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 plant. 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
- Low Visibility: Workers blending into surroundings or not being seen by machine operators in time.
- Faded or Damaged Garments: Poor reflectivity or bright colour fading reduces visibility.
- Incorrect Fit: Oversized or baggy garments may catch on equipment or create entanglement hazards.
- Wrong Garment Class: Wearing Class D (day only) clothing when Class D/N (day/night) is required, especially in low-light or high-risk environments.
Safety Practices and Preventative Measures
Understanding Hi-Vis Clothing Classes (AS/NZS 4602.1:2011):
- Class D (Day Use Only): For daylight hours only, does not include retroreflective material.
- Class D/N (Day/Night Use): Combines fluorescent material with reflective strips for visibility in both day and night conditions.
- Class N (Night Use Only): Garments with retroreflective strips for night visibility, worn with additional lighting or vehicle exposure.
When to Wear Hi-Vis Clothing:
Wear high-visibility clothing when working near:
- Mobile plant and vehicles
- Public roads or traffic management zones
- Low-light conditions, early morning or night
- 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 be close-fitting but comfortable, worn as the outermost layer, and securely fastened (zips, 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 roading 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 operator did not notice them in time. A properly maintained Class D/N 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 on the outside.
- Never modify garments or wear non-compliant clothing when visibility is required.
Employer Responsibilities
- Provide compliant hi-vis clothing that meets AS/NZS 4602.1:2011.
- Replace worn, damaged, or faded garments.
- Train workers on hi-vis safety, including inspection and selection.
- Ensure all workers are visible in their work areas.
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 mate 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 machinery, wearing the right garment can prevent serious injuries. Make visibility a priority — clean, check, and wear your hi-vis properly.
Standards Overview
- WorkSafe NZ requires employers to ensure workers are highly visible when exposed to mobile plant, traffic, or low visibility environments.
- Hi-vis clothing must meet AS/NZS 4602.1:2011 standards for Class D, Class N, or Class D/N as appropriate.
- Employers are required to provide compliant PPE and maintain it in good condition.
