General Information

Common hazards associated with compressed gases and cryogenic liquids may include:

Storage Requirements

Once a compressed gas cylinder is brought into a research laboratory the user shall follow all of the safe storage requirements listed below:

  • All cylinders larger than lecture bottle size must be secured to a wall or other sturdy device using a strap or chain designed for this purpose.
  • The user shall keep the container valve closed at all times (charged or empty) except when the container is in use.
  • Protective caps must be kept on at all times unless containers are connected to equipment.
  • Containers shall not be placed where they might become part of an electrical circuit.
  • A flame may never be permitted to come into contact with any part of the compressed-gas cylinder.
  • Containers shall not be subject to artificially created low temperatures without approval from the vendor and Brown EHS. Many steels undergo significantly decreased impact resistance and ductility at low temperatures.
  • Compressed Gas Cylinders must be stored and used to avoid incompatible gases from mixing. The best way to ensure that you understand all of the hazards associated with the materials you are using, including compatibility, is to read the Material Safety Data Sheet.
