ANSI 107 Class 2 vs Class 3: A Planning Guide for Las Vegas Crews

ANSI/ISEA 107 defines performance classes for high-visibility safety apparel. Project rules may reference the standard. The employer's hazard assessment and current requirements control the selection.

Bighorn Threads coordinates hi-vis apparel programs for road contractors, paving crews, traffic control, utility workers, and signal techs. Your employer selects the required class and garment. Bighorn then coordinates approved decoration through a production partner. See our custom safety vests Las Vegas page for product options.

Class 2: A Mid-Level Visibility Class

Class 2 garments provide more visible material than Class 1 garments. Product designs include vests, shirts, and polos. Confirm the exact garment's current label and manufacturer documentation.

Class 2 may apply to some work around managed traffic, but the employer's hazard assessment controls the choice. Product options include the ML Kishigo 9100 series mesh-back tee, the 1191/1193 Premium Black Series polo, and the Radians ST21 mesh tee. Compare current manufacturer specifications before ordering.

Class 3: Greater Worker Visibility

Class 3 has greater visibility requirements than Class 2. Garment designs provide visibility through the worker's range of motion. The employer selects Class 3 when the hazard assessment and applicable work-zone requirements call for it.

Class 3 may apply to roadway, utility, emergency-response, or low-visibility work. Contract and traffic-control requirements can also affect selection. Compare the current labels for products such as ML Kishigo shirts or jackets before ordering.

Class E: Hi-Vis Pants

Class E is a supplemental classification used for garments such as pants. Some Class E and upper-body garment combinations may form a higher-class ensemble. Verify the exact combination against current labels and employer requirements before use.

Decoration Review for Hi-Vis Apparel

Decoration can affect the visible background and retroreflective areas needed for a garment's class. Do not assume a placement is acceptable. Use the current manufacturer instructions and obtain employer approval for the exact method and placement.

Bighorn coordinates only employer-approved products and decoration requests through production partners. Before production, the employer and garment manufacturer must approve the proposed method and placement. Documentation availability depends on the manufacturer and partner and is confirmed in writing.

Questions for Your Safety Lead

• Which performance class does the hazard assessment require?
• Which contract, traffic-control, or site rules apply?
• Does the selected SKU carry the required current label?
• Will a proposed garment combination form the required ensemble?
• How will hot-weather comfort be addressed without changing the approved product?
• Does another hazard require a separately rated garment or protective system?
