Pool Chemical Storage Tips

If you’re a pool owner, you may have a dedicated space where you store your chemicals. The space you choose may not seem like a big deal, but did you know that if not stored properly, the most common pool chemicals have the potential to react in a hazardous way that can be detrimental to you and your family? Let’s go through the risks and how to avoid these accidents at home.


Many pool chemicals exhibit oxidation properties which make them highly reactive, especially if they reach high temperatures, causing toxic vapors to emit if not properly stored. A partial listing of common pool chemicals includes chlorinated isocyanurates, lithium hypochlorite, sodium bicarbonate, potassium monopersulfate, hydrogen peroxide, sodium hypochlorite, calcium hypochlorite, and certain ammonium, brominated, copper and silver compounds, and muriatic acid.

Higher risk chemicals include those that are mixed with chlorine or a chlorine ion that are added to pool water to control the bacteria levels. Oxidizers are chemicals that release chlorine into your pool. Common oxidizers include calcium hypochlorite, sodium hypochlorite, and chlorinated isocyanurates.


While pool chemicals were designed to work within large bodies of water, a small amount of water can cause an unwanted reaction. It could potentially cause a chemical to increase in temperature or even emit a hazardous gas. Typical reasons for water leaks that might make contact with chemicals include roof leaks, wet floors, or leak from a broken/poorly sealed window. Even extreme humidity can play a part in putting your chemicals at risk.

Improper mixing can also cause adverse reactions. This can happen if a chemically contaminated tool or equipment is used to mix another chemical. Also, common spills or improper chemical disposal can cause unwanted mixing which can cause unwanted risks.


As mentioned above, trouble ensues when moisture comes in contact with pool chemicals, so it’s important to keep them in a cool, dry environment. Here are a few tips for keeping your chemicals safe and sound.

Safeguard Your Storage Area

Check the roof for leaks

Store chemicals away from windows and doors

Check doors and window for cracks or potential leaks

Avoid storing food or drink in the same area as your pool chemicals

Consider investing in a shelf system to keep the chemicals off the ground

Inspect Chemical Containers

Check the package for any leaks or cracks

Properly discard or cover damaged packaging

Consider waterproof covers to keep water out of the packaging

Avoid Chemical Mixing & Contamination

Don’t mix old and new chemicals

Separate chemicals that are likely to react to one another

Designate tools for specific chemicals to avoid contamination

Keep all combustible or flammable substances away from the storage area

Even with the precautions above, if you find yourself dealing with a chemical fire or an adverse reaction has occurred, always call 911.
