Pool chemicals - store chemicals safely

Besides the fact that they are directly poisonous if consumed or inhaled in large amounts in their concentrated state, swimming pool chemicals can turn into explosives or damage items around them. They can even ultimately harm you or your family.

Pool chemicals are oxidizers and corrosives.

Oxidizing materials (e.g. calcium hypochlorite) can easily react chemically to burnable materials such as petrol, hydrogen and ethanol. If these materials are kept together in your garden shed or garage the chance of a fire or explosion increases. This reaction can happen all of a sudden at either room temperature or if the temperature increases.

Some pool chemicals can also be corrosive. Corrosives are materials that can chew through other materials, breaking them down. They can even damage metal, like your shelf or steel shed wall! What’s worse is if they do start to react and spread, while they destroy materials they can soon make their way onto your skin, eyes, in your respiratory tract or digestive tract damaging and killing what it touches.

Now imagine your children or pets getting hold of these chemicals? The after-effects would be devastating, which is why you need to store them properly!

1. Store chemical containers out of reach of kids and pets and replace lids securely straight after using them so they don’t end up in the wrong hands.

2. Keep pool chemicals in a cool, dry place with a locking feature. Could be a cupboard, shed, cabinet in the garage, or storage box

3. Make sure that the chemicals are never stored in an area with direct sunlight because they can be heat sensitive and will react dangerously

4. Don’t store pool chemicals near other chemicals or flammables, including petrol, detergents, or alcohol

5. Don’t stack different chemicals on top of one another. This is where corrosion could be dangerous and explosions happen.

6. Keep liquid chemicals away from dry chemicals.

7. Storing your chemicals in a well-ventilated area will ensure they do not get moist or overheat

8. Do not store chemicals near the pool heater

9. Keep all chemicals stored in their original containers. Store any liquids below powders when using shelves in your storage. Also, make sure there is no way the water can come into contact with the pool chemicals.

10. Do not reuse containers. Wash out the container when empty and then dispose of it.

Pool Chemicals Storage Solution

You need a reliable and sturdy place to keep pool chemicals as well as a way to lock them away. Below are two great options, which will keep them away from children and pets, out of the sun, and neat so they don’t get damaged. However, our top two recommendations are:

  1. Steel sheds
  2. Garage cabinets and units

Steel Sheds

Pool chemicals - garden shed

Steel sheds are a great and easy way to keep your home a safer place. They come in all shapes and sizes so you can find one to fit your home. Good quality sheds are waterproof and come with hasps on the doors so you can lock them. The best place for your shed would be a shaded area or against a wall. If you live in a fairly hot climate you will need to be careful as the inside temperature of the shed will increase dramatically if it’s exposed to the harsh sun all day.

So make sure you assemble your shed in an ideal spot and make sure you have a padlock for the doors. It’s also recommended you install shelves so you can keep the chemicals well organized and off the floor.

Garage Shelves and Cabinets

Pool chemicals - shelves and cabinets

Inside your garage is a common area for storing chemicals and is usually a bit cooler than outside or a shed. If this is your preferred choice it’s best you have a dedicated area, shelving or cabinet for the pool chemicals because often you will have other chemicals and flammable items in your garage. Best not to get these mixed up! Some options to keep them separate in the garage are:

  • A shelving unit
  • A cabinet
  • Steel storage unit

Last few tips

Pool chemicals - prope ventilation

1.  Make sure your storage solution is well ventilated. Some sheds will either come with or offer window options such as sliding, or louver windows, or even ventilation panels. But If your item doesn’t come with a ventilation system you can easily create some openings in the panels.

2. Always clean and wipe down any residue from your pool chemicals if you spill during use. They can eventually cause damage to anything including your steel shelving or wall panels.

Manufacturer’s warranty may exempt damage from chemicals. Please check warranties carefully before purchase.

    Please remove and change the statement saying using the garage as a storage area for pool chemicals. Pool chemicals, even when in (semi) sealed containers are highly corrosive and off gas. We had storage shelves in our pool house where for years the pool chemicals were kept. All the door hinges quickly became corroded and needed to be replaced. I’d hate to think of the permanent damage done to a cars electrical system. Thank you…
