Packaging/Storage
Product is supplied in 45 kg plastic pails. HTHTM Briquettes can be stored up to 2 years after its manufacturing
date under normal temperature and humidity conditions.
However, there is a potential for slow release of gases, primarily chlorine gas in very limited quantities due to
the degradation of the material over the time.
The product must be kept protected from light. Drums must be stored upright in a well ventilated area with
containment facilities. Drums must be handled carefully when lifted and moved.
