AS/NZS Standards For High Visibility Safety Garments

The new Australian and New Zealand Standard AS/NZS 4602.1:2011 High visibility safety garments — Garments for high risk applications supersedes the 1999 standard. It relates to the design of the garment and specifically the amount of high visibility material used.

The new standard calls for garments to have an unbroken area of fluorescent fabric across the torso, and although the total area of fluorescent fabric is the same as the previous standard, no non-fluorescent fabrics or design features can cut across the torso area. Please note that any changes, alterations or additions such as embroidery or screen printing to the garments may reduce the visibility area for a garment, therefore care should be taken to ensure the garment continues to meet the required safety standards.

Day Only use (Class D):

Garments for Day Only use are designed for daytime work in
environments where there are good levels of lighting. They are
not suitable for work done outside of daylight hours.

A Day only compliant garment must have a minimum 0.2m² of
fluorescent orange or yellow material on the front and also on
the back. High visibility material must encircle the upper body,
and underarm ventilation panels must be no more than 10cm
wide x 10cm high.

Day/Night use (Class D/N):

Garments for Day/Night use are designed for both daytime and nighttime work, or for work environments where the light levels are poor. A Day/Night compliant garment must have a minimum 0.2m² of visible fluorescent orange or yellow material on the front and also on the back.

Fabric under reflective tape is not included in this measurement. High visibility material must encircle the upper body, and underarm ventilation panels must be no more than 10cm wide x 10cm high. A Day/Night garment must also have additional retro reflective material which must be 50mm wide and form an 'H' or 'belt & braces' configuration.
