# **Fall Protection on Construction Sites: What Every Worker Must Know**
Falls are the leading cause of construction fatalities in Canada. This guide covers fall protection systems, legal requirements, and practical measures to keep workers safe at height.
**AVANORTH**
AVANORTH Construction
## Falls: The Number One Killer on Construction Sites
According to the Association of Workers' Compensation Boards of Canada, falls from height consistently rank as the leading cause of workplace fatalities in the construction sector. Every year, workers are seriously injured or killed from falls off scaffolding, ladders, roofs, and open floor edges. Most of these incidents are preventable with proper planning, equipment, and training.
At AVANORTH, fall protection is woven into every project plan from day one. We believe that no task is worth a life, and no deadline justifies compromising safety.
## Ontario's Legal Framework
In Ontario, the Occupational Health and Safety Act (OHSA) and Ontario Regulation 213/91 (Construction Projects) set the rules for fall protection. Key requirements include:
- Fall protection is mandatory when a worker is exposed to a fall of 3 metres (about 10 feet) or more.
- A written fall protection plan must be developed before work at height begins.
- Workers must be trained in the specific fall protection methods being used on site.
- Equipment must be inspected before each use and maintained according to manufacturer specifications.
## The Hierarchy of Fall Protection
Not all fall protection methods are equal. The preferred approach follows a hierarchy:
### 1. Elimination
The safest approach is to eliminate the need to work at height entirely. Can the task be completed at ground level? Can prefabrication reduce the time spent at elevation? Always explore elimination first.
### 2. Passive Protection (Guardrails)
Guardrail systems are the next best option because they protect workers without requiring any action on their part. A proper guardrail system includes a top rail at 1,070 mm (42 inches), a mid rail, and a toe board at the base. Guardrails must be capable of withstanding a 900 Newton force applied at the top rail.
### 3. Travel Restraint
Travel restraint systems use a harness and lanyard connected to an anchor point, limiting the worker's movement so they cannot reach the edge where a fall could occur. The worker stays within a safe zone at all times.
### 4. Fall Arrest
Fall arrest is the last resort. It allows a worker to reach the fall edge but stops them after a short distance if they fall. A complete fall arrest system includes a full-body harness, shock-absorbing lanyard or self-retracting lifeline, and a certified anchor point capable of supporting 22.2 kN (5,000 pounds).
## Key Equipment and Proper Use
### Full-Body Harness
The harness distributes fall arrest forces across the thighs, pelvis, chest, and shoulders. It must fit snugly without restricting movement. The dorsal D-ring is the primary attachment point for fall arrest. Side D-rings are for positioning only and should never be used for arrest.
### Lanyards and Lifelines
Shock-absorbing lanyards limit the force transmitted to the worker's body during a fall. They typically extend 1.2 to 1.8 metres and must be attached to the harness D-ring and to an adequate anchor. Self-retracting lifelines (SRLs) allow more freedom of movement and lock instantly when a fall is detected.
### Anchor Points
Every fall protection system is only as strong as its anchor. Anchor points must be engineered and certified to support the required loads. A competent person must identify and approve all anchor points before use.
## Common Fall Hazards on Construction Sites
- **Unprotected floor openings:** Elevator shafts, stairwells, and mechanical openings must be covered or guarded immediately.
- **Roof edges:** Workers on flat or low-slope roofs need guardrails or personal fall arrest when within 2 metres of the edge.
- **Scaffolding:** All scaffold platforms above 3 metres require guardrails. Access ladders must extend 1 metre above the platform.
- **Ladders:** Three-point contact at all times. Never lean beyond the side rails. Secure the top and bottom of the ladder.
- **Excavations:** The edges of deep excavations require barriers and warning signage.
## Training Requirements
Ontario requires that every worker using fall protection equipment receive training specific to the equipment and methods being used. Training must cover:
- How to properly inspect, don, and adjust the equipment
- How the fall protection system works
- The fall protection plan for the specific project
- Rescue procedures if a fall occurs
At AVANORTH, we conduct fall protection training at the start of every project that involves work at height. We verify that each worker's equipment is properly fitted and in serviceable condition before they step onto any elevated surface.
## Rescue Planning
Having fall arrest equipment is not enough. You must also have a rescue plan. A worker who has been arrested mid-fall is hanging in a harness, and suspension trauma can become life-threatening within minutes. The rescue plan must detail how to reach and lower a fallen worker quickly and safely.
Every AVANORTH job site has a documented rescue procedure, trained rescue personnel, and the equipment needed to execute a rescue within minutes of a fall event.
