ANSI/ISEA 107 Safety Vest Guide: Class 2, Class 3, and Vest Types Explained
High-visibility safety vests help workers stay visible around vehicles, equipment, traffic areas, warehouses, construction sites, road work zones, and industrial environments. For many U.S. buyers, ANSI/ISEA 107 is the key standard used to understand high-visibility safety apparel.
This guide explains ANSI/ISEA 107 safety vest classes, garment types, common vest styles, and how to choose the right safety vest for your crew.
Quick Answer: What Is ANSI/ISEA 107?
ANSI/ISEA 107 is the American National Standard for High-Visibility Safety Apparel. It helps classify high-visibility garments by garment type, performance class, background material, reflective material, and intended use.
For safety vests, the most common terms buyers see are:
- Type O
- Type R
- Type P
- Class 1
- Class 2
- Class 3
- Supplemental Class E
- Hi-vis lime
- Hi-vis orange
- Reflective tape
In most industrial and construction buying situations, customers are comparing Class 2 safety vests, Class 3 safety vests, and different vest styles for the jobsite.
Why ANSI/ISEA 107 Matters
ANSI/ISEA 107 helps buyers compare high-visibility garments more clearly. Instead of choosing only by color or price, buyers can review the vest type, class, background material, reflective material, design, and intended working environment.
High-visibility apparel is commonly used in:
- Road work
- Construction
- Warehouse and logistics
- Utility work
- Public works
- Facility maintenance
- Parking and traffic control
- Landscaping
- Industrial yards
- Visitor safety programs
ANSI/ISEA 107 Vest Types Explained
ANSI/ISEA 107 uses garment types to describe the general work environment and exposure level.
Type O Safety Vests
Type O stands for Off-Road.
Type O garments are used for workers who need visibility but are not typically exposed to public roadway traffic.
Common applications:
- Warehouse operations
- Facility maintenance
- General industrial sites
- Parking lots
- Yard work
- Equipment areas
- Visitor safety programs
Type O vests are useful where visibility is important, but traffic exposure is lower than road work or public roadway environments.
Type R Safety Vests
Type R stands for Roadway.
Type R garments are used for workers exposed to roadway traffic or moving vehicles and equipment.
Common applications:
- Road construction
- Utility work
- Traffic control
- Construction near vehicles
- Loading dock areas
- Work zones
- Public works
Type R safety vests are common for construction crews, contractors, road work teams, and workers around moving equipment.
Type P Safety Vests
Type P stands for Public Safety.
Type P garments are designed for emergency responders and public safety professionals.
Common applications:
- Police
- Fire
- EMS
- Emergency response
- Incident management
- Public safety operations
Most industrial buyers focus on Type O and Type R. Public safety teams may require Type P depending on their role and agency requirements.
ANSI Class 1, Class 2, and Class 3 Explained
ANSI performance classes describe the amount and configuration of high-visibility and reflective material used in the garment.
Class 1 Safety Vests
Class 1 provides the lowest level of high-visibility coverage.
Common use cases:
- Off-road work
- Low traffic exposure
- Parking lots
- Warehouse yards
- General facility use
Class 1 is less common for construction and road work buying compared with Class 2 and Class 3.
Class 2 Safety Vests
Class 2 provides more high-visibility coverage than Class 1 and is one of the most common choices for construction, warehouse, utility, and road-adjacent work.
Common use cases:
- Construction sites
- Roadside work
- Warehouse and logistics
- Utility crews
- Survey crews
- Facility maintenance
- Traffic control support
- Contractor teams
Class 2 safety vests are often selected when workers need enhanced visibility around moving vehicles, equipment, or busy jobsites.
Class 3 Safety Vests
Class 3 provides the highest level of visibility among standard high-visibility performance classes.
Common use cases:
- High-speed road work
- Low-light conditions
- Poor weather
- High-risk traffic exposure
- Utility work
- Public works
- Emergency response support
- Large jobsites with heavy equipment
Class 3 garments typically provide more visible coverage and are used when workers need to be seen from greater distance or in more complex environments.
Class 2 vs Class 3 Safety Vests
The most common buyer question is whether to choose Class 2 or Class 3.
Class 2 is often suitable for:
- General construction
- Warehouses
- Facility teams
- Contractors
- Survey crews
- Road-adjacent work
- Equipment areas
Class 3 is often considered for:
- High-speed traffic areas
- Poor visibility
- Night work
- Low-light work
- Heavy equipment zones
- Road work crews
- Utility and public works teams
Simple rule:
Choose Class 2 for general high-visibility needs. Choose Class 3 when visibility risk is higher, traffic exposure is greater, or the jobsite requires more visible coverage.

The best color depends on jobsite background, visibility needs, employer preference, and applicable requirements.
How to Choose the Right Safety Vest
Use these questions before buying safety vests for your team:
1. Where will the vest be used?
For warehouses or controlled facilities, Type O or general high-visibility vests may be suitable. For roadway or vehicle exposure, Type R is commonly used.
2. Is there traffic or heavy equipment?
If workers are near moving vehicles, trucks, forklifts, loaders, or road traffic, choose a vest with stronger visibility and an appropriate ANSI class.
3. Is the work done at night or in low light?
For night work, poor weather, or low-light environments, Class 3 may be considered.
4. Does the worker need pockets?
Choose surveyor vests for supervisors, inspectors, field crews, and workers who carry tools, radios, notepads, or small equipment.
5. Is the vest for visitors?
Visitor vests should be simple, easy to issue, and easy to identify.
6. Do you need custom branding?
Custom logo safety vests are useful for contractors, warehouses, industrial teams, and large crew programs.
