Room air monitoring and safety status
In most of the nitrogen storage depots a filling site for dewars must be provided. Liquid nitrogen in small quantities can be taken here to supply the laboratory section as well as small storage containers. This distributor point is associated with the largest incalculability. Accidents can arise mostly here. Therefore the assigned operating personnel must legitimate itself with an access control system for enabling the nitrogen feeding for a limited time. In order to ensure that the filling process is supervised for the whole time, presence detectors are installed. If the operator leaves the room or becomes unconscious, the nitrogen feeding is interrupted.
The nitrogen traffic light gives information about the safety status of nitrogen storage depot:
Each nitrogen storage depot is unique. The first stage is the risk analysis in accordance to the "Betriebssicherheitsverordnung" made by the manager. The procedural and technical safety requirements are integrated in an individual project. This is the basis for the safe layout and professional installation of the facility.
