A. WHEN FALL PROTECTION IS REQUIRED
OHS regulations specify when fall protection to workers working at heights is required based on:
- How high up they are (typically 3 metres or higher);
- The surface or platform they work on (e.g., vehicles, scaffolds, sloped rooves); and
- What they’re at risk of falling through, on or into (e.g., machinery, hard surfaces, water).
But while the approach is the same, specific criteria vary by location.
- On unguarded structure or vehicle > 3 m or more above nearest safe level
- On ladder > 3 m or more above nearest permanent safe level where worker can’t use at least one hand to hold ladder
- at a height of less than 3 m if surface on which person might fall presents greater risk of injury than a solid, flat surface (COHS Regs, Sec. 12.07(1))
- A vertical distance of 3 m or more
- A vertical distance of less than 3 metres if there is an unusual possibility of injury, i.e., if the injury may be worse than an injury from landing on a solid, flat surface
- Into or onto a hazardous substance or object
- Through an opening in a work surface, or
- At a permanent work area, a vertical distance of more than 1.2 metres and less than 3 metres (OHS Code, Sec. 139(1))
- Where they risk falling 3 m or more
- Where they risk falling < 3 m but risk of injury is greater than risk of injury from impact on flat surface (OHS Reg., Sec. 11.2(1))
Where they risk falling:
- 3 m or more
- < 3 m but risk of injury is greater due to surface or item they may land on
- Into operating machines or moving parts
- Into water or other liquids
- Into or onto a hazardous substance or object
- Thru an opening on a work surface
- >1.2 m from area used as path for wheelbarrows or similar equipment
(Workplace Safety & Health Regs., Sec. 14.1(1))
Where they risk falling from:
From unguarded work area that’s:
i. 3 m or more above water or nearest permanent safe level
ii. Above surface or thing that may cause injury hurt on contact
iii. Above any open top tank, bin, hopper pit or vat
- From a work area platform 3 m or more above permanent safe level and from which they may fall if the area platform tips or fails
- Communication or power transmission tower or similar structure 3 m or more-high
- From In a work area that a govt OHS officer determines official says requires a fall-arrest use of a fall protection system
- From a communication or power transmission tower or similar structure 3 m or more high
(OHS General Regs., Secs. 49(1) + (2))
- 3 m or more above nearest safe surface or water
- Above surface or thing that could cause injury were worker to fall on it
- Above open tank, pit or vat containing hazardous material
- 3 m or more above nearest safe surface or water
- Less than 3 m when the work area is above one of the following:
i. a surface or thing that could cause injury to the person on contact that’s worse than an injury from landing on a solid, flat surface
ii. exposed hazardous material, such as in an open tank, pit or vat - Fall protection required only if reasonably practicable if work if work must be performed on or from a vehicle, rail car or other mobile equipment

ii. where the surface is slippery (WSC Regs., Sec. 1.37)
B. MAXIMUM FALL ARREST FREE FALL DISTANCES & ARRESTING FORCES
Fall arrest systems don’t prevent falls but stop them before a worker plunges too far. But the action of arresting a fall can put a lot of stress on the body creating physical shock that can injure or even kill the worker. Accordingly, fall arrest systems are subject to stricter design, use and installation requirements including with regard to:
- How far they can let a worker fall before arresting it; and
- How much force they can exert on the worker’s body in arresting the fall.
Jurisdiction | Maximum Free Fall Distance (assuming no shock absorber used) | Maximum Arresting Force (in kiloNewtons (kN) |
---|---|---|
Federal | As specified by CSA Z259.2.4-2.5 | As specified by CSA Z259.2.4-2.5 |
Alberta | 1.2 metres | 6kN (8 kN if worker is using E6 shock absorber in accordance with manufacturer’s instructions) |
British Columbia | 1.2 metres | As specified by manufacturer |
Manitoba | 1.2 metres | 8 kN |
New Brunswick | 1.2 metres | 8 kN |
Newfoundland & Labrador | 1.22 metres | 1.22 metres |
Nova Scotia | 1.22 metres | 8 kN |
Ontario | GENERAL INDUSTRY 1.5 metres CONSTRUCTION |
GENERAL INDUSTRY 8 kN CONSTRUCTION |
Prince Edward Island | 1.22 metres | 4 kN (where system isn’t equipped with a shock absorber) |
Québec | GENERAL INDUSTRY Not specified CONSTRUCTION |
GENERAL INDUSTRY Not specified CONSTRUCTION |
Saskatchewan | *if no shock absorber: 1.2 metres *if shock absorber is used: 2 metres or distance specified by manufacturer |
8 kN |
Northwest Territories & Nunavut | *if no shock absorber: 1.2 metres *if shock absorber is used: 2 metres or distance specified by manufacturer |
8 kN |
Yukon | 1.2 metres | As specified in CSA standard applicable to equipment used |
C. WHERE & WHEN A FALL PROTECTION PROGRAM IS REQUIRED
All but 3 jurisdictions—Manitoba, Ontario and Quebec—require employers to codify their fall protection measures into a written document called a fall protection program or plan. Here’s a look at where fall protection programs are required and under which circumstances.
Jurisdiction | Fall Protection Program Mandatory When: |
---|---|
Federal | Workers are at risk of falling from:
|
Alberta | Workers are at risk of falling 3 or more metres AND there are no guardrails |
British Columbia | Workers are at* Work is done at location where there’s a risk of falling 7.5 metres or more metres and AND workers aren’t protected by permanent guardrails OR
|
Manitoba | Fall protection plan not specifically required |
New Brunswick | Code of practice required when fall protection is required (See A above), and one of the following 3 things is true:
i. Workers are working at height of 7.5 metres or more |
Newfoundland & Labrador | Employers use a fall arrest system or safety net as a means of fall protection |
Nova Scotia | Fall protection is required and maximum fall distance is less than 7.5 metres or more (if the maximum fall distance is < 7.5 metres, only a fall protection safe work procedure is required) |
Ontario | Not specifically required |
Prince Edward Island | Fall arrest systems or personnel safety nets are used as a means of fall protection |
Québec | Not specifically required |
Saskatchewan | Workers are at risk of falling 3 or more metres AND there are no guardrails or similar barriers in place |
Northwest Territories & Nunavut | Workers are at risk of falling 3 or more metres AND there are no guardrails or similar barriers in place |
Yukon | Workers are at risk of falling 7.5 or more metres AND there are no guardrails |
