Reduce electrostatic ignition risk during powder handling
Marc Martens
Combustible powders can create electrostatic charges as they are filled, transferred, mixed or discharged. If that charge accumulates and releases as a spark in the presence of a combustible dust cloud, it can become an ignition source. Controlling electrostatic discharge is therefore an important part of safe powder handling.
Give electrostatic charge a safe path to earth
Conductive packaging can help control electrostatic charge during powder handling. When a conductive drum is properly earthed, accumulated charge can dissipate to ground instead of building up on the container.
This makes conductive drums particularly relevant when combustible or explosion-sensitive powders are filled, emptied, transferred or stored in environments where electrostatic discharge needs to be controlled.
Conductive packaging is one element of a wider explosion-protection strategy. The characteristics of the material, process, equipment and working environment should always be considered as part of a suitable risk assessment.
Combine safe handling with material protection
Controlling electrostatic charge is only part of the packaging challenge. Critical powders may also need protection against moisture, foreign particles, product loss and physical damage throughout storage, handling and transport.
CurTec conductive drums combine conductive performance with the protective properties of high-performance plastic packaging:
- A screw lid with gasket helps protect against moisture ingress and product loss
- Ultra-low moisture vapor transmission rates help protect moisture-sensitive powders
- UN certification supports the transport of hazardous solids
- Lightweight construction supports easier handling compared with metal alternatives
- Multiple capacities help match packaging size to material volumes and handling requirements
- HDPE construction does not rust or corrode
This combination helps maintain both safe handling conditions and product integrity throughout the material journey.
Protect moisture-sensitive combustible powders
Propellant powders illustrate why both challenges can matter at the same time. These materials can present an ignition hazard during handling while also being sensitive to moisture, which can affect their condition and performance.
Traditional packaging solutions may therefore require separate measures for electrostatic control and moisture protection. CurTec conductive drums combine conductive properties, a strong moisture barrier and UN certification in a single packaging solution.
For manufacturers handling propellants, explosives, charge components and other sensitive powders, this can help simplify material handling while supporting both process safety and product protection.
Support demanding powder applications
The need to control electrostatic charge is not limited to one type of material. Conductive packaging can support applications involving combustible or electrostatically sensitive powders across fine chemicals and pharmaceutical manufacturing.
The right solution depends on the properties of the material, the process in which the packaging is used and the controls already in place. CurTec can help assess how packaging fits into your handling, storage, transfer and transport requirements.
Every critical material brings its own handling, protection and logistics challenges. Talk to CurTec about a packaging solution designed around your product, process and supply chain.
