitoring that includes
  • 24/7 data and alerts via text and email
  • Wireless system for simplified installations
  • Archived data allows reporting anytime you need
  • Optional controls automates ventilation when needed
Ice Arena Monitoring Package
Suggested coverage requires at least 3 monitors. One mounted in the stands, one at the red line and one in the resurfacer area. Depending on your facilities size, you may prefer additional coverage in public spaces such as the concessions area.
Positive PR
Sharing your proactive monitoring efforts with the public gives them peace of mind and shows you care.

Monitor and Control equipment with your wireless sensor
Turning information into action! With Aretas’ industrial wireless relay controls we can expand your online data analytics system capabilities.

With the addition of the relay controller on one or more of your sensors you can set a variety of automatic ‘actions’; a fan turns on, a compressor starts, a refrigerator cools, even HVAC remote control. For more information about wireless industrial relay controls click here or contact your live Aretas representative today for a free demo.

“It stands as one of the most important and interesting projects I have done for the ice arena. The general public has no idea what has gone on behind the scenes but I take satisfaction in knowing we have done our best to protect the health of our skaters.”

Why monitoring is important

There have been regular occurences of CO/NO2 issues in the news as any online search will show. As an example from Canadian Worksafe BC "In two separate incidents, arenas were evacuated after children were exposed to carbon monoxide while skating.

At one arena, children began to feel ill and two children fell into a state of semi-consciousness. During the emergency evacuation, firefighters took air samples and found carbon monoxide levels as high as 264 parts per million. The suspected source of the carbon monoxide is an ice resurfacer that had mechanical problems.

In the second incident, several minor-league hockey players were taken to hospital with signs and symptoms of carbon monoxide poisoning. A scissor lift used earlier in the day inside the arena is the suspected source." WorkSafeBC

In The News
Is the ice rink making your child sick?

NBC’s Jeff Rossen investigates air quality at ice rinks, where toxic pollutants, such as carbon monoxide, may be lurking.

Who is at risk

According to the IIHF (International Ice Hockey Federation), in Canada there are 13451 ice rinks and in the USA there are 2075 member ice rinks. Together, they service almost 1 million registered players. If you combine this number with the numerous other user groups such as public skating, figure skating, speed skating, non-registered hockey leagues, ringette, curling, and a wealth of other private rental activities we can see that the effected user group is vast.


“Carbon monoxide (CO) gas is one of the most widespread and dangerous industrial hazards. It is the most common cause of occupational gas poisonings leading to death. It can be lethal at concentrations as low as 1000 parts per million (ppm).”  Work Safe BC. Unintentional CO exposure accounts for an estimated 15,000 emergency department visits and 500 unintentional deaths in the United States each year according to the CDC.

  • Carbon monoxide is an odorless, colorless gas often formed in the process of incomplete combustion of organic substances, including fuels. It is dangerous because it interferes with normal oxygen uptake for humans and other living organisms needing oxygen to live.
  • Nitrogen dioxide is a highly reactive oxidant and corrosive gas. It is formed as a byproduct of combustion. Exposure to nitrogen dioxide can irritate the eyes, nose, throat, lungs, and lower resistance to respiratory infections. People with existing respiratory illness such as asthma are at increased risk for these health effects. Arenas are required to keep concentrations of nitrogen dioxide at or below 0.5 ppm in the air.
