We have been advised by several of our members that it is now common for chemical suppliers to use the same containers for a variety of reagents. Although the labels are different and contain the relevant chemical name, safety symbols etc., the containers could easily be mixed up when the labels are viewed quickly (see image below).
This increases the potential for chemicals to be added to the wrong dosing tanks, resulting in inadvertent mixing and the possible production of noxious gases. We have been advised of a number of near misses.
Chemicals in question include:
- Sodium hypochlorite
- Polyaluminium chloride
- Hydrochloric acid
- Sulphuric acid
Ensure that your staff are alerted to this issue and are fully trained to take the correct action when storing and handling hazardous chemicals in the plant room.
- Ensure that all chemicals are checked on delivery,
- Ensure the chemical name on the label is correct and placed the containers into the relevant storage area.
- Ensure chemicals are segregated as required and clear identification established.
PWTAG will raise our concern with this practice with suppliers where possible.
Remember: Read The Label
