Safety and risk warning

The risk warnings that follow apply when handling cryogenic media. They do not claim to be complete, and responsibility for safety lies with both the system-designating body and the user. STÖHR ARMATUREN manufacture fittings according to customer specifications in compliance with the given technical standards, and therefore we take no liability for the installation and operation phase beyond. 

Security alert

This website, our product catalogue, the product finder on this website, our sales team and our sales partners abroad will help you select the right valves for your application or project. However, the choice of valve type, its installation, start-up, operation and maintenance are the sole responsibility of the system-designating body and the user. Valve function, type of sealing, material compatibility, operating pressure, operating temperature and the system environment must all be taken into account. 


Risks in dealing with cryogenic gases

The primary risks when dealing with cryogenic gases:

  • Suffocation
  • Frostbite
  • Risk of explosion due to uncontrolled pressure increase during the transition to the gaseous phase (boiling point)
  • Risk of ignition

Possible countermeasures can be:

  • Sufficient ventilation/air exhaust in the workplace
  • Training on the safe handling of cryogenic gases
  • Wearing protective clothing and goggles
  • Cleaning of fittings, gas tanks and pipelines in the media room for the use of combustible gases (oxygen)
  • Constructive safety measures to avoid gas entrapment
  • Development of accident scenarios and rescue plans for emergencies
  • Advance information to emergency services 

Best for Helium - and nothing gets lost.
