OSHA Focus Four - Struck-By Hazards

What is the OSHA Focus Four - Struck-By Hazards?

The OSHA Focus Four — Struck-By Hazards course from the American Institute of Safety Professionals provides in-depth training on preventing the second leading cause of construction fatalities: workers being struck by falling objects, flying debris, swinging loads, and rolling vehicles or equipment. Struck-by incidents account for approximately one in four construction fatalities every year, and they occur on virtually every construction site because materials are lifted overhead, tools and debris can become projectiles, crane loads may swing unexpectedly, and vehicles and heavy equipment routinely operate in areas where workers are present.

OSHA categorises struck-by hazards into four subcategories, and this course covers all four in depth: struck-by falling objects (materials dropped from overhead work, tools falling from scaffolds, structural components dislodged during erection), struck-by flying objects (fragments from power tools, nails from pneumatic nailers, debris from cutting and grinding, objects ejected from rotating equipment), struck-by swinging objects (crane loads, suspended materials, objects on tag lines, and objects swinging from articulated equipment), and struck-by rolling objects (vehicles backing, equipment changing direction, pipes and cylindrical materials rolling on slopes, and equipment rollovers). Each subcategory presents unique hazard mechanisms, regulatory requirements, and prevention strategies that safety professionals and supervisors must understand to protect workers effectively.

The curriculum covers struck-by hazard recognition across all four subcategories, overhead protection requirements (toe boards, debris nets, canopies, and barricading below overhead work), crane and rigging safety awareness for struck-by prevention (load securement, tag line management, and crane swing radius control), construction vehicle and equipment traffic management (designated travel routes, spotters, proximity warning systems, backing alarms, and pedestrian segregation), hard hat requirements and selection, protective eyewear for flying debris, tool tethering and securing, material storage and stacking safety, and the barricading, exclusion zones, and communication systems that separate workers from moving objects and hazardous energy sources.

All training is delivered 100 percent online through Microsoft Teams and the American Institute of Safety Professionals Learning Management System (LMS). Upon successful completion, graduates receive an American Institute of Safety Professionals certificate, professional wallet card, and official transcript, all employer-verifiable at amiosp.com/student-verifications.

Who should take this course?

• Construction workers exposed to overhead work, crane operations, or vehicle traffic on site
• Crane operators, riggers, and signal persons whose operations create struck-by exposure for ground workers
• Equipment operators and truck drivers working on construction sites with pedestrian workers
• Supervisors and foremen responsible for overhead protection, barricading, and traffic management
• Safety officers managing struck-by prevention programmes and PPE compliance
• Anyone working below elevated work platforms, scaffolds, or overhead steel erection
