Are you aware of the dangers of chlorine gas in swimming pools? This is of particular concern when stopping and starting a commercial swimming pool treatment system. You might think it’s a small issue, but the truth is, it can be very hazardous. Let’s dive deeper into this topic and explore the issues at hand.

When the circulation pumps are running, water flows through the pipework. However, when the circulation pumps are switched off, the flow of water stops. This can cause a dangerous situation because the chemicals being injected into the system can mix within the pipework. It’s crucial to check that the chemical dosing system has stopped dosing when the pumps are turned off. Never assume that the auto-shut-off system will always work, as it can and does fail.

There is a risk of extremely hazardous chemicals being generated and emitted when the power to the circulation pumps is cut intentionally or due to power failure. Restarting the system following a failure of the circulation system while there are people in the pool should never be attempted. It’s important to keep the circulation and chemical dosing systems stopped if there is a concern that there may have been inadvertent mixing of chemicals within the pipework. In such a situation, it’s advisable to contact the fire service.

After restarting the system, you must ensure that the chemical levels are within acceptable ranges. To do this, you should carry out tests for Free Chlorine, Combined Chlorine, pH, and Total Dissolved Solids. By doing so, you’ll be able to ensure the safety of everyone using the pool.

In conclusion, it’s vital to be aware of the hazards associated with stopping and starting a commercial swimming pool treatment system. Always take the necessary precautions to prevent any accidents or mishaps. Remember to check the chemical dosing system and carry out tests for chemical levels after restarting the system. By doing so, you’ll ensure a safe and enjoyable swimming experience for all.
