Handling and Storage of Chemicals.
The chemicals needed for your spa to help make it clean, disinfected and more attractive to use are potentially dangerous and may present some hazards if not used properly. Carefully follow the manufacturer's instructions for the use and storage of chemicals. In general, here are some tips for chemical use and storage:
Before using chemicals, read the labels and directions carefully. Follow label use instructions. Hand must be clean and dry... always wash hands after handling chemicals. Use plastic, glass, china or enamelware utensils and pails only and be sure they are clean and dry before using...Never use metallic utensils. Add chemicals to water. Never add water to chemicals. Always add the chemicals directly to the pool water, either in a suitable feeder, distributed across the surface of the pool, or diluted and poured into the water. Follow label use instructions. When preparing water solutions for feeder application (e.g., disinfectant or soda ash), pour the chemical slowly into the appropriate amount of water, stirring constantly to provide mixing and dilutions. Never add chemicals to the pool water while swimmers are using the pool. Keep all chemicals out of the reach of children. Never mix chemicals together. Use a clean scoop for each chemical, and never combine material from "old" and "new" containers. Never reuse old chemical containers. Wash out empty disinfectant containers before disposing, to eliminate danger of fire, explosion or poisoning. Carefully clean up any spilled chemicals with large amounts of water, to dilute and wash away the chemicals. Check with local authorities before sending disinfectants and pH adjustment chemicals to the sewer as waste. Do not inhale dust or fumes from any pool chemicals. If necessary use protective devices for breathing, handling and eye protection. Promptly wash off any residues which get on your skin. Test the water in your pool with a reliable test kit on a schedule recommended by your pool professional. As a rule, the more people who use your pool, the more frequently you should test the water. Add the necessary chemicals according to the test results and the manufacturer's instructions. Chemicals for test kits should be replaced each year. If you have any questions regarding safe handling, storage or use of pool chemicals, contact the manufacturer.
NOTE: Pre mix chemical to be added into a large plastic bucket of water and then add to spa as a liquid, adding granular products may damage spa.
NEVER MIX TWO OR MORE CHEMICAL TOGETHER AT ONCE
Chemical reagents for test kits should be replaced each year. Keep the original lids on all chemical containers and make sure the lids are closed tightly when not in use. Do not stack different chemicals on top of one another. Keep liquid chemicals away from dry chemicals. Keep apart chemicals which are different forms of oxidizing compounds. Physically separate all different forms of chemicals. Store your pool chemicals in a clean, cool, dry, well-ventilated area preferably off the floor, to prevent contamination from other materials. Especially, do not store chemicals near the pool heater. Keep them away from chemicals and equipment used for garden and lawn maintenance. Keep acids away from other chemicals. Keep all chemicals out of the reach of children. Do not store your pool chemicals where other flammable items may mix with them. For example, a mixture of pool chemicals and fertilizer can cause a fire or explosion. Wash your hands thoroughly after using.
