Safety Vests: Understanding Lime, Orange, and Beyond

High-visibility safety vests are essential in preventing accidents and improving visibility in hazardous work environments. Most people recognize these vests by their vibrant lime or orange colors, but there’s more to the story. This article explores the history of safety vests, why certain colors dominate, how enhanced visibility vests fit into the picture, and where you can find them at the Traffic Safety Store.

A Brief History of High-Visibility Clothing

Modern safety vests trace their roots to advancements in fluorescent dyes and reflective technology in the 20th century. In the s, Bob and Joe Switzer famously created “Day-Glo” paints through experimentation with fluorescent pigments. By the s, railway workers in the UK were sporting bright orange jackets for track maintenance, and North American road crews soon followed suit. These early efforts helped shape modern safety regulations and awareness. In the United States, the Occupational Safety and Health Administration (OSHA) was established in , laying the groundwork for workplace safety rules. The American National Standards Institute (ANSI) introduced its first high-visibility safety apparel standard (ANSI/ISEA 107) in , standardizing requirements for color, reflectivity, and vest design. Today, many industries—construction, highway maintenance, emergency services, aviation, and more—require ANSI-rated vests to protect workers.

ANSI Safety Vests and Their Purpose

An ANSI safety vest is engineered to improve a wearer’s visibility in high-risk or low-visibility environments. These garments commonly feature fluorescent fabric in lime (yellow-green) or orange, along with reflective striping that catches vehicle headlights or other light sources. By increasing contrast against most backgrounds, ANSI safety vests help drivers and machine operators see workers faster. If you need to purchase ANSI-rated vests for your team, check out the Traffic Safety Store’s Safety Vests collection.

Class 1, Class 2, and Class 3

ANSI categorizes high-visibility apparel into different classes based on coverage and reflective tape:

• Class 1: Minimal coverage; best for low-risk tasks away from busy roadways or moving vehicles.
• Class 2: Increased coverage, commonly used by road crews, construction workers, and surveyors where traffic exceeds 25 mph. View our Class 2 Safety Vests for the most commonly required standard.
• Class 3: Maximum coverage; worn in high-risk areas like highway construction or emergency response on busy roads.

Why Lime and Orange Colors Dominate

Bright lime (yellow-green) and orange are the standard ANSI-approved hues due to the way our eyes perceive color. Research shows these shades appear significantly brighter and more conspicuous in daylight conditions.

Lime (Yellow-Green)

• Peak Visual Sensitivity: The human eye is particularly sensitive to the yellow-green spectrum in daylight.
• High Contrast: Lime vests stand out in both urban and natural settings (forests, fields, cityscapes).

Orange

• Traditional Warning Color: Orange has long been associated with hazard signage (e.g., traffic cones, warning lights).
• Visibility: Contrasts sharply against green foliage, gray pavement, and many common backgrounds.

Both colors are ANSI-compliant if they meet the required fluorescent intensity and reflective striping. The choice often depends on local regulations, environment, or company preference.  

Beyond Orange and Lime: Enhanced Visibility Vests

Not all work environments mandate strict ANSI high-visibility requirements. In such cases, enhanced visibility vests—available in alternative base colors (like black, navy, or red) with reflective accents—may be sufficient. They can be particularly useful for branding, event staff, or settings where full ANSI Class 2 or Class 3 compliance isn’t required. Explore the Enhanced Visibility Vests section at the Traffic Safety Store to find options that blend reflective materials with non-traditional colors. Note that enhanced visibility generally lacks the full fluorescent coverage demanded by ANSI standards. Always verify whether your job site requires ANSI-rated garments before selecting an enhanced visibility vest.

ANSI Red Safety Vests

While lime (yellow-green) and orange are the most familiar ANSI-compliant colors, fluorescent red is also allowed under the ANSI/ISEA 107 standard—so long as it meets the brightness and reflective requirements. ANSI Red is not just a regular “stop-sign” red; it must be sufficiently fluorescent to be highly visible in daylight and low-light conditions. Here’s what you need to know:

• Compliance: To carry an ANSI label, the vest’s red hue must fall within the prescribed chromaticity and luminance ranges (i.e., it must be bright and reflective enough).
• Applications: Some organizations use red safety vests to differentiate roles or departments—for example, supervisors vs. crew members—or to create a distinct visual identity.
• Environmental Contrast: In certain settings, a vivid orange-red or fluorescent red can provide better contrast than standard orange or lime.
• Class Ratings: As with any ANSI vest, red vests can be Class 2 or Class 3 if they have enough background fabric and the required width/placement of reflective striping.
• Less Common, Still Effective: Although fluorescent red vests are less commonly seen than lime or orange, they remain a valid option for jobs that require ANSI-compliant high-visibility apparel.

Whether you choose lime, orange, or red, it’s essential to verify that the vest is truly ANSI/ISEA 107–compliant. Look for labeling that specifies the vest’s class rating and ensure the vendor meets all ANSI specifications.

Key Takeaways

Summary Points

• Historical Roots: High-visibility clothing evolved from s “Day-Glo” discoveries and gained traction in the s.
• ANSI Standards: Set design, color, and reflectivity guidelines for safety vests. Class 2 is the most commonly required.
• Lime vs. Orange: Both are ANSI-approved fluorescent colors. Selection often depends on visibility needs and work setting.

When it comes to workplace safety, it's essential to take all the precautions necessary to prevent injuries. One key piece of safety gear is a safety vest.

But how do you select the right one for your needs? And once you've got it, how do you wear it properly? This post will answer those questions and more. Let's discuss it in detail. 

How To Choose A Safety Vest?

When choosing a safety vest, there are several factors you need to take into account to ensure that you're getting the best possible product for your needs. These include the material the vest is made from, the amount of reflective required, the type of closure, and the number of pockets.

Material

The material of the safety vest is crucial because it will determine how visible you are. If you need to be highly visible, a mesh vest is a good option. However, if you don't need to be visible, then a solid vest will do just fine.

Types Of Closure

The type of closure is also essential. Velcro is a good option if you need to be able to put the vest on quickly. However, if you need a more secure closure, a button or zipper is better.

Choosing by ANSI Type

Consider ANSI classes when looking for high-visibility safety vests. They include:

ANSI/ISEA 107-

American National Standard for High-Visibility Safety Apparel and Accessories – ANSI/ISEA 107- establishes performance requirements, test methods, and labeling requirements for high-visibility and reflective safety apparel and accessories used in occupational settings under conditions where workers are exposed to low-visibility conditions. There are three class levels of garments defined within ANSI/ISEA 107-. The level of the garment is based on the amount of background material and retroreflective material.

For more information, please visit Orange Safety Vest.

Non-ANSI Safety Vests

Non-ANSI compliant vests do not adhere to specific size, shape, or reflectivity standards. These vests can be made from various materials, including polyester, cotton, or nylon. While they may have some reflective tape, they will not have enough to comply with ANSI standards. Non-ANSI safety vests are not recommended for use in any work environment.

Class 2 Safety Vests

Class 2 safety vests are required when workers are exposed to medium-speed traffic. These vests must have 775 square inches of background material and 201 square inches of retroreflective material. The background material must be fluorescent yellow-green, fluorescent orange-red, or white. The reflective vests' material must be white, yellow, or red.

Class 3 Safety Vests

Class 3 safety vests are required when workers are exposed to high-speed traffic traveling over 50 mph. These vests must have 1,240 square inches of background material and 310 square inches of retroreflective material.

Public Safety Vests

Public safety vests are required when workers are exposed to traffic traveling over 50 mph and the worker is performing a task involving both hands. These vests must have 1,240 square inches of background material and 310 square inches of retroreflective material.

Type O (“Off-Road”) – Occupational HVSA for Non-Roadway Use

Type O occupational high-visibility clothing is intended to provide the wearer with enhanced visibility in all lighting conditions when viewed by a person operating a motor vehicle on a roadway. This type of apparel is not intended to provide the wearer with visibility when viewed by someone using off-road vehicles such as agricultural equipment, construction equipment, or other industrial vehicles.

Performance Class 1 (Type O)

Performance Class 1 (Type O) is the minimum level of protection required when working in environments where struck-by hazards are not approaching at roadway speeds. This class provides adequate high-visibility material to differentiate the wearer from non-complex work environments. In these scenarios, operative detection and identification distances can be shorter than in other situations without compromising safety.

Performance Class 2 (Type R or P)

Performance Class 2 includes more high-visibility vests, making them easier to see at greater distances. They also provide better detection and identification than Performance Class 1 vests.

Performance Class 3 (Type R or P)

Class 3 vests are the highest level of protection as they provide the most visibility. These vests must have background and combined-performance materials on both the pant legs and sleeves. This class is ideal for workers exposed to complex backgrounds or who need to be visible from all angles, such as construction workers, utility workers, and flaggers.

FR Vests (Flame Resistant) And Self Extinguishing Vests

FR vests are flame resistant and self-extinguishing. They meet ASTM standards and are ideal for any worker requiring high visibility and protection from flames, sparks, arc flashes, and other possible flammable situations. FR vests are commonly used by utility workers, welders, public safety personnel, oil field workers, first responders, petrochemical refinery workers, and shipyard workers. 

Number Of Pockets

Finally, you need to consider the number of pockets. If you need to carry a lot of gear with you, more pockets are better. However, if you don't need to carry much, fewer pockets will do just fine. Keep these factors in mind when choosing a safety vest, and you'll be sure to get the best possible product for your needs.

About Wearing Safety Vests

Wearing a safety vest is essential for many occupations. Construction workers, utility workers, and others who work around vehicles or in low-visibility conditions need to be visible to prevent accidents. There are a few different ways to wear a safety vest to be effective.

• The most common way to wear a safety vest is by putting it on over the head and securing it at the waist. This method ensures that the vest covers the entire torso and that it will not come off easily. It also allows for easy removal if necessary.
• Another way to wear a safety vest is by putting it on under the arms. This method is often used by law enforcement and security personnel who need to be able to remove their vest if necessary quickly. It also keeps the vest from riding up and exposing the wearer to potential hazards.

No matter how you wear your safety vest, it is essential to make sure that it is visible. A vest that is not visible is not going to do its job. Choose a bright color or a reflective material for your safety vest so that others can see you. Wearing a safety vest is an important part of keeping yourself safe. Make sure that you are wearing yours correctly to be seen and stay protected. 

FAQs about safety vests

What Is The Purpose Of A Safety Vest?

The purpose of a safety vest is to increase the person's visibility to be easily seen by others. This is especially important in work environments where there might be a lot of activity or movement or in low-light conditions.

Who Needs To Wear Safety Vest?

There are no hard and fast rules about who needs to wear a safety vest, but in general, they are most commonly worn by construction workers, police officers, emergency personnel, firefighters, and other first responders. In some cases, employers may require all employees to wear safety vests while on the job site.

What Do Colors Of Safety Vests Mean?

Safety vests are available in various colors, and each color has a different meaning. For example, orange is typically used for construction workers, while green is often used for landscapers. Yellow and white are the most common colors for police officers, and red is often used for firefighters.

How Do I Choose The Right Size Safety Vest?

When choosing a safety vest, it is crucial to select the right size. Vests that are too big or too small can be uncomfortable to wear and impede movement. To find the right size, measure around the chest and waist and consult the sizing chart on the product page.
