Never store pool chemicals in old food or beverage containers. This creates a risk of accidental ingestion and often doesn’t provide the chemical resistance required to store harsh pool products safely.
Plastic Tubs and Labeled Bins
Plastic bins with tight-fitting lids are ideal for housing multiple smaller chemical containers. Use clear labeling and separate bins for each class of chemicals.
Metal vs. Plastic Storage Box
While metal storage boxes may seem durable, they are not advisable for pool chemicals as they may rust or corrode when exposed to chemical vapors. It’s safer to use non-corrosive plastic or polyethylene storage containers.
Preventing Pool Chemical Reactions
Chemical reactions during storage can be dangerous and even deadly. Understanding incompatible chemicals and using simple isolation methods helps prevent unwanted events.
Check for Chemical Incompatibility
Some chemicals shouldn’t be stored near one another. Incompatible products include:
| Chemical A | Chemical B | Potential Reaction |
|---|---|---|
| Chlorine | Muriatic Acid | Release of toxic chlorine gas |
| Bromine | Ammonia | Fire or explosive reaction |
| Oxidizers | Acids | Fire and hazardous fumes |
Use Physical Separation
In storage, even within the same cabinet or shed, incompatible chemicals should be physically separated. Options include:
Label each section clearly to avoid confusion and prevent mix-ups.
Common Mistakes to Avoid in Pool Chemical Storage
Despite the awareness around chemical safety, several common mistakes occur among pool owners.
