3.2 Hazard Identification & Safe Work Practices

Before climbing, ascending in a lift, or working on a scaffold, identify all potential hazards in the work area. Understanding these hazards and applying the correct controls is the foundation of safe work at height.

3.2.1 — Hazards Covered in This Lesson

3.2.2 — Common Hazards Associated with Access Equipment

■

Structural / Collapse Hazards

  • Overloading platforms beyond their rated working load capacity.
  • Inadequate footing or foundation beneath scaffold base plates or outriggers.
  • Missing or improperly installed cross-braces on scaffolding frames.
  • Damaged, corroded, or bent scaffold components used in assembly.
⚡

Electrical Hazards

  • Working near overhead power lines or energized equipment with metal ladders or conductive scaffold tubes.
  • Using aerial lifts on wet surfaces near electrical panels.
⚠
Important

Always identify and maintain minimum approach distances to overhead power lines before positioning any access equipment. Contact the utility or site supervisor to confirm lines are de-energized when in doubt.

⬤

Struck-By and Falling-Object Hazards

  • Tools or materials dropped from elevated platforms onto workers below.
  • Toeboards and debris nets must be in place on all scaffold platforms where work is performed over occupied areas.
☁

Environmental Hazards

  • High winds affecting aerial lift stability and scaffold integrity.
  • Soft or uneven ground causing scaffold or outrigger settlement.
  • Ice, snow, and rain increasing fall risk on platforms and rungs.

3.2.3 — Hierarchy of Fall Protection Controls

The hierarchy of controls must be applied from most preferred to least preferred. Do not rely on a lower-ranked control when a higher-ranked one is reasonably practicable.

1
Elimination

Redesign the task to eliminate the need to work at heights entirely — e.g., assemble components at ground level before lifting into place.

2
Passive Protection

Install guardrails and safety nets that protect all workers automatically, without requiring active participation or equipment to be worn.

3
Fall Restraint

Use a lanyard and anchor point that prevent the worker from reaching the fall hazard zone. No fall occurs — movement is simply restricted.

4
Fall Arrest

Use a full-body harness with shock-absorbing lanyard or self-retracting lifeline to stop a fall once it occurs. Requires a rescue plan.

5
Administrative Controls

Establish safe work procedures, permit-to-work systems, and training programs to reduce exposure to fall hazards through planning and behaviour.

6
PPE — Last Line of Defence

Hard hats, non-slip footwear, and other personal protective equipment. Used when higher controls are not reasonably practicable or as supplemental protection.

3.2.4 — General Safe Work Practices

▶

Before Starting Work

  • Conduct a formal hazard assessment and document it on the appropriate form.
  • Inspect all access equipment and complete a pre-use inspection checklist.
  • Ensure all required permits (e.g., hot work, confined space, aerial lift) are obtained.
  • Brief all workers on the hazards identified and the controls in place.
  • Verify that overhead power lines are de-energized or that appropriate approach limits are in place.
▶

After Work

  • Secure or remove access equipment to prevent unauthorized use.
  • Retract and lock aerial lift controls when the machine is unattended.
  • Document any defects discovered during use and tag defective equipment out of service.
  • Store ladders and scaffold components as per manufacturer recommendations.
