Siding a 6-story building presents significant fall hazards that require careful risk assessment and mitigation. Here's a breakdown of potential hazards and control measures:

Hazards:

• Falls from Height: This is the primary hazard when working on a 6-story building. Employees can fall from the working surface to lower levels [1].
• Falling Objects: Tools, equipment, or siding materials can fall and strike workers below [1].
• Scaffold Instability: Improperly erected or maintained scaffolds can collapse [2].
• Electrical Hazards: Contact with overhead power lines is a risk if working near them.
• Weather Conditions: Wind, rain, or ice can create slippery or unstable working conditions.

Risk Assessment:

• Likelihood: High, given the height and constant exposure to fall hazards.
• Severity: Critical, as falls from this height can result in serious injury or death.

Control Measures:

1. Fall Protection Systems:

   • Guardrail Systems: Install guardrails on all open sides and edges of scaffolds or working platforms [1]. Ensure they meet height and strength requirements [3].
   • Personal Fall Arrest Systems (PFAS): Provide and require the use of PFAS, including harnesses, lanyards, and anchor points [1]. Ensure proper training on their use and inspection [4].
   • Safety Net Systems: Install safety nets below the work area to catch falling workers or objects [1].

2. Scaffolding Safety:

   • Competent Person: A competent person must inspect the scaffold before each work shift to ensure it is safe to use [2].
   • Proper Erection: Scaffolds must be erected by trained and experienced personnel following manufacturer's instructions and relevant safety standards [4].
   • Load Capacity: Ensure the scaffold can support the intended load of workers, materials, and equipment 5, 10.
   • Bracing: Properly brace and tie the scaffold to the building to prevent swaying or collapse [2].
   • Planking: Use scaffold planks that are the correct size and grade, and ensure they are properly secured 6, 18.

3. Falling Object Protection:

   • Toeboards: Install toeboards on scaffolds to prevent tools and materials from falling 8, 10.
   • Debris Nets: Use debris nets to catch falling objects and protect workers below.
   • Tool Lanyards: Require workers to use tool lanyards to prevent tools from falling.
   • Hard Hats: Enforce the use of hard hats at all times on the job site.

4. Electrical Safety:

   • Hazard Assessment: Identify and assess the risk of contact with overhead power lines.
   • Safe Distance: Maintain a safe distance from power lines or de-energize them if possible.
   • Insulated Tools: Use insulated tools and equipment when working near electrical hazards.

5. Weather Considerations:

   • Monitor Conditions: Continuously monitor weather conditions and suspend work if necessary.
   • Slip Resistance: Use slip-resistant footwear and ensure working surfaces are free of ice, snow, or water.

Monitoring and Review:

• Regularly inspect fall protection equipment and scaffolds.
• Conduct safety meetings to discuss hazards and safe work practices.
• Review the risk assessment and safety plan periodically and update as needed.

Specific Recommendations:

• Develop a comprehensive fall protection plan that addresses all potential fall hazards.
• Provide specific training to all employees on fall protection, scaffold safety, and other relevant topics [4].
• Use a combination of fall protection measures, such as guardrails and personal fall arrest systems, for maximum safety.
• Ensure that all workers are aware of the hazards and control measures in place.
