Storage of swimming pool treatment chemicals
Pool treatment chemicals such as chlorine are hazardous substances and must be correctly stored and secured away from other chemicals.
Make sure you have separate secure storage for each chemical that you use so they are safely away from child access or potential contamination by other substances i.e., oil, petrol, diesel etc.
When emptying your chemically treated pool, empty it into the Council sewer and not the storm water system to prevent sea and water way pollution.
Disposing of hazardous substances
Dispose of unwanted hazardous substances or chemicals i.e., paints, chemicals, car batteries, biological waste etc in a responsible and safe manner.
Do not dispose of them in storm water, other open or closed drains or waterways or burn them. Do not dump them in any landfill tip without first obtaining expert advice to ensure that it is safe to do so.
