Preventing falls from roofs: a critical review.

Area of Science:

• Occupational Safety and Health
• Biomechanics
• Human Factors Engineering

Background:

• Work-related falls from roofs are a significant safety concern in the construction industry.
• Falls are often initiated by loss-of-balance incidents, influenced by various factors.

Purpose of the Study:

• To synthesize existing knowledge on factors impacting balance control during roofing work.
• To identify environmental, task-related, and personal factors contributing to falls from roofs.

Main Methods:

• Extensive literature review across multiple scientific fields.
• Analysis of factors affecting balance control in the context of roofing tasks.

Main Results:

• Identified numerous factors degrading balance control, including visual-environmental challenges (e.g., elevation exposure, poor visual cues), surface conditions (confined, inclined, changing), physical demands (load handling, exertion, fatigue), cognitive load (task complexity), and individual differences (experience, training, PPE).
• Current fall prevention measures (e.g., fall protection systems, safety monitoring) are often impractical, with regulations allowing less effective alternatives.

Conclusions:

• Future research must integrate the effects of environmental, task-related, and personal factors on worker balance.
• Improvements in the work environment, materials, methods, and procedures are needed to enhance balance control and reduce fall incidents in roofing operations.
