Pressure systems and equipment

Hazard Knowledge

Examples of pressure systems and equipment are:

  • Boilers and steam heating systems
  • Pressurised process machinery and piping
  • Cylinders
  • Compressed air systems (fixed and portable)
  • Pressure cookers and autoclaves
  • Heat exchangers and refrigeration equipment
  • Valves, steam traps and filters
  • Pipework and hoses
  • Pressure gauges and level indicators
  • Hydraulic equipment
  • Slurry tankers

The potential hazards from pressure are:

  • Impact from the blast of an explosion or release of compressed liquid or gas
  • Impact from parts of equipment that fail or from flying debris
  • Contact with the released liquid or gas - see National Operational Guidance: Hazardous materials, if appropriate
  • Fire resulting from the escape of flammable liquids, gases or mists - see National Operational Guidance: Fires and firefighting

The hazards from pressurised systems increase if the equipment has not been installed or maintained correctly, is not suitable for its use, or has had safety features deactivated or removed.
