When your team is in the field, your workers need to wear safety vests, or high-visibility vests. These vests are made with highly reflective materials that keep individual workers visible, especially at night. All safety vests are rated and approved by the American National Standards Institute (ANSI). Safety vests are classified as Class 1, Class 2, or Class 3, based on the amount of both reflective material and high contrast (orange or lime color) fabric making up the vest. The degree of reflectivity in the tape and intensity of the background fabric colors are specified in the ANSI standard. The more hazardous your workplace, the more visible your team needs to be.

Learn about the differences between the classes of hi-vis vests and when to use each.

Class 1 Safety Vests

Class 1 vests are for those working in low-impact areas. According to OSHA, this includes areas where traffic flow does not exceed 25 mph. Workers should also be stationed a good distance away from the traffic to prevent injury. Class 1 vests are typically used by parking attendants, delivery drivers, and roadside assistance personnel in low traffic areas.

All class 1 vests should have a minimum of 155 square inches of reflective tape. Dimensions of the reflective tape can be either 6.46 linear feet of 2-inch tape or 9.39 linear feet of 1 3/8-inch tape. The reflective stripes should be around the middle in a 360º stripe and above each shoulder. These vests should also have a bright yellow or orange color.

Class 2 Safety Vests

Those working near heavier traffic and in low visibility areas will need to wear class 2 safety vests. The weather may reduce visibility in these areas and traffic flow may exceed 25 mph. Workers should still be stationed a good distance away from the traffic. Class 2 vests are typically worn by airport workers, high-volume parking or toll booth operators, and forest workers.

Class 2 vests must have a minimum of 201 square inches of reflective tape. Dimensions of the reflective tape can be 8.373 linear feet of 2-inch tape or 12.2 linear feet of 1 3/8-inch tape. Reflective stripes should be over the shoulders and around the middle in either one or two 360º horizontal stripes.

Class 3 Safety Vests

Class 3 vests are reserved for those that are close to high-traffic areas, including site inspectors, emergency responders, railway workers, and utility crews. Traffic in these areas may be close to or exceed 50 mph. Workers typically work right next to the road or in other hazardous areas, so they should be as visible as possible to prevent injury.

These vests must have a minimum of 310 square inches of reflective tape that is 12.92 linear feet and 2-inches wide. This includes a requirement that the worker have a full silhouette outline. Headlights approaching a worker should make plain that this is a person. This means reflective materials on the arms and legs, which far exceeds the standards for Class 1 and Class 2 safety vests.
