Step by Step


Step 1

Following a few simple steps will make certain that your swimming pool is enjoyable and safe at all times. Always follow the chemical label instructions. Feel free to wear gloves, a mask and goggles when handling pool chemicals. Better safe than sorry.

Step 2

Chemicals should always be stored in the containers they came in. You should never put pool chemicals in another container. Doing so can cause an inadvertent chemical reaction.

Step 3

Pool chemicals should always be stored in a cool, dry, well ventilated location. I've heard stories of people fainting because they stored their chlorine inside of a garage (in the summer) and passed out because of the chlorine gas. Aside from being dangerous, chlorine gas can cause materials around it to become brittle and rust.

Step 4

Keep incompatible chemicals separate from each other. Liquids should not be stored on top of solids, acids should be stored away from chlorine, etc. Also keep the containers of of the floor if possible.

Step 5

Always reseal the lid to the containers after use. It only takes a drop of water to begin a chemical reaction with most pool chemicals. Also if the storage area can be locked, do so. This will prevent children and animals from gaining access to the area.

Step 6

Store pool chemicals away from a heat source, electric source or an area prone to flooding. Certain chemicals are oxidizers meaning they release oxygen. If a fire were to occur, it could quickly spread due to the abundance of oxygen the chemicals can release. If available, keep a copy of the MSDS (Material Safety Data Sheet) on hand.

Step 7

Lastly, make sure each chemical has its own labeled measuring cup. Measuring cups are inexpensive and provide an accurate way to measure your pool chemicals.

It's not clear why there's a hazard storing acid and chlorine in the same area if they're both enclosed in the plastic buckets they came in (lids on). Can you elaborate? Right now I have everything in an area in our garage.

If you mix muriatic acid and chlorine without diluting it with water, chlorine gas forms. If you have them tightly sealed and do not plan on opening them simultaneously or in the same space, you'll likely be fine. But generally, if a chemical compound's packaging says, "do not mix with (insert some other substance)," it's usually because something toxic or explosive happens if you do so.

Where do you store pool salt?

Hello Carpenter - The salt should be stored in a dry place like a shed, garage, or storage container.

I store my chemicals inside an outdoor plastic container all year round and the chemicals seem fine and I have done this for over 4 years now.

Yep, in Texas, it's hot inside and outside.
But it's hotter longer in South Florida...
I gotta go back to Long Island??

sam - Unfortunately, there is no good answer for this one in the southern states. The only cool and dry place is in your house and I would not store chemicals there. Next best is your garage but I'd do that on a limited basis mostly to keep the acid separate from the chlorine. Many people store their pool chemicals in a lockable plastic shed in the area around the pool.

The large plastic storage box, (approx.5ft.W x 5ft.H x 4’ft. D) Has a few metal pieces, how can rust be prevented? Thanks !!

You can try to spray the metal pieces with a weather coating or heavy-duty wd-40.
