Visibility is essential to workplace safety, especially in specific industries and work environments. High-visibility colors are the best way to ensure workers stay safe while on the job. There’s a variety of high-visibility safety apparel out there, so knowing which one to choose for your job or your employees is critical to maintaining a safe workplace.
The Importance of Visibility in Safety Gear
High-visibility clothing is essential to keeping workers safe in work zones or sites. Many workers in risky industries must wear a high-visibility color to help prevent being struck by equipment or cars passing by.
The Occupational Safety and Health Administration (OSHA) reports that in construction alone, 75% of workplace injuries, including fatalities, are caused by low visibility. High-visibility colors stand out to the human eye, making those who wear them easier to see. When they’re easily spotted, avoiding an accident involving the workers is easier.
Types of Hi-Vis Colors
Several types of high-visibility colors are available for workers to wear. Each serves a specific purpose but aims to increase visibility in low-light conditions. There are four standard fluorescent colors:
- Yellow-Green (Type G): Sometimes called safety yellow, it’s the most visible color to the human eye. It’s excellent for dawn and dusk conditions.
- Orange-Red (Type R): Safety orange contrasts against natural backgrounds and is visible in bright daylight.
- Lime-Yellow: Visible in various light conditions and used by emergency personnel.
- Pink (Type P): Less visible but popular for workers who need to stand out from other workers or people.
In addition to fluorescent colors, there are reflective components used on these safety clothes:
- Specialized Coatings: Enhance durability and maintain reflective properties.
-
Glass Bead Technology: Allows for consistent retroreflective over wide viewing angles.
Prismatic Reflective Tape: Offers the best brightness and longevity. - Combined Performance: Integrate both reflective and fluorescent properties for optimal visibility.
Factors to Consider When Choosing Hi-Vis Colors
Choosing high-visibility clothing requires careful consideration of all the critical factors. There are several things to consider when choosing the best safety colors for the job.
Environmental factors:
- Weather patterns and seasonal changes
- Ambient light levels through work shifts
- Distance requirements for visibility
- Background colors and textures in the work zone
- Potential obstacles or visual interference
Worker considerations:
- Range of motion
- Comfort and breathability
- Duration of wear
- Compatibility with other personal protective equipment (PPE)
- Layering needs for varying weather conditions
Industry-specific requirements:
- Type of work being performed
- Proximity to moving vehicles or equipment
- Duration of exposure to various conditions
- Integration with other safety equipment
- Required compliance with industry standards
Choosing Hi-Vis Colors for Different Environments
Different work environments require different high-visibility gear. Urban and industrial settings have similar requirements but slightly differ, while rural settings are quite different from the other two.
Urban environments:
- Multiple reflection points for different light sources
- Fluorescent yellow-green is great against asphalt and concrete
- Contrast bands to break up the urban background
- Reflective striping patterns to enhance visibility in shadowed areas
Industrial settings:
- Robust materials to hold up against harsh conditions
- Combined color schemes to maximize visibility
- Enhanced durability for prolonged use
- Durable materials to withstand harsh conditions
Rural settings:
- Fluorescent orange-red is great against vegetation
- Broader coverage areas to maintain visibility at farther distances
- Weather-resistant materials
- Enhanced reflective patterns for limited artificial lighting
Hi-Vis Color Combinations for Enhanced Visibility
Whether working on construction sites or other potentially hazardous environments, you can combine high-visibility colors to maximize visibility.
Primary combinations:
- Pattern variations for specific applications
- Yellow-green base with orange-red contrast panels
- Dual-tone designs for complex environments
- Reflective silver striping on fluorescent backgrounds
Performance-enahnced designs:
- Multi-angle visibility features
- Movement-point reflective patterns
- Activity-specific enhancement patterns
- Anatomically-optimized pattern placement
Regulations and Standards for Hi-Vis Colors
High-visibility apparel is highly regulated to ensure the safety of all workers who need to wear it in different industries. In the United States, the American National Standards Institute (ANSI) and the International Safety Equipment Association (ISEA) have created guidelines for high-visibility gear. Their updated requirements are under the ANSI/ISEA 107-2020:
- Performance Class 1: Minimum visibility requirements
- Performance Class 2: Enhanced visibility requirements
- Performance Class 3: Highest visibility requirements
- Performance Class E: Additional garments for full compliance
Different industries will have different regulations on which Hi-Vis attire workers must wear. For example, construction workers wear class 2 or 3 depending on their work zone. Those in emergency services are often in class 3.
Seasonal Considerations for Hi-Vis Colors
In addition to regulations, the seasons can impact the appropriate high-visibility color for workers. This will vary from climate to climate, but some good rules of thumb exist.
Winter:
- Compatibility with cold-weather gear
- Enhanced reflective requirements for shorter daylight hours
- Durability against winter weather
- Snow and ice reflection considerations
Summer:
- UV protection and color stability
- Heat stress mitigation
- Ventilation and comfort features
- Moisture management features
Testing Hi-Vis Materials and Colors
All high-visibility gear goes through testing to ensure its visibility is effective and durable enough to last for several wears and washes. The clothing undergoes physical and environmental testing:
- Reflective performance management
- Wash cycle durability
- Colorfastness evaluation
- Abrasion resistance assessment
- Weather exposure simulation
- UV degradation assessment
- Temperature cycling
- Chemical resistance evaluation
Tips for Maintaining Hi-Vis Gear
It doesn’t matter what working environment someone’s in. Proper maintenance is the best way to ensure that Hi-Vis clothing remains effective for a long time. Some tips for maintaining high-visibility clothing are:
- Create and stick to an inspection schedule
- Use proper stain removal techniques
- Only use a detergent that won’t deteriorate the material and reflective material
- Use a professional high-visibility gear cleaning service
- Store the clothing in temperature-controlled environments
- Use UV protection measures
- Properly fold the gear to prevent wear-and-tear
- Rotate the use of each safety piece to ensure one’s not used more than another
Real-World Applications of Hi-Vis Colors
Construction, road work, railway, emergency services, and many other industries utilize safety colors for employees and visitors, especially in low-lighting conditions. Here are some examples:
- Visitors and vendors wearing safety pink or red vests
- Construction workers wearing neon yellow or green gear
- Airport personnel wearing fluorescent orange while loading baggage or on the tarmac
The Role of Hi-Vis Colors in Worker Safety Training
Incorporating Hi-Vis clothing training into a training program in hazardous industries or worksites can help increase awareness and keep workers safe. Some training components to include are:
- Replacement guidelines
- Selection criteria
- Proper wear and use
- Emergency procedures
- Maintenance requirements
