Never mix chemicals.

[JamesW]

Never mix different chemicals together.

Mixing different chemicals can create very dangerous, toxic and explosive results.

Mixing calcium hypochlorite with anything is one of the most dangerous types of mixtures.

Finally, if the choice is to alternate between stabilized and unstabilized chorine, they should not be stored near each other. The reaction of an isocyanurate with hypochlorite can result in rapid formation of nitrogen trichloride, which at high enough concentrations will combust spontaneously with great violence.

Even when you think that the chemicals are the same, it's better to add them separately just to be safe.

Unless something comes from the same container, it should be kept separate from anything else.

Mixing chemicals from different containers always risks the chance that they could be different.

Take time to review the safety of how you store and use chemicals.

Make sure that the chemicals are not accessible to kids.

Never use chemicals in a feeder that are not intended for the feeder.

Make sure that everyone has basic safety information for handling chemicals or responding to a spill or accident.

Mixing calcium hypochlorite with anything is one of the most dangerous types of mixtures.

Mixing chlorine and acid is another very dangerous mixture.

Always keep any form of chlorine and any acids stored in different locations.

And add chlorine and acid to the water at least 15 minutes apart.

Always add chemicals to water. Never add water to chemicals.

Granulated calcium is exothermic and will generate enough heat to burn if added to a small amount of water. Be careful when dissolving calcium to make a slurry to add to the pool. It is safer to add calcium directly to the pool.

For commercial pool operators, please make sure that the employees are well trained and supervised regarding chemical safety.

Sometimes people want to add different chemicals to their feeder that are not intended for the feeder.

This can cause the feeder to explode.

For commercial pool operators, please make sure that the employees are well trained and supervised regarding chemical safety.

Not just commercial pool operators, for residential pools please make sure that everyone in the family who may handle chemicals are well trained and supervised regarding chemical safety. Especially if you ask teenagers to do pool maintenance.

Especially if you ask teenagers to do pool maintenance.

Irresponsible teenagers?

Well, that seems unlikely.

This thread should be pinned somewhere. Super important for new pool owners.

I’ll add the possible downfall of changing containers as well. You may know what’s what, but if anybody else grabs a jug/box it may not be what they think it is. Be it your significant other or a teenager.

I am going to write it up as Chemical Safety in the Wiki soon.
