Pool owners in Tucson love the benefits of a swimming pool. It provides relief from the sweltering heat and is a fun way to entertain family members and friends. However, those who own a pool have responsibilities, including storing the chemicals.
It's very important for pool owners to store their chemicals safely. Due to Arizona's dry conditions and high temperatures, improper storage could be very dangerous.
There are best practices, legal regulations, and great safety tips in this comprehensive guide. We have experts that can advise on common mistakes using pool chemicals.

Why Safe Storage of Swimming Pool Chemicals Matters
Arizona's extreme temperatures make it imperative to store pool chemicals properly. Different chemicals, like chlorine, algaecides, muriatic acid, and pH balancers are some of the pool chemicals that pool owners must use. They keep a pool clean and safe by killing bacteria, balancing pH levels, and controlling algae. Though they keep a pool safe, they are also hazardous materials, especially in a hot and dry place like Arizona.
If pool chemicals are not stored carefully, there could be consequences:
Explosions or fires due to chemical reactions
Toxic gas releasing from improperly combined substances
Health hazards like poisoning, respiratory issues, and burns
Environmental damage due to leaks
Arizona's extreme heat can exacerbate the risks, which make it even more dangerous to improperly store pool supplies, especially chemicals. When storing chemicals at home it may be beneficial to seek Residential Pool Service Tucson.
Different Types of Pool Chemicals
Before getting into the best storage techniques, it's important to know more about the different types of chemicals used in a pool:
Chlorine - Comes in various forms; tablets, liquid, and granular. It is used to disinfect the water.
Muriatic Acid - Also known as hydrochloric acid, it lowers both alkalinity and pH levels.
Sodium Bicarbonate - Raises alkalinity levels.
Calcium Hypochlorite - A highly reactive, dry form of chlorine.
Cyanuric Acid - This is important in Arizona, as it stabilizes chlorine due to effects of sun degradation.
Algaecides - Keeps algae under control.
Shock Treatment - Quickly sanitizes pool water.
Best Practices for Storing Pool Chemicals in Arizona
Choose a Proper Storage Location
The most important thing to remember is to choose a well-ventilated area as a pool chemical storage area. This should, ideally, separate from a garage or house. Many professional pool cleaners recommend a specific shed with windows/proper ventilation or an outdoor chemical storage area. It should also be kept away from ignition sources as fumes can be unsafe.
Keep Chemicals Cool and Dry
The high temperatures in Arizona can create a chemical reaction. The environment for storing chemicals should be below 95 degrees F, if possible. Metal buildings will make it hotter, so it's best to choose a different material. Also, don't forget to store the chemicals off of the floor; they could get damaged if there is a flash flood.
Use Original Containers
Never transfer pool chemicals from one container to another. The original containers from the manufacturer are best, because they resist corrosion. Also, for example, they come with safety details and chemical compatibility labels.
Separate Incompatible Chemicals
Speaking of chemical compatibility, make sure to read instructions about which chemicals should not be stored with others. For instance, muriatic acid should never be stored near products with chlorine.
Label Everything Clearly
Pool owners won't have to worry about knowing which chemical is which as long as they keep the chemicals clearly labeled. Also, keep in mind, that if there is a medical emergency with the chemicals, first responders will need to know which chemicals might be involved.
Use Secondary Containment
Place chemicals in plastic bins or trays to contain leaks or spills. This is particularly important for liquid chemicals like muriatic acid.
Keep Out of Reach
The last thing is to ensure children and pets cannot access pool chemicals. Store everything in a locked cabinet or shed with warning signs posted.
Specific Storage Concerns for Arizona
Heat Sensitivity
In high temperatures, some chemicals will begin to degrade. It's not uncommon for temperatures to reach well over 100 degrees F, so climate control and keeping the storage area cool is imperative.
Monsoon Season Risks
Arizona's monsoon season runs from June to September, and it comes with rainfall and sudden humidity, which is why it's vital to keep chemicals off of the ground and away from harm.
Sunlight Exposure
UV rays from the sun can break down chemical packaging over time and degrade the chemicals inside. Always store chemicals out of direct sunlight.
Legal and Environmental Considerations
Local Regulations
Arizona doesn't have specific laws about pool chemical storage, though general safety codes apply. These include EPA guidelines, local fire codes, and HOA regulations.
Disposal of Unused Chemicals
When a pool owner has to dispose pool chemicals, they should never dump pool chemicals down the drain or in the garbage. There are hazardous waste disposal centers in Tucson that can help get rid of these.
Emergency Preparedness
Even with the right storage and most careful considerations, accidents can happen. Here are some best practices for what to keep around the chemicals:
A Class B/C fire extinguisher for chemical fires
First aid kit with eye wash and burn cream
Emergency contact list with poison control and fire department contact information
PPE like goggles, masks, and gloves

Common Mistakes to Avoid
Never mix chemicals, especially chlorine, with other chemicals
Storing chemicals in an area that is not ventilated can lead to toxic fume buildup
Transferring chemicals to other containers can cause accidents and confusion
Neglecting to notice expiration dates can lead to unstable chemicals
Pool Maintenance Companies and Chemical Safety
Using a pool maintenance service in Arizona is always a good idea, but it's important to ensure they’re certified and follow safe chemical handling practices. Don’t assume they’ll follow proper storage protocols—ask where they store chemicals and what safety measures they take.
