About This Course

Every year, a staggering majority of workplace injuries and fatalities are attributed to four highly preventable hazard categories. Known as OSHA's "Big Four"—falls, electrical exposures, struck-by incidents, and caught-in or between hazards—these risks represent the most critical dangers present on industrial and construction sites today.

This comprehensive course provides an in-depth examination of these leading causes of workplace accidents, exploring the underlying conditions and daily operational risks that make them so deadly. The training delves into practical hazard recognition strategies, essential safety protocols, and key OSHA standards designed specifically to mitigate these top-tier risks.

By examining real-world scenarios, preventative measures, and industry best practices, this foundational safety guide delivers the crucial awareness needed to foster a proactive culture of safety, significantly reduce job site incidents, and ensure that every worker returns home safely at the end of the day.
