Class 3 hi vis is a type of high-visibility clothing that is designed to provide maximum visibility to workers who work in high-risk environments. These garments are typically used by workers who work in low-light or dark environments, where visibility is critical for safety. Class 3 hi vis garments are the highest level of visibility in the ANSI/ISEA 107 standard, which sets the minimum requirements for high-visibility clothing.

In many work environments, such as construction sites, road works, and railway maintenance, workers are exposed to hazards that can cause serious injury or even death. In these environments, visibility is key to ensuring the safety of workers. Class 3 hi vis garments are designed to provide maximum visibility to workers, making them easier to see and reducing the risk of accidents.

Class 3 hi vis garments are typically made from fluorescent material that reflects light, making the wearer visible even in low light conditions. These garments often feature reflective tape or other reflective material that increases visibility in the dark. The garments are available in a variety of styles, including vests, jackets, and pants, to suit different working environments.

The ANSI/ISEA 107 standard defines three classes of high-visibility clothing, with class 3 being the highest level of visibility. Class 3 hi vis garments are designed for workers who require the highest level of visibility, such as those who work in high-speed traffic areas or in areas with low visibility due to weather conditions. Class 3 hi vis garments must cover a larger area of the body than class 1 and class 2 garments and must include sleeves and pants in addition to a vest or jacket.

The ANSI/ISEA 107 standard also specifies the minimum amount of fluorescent and reflective material that must be used in class 3 hi vis garments. The fluorescent material must cover a minimum of 1,240 square inches, and the reflective material must cover a minimum of 310 square inches. These requirements ensure that class 3 hi vis garments provide maximum visibility to workers.

In addition to meeting the ANSI/ISEA 107 standard, class 3 hi vis garments must also meet the requirements of other safety standards, such as the NFPA 70E standard for electrical safety. This standard specifies the minimum requirements for protective clothing and equipment for workers who are exposed to electrical hazards.

Class 3 hi vis garments are not only important for the safety of workers, but they are also required by law in many jurisdictions. In the United States, for example, the Occupational Safety and Health Administration (OSHA) requires employers to provide high-visibility clothing to workers who are exposed to traffic hazards or who work in low-light conditions. Failure to comply with these regulations can result in fines and other penalties.

Employers have a responsibility to provide their workers with the necessary safety equipment, including class 3 hi vis garments. Employers should ensure that their workers are properly trained in the use of high-visibility clothing and that the clothing is regularly inspected and maintained to ensure that it remains in good condition.

Workers also have a responsibility to wear the high-visibility clothing provided to them by their employers. Workers should ensure that their clothing fits properly and is not damaged or worn out. They should also wear the clothing at all times when required, even if they are only working for a short period of time.

In conclusion, class 3 hi vis garments are an important piece of safety equipment for workers who work in high-risk environments. These garments provide maximum visibility to workers, reducing the risk of accidents and injuries. Employers have a responsibility to provide their workers with the necessary safety equipment, including class 3 hi vis garments, and workers have a responsibility to wear the clothing provided to them.
