High Visibility Vests: What You Need to Know

Every year, there is news about situations where pedestrian workers were accidentally hit by drivers who did not see them until it was too late to change course. These incidents are devastating but there are ways to reduce these occurrences.

High Visibility Vest

High visibility clothing is a form of Personal Protective Equipment (PPE) which has reflective properties that make it easily identifiable in any condition (especially conditions which create poor visibility). High visibility (“Hi-Vis”) vests, (or construction safety vests), is colored brightly, sometimes fluorescent, and accentuated with silver reflective tape which makes it easy for operators or drivers of motor vehicles to see the wearer from a distance in bad weather and after dark. High visibility clothing has become a symbol for situations requiring extreme caution. It is associated with many types of hazardous work environments, not limited to emergency services, road maintenance, and the construction industry where it is imperative to be seen in all kinds of conditions.

Occupational Health and Safety guidelines require that everyone working in dimly lit or adverse weather conditions has to wear “Hi-Vis” clothing. Additionally, High Visibility Vest is among the vital personal protective equipment (PPE) OSHA required employers to provide whenever necessary to protect employees against workplace hazards capable of causing injury or impairment.

High Visibility Vest Color Codes

Safety jackets/vests are sometimes color-coded according to the environment in which they will be worn. Construction workers and emergency services personnel usually wear lime green, fluorescent orange, or lemon yellow reflective safety vests. Orange is okay for traffic traveling more than 25 miles per hour (mph), while yellow is used where nearby traffic is going to exceed 55 mph.

Moreover, fluorescent green, yellow, and orange are easily visible in the daytime. During the evening hours, the reflective tape helps the wearer become more visible because the tape is reflected brightly in the headlights of passing automobiles. If the tape is affixed to parts of the body that are in motion, like the legs of cyclists, this increases their visibility considerably.
