Minimize the different types of chemicals you store.
Don't buy more than you will consume in a season. Some of the more hazardous pool chemicals don't keep well.
Keep wet hands and dirty scoops out of your chemicals. Contamination is often a cause of problems.
Don't store pool chemicals where other materials can fall into them.
Never, NEVER, NEVER, mix chemicals. When adding chemicals to your pool allow one to disappear before adding another.
Use gloves and glasses.
Make sure chemicals are locked away from small children.
Always label containers
ALL forms of acids react DANGEROUSLY with all forms of chlorine or bromine. Never, never, NEVER mix
swimming pool chemicals of any type! Chlorine compounds that look or smell alike may not be the same: you have to know
the actual chemical. Allowing even small amounts of different chlorine sanitizers to touch each other can be REALLY
dangerous. In particular, trichlor and calcium hypochlorite can react dangerously on contact with each other. Once they're
dissolved in the pool, though, they get along fine.
