Height Safety

Working at height is often misunderstood. When most people think of working at height, they are immediately drawn to visions of someone working on a high-rise building or a tower, and perhaps how dangerous this can be. Whilst working at these heights clearly poses significant personal risk, these workers will often take a lot of care and attention to their personal wellbeing when they are exposed to these conditions.

The reality is, working at height is a lot more prevalent across many industries than just those high-profile applications. Testimony to this is that a significant number of the injuries that occur from falls from heights in the workplace occur from less than 3m above the ground. This is why the definition of “working at height” is simplified to where a worker has:

…a risk of a fall from one level to another that is reasonably likely to cause injury to the worker or another person.

This definition highlights that a potential fall could occur from one elevated level to another level, from an elevated level to the ground, or even from the ground into a below-ground level via an opening. People often forget that fall risks also exist at ground-level, not just from above it. Falls through a penetration in a building into a pit or sewer or other form of below-ground cavity also represents a significant risk of personal injury and is included in the broader definition of “falls from height”.

Despite significant Regulatory support, resources and education, falls from height are still a major contributor to deaths and serious injury in Australian workplaces.

Since 2018, Safe Work Australia has consistently reported Falls from Height and Being Hit by Falling Objects as the second and fourth leading mechanisms of workplace fatalities. The data provides a clear and sobering picture of the persistent risks associated with working at height and the management of dropped object hazards.

 

Between 2018 and 2024, Safe Work Australia recorded:

  • 160 fatalities from falls from height
  • 123 fatalities from falling objects

This represents 283 worker deaths in just seven years — an average of 47.2 fatalities every year linked directly to height-related hazards.

 

Breaking that down further:

  • Falls from height: average 26.6 deaths per year
  • Dropped objects: average 20.5 deaths per year

 

Put simply, on average:

  • A worker dies from a fall from height approximately every 13 days.
  • A worker is killed by a falling object approximately every 18 days.
  • Combined, a height-related fatality occurs roughly every 7–8 days in Australia.

Ways to minimise the risk of falls

The most effective way to protect workers from the risk of falling is to eliminate the need to work at heights.

There are some general principles that can be applied in the “elimination” process:

Avoid the risk by removing the need to work at height where reasonably practicable.

Prevent falls – where it is not reasonably practicable to avoid work at height, assess the risks and take measures to prevent, people or objects falling.

Minimise the consequences of a fall – where the risk of people or objects falling still remains, take steps to minimise the distance and consequences of such falls.

When the risk of a fall cannot be eliminated completely (by removing the need to work at height), passive and active control measures can be used (from most preferred to least preferred):

These approaches are commonly referred to as the Fall Protection Hierarchy of Controls.

ABCDEs of fall protection.

Regardless of the method of harness use, every system involving fall protection should incorporate at least the 5 basic elements of safety when working in a harness:

Harness Based Work at Height

Harness-based work at height refers to any access undertaken where workers use a webbing full body harness to secure themselves whilst attached to a rope, lanyard, self-retracting lifeline or other safety device and place themselves in a position to work, that if they were not wearing such equipment, they could potentially expose themselves to a serious fall.
