The use of safety vests is one of the easiest ways to help keep workers safe, especially for roadside jobs. They can help prevent common accidents, such as vehicles striking workers at the job site, whether those vehicles are driven by other workers or commuters. Though the vests seem simple, there are a few different categories, and vests are catered to specific types of jobs.
Class 1 Vets
A Class 1 vest, which is often yellow, orange or lime green, is made for any low traffic areas. Though these can be helpful, since the risk in those areas is low, they don't have to conform to American National Standards Institute (ANSI) guidelines, and they don't have to get ANSI approval before being issued.
Class 2 Vests
Class 2 vests are used for projects where cars are expected to pass at a speed of 25 mph at the most. The risk is higher here, so these vest do need ANSI approval.
Class 3 Vests
A Class 3 vest likewise needs to have full ANSI approval, and it is used in any place where traffic is expected to be moving at 50 mph or faster. Therefore, they're used on jobs near major highways and interstates.
In addition to these classes, there are lighted vests for work at night, waterproof vests for outdoor work, special construction vests for higher visibility around machinery, and vests with safety harnesses.
If you were injured in a workplace accidents and you were not given the proper safety vest—or not given one at all—you may be able to seek compensation for your injuries in New Jersey.
