ANSI Class 1, 2 or 3?
ANSI/ISEA 107 is the standard for high visibility clothing used to protect workers from vehicular traffic. There are three performance levels for high visibility, reflective clothing:
CLASS 1 is for use where occupational activities: permit full and undivided attention to approaching traffic; provide ample separation between the pedestrian worker and vehicle traffic; permit optimum visibility in backgrounds that are not complex, and where; vehicle and moving equipment speeds do not exceed 25 mph.
Examples of workers who could use Class 1 may include: workers retrieving shopping carts from parking areas; workers directing vehicle operators to parking or service locations; workers exposed to warehouse equipment traffic.
CLASS 2 is for use where: greater visibility is desired during bad weather; there are complicated backgrounds; workers are performing tasks that draw their attention away from approaching vehicle traffic; vehicle or moving equipment speeds from 25 mph to 50 mph; work activities take place closer to vehicle traffic.
Examples of workers who could use Class 2 may include: roadway construction workers; utility workers; survey crews; school crossing guards; railway workers; forestry workers; parking or toll gate workers; airport baggage & ground crew.
CLASS 3 is for use where: workers are exposed to vehicle speeds in excess of 50 mph and/or reduced sight distances; the worker and vehicle operator have high task loads, clearly placing the worker in danger; the worker must be visible through the full range of body motions at a minimum of 390 meters (1,280 feet) and must be identifiable as a person.
Examples of workers who could use Class 3 include: roadway construction workers; utility workers; survey crews; flagging crews.
