Lesson: Conduct continuous monitoring of soil conditions during drilling, using geotechnical data to install shoring or casing as needed. Expanding this to include real-time communication with a competent person on site ensures early detection of belling or sloughing, preventing entombment and allowing for immediate evacuation protocols.

Pile Driving Worker Crushed by Hydraulic Tool (2019)

During pile driving, an employee was caught by hydraulic equipment and sustained fatal head injuries. Guarding and procedures were inadequate.

Lesson: Install machine guards on all moving parts and enforce lockout/tagout during maintenance or adjustments. Expanding training to include hands-on simulations helps workers recognize pinch points early, fostering a safer workflow in the intense environment of pile installation.

Geotechnical Worker Struck by Motor Grader During Soil Testing (2011)

An employee performing compactness tests on an active site was backed over by a motor grader due to lacking traffic controls and high-visibility gear, violating 29 CFR 1926.200.

Lesson: Establish dedicated exclusion zones around testing areas with barriers and require high-visibility clothing for all personnel. Additionally, assign spotters or use backup alarms on vehicles to enhance awareness—turning potential blind-spot accidents into preventable near-misses through layered safety measures.

Barge Worker Falls into Water and Drowns (2019)

A deckhand on a barge during marine construction (bridge work support) fell overboard without a life jacket or fall protection. No rescue boat was immediately available. OSHA cited violations of 29 CFR 1926.106 (working over water) and maritime standards.

Lesson: Require mandatory PFDs (personal flotation devices) for all over-water work, maintain readily available rescue boats/equipment, and conduct regular drills—critical for preventing drownings in marine environments.

Crane Operator Struck by Swinging Load on Floating Platform (2020)

During marine pile-related support work on a barge, a swinging crane load struck and killed an operator due to unstable deck conditions and no tag lines or load control. Violations included inadequate stability and rigging under 29 CFR 1926.1401 and maritime rules.

Lesson: Use tag lines and dedicated signal persons to control swinging loads on unstable platforms. Perform pre-lift stability assessments on barges to avoid struck-by fatalities.

Diver Injured by Underwater Debris During Marine Salvage/Construction (2022)

A commercial diver performing underwater inspections/repairs near a marine structure was struck by shifting debris or equipment, suffering serious injuries. OSHA noted failures in hazard communication, dive team coordination, and protective barriers (violating 29 CFR 1910 Subpart T – Commercial Diving).

Lesson: Establish clear dive plans with surface support, use exclusion zones for overhead hazards, and ensure constant tender communication—essential for safer underwater marine operations.

Pile Driver Operator Falls from Equipment (2013)

An employee standing on the tracks of a pile driver at a construction site fell and sustained fatal injuries. No fall protection was in place.

Lesson: Mandate the use of harnesses, guardrails, or platforms on elevated equipment like pile drivers—with regular training on their proper application. This approach not only complies with fall protection standards but also builds worker confidence, reducing hesitation in dynamic environments where slips are common.

Sheet Pile Falls and Strikes Worker (2015)

During operations, a sheet pile broke free from the hammer and fell—striking and killing an employee in the back, neck, and head. Improper securing was cited.

Lesson: Ensure all piles are securely attached with redundant fastening methods before hammering begins and clear the area of non-essential personnel. By incorporating daily equipment checklists and exclusion zones, teams can mitigate falling object risks—preserving focus on precision work without constant fear of overhead hazards.

Foundation Drill Rig Overturns and Buries Operator (2018)

An operator fell from a foundation drill rig, then was suffocated under collapsing soil. No fall protection or stability assessments were performed, violating 29 CFR 1926.501.

Lesson: Require harness systems and guardrails on rigs, combined with daily soil stability evaluations by a qualified geotechnical expert. This dual focus on personal protection and site conditions prevents overturns and burials, enabling safer repositioning and operation in variable terrains common to deep foundation work.

Trench Collapse in Deep Foundation Preparation (2019)

An employee was working in a nine-foot-deep trench installing pipe when the walls collapsed, burying and killing them. No shoring or sloping was used.
