Pool chemicals are hazardous substances used to maintain health and safety of pools, spas and other aquatic areas. But in a retail setting – where you can have large amounts of these goods – what are the considerations you need to make to ensure these chemicals don’t harm staff, customers, property or the environment? In this post, we dive (sorry, but it had to be done!) into the requirements for retail outlets that stock pool chemicals.
As Australians, most of us are familiar with the pungent smell of chlorine in a spa or swimming pool — but what hazards are these chemicals actually posing to the people that are working with them?
Pool chemicals are strong substances that may have a range of properties. These are specific to the chemical product but may include corrosive, oxidising, water-reactive or combustible properties. This means that chemicals may corrode metal or living tissue (including human skin and eyes), react with other chemicals or increase a fire hazard.
Due to the hazardous nature of pool chemicals, these products must be stored and managed in a way that prevents harm, such as health issues, environmental damage or corrosion of property.
There are many hazardous substances required for pool maintenance, but these must be stored and handled in a way that reduces harm.
The first steps in determining how to handle and store your pool chemicals is understanding what substances you’re storing.
Many pool and spa chemicals are deemed ‘hazardous’ in the Globally Harmonized System of Classification and Labelling of Chemicals (otherwise known as the GHS).
The GHS is an internationally recognised system that allows the accurate communication of information about hazardous chemicals through labelling and safety data sheets. Knowing the physical and health hazards of the pool chemical is vital for maintaining the health and safety of any workplace operations.
Safety data sheets of hazardous chemical products outline the physical and health hazards associated with that substance. There are many sections that offer vital information about the substance including:
Understanding this information will provide the foundation upon which your risk management process is built. Whether you're dealing with the dangers of pool chemicals (or other hazardous chemicals or dangerous goods) in your organisation, a risk management approach is crucial for health and safety.
REMEMBER: Learn more about safety data sheets, including how to read, store and maintain them, in our helpful blog post.
In Australia, commonly used pool and spa chemicals include disinfectants, pH balancers, algaecides, and other specialised treatments. Here’s a rundown of some of the most widely used types:
Chlorine:
pH Balancers:
The Australian Standards are highly detailed documents which are considered best practice for dangerous goods and hazardous substances.
There are various Australian Standards that may apply to pool chemicals, including:
and, when using mixed classes of chemicals, such as those with corrosive properties and oxidising properties:
You can use these Standards in your workplace for guidance on how to handle and store your substances, with relation to ventilation, handling practices, storage equipment, spill control, first aid and emergency procedures.
REMEMBER: While the Standards are best practice, retailers must always abide by the Work Health and Safety laws or Dangerous Goods laws that apply to their region. Learn more in the blog Storing Dangerous Goods in a Retail Setting.
Just like any type of hazardous substance or dangerous goods, there are basic steps required to control risks. While an onsite risk assessment is important for understanding the complete picture in regard to chemical safety, there are some key considerations to make when selling pool chemicals.
Many substances should not be mixed or stored near each other due to the potential for harm. A liquid pool compatibility chart is an important resource that can prohibit incompatible substances from being mixed in the spa or pool.
Segregation of goods is also vital for the safety of the retail outlet and surrounding community, as incompatible substances can become unstable or react. For example hydrochloric acid is not compatible with hypochlorite solutions.
The Australian Standard for mixed goods AS 3833 explains that pool chemicals must be segregated from incompatible substances and those that might react dangerously. Segregation includes:
Always remember that some chemicals can still be incompatible or react dangerously within their own class, so always determine the incompatibilities or reactions of your individual pool products.
IMPORTANT: Read more about segregation in a retail business in the blog Retail Stores: Segregation Requirements When Carrying Mixed Classes of Dangerous Goods.
When storing hazardous chemicals, a register is a must. This register is a list of all hazardous chemicals at your store, which must be always kept up to date. Unlike the manifest, which is only for businesses with chemicals above manifest quantities, the hazardous chemical register is required when carrying any volume of hazardous chemicals.
Check with your local regulator to determine if you also require a hazardous chemical manifest for your business. The manifest will be required if the type and quantity of chemical exceeds a certain amount. The manifest must be prepared in accordance with regulations and may have to be submitted to your local fire service.
The manifest is for emergency services who may attend your site and must be stored in an Emergency Information Box at a specific location on your property. You may liase with fire services when determining the best location.
While every precaution should be made to ensure that there are no spills of pool chemicals, accidents can happen. However, it’s your duty to make sure that these minor chemical spills don’t become a major problem.
Spill containment and clean up should be conducted by trained personnel who are wearing the appropriate PPE (see your safety data sheet) for the spilled substance. Areas should be cordoned off so that no customers come into contact with the spill, and care should be taken to ensure that adequate ventilation is considered during the clean-up process. Use the appropriate spill kit that is both compatible with your substance and suitable for the quantity spilled.
The proper waste disposal procedures must also followed to ensure that no hazardous chemicals are thrown out with the regular rubbish – potentially harming people or the environment.
Staff should have easy access to safety data sheets at all times, so they can better handle and store these pool chemicals in the safest possible manner. If there is an incident, such as a fire or large spill, emergency services will also need access to these safety data sheets so they can accurately assess the situation and provide a suitable emergency solution. We recommend storing safety data sheets in an SDS folder and document holder that’s located close to the chemicals that you’re storing. The safety data sheet folder will keep the SDS safe and accessible, with a waterproof SDS holder being able to be attached to walls or storage.
When managing the risks of any type of hazardous chemical, airborne contaminants are a key concern. Chemical exposure doesn’t only happen if substances are spilled onto the skin, harm can occur when the vapours are breathed in by workers or customers.
Keeping your store clean, tidy, free of spills and well ventilated is part of maintaining a healthy, safe workplace.
Working in retail isn’t just about reducing the dangers within your store – it’s also about reducing risk in all aspects of your operations.
Spills and other hazardous incidents can occur when chemicals are being delivered or transported around a business. Care must be taken to develop procedures that reduce the likelihood of a pool chemical spilling or coming into contact with incompatible substances, ignition sources or other prohibited items.
Guided by your safety data sheet, retailers must adhere to the storage practices required for individual chemical products. Many substances may react or become unstable if they aren’t stored in the correct conditions.
