Here is a risk assessment for working at heights, tailored for Alberta, Canada:

1. Hazard Identification:

• Falls from heights greater than 3 meters (10 feet) 1, 9. Falls from less than 3m where there is increased risk of injury
• Falls into operating machinery, water, hazardous substances, or through openings .
• Unstable or poorly maintained equipment (ladders, scaffolding) .
• Environmental conditions (wind, ice, uneven ground) .
• Falling objects striking workers below.
• Suspension trauma after a fall .

2. Risk Assessment (Likelihood & Severity):

• Assess the likelihood of a fall based on factors like the frequency of work at heights, condition of equipment, weather, and worker training .
• Evaluate the potential severity of a fall, considering the height, landing surface, and potential for striking objects .

3. Control Measures (Hierarchy of Controls):

• Elimination:
  • Design work to eliminate the need to work at heights .
  • Perform tasks from the ground whenever possible .
• Substitution:
  • Use extended tools or equipment to avoid working directly at height .
• Engineering Controls:
  • Install fixed barriers like guardrails and handrails .
  • Use surface opening protection (covers, guardrails) .
  • Employ scaffolding or elevating work platforms 5, 14.
  • Ensure anchor points are stable and appropriate .
• Administrative Controls:
  • Develop a comprehensive fall protection plan specific to the site 1, 16.
  • Implement safe work procedures, including weather monitoring and emergency rescue plans 5, 14.
  • Establish controlled access zones and warning lines 1, 14.
  • Provide thorough training on fall hazards, fall protection equipment, and rescue procedures 3, 10, 12.
  • Inspect all equipment before use and replace defective items 4, 10.
  • Ensure workers are aware of their right to refuse unsafe work .
• Personal Protective Equipment (PPE):
  • Use appropriate fall arrest systems (full body harness, lanyard, lifeline) 5, 12.
  • Provide head protection, safety footwear, and high-visibility clothing .

4. Rescue Plan:

• Develop a written rescue plan that is specific to the worksite and tasks 1, 3.
• Identify trained rescue personnel and their responsibilities .
• Provide rescue equipment and first aid supplies on-site .
• Establish communication protocols and emergency contact information 3, 6.
• Include procedures for rope rescue, ladder rescue, and retrieval lines .
• Ensure the rescue plan addresses suspension trauma and provides for immediate medical care 3, 18.
• The Alberta OHS code states that relying on emergency services is not an appropriate rescue plan .

5. Monitoring and Review:

• Regularly inspect fall protection equipment .
• Continuously review and improve control measures .
• Review the fall protection plan after any changes to the worksite, tasks, or after any near-miss incidents 6, 12.
• Comply with Alberta's Occupational Health and Safety Code, including requirements for fall protection systems and procedures .

6. Additional Considerations for Alberta:

• Alberta OHS Code: Ensure compliance with Part 9 of the Alberta Occupational Health and Safety (OHS) Code regarding fall protection .
• Leading Edge Fall Protection: If using a leading edge fall protection system, follow the specific requirements outlined in Section 158 of the OHS Code .
• Procedures in Place of Fall Protection Equipment: If it is not reasonably practicable to use fall protection equipment, follow the requirements of Section 159 of the OHS Code for using alternative procedures .

By implementing these measures, you can significantly reduce the risk of fall-related injuries and fatalities in the workplace.
