What ANSI/ISEA 107 requires
ANSI/ISEA 107 is the American standard for high visibility apparel. It sets minimum areas of fluorescent background material and retroreflective tape, and it splits garments into performance classes based on how much of each they carry.
Fluorescent material handles daylight visibility. Retroreflective tape handles headlights at night. A garment needs both, and a vest that has faded or has tape peeling at the edges no longer meets the standard regardless of what the label says.
Class 1, 2 and 3, and how to choose
Class 1 is the lowest, for workers well separated from traffic moving under 25 mph. Parking attendants, warehouse yards, some delivery roles.
Class 2 is the working standard for most sites. Required where traffic moves between 25 and 50 mph, or where the work environment is complex enough to make a worker hard to pick out. Almost all road construction, utility and general contracting sits here.
Class 3 carries the most material and requires sleeves, so it comes as a shirt, jacket or a vest with attached sleeves. Required where traffic exceeds 50 mph, in low visibility conditions, and for anyone directing traffic. If your crew works on a highway shoulder, Class 3 is the answer.
One thing worth knowing: any federal-aid highway right of way requires Class 2 minimum under the Federal Highway Administration rule, whatever the speed limit says.
Mesh or solid
Mesh vests breathe. In Florida and anywhere else above 85 degrees for months at a time, this is not a comfort preference. It is what keeps the vest on the worker. The trade is durability and slightly less protection against wind and dust.
Solid polyester vests are tougher, block wind, and hold up better to snagging. They are the right choice in cooler conditions and in work with a lot of contact against rough material.
Break-away, surveyor and specialty cuts
Break-away vests are built with tear-away seams at the shoulders and sides. If the vest catches on machinery or a vehicle, it comes apart rather than pulling the worker with it. Standard practice around moving plant and rail.
Surveyor vests add front pockets, radio loops and pen slots. If your crew carries tools, tablets or radios, a surveyor cut saves them wearing a second garment over the vest. That extra layer usually covers the reflective tape and defeats the point.
Zipper front is easier over layers than hook and loop, and holds up better through repeated washing.
Care, and when to replace
Wash separately from heavily soiled workwear and follow the label wash count. Fluorescent dye fades with UV exposure and with washing, and faded material fails the standard even though the garment looks intact.
Retire a vest when the fluorescent color has visibly dulled, the reflective tape is cracking or lifting, or there are tears across the tape. Most sites replace annually, sooner for crews working outdoors year-round.
Buying hi-vis vests for a crew
Size up rather than down. Vests get worn over jackets, harnesses and cold weather layers, and a vest that will not close over a jacket ends up unworn in December.
Custom logo printing is available on most of our hi-vis range, which matters where site access depends on visible company identification. Send us your headcount, class requirement and artwork and we will quote volume breaks on the full order.
Frequently Asked Questions
What is the difference between a Class 2 and Class 3 safety vest?
Class 3 carries more fluorescent and reflective material and requires sleeves. Class 2 is the standard for most construction and road work. Class 3 is required above 50 mph, in low visibility, and for flagging.
Does OSHA require high visibility vests?
OSHA requires employers to protect against struck-by hazards, and the Federal Highway Administration requires Class 2 minimum on federal-aid highway right of way. In practice, any work near moving vehicles calls for hi-vis.
Are mesh safety vests ANSI compliant?
Yes, when they carry the required background and reflective material for their class. Mesh is a fabric choice, not a compliance shortcut.
How often should safety vests be replaced?
When the fluorescent color has dulled, the tape is cracking or lifting, or the garment has passed its labeled wash count. Most outdoor crews replace annually.
What is a break-away safety vest?
A vest with tear-away seams at the shoulders and sides, so it separates if it snags on machinery or a vehicle instead of pulling the worker in.
Can you print our logo on safety vests?
Yes, on most of our hi-vis range, with the artwork placed so it does not cover reflective tape. We can quote it alongside a bulk order.
