Disease transmission prevention
- Use registered disinfectant/sanitiser
- Follow the label directions and maintain the specified level of disinfection at all times
- Maintain the water’s pH to a compliant standard such
- as slightly alkaline reading (7.2 - 7.4)
- Perform regular oxidation and water replacement
- Even when a pool or spa is not in use, it is important to maintain a sanitiser residual and to provide circulation to move the sanitizer throughout the system.
- Features that have been out of operation even for a short time should be cleaned, treated, and adequately flushed before use.
- Reduces liability
- Reduces operational costs
There is a Hazard Guide that provides OH&S standards for recreational water
- Untreated pool water is an environment that encourages the rapid growth of organisms. Continual treatment of this water is necessary to prevent the development of a health hazard.
- Water quality must equal or exceed the standards set by the standards.
- The indoor aquatic environment will develop airborne contaminates if proper water treatment and air exchanges are not maintained.
- The amount of fresh air that must be introduced to prevent health problems is dependent upon design and usage patterns.
Indoor Air Quality
- An employee’s designated position within a facility can result in increased exposure.
- Similarly, individuals pre-disposed to respiratory disease are at higher risk in improperly designed or poorly operated aquatic facilities.
Exposure to respirable aerosol particles
- Compared to background levels in air:
- fountains and waterfalls have been shown to cause a 1.4 fold increase in respirable aerosol particles
- the addition of a slide or flume causes a 2.3 fold increase
- the use of multiple spray devices in a facility can result in a 5.2 fold increase in respirable particle levels, and an 8 fold or greater increase in endotoxin levels.
- Ventilation system
Chlorine Gas Exposure
Chlorine and acid are common chemicals used in aquatic facilities. When injected individually into an operating circulation system, these chemicals must enter the water in a safe and controlled manner.
Failure of a circulation pump while chemical pumps remain active will result in chlorine and acid coming into contact prior to dispersion. This results in chlorine gas being created and released into the facility when the circulation systems comes back on-line. Staff and patrons in the facility will suffer from breathing difficulties and chemical burns to the respiratory system.
