Using and Storing Chemicals

Water treatment chemicals are concentrated and potent substances. They can react violently with many common household chemicals and with each other, and must be stored with care.

Safe Chemical Storage

Pool and spa chemicals should be kept in areas that are cool, dry and lockable. The chemicals must be kept away from petroleum products, such as grease, oil, petrol or liquid detergents. They should also not be stored with acids, alcohol, cleaners, soap powders or small quantities of water.

Liquid chemicals should be stored within an isolation bund that can contain any leakages of the material, and prevent chemicals from mixing in the event of a spill.

Safe Chemical Handling

Pool and spa chemicals also need to be handled with care.

• Only buy quantities you can use within the use by dates on the containers.

• Read and follow instructions carefully. If you do not understand something, ask the retailer or pool chemical specialist.


• Use only clean, DRY, non-combustible measuring scoops made from porcelain, recommended plastics or metal. Use separate scoops for each chemical.

• Add chemicals to water. DON’T POUR WATER ONTO CHEMICALS.

• Wash any spilt chemicals off clothes or skin at once, using plenty of water.

• If chemical is spilt, splashed, or wiped into an eye, flood the eyeball with clean running water and get to a doctor or hospital immediately.

• Dispose of water testing samples and spilt chemicals safely by diluting with water and disposing into the garden. They should not be put back into the pool.
