Struck-By Hazards in Construction: OSHA Worker Rights
Learn how OSHA construction guidance addresses vehicle, falling-object, and flying-object struck-by hazards, safety reporting, and retaliation deadlines.
Struck-By Hazards Are Broader Than a Vehicle Crash
OSHA identifies construction struck-by hazards from moving vehicles and equipment, falling or flying objects, and some masonry work. A backing truck, swing radius, suspended load, falling tool, unsecured material, or flying particle can involve different tasks and standards. The jobsite, equipment, work zone, work method, and assigned task matter; an injury or near miss alone does not decide whether a rule was violated or an employment claim exists.
Vehicle and Equipment Zones Need a Site-Specific Plan
OSHA's construction guidance addresses visibility, backing, traffic control, equipment condition, and keeping people clear of moving equipment and lifting or dumping operations. A vehicle with an obstructed rear view generally needs an audible reverse alarm or a worker to signal that backing is safe. The appropriate route, spotter, barrier, signal, or high-visibility clothing depends on the site and task. Do not enter a blind spot, swing radius, roadway, or restricted equipment area to test or document a concern.
Falling and Flying Objects Can Require Different Safeguards
OSHA's construction materials describe risks below cranes, scaffolds, overhead work, and material storage, as well as hazards created by tools and airborne particles. Examples of controls in OSHA materials include securing materials, guarding lower areas, and using measures such as toeboards, screens, debris nets, catch platforms, or canopies where the applicable standard calls for them. Head, eye, and face protection can also depend on the hazard assessment and task. A hard hat or warning sign alone does not establish that every falling-object risk has been addressed.
Related Standards May Still Apply
A struck-by concern can overlap with a separate rule for cranes, scaffolds, motor vehicles, hand and power tools, eye and face protection, materials storage, demolition, or work-zone signs and signals. This page does not determine which standard controls a specific operation or tell a worker to change a site plan. Identify the equipment, load, travel path, work area, task, people exposed, and available safeguards when raising a concern.
Keep a Factual Record Without Creating More Risk
When safe and lawful, preserve the work date and location, assigned task, equipment or material involved, travel path or work zone, training and inspection information available to you, people notified, messages, witness names, and employer response. Keep only records and photographs you may lawfully access. Do not move equipment, stand under a suspended load, remove a barrier, handle a tool, or remain in a hazardous area to gather evidence. Follow the site emergency procedure for an imminent danger or injury.
A Safety Complaint and a Retaliation Complaint Are Different
A safety complaint asks OSHA to assess a hazardous condition or possible standards violation. A Section 11(c) retaliation complaint asks OSHA to assess whether an adverse action followed protected safety activity. Reporting a backing, traffic-control, equipment, falling-material, load, tool, or training concern can be relevant protected activity, but a hazard, report, or injury does not automatically prove retaliation. One filing should not be assumed to complete the other.
The Federal Retaliation Deadline Can Be 30 Days
A federal Section 11(c) retaliation complaint generally must be filed with OSHA within 30 days after the alleged adverse action. Timing, what was reported, employer knowledge, stated reasons, policy history, and treatment of comparable workers can matter. State-plan, workers' compensation, disability, wage, union, contract, and other rights can use different agencies, coverage rules, remedies, and deadlines.
