What's the Difference Between Class 1, 2, and 3 Safety Vests?
When working on the job, it is important to be highly visible in order to avoid unfortunate accidents. One of the ways in which OSHA works to protect workers who handle potentially dangerous materials is by mandating that workers wear vests that are rated and approved by the American National Standards Institute, or ANSI. These vests have been designed for the safety of the worker as well as for comfort, to safeguard workers and consumers. Class 1 safety vests are for workers in low impact areas, where traffic flow does not exceed 25 mph and where personnel are working a good distance away from it. Parking service attendants, delivery vehicle drivers, and sidewalk or roadside maintenance workers are examples of jobs who would qualify for a class 1 safety vest. These vests should have a mandatory 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. Vests should be either a safety yellow or safety orange color. Workers who are involved in jobs where there is heavier traffic are required to wear a Class 2 vest. Jobs that require workers to work in areas where there is poor visibility due to weather will also need a more reflective Class 2 safety vest. Class 2 vests will have a minimum of 201 square inches of reflective tape that is 2 inches in diameter. Dimensions of the reflective tape can be 8.373 linear feet of 2-inch tape or 12.2 linear feet of 1 3/3 inch tape. Examples of jobs that require Class 2 vests are airport baggage handlers and ground crew, forestry workers, high-volume parking or toll-gate personnel and law enforcement personnel. Reflective stripes will be over the shoulders and round the middle in either one or two 360º horizontal stripes. Jobs that require workers to be the most visible are ones that put personnel in close contact with heavy traffic. High risk jobs include accident site investigators, emergency responders, railway workers, utility workers, and survey and flagging crews. These workers will often be close to traffic exceeding 50 miles an hour, so it is important for them to be as visible as possible. Class 3 safety vests and garments must have a minimum of 310 square inches of reflective tape that is 12.92 linear feet and 2-inches thick. Class 3 garments also provide more coverage to the arms and legs than do class 1 and class 2 safety vests. It is important to make sure you are wearing the correct safety vest for your job. Avoiding unnecessary accidents and keeping workers safe is the goal of ANSI and OSHA. Always make sure to wear your safety vest, because being visible to motorists can make the difference between an accident free work zone or an accident prone work zone. |
The standard specifies three classes of high-visibility garments based on the wearer's activities. Garment classes are differentiated by the amount of background material required, the width of retroreflective material used and garment design.
|
Class 1: Workers where traffic does not exceed 25 mph and there is ample separation from the traffic. These workers often include parking service attendants, warehouse workers in traffic, shopping cart retrievers and those doing sidewalk maintenance.
|
Class 1: Garment must be relatively conspicuous, with background material equal to 217 in. in total area and retroreflective bands not less than 25mm wide.
|
Class 2: Workers who work near roadways where traffic exceeds 25 mph and workers who need greater visibility in inclement weather. In general, railway workers, school crossing guards, parking and toll gate personnel, airport ground crews and law enforcement personnel directing traffic.
|
Class 2: Greater visibility than the Class 1 garments. Background material must equal 755 in., and the minimum width of retroreflective bands is 35mm.
|
Class 3: Workers with high task loads in a wide range of weather conditions where traffic exceeds 50 mph. The standard recommends these garments for all roadway construction personnel, vehicle operators, utility workers, survey crews, emergency responders, railway workers and accident site investigators.
|
Class 3: Superior visibility–the highest level of conspicuity. Background material must total 1240 in. Garment must have sleeves with retroreflective material between the shoulders and elbows. The width of retroreflective bands shall not be less than 50mm wide.
|
Class E: When high-visibility pants are worn without other high-visibility garments, they are considered Class E. When pants are added to Class 2 or 3 garments, the ensemble is considered Class 3.
