Closed powder handling, varying degrees of dust elimination
To ensure effective operator protection, it is essential to contain the product on-site, from the first step in the production process until final packaging. The critical point is often the transfer between process units and containers (containers, drums, sacks or FIBCs). OEL/OEB classification (to define workplace limits) is carried out to select a suitable conveyance system. OEL/OEB stands for Operator Exposure Limit/Band.
Once OEL/OEB values have been defined for a new material, or workplace limits have been set for chemical products, the required technical procedure can be defined thereby minimising investment and operating costs.
Hecht Technologie GmbH has developed systems and the corresponding transport containers for all OEL/OEB ranges and workplace limits.

Containment
Containment describes the process of containing a biological agent (medicinal agent, pathogenic factor) or any other substance inside a defined space. The definition "Total Containment is used in the pharmaceutical industry to protect man and the environment and to avoid cross contamination.

Safety by using containment systems for solid material handling
The OEB value (1,2,3,4,5) relates to the toxicity of the substance itself. The aim is to classify systems in order to select production units and processes that are optimally suited to a product.
OEL defines the average concentration load (µg/m³) produced by an active substance measured for 8 hours within the workers' breathing range.
