Swimming pool and lawn chemicals can be dangerous if not handled properly. Store the chemicals in their original labeled containers in a cool, dry, well-ventilated place, preferably in a covered area to avoid exposure to stormwater or runoff. Keep different chemicals separated and in undamaged containers to prevent leaks and spills, and out of the reach of children and pets. Always dispose of deteriorating, unwanted or unlabeled pool and lawn chemicals safely, as you would any hazardous waste.
