Retroreflective tape sends light back towards its source rather than scattering it. There are two main types:

• Glass-bead tape — millions of microscopic glass spheres with a mirrored backing. Flexible, soft and the most common choice on garments.
• Microprismatic tape — tiny moulded prisms that return more light and stay bright when wet; usually stiffer and used on rainwear and high-risk roadway garments.

Tape can be sewn on, heat-applied as continuous or segmented strips (segmented tape flexes and breathes better), or printed. Because the light is returned to the driver's eyes, the wearer appears very bright to the driver even though the tape looks grey in daylight.

The US consensus standard is ANSI/ISEA 107; the current edition is ANSI/ISEA 107-2020. It defines three garment types and four performance classes:

• Type O (off-road) — Class 1 only, for workers not exposed to traffic, e.g. warehouses and parking lots.
• Type R (roadway) — Class 2 or Class 3, for workers exposed to traffic in the right-of-way or near heavy equipment.
• Type P (public safety) — Class 2 or Class 3, for police, fire and EMS, with options such as breakaway features and access to equipment belts.
• Class E — supplemental items such as trousers and shorts. Worn with a Class 2 or 3 top, the ensemble is rated Class 3.

Minimum areas in the smallest size are roughly: Class 1 — 217 sq in background / 155 sq in reflective; Class 2 — 775 / 201; Class 3 — 1,240 / 310 plus sleeve coverage.

Regulation: the Federal Highway Administration rule 23 CFR 634 and the MUTCD require workers within the right-of-way of federal-aid highways to wear ANSI/ISEA 107 Class 2 or Class 3 apparel, and OSHA enforces traffic-control requirements on construction sites through its reference to the MUTCD. There is no single OSHA standard that sets hi vis garment requirements by itself.

In Europe the standard is EN ISO 20471:2013 + A1:2016. Garments are classified by the minimum area of materials in the smallest size:

• Class 1 — 0.14 m² fluorescent background and 0.10 m² reflective material.
• Class 2 — 0.50 m² background and 0.13 m² reflective material.
• Class 3 — 0.80 m² background and 0.20 m² reflective material, with coverage of the torso and either sleeves or legs.

Permitted fluorescent colours are yellow, orange-red and red. Hi vis clothing is Category II PPE under the EU PPE Regulation (EU) 2016/425, so a garment needs an EU type-examination certificate from a notified body before it can carry the CE mark. In Great Britain the equivalent is UKCA marking under the retained PPE regulation. The garment label shows the pictogram, the class and, where tested, the maximum number of wash cycles.

Canada uses CSA Z96, which is similar in principle to ANSI but has its own tape layouts — including the distinctive "X" on the back for many Class 2 and 3 garments. Australia and New Zealand use AS/NZS 4602.1, which separates day (D), night (N) and day/night (D/N) garments; the night requirements differ from ANSI and EN layouts. Many Middle East and Asian buyers accept EN ISO 20471 or ANSI/ISEA 107. Always tell your supplier which market the garments are for, because the tape layout is designed around the standard.

The class should match the risk: how fast traffic moves, how close it is, how complex the background is and whether work happens at night.

• Class 1 — low-risk areas away from traffic: warehouses, car parks, shopping trolley retrieval.
• Class 2 — work near traffic or moving equipment, poor weather or complex backgrounds: most construction, roadwork, utilities, ports and logistics yards.
• Class 3 — high-speed traffic, night work, low visibility, or where the worker must be recognised as a human figure at distance: highway crews, flaggers at night, emergency responders.

Your site rules, contract or local regulation always take priority. A vest alone can reach Class 2; for Class 3 you need sleeves (jacket, long-sleeve shirt, coverall) or a combination of top and Class E trousers.

All three are recognised fluorescent colours, so the choice is about contrast with the working environment. Orange-red stands out against green vegetation, snow and many work zones; yellow-green is very conspicuous in urban settings, at dusk and on overcast days. Some industries have conventions — orange is common on European rail and many US highway crews, yellow on construction sites. If your crews work in mixed environments, choose the colour that contrasts most with the most common background.

It can. Printing or embroidery on the fluorescent background reduces the visible background area, and anything placed over reflective tape reduces the reflective area. A good manufacturer calculates logo size and position during design, so the smallest size in the range still meets the minimum area for its class. Reflective logos and lettering are a good option because they add night visibility rather than reducing it.

• Weak colour: untested fluorescent fabric can fail chromaticity and luminance requirements and fade quickly in sunlight.
• Poor tape: cheap tape returns far less light and may crack or peel after a few washes, so night visibility collapses.
• Too little area: undersized garments or narrow tape cannot reach the class the job requires, even if they look similar.
• Bad fit: loose or tight garments get caught or are taken off by workers, and a vest that is not worn protects no one.

Buy from suppliers who can show test reports for the specific style, fabric and tape, and check the label for standard, class and care instructions.

Service life depends on wear, sunlight, dirt and washing, not on a fixed date. A rough guide often quoted for garments worn daily is around six months, while occasional-use garments last much longer. Replace garments when the fluorescent colour has faded, the tape is cracked, peeling or dull, the garment is permanently soiled, or it has reached the maximum wash cycles on the label.

To extend life: wash inside out at the temperature on the label, avoid bleach and fabric softener, do not tumble dry on high heat or iron the tape, and store garments away from direct sunlight.

Yes, but each property has its own standard. Rainwear is commonly tested to EN 343; cold-weather garments to EN 342 or EN 14058; flame-resistant garments to EN ISO 11612, NFPA 2112 or arc standards such as IEC 61482-2 and ASTM F1506; antistatic garments to EN 1149-5. For FR hi vis, every component — fabric, tape, thread, zip and logo — must be flame-resistant, so these garments are built from certified FR materials rather than standard hi vis.
