Along with the increase in workplace safety and preventive measures, the current pandemic has led to an increase in the risks associated with swimming pool products (chemicals) as more and more people have opted to install a pool or hot tub rather than travel, due to restrictions.

We need to be careful about the safe storage, handling and use of these chemical products as they can cause severe health implications. Various kinds of disinfectants and sanitizers are used to control the growth of bacteria and algae in swimming pool water but can also be used in hot tubs, another popular item being installed. One of the most common disinfectants used to aid in the cleaning of pools and hot tubs is chlorine, purchased as a liquid or dry product.

Why should you be careful?

Many swimming pool products are oxidizers, which mean that they can chemically react with combustible materials, increasing the risk of a fire or explosion. Products such as calcium hypochlorite, commonly known as chlorine powder, are used in water treatment as a bleaching agent to clean and disinfect the water and pool surfaces.

Other pool products are corrosive substances, which can affect metals or cause skin, eye, or respiratory irritation. The extent to which metals and tissues are affected depends on what the product is and its concentration, with some products causing damage immediately as soon as they touch a surface.

Tips for Safe Handling

Do’s

Check the product label before using

Read and follow instructions carefully and ask your pool product supplier for help if needed

Keep containers closed and out of the reach of children and/or pets

Store products separately and use separate and clean measuring cups (plastic or metal) for each substance

Wear personal protective equipment (goggles, gloves, footwear, etc.) as directed in the product instructions

Handle all chemicals in well ventilated areas

Dispose of unwanted or old products safely, such as in hazardous waste drop-off locations

Don’ts

Do not use unlabelled products

No reusing of containers

Do not mix products together and ensure they are stored where they cannot leak or mix with other products

Avoid touching undiluted or concentrated products without proper protective equipment

Do not smoke, eat, or drink when handling products and was hands/clothes thoroughly after handling

Safe Storage Tips

Store products in a cool, dry place away from direct sunlight

Store them in their original containers and keep them out of reach of children/pets

Make sure they are stored in a well ventilated area

Keep oxidizers and acids away from each other

Do not stack containers or store liquids on top of powders/solids

Spills

If you spill large quantities of the product (over 50kg) or if there are signs a chemical reaction is happening, evacuate the area and contact your fire department or local chemical spill emergency response centre immediately (see below for a list of Canadian Provincial emergency telephone numbers).

When cleaning up small spills:

Wear protective gloves (butyl rubber or neoprene), rubber boots, and safety goggles

Keep the area ventilated (especially if indoors)

Place spilled product in a clean, dry plastic bag or container and place in a second bag when finished

Do not put the spill material back in the original container

Dispose of the product according to manufacturer instructions and/or local regulations

Do not generate dust when cleaning up a powder or solid as it can react with skin moisture and cause injury

General First Aid Tips

When providing first aid to an individual exposed to chemicals, you should:

Immediately remove them from the source if it is safe to do so

Quickly remove contaminated clothing, shoes, and leather goods

Immediately flush the contaminated area for at least 15 minutes in warm water

Have someone call for medical help or advice

Make sure you read the product labels and instructions carefully before handling! Speak with your pool product supplier to answer any questions you may have and any specific requirements to the products you are using.
