Performing powder handling operations in a confined environment such as a RABS is essential for enhancing safety during work phases. But how far can this go?
Although a RABS (Restricted Access Barrier System) cannot guarantee the same safety standards as a rigid isolator, the adoption of certain measures can surprisingly bring us closer to these standards.
Our recent installation of a negative pressure control system in a RABS station has yielded very promising results. After analyzing samples collected during the SMEPAC test, we achieved an OEB4 containment level. The structure of the RABS ensures complete visibility inside its two working chambers.
The chamber and post-chamber are separated by an internal door, and the insertion of a drum into the Restricted Access Barrier System is facilitated by an ergonomic linear sliding sled, mounted on a structure designed to support heavy loads. Once the drum is positioned, it’s simply a matter of fitting the wide sleeve which allows it to smoothly slide into the chamber through the dedicated canister, thus enabling easy material transfer.

From within the RABS, it is possible to perform dispensing operations in conditions that offer greater protection for both operators and the product itself, minimizing the risk of environmental contamination. The post-chamber allows for the safe transfer of samples outside, eliminating operator exposure to the product.
