Hi Vis Clothing is used by all types of workers who rely upon increased visibility for safety. Construction workers, security personnel, parking lot attendants, and many others use hi vis vests, hi vis jackets, and other hi vis gear to make themselves more visible on work sites. Crews that work on highways for everything from road construction to trash clean-up wear hi vis clothing to ensure they do not fall victim to drivers not paying attention. Contrary to popular belief, hi vis clothing is just as important for use during the day as it is at night.
High visibility warning garments, such as hi viz vests, are required by OSHA for highway and road construction workers according to a new letter of interpretation released in October 2009. In 2004 a similar letter was released regarding the safety of road construction workers, but Occupational Safety and Health Review Commission ruled that the letter required that hi vis clothing be worn only where the Federal Highway Administration's Manual on Uniform Traffic Control Devices mandated their use.
To further ensure the safety of highway workers, OSHA has now issued a letter stating that ALL workers must wear hi vis clothing such as vests and shirts regardless of whether or not the MUTCD requires them. "Highway construction workers should not suffer serious or fatal injuries simply because they could not be seen," according to OSHA acting Assistant Secretary of Labor Jordan Barab. "Requiring the use of reflective vests is essential to help prevent workers from being injured or killed." OSHA recognizes the importance of wearing Hi Vis Safety Clothing in highway and road construction zones due to the dangers posed by traffic in the area.
