the utmost care should be taken when handling and storing them. Failure to do so can cause fires, toxic vapor release and personnel injuries.

It may be a surprise to some that moisture creates large safety hazards with pool chemicals. These chemicals are intended to be mixed into large amounts of water but limited moisture is a different story. Small amounts of moisture can result in an unwanted reaction where there could be a dramatic increase in temperature or a release of toxic gas.

Pool chemicals are typically packaged in plastic bags or drums designed to keep moisture out but this isn’t always successful. The EPA traces the most common causes of moisture entry to roof leaks in a storage facility, a wet floor that the chemicals were not elevated above, leakage from the fire suppression sprinkler system and high-humidity conditions.

In order to prevent these reactions, you must look for ways to keep pool chemicals dry and secure. Proper pool chemical storage can be achieved by fully closing containers, covering exposed packaging and storing chemicals away from doors, vents and windows.

You must ensure that the storage facility has no roof leaks, broken or opened windows or leaks from water pipes, hoses, etc. Pool chemical storage rooms must also have sloped flooring that leads to unblocked floor drains. All chemicals should be lifted from the floor, stored on shelves and covered with waterproof packaging.

Balancing pool chemicals is a science not to be taken lightly. It’s dangerous when pool chemicals come into contact with moisture and is even more dangerous when an unwanted reaction occurs during mixing. The most common pool chemicals are incompatible with each other and mixing them incorrectly can generate a high enough temperature to start a fire. It can also result in the release of highly toxic and corrosive chlorine gas.

Improper chemical mixing incidents can occur when the tools used to handle one chemical are used on another before being cleaned. Incidents can also occur from improperly cleaned chemical containers and spilled substances.

These reactions can also happen when mixing partially decomposed chemicals and new chemicals of the same type. This is why it is so important to keep tabs on the age and quality of pool chemicals.

Proper pool chemical storage arrangements should be made to ensure chemicals aren’t mixed unintentionally. To do so, they must separate incompatible chemicals and avoid keeping containers of liquid above these substances. There should be separate, designated tools for handling each type of chemical and only one chemical should be handled at a time. SDS sheets for chemicals also provide all the correct information on proper chemical storage and handling.

It is always smart make safety a top priority in and around the pool.
