The act of lifting ladders onto the shoulder is a primary ergonomic risk factor contributing to musculoskeletal disorders among firefighters, particularly affecting the low back and shoulders. This human factors research insight is drawn from a 2022 study published in Academic Publication. Using Cross-sectional survey and observational task analysis with 106 firefighters (questionnaire), 20 firefighters (task analysis), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should prioritize the development of equipment and protocols that mitigate the strain associated with heavy lifting, particularly for tasks like ladder deployment.

Key Findings
- 01Low back pain was the most frequently reported musculoskeletal disorder in the past 12 months.
- 02Lifting ladders onto the shoulder was identified as the most significant ergonomic risk factor compared to hose handling tasks.
Application
Design takeaway
Designers should prioritize the development of equipment and protocols that mitigate the strain associated with heavy lifting, particularly for tasks like ladder deployment.
How to apply
When designing equipment or procedures for physically demanding roles, conduct task analyses to identify specific movements that pose the highest ergonomic risk, and then design solutions to reduce that risk.
Project actions
- 01When researching a physically demanding job, look for studies that identify specific high-risk movements or tasks.
- 02Consider how different body parts are stressed during common occupational activities.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Addresses a real-world occupational health issue.
- +Combines self-reported data with task-specific ergonomic assessment.
Limitations
The study's findings are specific to firefighters and may not directly apply to other professions without similar tasks.
Reliability & validity
The use of established questionnaires (Nordic, QEC) lends some reliability, but the cross-sectional nature limits causal inference, and the sample size for task analysis is small.
Think critically
How might the design of the ladder itself, or the equipment used to transport it, influence the ergonomic risk associated with its deployment?
Design Principles
"Minimize awkward postures and excessive forces during manual handling tasks."
Understanding these specific high-risk tasks allows for targeted interventions in training, equipment design, and work procedures. This proactive approach can reduce the incidence of debilitating injuries, improve firefighter well-being, and maintain operational readiness.
What This Means for Your Design
Lifting heavy ladders onto your shoulder is tough on a firefighter's body, especially their back and shoulders, and designers should think about how to make this easier or safer.
How to use in your project
- 1.Use this study to justify the need for ergonomic improvements in your design project, especially if it involves manual handling or physically demanding tasks.

Paragraph starter
Research indicates that specific occupational tasks, such as the manual lifting of ladders onto the shoulder by firefighters, present significant ergonomic risks, leading to a high prevalence of musculoskeletal disorders, particularly in the low back and shoulders. This underscores the importance of designing equipment and training protocols that mitigate these identified risks to improve worker health and safety.
