Swimming pool chemicals control bacteria and algae and provide a safe and clean pool. In concentrated form these chemicals are potentially dangerous. Swimming pool chemicals are reactive. If accidentally mixed with other chemicals, the mixture can become unstable and produce poisonous fumes or even fire. Pool chemicals do not pose a threat if used and stored correctly.
