When should I retire my equipment?

A product must be retired when:

  • It is over 10 years old and made of plastic or textiles
  • It has been subjected to a major fall or load
  • It fails to pass inspection
  • Its reliability is in question
  • Its entire history is not known (e.g. found or second-hand product)
  • When it becomes obsolete due to changes in legislation, standards, technique or incompatibility with other equipment, etc.
