2. Compressed Air Systems

Some smaller vessels have the luxury of a compressed air system onboard. These are often “ off the shelf” units from the local hardware shop.

All compressed air systems have a pressurised bottle which contains the high pressure air. These must be kept in excellent condition. Some housekeeping notes are given below.

Safety points

  • Always wear safety glasses when you are using compressed air.
  • If you use compressed air to dry something, never point the hose directly at the object you are drying.
  • Make sure whatever the compressed air is being used on, is secure.
  • Never use compressed air as an air supply for breathing.
  • Never use air in the vicinity of hot work (welding, gas cutting).
  • Do not use compressed air to clean or dry clothing while you are still wearing it.

Maintenance Points

  • Air storage bottles must be kept in a clean and dry compartment.
  • The paint coating on the bottle must be kept in good condition.
  • Fittings, gauges, valves and relief valves must be kept in good condition with regular maintenance.
  • Hoses used on portable air equipment must be regularly checked for damage and replaced if found.
  • Air Bottles must be rigidly secured to the vessel.
  • Air Bottles have test dates so must be regularly tested.
