What risks does improper storage of pool treatment chemicals pose?

Ensuring excellent water quality in swimming pools and spa centres intended for public use is one of the most important priorities owners should focus on.

In compliance with the regulatory requirements, today this can be achieved through innovative methods of control, such as the HealthySwim technology, for instance. Yet, the use of various chemicals continues to play an important role in water treatment in public swimming pools.

In view of this, in the following article we would like to draw your attention to the storage of pool treatment chemicals. We will focus specifically on the risks that improper storage of such chemicals may pose.

How should we store pool treatment chemicals?

Pool chemicals should always be stored in a clean, cool, dry and well-ventilated space. Pool owners, who use chemicals for maintenance, should have such storage space.

It is important that the storage area is large enough to ensure proper arrangement of the chemicals according to their type and their physical form (solid, liquid, powder, etc.). In other words, it should provide enough space for different types chemicals to be physically separated from each other.

Low temperature

Pool chemicals typically come with a long shelf life, as well as specific instructions regarding the temperatures they should be stored at. These temperatures are usually comparatively lower, so your storage area should meet those conditions.

Away from moisture

The presence of moisture in the areas used for storage of chemicals is detrimental. Moisture may affect the properties of the chemicals, as well as their labels.

Good ventilation

Some chemicals, such as oxidizers for example, release toxic fumes over a prolonged period of time. In order to minimize the negative effects of fumes release, the areas, used for ling-term storage of such chemicals should be equipped with good ventilation system.

Physical separation of individual groups of chemicals

This requirement relates to liquid chemicals being separated from dry ones, for example. Liquid chemicals should not be placed on top of dry ones and vice versa to minimize the risk of possible leak or spill and chemical interaction.

Away from heat and/or ignition sources

Chemicals used for water treatment in public swimming pools, as well as other water facilities within the complex, should be stored away from sources of heat and/or ignition sources. Containers with chemicals should be kept away from pool heaters and/or hot tubs. Heat sources have the ability to decompose chemicals.

What are the risks of improper chemical storage or treatment?

Failure to comply with the above-mentioned rules for storage of hazardous chemicals for treatment of swimming pools, hot tubas and other water attractions poses significant risks. We will briefly summarize the main ones below:

Danger of spills

Even a small and seemingly harmless spill of one and/or several chemicals may trigger a chemical reaction – a fire and/or release of toxic fumes harmful to those working with the chemicals. Different types of oxidizers should not be kept near each other.

Interaction between the chemicals

Chemicals have the ability to interact with each other. For example, calcium hypochlorite and dichloroisocyanuric acid can react with each other, causing a violent chemical reaction and release of fumes containing toxins which are dangerous if inhaled.

Risk of fires

Some chemicals are highly flammable. If placed near heat sources, they can ignite and lead to fires, causing severe material damage and/or injuries to the people handling them. Ideally, all chemical substances should be kept locked at all times and only authorized pool personnel should be granted access to them.

Risks of improper handling of chemicals

When treating pools, hot tubs and other water facilities, all safety precautions should be observed. All personnel handling chemicals should use personal protective equipment, such as safety goggles, protective gloves, etc.

Never mix different types of chemicals, as this may result in a dangerous chemical reaction. Measuring equipment used for the chemicals should be dry and clean.

Chemicals of different batches should not be mixed. Older stocks of chemicals may have lost some of their properties and may affect the properties of new ones, when mixed with them.

All chemicals should be stored in their original containers and packaging, sealed with their lids. This ensures that they will not be contaminated in any way. The operator responsible for maintaining pool cleanliness should always make sure that they are tightly closed.

The instructions on the labels that come with the containers and packaging of the chemicals should be strictly observed. Labels should be kept intact, as they contain important information about the chemical composition, properties and usage of the chemicals.
