Proper HHW Management Protects
Public Health and the Environment

Many common products are hazardous because they contain chemicals that are toxic, corrosive, flammable or reactive. Improper disposal (pouring down the drain, on the ground, into storm sewers, or in some cases putting them out with the trash) can harm the environment and a pose a threat to human health.  


Pool Chemical Safety


Some of the most hazardous chemicals found in households come from pool maintenance. When getting your pool ready for the swimming season, HHWSTL would like to offer some recommendations.

  1. Check your chemicals to ensure that they were stored properly from last season. Wetted or damp chemicals can cause you some problems. These can be disposed of through the HHW program.
  2. Read all the manufacturer’s instructions before adding chemicals to your pool.
  3. Work in a well ventilated area.
  4. Wear appropriate personal protective equipment like gloves and eye protection.
  5. Never mix chlorine with any other pool chemical, especially other types of chlorine treatments. This can cause explosions and or fires.
