Personal and Collective Work at Height Hierarchy Measures – what is the difference?

The Health and Safety Executive state that collective measures should always take priority over personal PPE measures but, what is the difference? In this blog we look at the difference between control measures and, the equipment and safety systems associated.

Collective Measures

Collective measures should always protect more than one person at any one time and, require no intervention by the user to work effectively.

  • Guardrail Systems
  • Leading Edge Barrier
  • Vehicle Safety Fall Protection


Personal Measures

Personal measures rely upon PPE (Personal Protective Equipment) and, only protect the user. Most commonly personal measures are active, meaning that the user is required to utilise something for it to work effectively – such as attaching PPE to a fall prevention system.

  • Safety Line, Cables and Track Systems
  • Abseiling and Rope Access Systems
  • Eyebolts and Roof Anchor Systems
  • Mobile Man Anchors
  • Vehicle Safety Fall Protection
  • Personal Protective Equipment



Do you know how to select the correct PPE? It is a crucial competency for any operative who carries out work at height within their role. As a legal requirement, it is an employer’s responsibility to ensure that any employees or contractors who work at height are certified with the correct training.
