Course Overview
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.
Learning Outcomes
Upon completing the participants will be able to:
- Classify struck-by hazards into the four OSHA subcategories: falling objects, flying objects, swinging objects, and rolling objects, understanding the distinct hazard mechanisms and prevention strategies for each category.
- Identify falling object hazards: overhead work dropping tools and materials, scaffold work without toe boards, structural members falling during erection, and improperly secured hoisted materials.
- Implement falling object protection: toe boards on scaffolds and elevated platforms, debris nets and screening beneath overhead work areas, canopy structures for pedestrian protection, secured tool lanyards, and barricading of drop zones.
- Identify flying object hazards: debris from concrete cutting, grinding, chipping, and sawing operations; nail ejection from pneumatic tools; projectiles from rotating equipment; and high-velocity fragment trajectories.
- Implement flying object protection: machine guards for abrasive and cutting tools, protective barriers and blast shields, eye and face protection compliant with ANSI Z87.1, and exclusion zones around high-velocity operations.
- Identify swinging object hazards: crane loads during lifting and placement, suspended loads controlled with tag lines, articulated equipment booms, and pendulum motion hazards within swing radius zones.
- Implement swinging load protection: coordinated crane operator/rigger/signal person communication, tag line control procedures, swing radius barricading, and load movement communication protocols.
- Identify rolling object hazards: vehicle backing operations, equipment directional changes, cylindrical materials rolling on slopes, and equipment rollover incidents affecting ground personnel.
- Implement vehicle and equipment traffic management: designated travel routes, speed controls, spotter-assisted backing, proximity detection systems, pedestrian segregation, and formal traffic management plans.
- Select and mandate appropriate PPE for struck-by protection: hard hats compliant with ANSI Z89.1 Type I/II and Class E/G/C, protective eyewear per ANSI Z87.1, face shields, high-visibility apparel, and hazard-based PPE selection.
