Knowing What Class Garment to use is Vital in Getting the Right Protection

Because exposure to vehicular traffic can entail varying levels of danger for workers who are performing tasks in moving traffic zones, there are also varying levels of appropriate high-visibility safety clothing used for protection.  ANSI/ISEA 107 is the standard for that protective apparel which is categorized in Classes 1, 2, and 3.  To be sure you are getting the ultimate protection from your hi-viz wear, follow these guidelines:

CLASS 1 is used when:

• There is ample space between a worker and vehicular traffic
• Full and undivided attention may be given to approaching traffic
• Workers are conspicuous against backgrounds that are not visually complex
• Speeds of moving equipment and motor vehicles do not exceed 25 mph

CLASS 2 is used when:

• Workers are involved in duties where their attention is diverted from approaching vehicles
• Bad weather reduces visibility
• Workers are less conspicuous against a complicated background
• Speeds of moving equipment and motor vehicles range from 25 mph to 50 mph

CLASS 3 is used when:

• Workers must focus all of their attention on the work and not the traffic
• Workers must be conspicuous through a full range of motion/duties performing the task
• Speeds of moving equipment and vehicles exceed 50 mph
