Pool Chemical Storage

Only allow those who have been trained in safe chemical storage and handling practices to handle pool chemicals. Give only people trained in chemical handling the responsibilities of ordering, accepting delivery, and stocking of pool chemicals. Maintain good communication among pool chemical handlers. Establish a chain of command among handlers. Document the use of pool chemicals (for example, keep records on the name of chemical added, the reason why it was added, the date and time it was added, and the amount added). Post instructions on safe chemical handling practices in the chemical storage area and pump room. These messages should include: Read product labels or MSDSs. Contact supplier or manufacturer if additional information is needed. Use only pool chemicals in original manufacturer’s labeled containers. Never guess the identity of unlabeled chemicals. If a chemical is in an unlabeled container, do not use it. Read the product name and directions before each use. Do not simply rely on the container’s shape, size, or color to identify its contents. Use appropriate PPE when handling pool chemicals. Check the MSDSs to determine which PPE (for example, safety goggles or gloves) is needed. Keep children and animals away from the area when handling pool chemicals. Do not smoke while handling pool chemicals. Use caution when opening containers to avoid splashing them and generating dust (i.e., minimize the amount of dust generated when handling powdered or granular products). Follow the manufacturer’s instructions on how to use the product. If the instructions call for applying the chemical to the water directly at poolside, do so in an area where the wind or ventilation carry product dust or fumes away from yourself or others. Do not mix individual pool chemicals together or with any other substances. Do not mix different types of chlorine products. Do not mix old and fresh chemicals, even if they are the same product. Dedicate equipment — such as scoops, buckets, crocks, and their lids — to one pool chemical. Do not use this equipment for any other chemical. Label the equipment to indicate which chemical to use with it. Use only dry equipment (for example, scoops) when handling chemicals. Do not pre-dissolve solid pool chemicals or dilute liquid pool chemicals before use. Add individual pool chemicals to water, never the reverse. Close containers properly after each use. Wash hands after working with pool chemicals. Respond to pool chemical spills immediately. Follow the emergency response plan. Never put spilled chemicals back in the original container because they might be contaminated with substances such as dirt or grease. Use separate, dedicated materials to clean up and appropriately dispose of each spilled chemical. Do not pour spilled chemicals down the drain or sewer.

Pool Chemical Storage

Store pool chemicals in compliance with local or state building and fire codes. Store pool chemicals below 95°F/35°C and in conditions recommended by the manufacturer (for example, low humidity and out of direct sunlight). Protect stored pool chemicals from getting wet. Do not store containers of any pool chemical directly on the floor. Store pool chemicals away from doors and windows. Cover opened containers with waterproof material. Check the chemical storage area regularly for any evidence of water entry and fix any identified problems immediately. Potential routes of water entry include roofs, ceilings, windows (particularly if they are open or broken), doors, walls, wall/floor joints, water pipes/hoses, sprinkler systems, and drains (particularly if they are faulty or clogged). Protect individual stored chemicals from mixing together or with other substances. Store each pool chemical separately. Separate all chlorine products from one another (for example, liquid chlorine, calcium hypochlorite, and stabilized chlorine products such as dichlor or trichlor). Store only identical chemicals above or below each other (for example, do not stack incompatible chemicals together). This is particularly important for liquid chemicals, which can leak and then mix with other pool chemicals or substances stored below. Dedicate a storage location to each pool chemical (for example, chlorine and acid). Changing chemical storage locations can lead to chemical-mixing errors. Do not store pool chemicals with incompatible or flammable materials, such as gasoline, oil, grease, fertilizer, herbicides, paint, solvents (for example, turpentine), oily rags, and alcohol. Clean the storage area, pump room, pool deck, chemical safety equipment, and adjacent environmental surfaces only with chemicals that are compatible with pool chemicals. Store chemicals in original, manufacturer’s-labeled containers. Consult with the chemical manufacturer if the container is damaged. Dispose of deteriorating, unwanted, or unlabeled pool chemicals safely. Contact the product’s manufacturer or the local or state hazardous materials group for proper disposal procedures for deteriorating or unwanted pool chemicals. Contact the local or state hazardous materials group for proper disposal procedures for chemicals in unlabeled containers. Protect pool chemicals from heat sources and flames. Do not store possible ignition sources (for example, welding equipment), especially gasoline-, diesel-, or gas-powered equipment (for example, lawn mowers, motors, grills, or portable stoves) in the chemical storage area. Do not smoke in the chemical storage area. Prioritize good housekeeping in the chemical storage area. Do not allow rags, trash, debris, etc. to collect in the area. Limit stored supplies of chemicals by having frequent, regular deliveries. Rotate inventory on a first-in, first-out basis. Store and consume food and beverages away from chemicals.

Construction Include spill containment features, also known as secondary containment, in chemical storage areas to prevent pool chemical leaks or spills from mixing with any other substances. Provide aquatics staff and patrons with easily accessible safety showers, eye wash stations, and other appropriate chemical safety equipment. Install appropriate fire suppression equipment. Consult with your local fire department or code enforcement agency for guidance. Provide adequate lighting for reading labels on containers throughout the chemical storage area and pump room. Air handling (for indoor pools) Follow local building codes and/or American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standards. Separate the air handling systems for the chemical storage area and pump room from the rest of the building. Separate the air handling system for the pool area from the rest of the building. If an older aquatic facility does not have separate air handling systems for the chemical storage area and pump room as well as the pool area, consider installing emergency heating, ventilating, and air conditioning (HVAC) cutoffs in these areas. Ensure that the chemical storage area, pump room, and pool area are well-ventilated. Ventilate the chemical storage area, pump room, and pool area to the outside. Engineering Install an alarm to alert the aquatics staff if the recirculation pump shuts down. Install a device that automatically deactivates the chlorine/pH feed pumps when there is no flow in the recirculation system. Install check valves in chemical feed lines. These valves allow chemicals (liquid or gas) to flow in only one direction and stop suction events from causing an overfeeding of chemicals. Security Secure the chemical storage area and pump room to limit access, especially to children and animals. Provide locking mechanisms for the chemical controller to prevent unauthorized tampering. Material Safety Data Sheets (MSDSs) Ensure availability of and easy access to up-to-date MSDSs near (for example, in the hallway just outside of) the chemical storage area, pump room, pool area, and any other location pool chemicals are stored or used. Ensure availability of and easy access to up-to-date MSDSs at a location other than those listed above in case of chemical spill or accident that would prevent access. Personal protective equipment (PPE) (for example, safety goggles or gloves) Ensure availability of and easy access to PPE near (for example, in the hallway just outside of) the chemical storage area, pump room, pool area, and any other location pool chemicals are stored or used.

Pool Chemical Storage

Having a regular supply of the necessary pool chemicals is essential to keep your swimming pool in good condition. However, to keep the chemicals themselves in good working order, it’s important to store them correctly. This is doubly important because some of these chemicals can be dangerous if not handled and stored safely. Here are some frequently asked questions about where and how to store pool chemicals. Where Should Pool Chemicals Be Stored? The best place to store pool chemicals is in a cool and dry location. Your storage area should also be well-ventilated to prevent the build-up of gasses that may be hazardous. Note that for various reasons, storing pool chemicals in the garage should be avoided. One reason is that over time, gasses such as chlorine will hasten metal rusting. Another is that gasses may build up in a poorly ventilated garage. Can Pool Chemicals Be Stored Outside? If you live in an area where the temperature is moderate, without extremes of heat or cold, then it’s fine to store pool chemicals outside. However, if your climate is subject to extremes, indoor storage may be preferable to prevent chemicals from reacting to heat or freezing. What Kinds of Storage Containers Are Best? Pool chemical storage is safest when the chemicals are stored in the containers in which they were bought. It’s not necessary to transfer chemicals to different containers because the product packaging is designed to provide safe storage. In some cases, it can be dangerous to transfer pool chemicals to new storage containers. This is because some chemicals may react with certain kinds of plastics or metals to form gases or other compounds. Also, note that containers should be properly sealed after every use. Some pool chemicals may react if they come into contact with one another; for example, chlorine and muriatic acid react to form dangerous chlorine gas if they are directly mixed. Solid and liquid chemicals can also react dangerously as dry solid formulations often react strongly with water. The safest option for storing pool chemicals is to put the sealed containers into hard plastic bins with tight-fitting lids. Ideally, use several bins so that you can separate liquids and solids, and so that reactants such as chlorine and muriatic acid can be stored separately. Containers should be stored off the floor, but low to the ground to minimize potential falling damage. To avoid exposure to any gas that builds up, open the containers in a well-ventilated area, preferably outdoors while standing upwind. Are Pool Chemicals Heat-Sensitive? Some chemicals do react with heat, so it’s safest to store pool chemicals away from all heat sources, including sunlight. If pool chemicals are stored outdoors, it should be in a cool and shaded area. It’s also important to note that some pool chemicals are rapid oxidizers, which means that they convert and release oxygen. This reaction speeds up when heat is applied, so these chemicals have the potential to release large amounts of oxygen in the presence of fire. Can Pool Chemicals Freeze? In most cases, pool chemicals are more sensitive to heat than to cold. Some kinds of chemicals can withstand freezing, but it’s generally best to avoid exposing chemicals to extremely cold temperatures, as some may lose strength after cold storage. Check Your Products for More Information While these are some good general rules to follow for safely storing pool chemicals, hazards can vary according to the different products you use. Most pool chemicals come with a Material Data Safety Sheet (MSDS) that provides details of hazards and safe handling practices, so check these to make sure you’re staying safe.
