At a Rensselaer County home, a lid was left open on a five-gallon pail that contained chlorine tablets allowing moisture to enter the pail. The chlorine tablets reacted with the water, producing chlorine gas and a strong odor in the area. An environmental agency and a hazardous materials team responded to the home and conducted cleanup.
What is chemical wetting?
Addition of a limited volume of water to a chemical.
Why is chemical wetting dangerous?
It can produce an unwanted chemical reaction and release a toxic gas.
Potential sources of water:
- Leaks from roofs, windows, doors, wall and floor joints, water pipes, hoses, sprinkler systems, and drains.
- Moisture from air when the humidity is high.
Ways to prevent chemical contact with water:
||Close containers properly and tightly.|
|Enclose opened or damaged packaging in waterproof containers.|
|Store chemicals off the floor and away from doors and windows.|
|Check for roof leaks, open or broken windows, or leakage from water pipes, hoses or sprinkler systems.|
|Check for faulty or clogged floor drains.|
|Be careful when water is used for cleanup of areas near stored packages.|
