High visibility clothing is an essential safety measure for workers who are exposed to potential hazards in low light or poor visibility conditions These garments are designed to increase the wearer’s visibility and to reduce the risk of accidents and injuries There are different classes of high visibility clothing, each designed for specific environments and visibility requirements.
The American National Standards Institute (ANSI) sets the standards for high visibility clothing in the United States The ANSI/ISEA 107 standard specifies three classes of high visibility clothing based on the level of visibility they provide Let’s take a closer look at each class:
1 Class 1
Class 1 high visibility clothing is designed for use in low-risk environments where there is plenty of separation between workers and moving vehicles with speeds not exceeding 25 mph This class of clothing is suitable for workers who are working off-road or in parking lots Class 1 garments must have a minimum of 155 square inches of retroreflective material and 540 square inches of background material.
Examples of Class 1 high visibility clothing include safety vests, T-shirts, and jackets These garments are typically lime or orange in color to maximize visibility during the day and at night Class 1 clothing is not suitable for workers who are exposed to high-speed traffic or who work in areas with poor visibility conditions.
2 Class 2
Class 2 high visibility clothing is designed for use in moderately hazardous environments where workers are exposed to traffic with speeds between 25 and 50 mph This class of clothing provides better visibility than Class 1 garments and is suitable for workers who are directing traffic or working in road construction zones how many classes of high visibility clothing are there. Class 2 garments must have a minimum of 775 square inches of background material and 201 square inches of retroreflective material.
Examples of Class 2 high visibility clothing include safety vests with reflective tape around the chest and waist area, as well as jackets and coveralls with reflective striping Class 2 clothing is typically worn by construction workers, utility workers, and emergency responders who need to be highly visible in traffic.
3 Class 3
Class 3 high visibility clothing is designed for use in high-risk environments where workers are exposed to high-speed traffic or complex backgrounds that make them less visible This class of clothing provides the highest level of visibility and is suitable for workers who are working near highways or in inclement weather conditions Class 3 garments must have a minimum of 1240 square inches of background material and 310 square inches of retroreflective material.
Examples of Class 3 high visibility clothing include coveralls with reflective striping on the arms and legs, as well as rain gear with reflective tape around the torso and sleeves Class 3 clothing is typically worn by road construction workers, tow truck drivers, and highway maintenance crews who need to be visible from a distance in all lighting conditions.
In addition to the three classes of high visibility clothing, there is also a supplemental class known as Performance Class E Performance Class E garments are designed to be worn in combination with Class 2 or Class 3 garments to provide additional visibility These garments must have a minimum of 465 square inches of background material and 107 square inches of retroreflective material.
In conclusion, high visibility clothing plays a crucial role in keeping workers safe in low light and poor visibility conditions By understanding the different classes of high visibility clothing and choosing the right garment for the specific work environment, employers can help reduce the risk of accidents and injuries Whether it’s a Class 1 safety vest for parking lot attendants or a Class 3 coverall for highway maintenance crews, high visibility clothing is a simple yet effective way to improve worker safety and visibility on the job.
