A First Line of Defense A First Line of Defense Danger is everywhere on a construction site. Cars, tractor-trailers and trucks race past, often within inches of workers. Impatient, distracted drivers swerve outside their lanes, rarely slowing down to a safe speed. Visibility is limited for operators of heavy equipment and trucks, while noise makes it difficult for workers to hear approaching vehicles and equipment. Even the most attentive drivers and equipment operators frequently find it difficult to see workers on foot.
Much work is done at night or when light levels are low at dawn, dusk and during inclement weather.
Visibility problems are the cause for many of the deaths and injuries that happen when workers get hit by vehicles or mobile equipment. High-visibility apparel serves as a first line of defense to protect workers against being struck by a vehicle or piece of equipment operated by someone who otherwise would not be able to see them during the day or at night. Meeting Every Worker Visibility Need ISEA members lead the way in developing high-visibility apparel to meet the safety needs of every industry. High-visibility materials can be used in a limitless variety of apparel designs, ranging from vests and coveralls that are fixtures in construction sites, to highly specialized products that meet specific needs. Working closely with the construction industry, federal and state highway departments, and workers, ISEA and its members create new designs and innovations in high-visibility apparel that optimize worker safety.
