High-Visibility Clothing
The Problem
High-visibility clothing is one of the most effective and simple ways to protect workers operating near vehicles and mobile equipment. However, its effectiveness depends on proper wear, care, and selection. Workers not wearing the correct hi-vis gear — or using faded or damaged garments — are at greater risk of not being seen, which can lead to serious injury or death. Today we’ll cover the importance of visibility, correct clothing classes, and maintenance practices to keep you safe on site.
Identify the Hazards
Safety Practices and Preventative Measures
Understanding Hi-Vis Clothing Classes (CSA Z96):
- Class 1 (Day Use Only): For daylight hours only; does not include retroreflective material.
- Class 2 or 3 (Day/Night Use): Combines fluorescent material with reflective strips for visibility in both day and night conditions.
- Class 3 (Night Use Only): Garments with retroreflective strips designed for night visibility; typically worn with additional lighting or in vehicle exposure areas.
When to Wear Hi-Vis Clothing:
Wear high-visibility clothing when working near:
- Mobile equipment and vehicles
- Public roads or traffic control zones
- Low-light conditions, early morning, or nighttime
- Emergency or temporary work environments
Garment Inspection and Care:
- Daily Checks: Look for tears, loose stitching, dirt, or fading of fabric and reflective strips.
- Replacement Guidelines: Replace any garment that is faded, torn, soiled beyond cleaning, or has damaged reflective tape.
- Proper Fit: Hi-vis gear must fit close but comfortably, be worn as the outermost layer, and be securely fastened (zippers, buttons, Velcro).
Visibility Requirements:
- Daytime: Garments must be clearly visible from 100 metres under natural light.
- Nighttime: Retroreflective tape must reflect light clearly under headlights or artificial light sources.
Real-Life Case or Scenario
On a road construction site last year, a worker was nearly struck by a reversing loader just before sunrise. The worker’s hi-vis vest was faded and difficult to see in the low light. The equipment operator did not notice them in time. A properly maintained Class 2 or 3 vest with reflective tape would have made the worker visible from a distance, preventing the close call.
Employee Responsibilities
- Wear the correct class of high-visibility garment for the job and conditions.
- Inspect your hi-vis gear daily and report or replace any damaged clothing.
- Make sure garments are clean, fastened, and worn as the outermost layer.
- Never modify garments or wear non-compliant clothing when visibility is required.
Employer Responsibilities
Discussion & Questions
- "What class of hi-vis do you usually wear on site?"
- "Have you experienced a close call involving low visibility?"
- "Do you know when to replace hi-vis garments?"
- "Are there any issues with the hi-vis clothing currently provided?"
Encourage open discussion and feedback.
Commitment/Action Plan
Let’s commit to checking our high-visibility garments daily. If your vest is faded or damaged, report it and replace it immediately. If you see a coworker wearing non-compliant gear, speak up — we look out for each other.
Wrap-Up
High-visibility clothing saves lives. Whether you’re on a construction site, roadside, or working near equipment, wearing the right garment can prevent serious injuries. Make visibility a priority — clean, check, and wear your hi-vis properly.
Standards Overview
The Canadian Centre for Occupational Health and Safety (CCOHS) requires employers to ensure workers are highly visible when exposed to mobile equipment, traffic, or low visibility environments.
Hi-visibility clothing must meet CSA Z96 standards for Class 1, Class 2, or Class 3 as appropriate.
Employers are required to provide compliant personal protective equipment (PPE) and maintain it in good condition.
