The halls are used mainly for sports and hobbies, but also for concerts, exhibitions, and trade fairs.
The annual number of visitors in larger ice halls may rise to several millions annually, and therefore the safety instructions are important to guarantee the required safety and security levels.
Continuous gas monitoring and alarms of technical faults, process disturbances, gas leaks in ice machine room are important.
Battery charging (hydrogen monitoring)
Many ice rinks have battery-operated ice machines. The number of battery machines is constantly increasing in both new and old halls.
During charging, explosive hydrogen gas (H2) may be formed, which when mixed with air forms an explosive mixture.
Swimming pools (water treatment, O3, Cl2 and HCl)
There is always a risk of ozone, chlorine and hydrogen chloride (hydrochloric acid) leaking in the chemical storage facilities of water treatment facilities.
Leakage situations quickly result in alarms in the monitoring system and applied alarm targets.
In addition to alarms, the device can control emergency room ventilation or other actuators.
Microcar tracks and motocross halls
On indoor tracks, high concentrations of carbon monoxide and nitrogen oxides (NOx) and hydrocarbons (HC) in the exhaust gases pose significant health risks to both competitors and spectators.
Carbon monoxide is an odorless, tasteless, invisible and very dangerous gas that causes headaches, dizziness and paralysis of the feet, even at low concentrations. At higher concentrations, carbon monoxide is a deadly gas.
