The chemicals used within Plant rooms associated with swimming pools and spa pools have the potential to create toxic atmospheres in the event of a spill or misuse. Two of the most commonly used chemicals in Pool Plant Rooms are Sodium Hypochlorite and Hydrochloric Acid. Sodium Hypochlorite is commonly used as a disinfectant, whereas Hydrochloric Acid is used to control the pH value of the water.
In the event that Sodium Hypochlorite, through accident or mis-handling, comes into contact with an acid, the result is the creation of Chlorine Gas. Chlorine Gas is potentially very harmful in small does so early detection is vital, particularly as many pool plant rooms are small, confined spaces often with poor natural ventilation.
Additionally, Ozone may be used as a disinfectant and activated carbon or CO2 gas may be utilised as part of the pH control system. As with Sodium Hypochlorite and Hydrochloric Acid, both Ozone and activated carbon (through the potential to generate Carbon Dioxide) have the potential to create toxic atmospheres.
Common Swimming Pool Applications
Gas detection is frequently provided with pool plant rooms to monitor for the presence of Chlorine Gas and/or Carbon Dioxide (depending upon the chemicals used in the water treatment process). Detectors will be installed close to the points where chemicals may be mixed, or added into the dosing process, to provide the earliest possible warning of a toxic atmosphere.
The Frontline Safety team will be on hand to advise on the positioning of sensors, suitable controllers and any other questions you may have on this particular application.
Gases commonly found in the Swimming Pool water treatment industry include:
Chlorine, Carbon Dioxide, Ozone.
