It’s a success: City of Perth’s ergonomic assessment

Risk Matters - Summer 2022 / 23

Before and After

Spot the difference! City of Perth get proactive to avoid musculoskeletal injuries

The City of Perth engaged the LGIS injury prevention team to evaluate workstations of a group of employees at their depot to make sure they were comfortable, safe and less likely to injure themselves. 

LGIS Injury Prevention Consultant, Darryl Griffiths, visited the depot to observe employees’ current work methods, equipment layout and complete an ergonomic evaluation.
The identified hazards during this assessment were quite specific, however common ergonomic issues our injury prevention consultants encounter include awkward sitting postures, incorrect backrest height and angle, poor monitor heights, angles and distances, and overreaching for the keyboard or mouse. 

Ergonomic assessments are available to all LGIS members; it’s included as another benefit of membership. 

Why injury prevention?

Injury prevention is a key component of any health and wellbeing structure at a workplace. The Scheme injury prevention program is included as part of membership and supports WA local governments in reducing injuries in the workplace. 

Our team is focused on proactive and strategic services to assist members with reducing the risk of manual task injuries in the workplace. LGIS services are interactive and engaging, and focus on outcome based learnings to empower workers to apply the principles on an ongoing basis in their roles.

How to safely work in heat?

The Work, Health and Safety Act WA (2020) requires local governments (PCBUs) to ensure health and safety, so far as is reasonably practicable, by eliminating hazards and risks.

What is LGIS’ ergonomic process?

An ergonomic assessment is designed to assess a worker’s environment to ensure they are correctly set up, thereby minimising the risk of injuries, aches or pain, and maximising productivity. Below is a list of the range of ergonomic solutions available through LGIS.

1. Basic ergonomic assessment (15 minutes)

Designed for workers with no pre-existing pain or discomfort.

2. Comprehensive ergonomic assessment (30 minutes)

Suitable for workers currently experiencing pain or discomfort.

3. Telehealth ergonomic assessment (20 minutes)

Using Zoom as a platform, our injury prevention team can help workers setup and adjust their workstation via a telehealth assessment. This can be provided for both office and home workstations.

4. Vehicle/plant ergonomic assessment (30 minutes)

Spending long hours driving in a static posture can lead to pain and discomfort. This assessment is designed to ensure safe and appropriate sitting postures when driving or operating.

5. Home office workstation assessment (30 minutes)

Designed for computer- based workers, who work from home, to ensure their workstation and environment is set up in line with ergonomic principles.

Following the assessment, an individual report is completed, which includes recommendations for changes, and outlines
any new equipment that may be required.

In this instance, a purchasing officer within the City of Perth’s fleet and depot services department was evaluated due to concerns regarding his workstation layout and discomfort he was experiencing as a result.

Take a look at LGIS’ key findings, hazards and improvements: 

Key findings

We identified some hazards which contributed to fatigue and employee discomfort.

  • The employee undertook computer based tasks on a frequent basis. 
  • During the day, he used three monitors – two monitors were located on the workstation skewed to the right, and a third monitor (providing front gate surveillance for the depot) located on the upper right side wall (approximately 180 cm above the floor). See before image.
  • There was a large hutch at the rear of the workstation which reduced the available workspace.
  • The worker used a very small wireless mouse. 
  • He reported significant neck discomfort.

Identified hazards:

  • Awkward neck posture to view the front gate surveillance monitor (extension and rotation)
  • Constrained workspace due to the dual monitor stand location and rear-hutch shelving.
  • Awkward wrist posture when using the mouse. 


  • The rear vertical hutch/cabinet was modified by removing multiple shelves. This allowed the dual monitor arm to be moved further back on the workstation.
  • The monitor arm was located centrally in line with the employee.
  • The front gate surveillance monitor was relocated from the upper right wall to down to the desk level on the left of the employee.
  • A larger mouse was provided. (see after image)

How it benefited the City of Perth employee

  • Improved workflow with being able to view all computer monitors easily.
  • Improved neck posture when viewing monitors.
  • Increased workspace after moving the monitor arm back and modifying the vertical hutch.
  • Improved right wrist posture when using the mouse.
  • Improved morale with rapid improvements being made.
