A Comprehensive Study on Workforce Safety in Construction Work Zones

The realm of work zones and roadway construction is fraught with potential hazards that range from equipment-specific dangers to human errors and environmental challenges. According to the Federal Highway Administration, there's a work zone injury every 13 minutes and a fatality every 11 hours, highlighting the need for meticulous attention and strategies to mitigate these threats. This study aims to extensively review the existing literature to pinpoint the hazards associated with work zones along with effective strategies to prevent such situations. The methodology consists of an exhaustive review of documents from OSHA, National Highway Institute, Engineering News-Record, and several pivotal organizations, as well as a thorough examination of publications sourced from Google Scholar, ResearchGate, and other academic platforms. Preliminary findings underscore the prominence of the Construction Fatal Four - falling, electrocution, hit-by-object, and caught in/between - as the leading causes of worker deaths at construction sites which accounted for over 58.6% of construction deaths in 2018. The findings highlight a structured hierarchy of hazard protection. At the forefront are engineering controls, which are the most effective; these either eradicate the hazard or establish a barrier safeguarding the worker from potential threats. Subsequently, administrative controls come into play, modifying work procedures to reduce exposure. Concluding the hierarchy is the utilization of personal protective equipment, serving as the final line of defense. The study provides structured guidance to both active workers and construction employees.
