At FAMAT Sampling SA, safety is not an afterthought, it is a design principle.
When developing the 125S sampling valve, our engineering team worked hand in hand with process safety experts and end-users to ensure that every potential risk was assessed and mitigated according to HAZOP (Hazard and Operability Study) methodologies.
A HAZOP study systematically identifies possible deviations in process operation — such as unintended movements, wrong connections, or exposure scenarios, and evaluates their consequences for both the operator and the product.
By integrating this structured approach early in the design phase, we transform risk analysis into concrete mechanical safeguards.
The result: a sampling system that inherently prevents operator exposure and eliminates human-error risks during sampling operations.
Built-in Safety Logic
The FAMAT 125S incorporates a mechanical safety interlock ensuring that every sampling step can only occur under safe conditions:
-
The sampling bottle can only be removed when the piston is fully closed.
-
The piston can only be opened when the sampling bottle is securely attached to the outlet.
This two-step interlock design prevents accidental contact with the process medium and ensures full containment during sampling. The operator cannot bypass the sequence, guaranteeing a safe and compliant operation every time.
From HAZOP to Hardware
Every FAMAT solution is developed through an iterative safety qualification process, combining engineering know-how with user experience feedback.
The 125S embodies this philosophy — a tangible outcome of risk-based design thinking that transforms HAZOP recommendations into mechanical reliability and operator protection.
Beyond compliance, this approach aligns with the highest safety standards in the pharmaceutical, chemical, and fine chemical industries, where containment and reproducibility are essential.
By addressing potential hazards before they ever reach the field, the 125S offers peace of mind to users, ensuring both safety and product integrity, without compromising functionality.
