Risk Assessment for Roof Decking

Potential Hazards

1. Tripping Hazards: Shear connectors and other protrusions can create tripping hazards if not properly managed during installation [1].
2. Fall Hazards: Working at heights poses significant risks of falls, especially when working near unprotected edges or openings [2].
3. Falling Objects: Loose materials and tools can fall from heights, posing risks to workers below [2].
4. Structural Instability: Improperly secured decking can lead to structural failures or collapses [3].
5. Weather Conditions: Wind and rain can increase the risk of slips and falls and affect the stability of materials [1].

Risk Assessment

• Likelihood: High, due to the nature of working at heights and handling heavy materials.
• Severity: Severe, as falls and structural failures can result in serious injury or death.

Control Measures

1. Elimination/Substitution: Where possible, use prefabricated components that minimize on-site work at heights.
2. Engineering Controls:
   • Install guardrails and safety nets around the work area to prevent falls [2].
   • Ensure metal decking is immediately secured upon placement to prevent movement [3].
3. Administrative Controls:
   • Implement a controlled decking zone (CDZ) to limit access to areas where decking is being installed [4].
   • Conduct regular safety training and drills for all workers involved in roof decking [5].
4. Personal Protective Equipment (PPE):
   • Use personal fall arrest systems for all workers operating at heights [2].
   • Ensure all workers wear helmets to protect against falling objects.

Monitoring and Review

• Conduct daily safety inspections of the worksite to ensure compliance with safety protocols.
• Review and update risk assessments regularly, especially after any incident or near-miss.
• Maintain a log of all safety training sessions and ensure all workers are up-to-date with their training [5].

Recommendations

• Secure all tools and materials when not in use to prevent them from falling [2].
• Use high-visibility paint or markings to identify hazards such as holes or edges [6].
• Ensure that all decking gaps around columns are filled with appropriate materials to prevent falls [6].

By implementing these measures, the risks associated with roof decking can be significantly reduced, ensuring a safer working environment for all employees involved.
