Use Pool Chemicals Carefully

Pool chemicals can cause severe burns, respiratory damage, fire, or death if mishandled. Always read and follow the manufacturer's product label and your local regulations before using any chemical.

• Never mix different pool chemicals. Add products separately.
• Wear gloves and eye protection when measuring or handling chemicals.
• Store products in their original containers, cool and dry, away from children and pets.
• Never add water to a chemical. Follow the product label for any dilution instructions.
• Keep swimmers out until testing confirms that the water is safe.
