Hi-Vis Clothing Standards

• Wear hi-vis clothing at all times when on the construction site.
• Select Class 3 garments for work near plant, vehicles, and highways.
• Keep hi-vis clean — wash it regularly to maintain retroreflective performance.
• Replace hi-vis that is faded, torn, or heavily contaminated with dirt or paint.
• Wear Chapter 8 compliant hi-vis when working on or adjacent to public highways.
• Choose hi-vis garments that fit correctly over any other clothing layers.
• Use enhanced retroreflective hi-vis for night working and low-light conditions.
• Ensure hi-vis is visible from all directions — front, back, and sides.
• Store hi-vis properly when not in use to prevent unnecessary degradation.
• Report damaged or missing hi-vis to your supervisor for replacement.

• DON'T work anywhere on site without wearing your hi-vis clothing.
• DON'T wear Class 2 waistcoats where Class 3 garments are required by the risk.
• DON'T continue wearing hi-vis that is faded, torn, or heavily soiled.
• DON'T cover hi-vis with jackets, harnesses, or equipment that hides the material.
• DON'T wear hi-vis that does not meet EN ISO 20471 or Chapter 8 requirements.
• DON'T assume plant operators can see you just because you are wearing hi-vis.
• DON'T use hi-vis as a substitute for proper pedestrian segregation from plant.
• DON'T wash hi-vis with fabric softener — it degrades the retroreflective material.
• DON'T leave your hi-vis in the cab when walking across the site.
• DON'T wear orange hi-vis on rail sites where it conflicts with railway standards.
