Construction Site Safety — Traffic Control Zones in Canada
Construction Site Safety — Traffic Control Zones (Canada)
1) Typical Canadian work zone layout
- Advance warning area: uses 3–4 signs spaced by road speed. Example: “Road Work Ahead,” “Lane Closed,” “Merge Left.”
- Transition area: delineated by cones or posts tapering traffic.
- Activity area: workers, machinery, material storage. Protect with barriers and warning lights.
- Termination area: return traffic to normal flow, maintain line of sight for re-entry.
2) Essential equipment list
- Traffic cones (reflective, weighted base)
- Barriers & barricades (water-filled or interlocking)
- Portable warning signs (EN/FR, foldable frames)
- Solar lamps / flashers (steady or blinking)
- High-visibility jackets (CSA Z96 Class 2+)
- Temporary fencing / mesh barriers
- Speed reduction & “Men at Work” boards
- First-aid kit and fire extinguisher
3) Traffic cone & delineator spacing
| Speed (km/h) | Taper cone spacing | Work zone cone spacing | Notes |
|---|---|---|---|
| ≤ 40 | 5 m | 10 m | Urban & parking areas |
| 60 | 10 m | 15 m | Arterials |
| 80 | 15 m | 30 m | Highways |
Always close the taper with a cone line that drivers can read under headlight beam distance.
4) Signs & boards — placement and height
- Mount temporary signs at 1.5–2.2 m bottom height for city roads; 1.2 m in work zones with barriers.
- Use HIP or DG reflective sheeting for night visibility.
- Ensure bilingual (EN/FR) wording where required by provincial or federal rules.
- Angle signs toward driver approach for better retroreflection.
5) Barriers, barricades & fencing
- Plastic water barriers: use interlocking models with reflective panels; fill ⅔ with water for stability.
- Metal barricades: ideal for pedestrians at short-term events or sidewalk diversions.
- Fencing: add safety mesh to mark boundaries, prevent debris from entering traffic lanes.
6) Flaggers and EN/FR communication
- Flaggers must wear CSA Z96 high-vis apparel and use paddles displaying “STOP / SLOW” in English and French.
- Position flaggers to be visible to both directions; stand on shoulder, not live lane.
- Coordinate hand signals and radio codes before each shift.
7) Night work & lighting standards
- Use solar warning lamps at all tapers and barrier ends.
- Maintain illumination ≥ 10 lux across active area; glare shields for traffic-facing lights.
- Retroreflective materials must be visible from ≥ 150 m under headlights.
8) Pedestrian detours & safe walkways
- Provide temporary sidewalks or fenced corridors with reflective mesh or rails.
- Use portable ramps where curbs are interrupted; minimum width 1.2 m.
- Mark detour routes in both EN/FR; include accessible signage and tactile warning strips if required.
9) Common setup mistakes
- Using faded or dirty cones—poor visibility under headlights.
- Placing signs too close to hazard (no reaction distance).
- Unprotected flaggers or equipment behind single cones.
- Improper taper length—drivers merge too late.
10) Legal / compliance notes (Canada)
This page is informational and not a legal substitute for the Manual of Uniform Traffic Control Devices for Canada (MUTCDC), provincial highway standards, or the Occupational Health and Safety Act requirements. Always follow the official Ministry of Transportation (MTO, MTQ, etc.) guidelines for work zone layout, signage sequence, and worker protection.
Where contracts or municipal permits specify signage spacing, taper length, or device types, those documents prevail.
