What does the different classification of Hi-Vis clothing mean?

Classification of garments


The garments specified in the Australian Standard AS/NZS4602.1:2011 are classified as follows:

Class D – a garment designed for daytime use only. Class D garments are intended to provide the wearer with high visibility under daylight viewing conditions and generally not effective when viewed under artificial light.


Class N – a garment designed for night-time use only.


Class D/N – a garment designed for both day and night use, comprising retroreflective elements on a fluorescent or other non-retroreflective high visibility background material.


This means, if you are working during the day under sunlight, you would only need a Class D garment. At the same time, if your job takes you from day to night, or underground, you would need a class D/N garment.


UV Protection

If your employees will be exposed to direct sunlight during the course of their work duties, you need to make sure they’re safe with UV Protection Workwear.

These garments should have Ultraviolet Protection and must comply with Australian Standard AS/NZS4399 (UV Protection). For employees in sun exposure, the UPF rating of safety garments should be in the 40-50+ Excellent Category.
