HECHT Containment Systems
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. It defines the average concentration load (µg/m³) produced by an active substance measured for 8 hours within the workers' breathing range.
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.
