Shipyard Hazard Recognition and OSHA 10 Construction Safety

Why Hazard Recognition Matters in a Shipyard

Shipyards are among the most hazardous industrial workplaces in the United States. Workers share tight spaces with overhead cranes, high-voltage equipment, open hull sections, and miles of piping—all at the same time. OSHA regulates most shipyard employment work under 29 CFR Part 1915 (Shipyard Employment) and general construction activities under 29 CFR Part 1926 (Construction Industry). The OSHA 10-Hour Construction Safety outreach course gives you a common vocabulary for talking about hazards, but you must also know where the shipyard-specific rules sit.

The single most useful organizing tool OSHA provides is the Focus Four—four categories that account for the overwhelming majority of construction and marine fabrication fatalities. Every hazard you encounter on the job can be sorted into one of these four buckets, and knowing the bucket tells you which controls to reach for first.

The Focus Four Hazards

1. Falls

Falls are the leading cause of death in construction and a constant threat in shipyards where workers climb staging, work on tank tops, or move between levels of a vessel under construction. The primary standard for construction fall protection is 29 CFR 1926 Subpart M, which requires fall protection when workers are at or above six feet over a lower level. On vessels, that threshold can be reached the moment you step onto a staging plank over an open bilge.

Common shipyard fall hazards include: unguarded deck openings (manholes, access hatches), staging without toe boards or guardrails, and slippery surfaces from oil, water, or weld spatter. Controls follow the hierarchy—elimination, substitution, engineering controls (guardrails, covers), administrative controls (warning lines, signage), and PPE (personal fall arrest systems). Never rely on PPE alone; it is the last line of defense.

2. Struck-By

A struck-by event occurs when a worker is hit by a moving object—a crane load, a rigging sling, a dropped tool from overhead staging, or a vehicle moving through a yard. In shipyards, overhead crane picks happen constantly. The rule: never stand under a suspended load. Hard hats (ANSI Z89.1 Class E for electrical environments) are mandatory. High-visibility vests are required wherever vehicles operate.

Key controls: tag lines to control swinging loads, exclusion zones under lifts, proper rigging inspection before every lift, and housekeeping—loose items left on staging become projectiles.

3. Caught-In/Between

This category covers incidents where a worker is caught, compressed, crushed, or pinched by machinery, equipment, or collapsing material. In a shipyard this means: rotating grinder wheels, unguarded rollers on a plate roll, workers caught between a vessel hull and the drydock wall during a docking evolution, or a trench/cavity collapse if shore-side earthwork is involved.

Machine guarding requirements under 29 CFR 1926 Subpart I (Tools—Hand and Power) require that all moving parts that could contact a worker be guarded. Angle grinders must have the wheel guard in place—removing it is a serious violation and a common near-miss scenario in fabrication shops.

4. Electrocution

Shipyard environments are particularly dangerous electrically because metal hulls and wet bilges create excellent ground paths. Electrocution hazards include: temporary power distribution systems (spider boxes) with damaged cords, welding leads with failed insulation, and working near energized bus bars or ship's service electrical panels.

Ground Fault Circuit Interrupters (GFCIs) are required on all temporary power in construction environments. Welding machines must be properly grounded. Always assume a circuit is live until you have personally verified it is de-energized through a lockout/tagout procedure.

Lockout/Tagout (LOTO) in the Shipyard

Lockout/Tagout is governed by 29 CFR 1910.147 (OSHA's Control of Hazardous Energy standard, which applies to general industry and is referenced for shipyard employment). The purpose: prevent the unexpected energization or startup of machinery while a worker is servicing or in the energy path of that equipment.

Two roles matter most:

• Authorized Employee – the person who performs the lockout. This person applies the lock.
• Affected Employee – anyone who operates the equipment or works in the area. They must be notified before and after the lockout.

The essential LOTO sequence (simplified):

1. Notify affected employees.

2. Identify all energy sources (electrical, pneumatic, hydraulic, stored/gravity).

3. Shut down the equipment using normal stopping procedures.

4. Isolate the energy source (open the disconnect, close the valve).

5. Apply lockout device and lock; attach a tag.

6. Release or restrain stored energy (bleed pneumatic lines, block gravity loads).

7. Verify zero energy state—attempt to start the equipment, test with a meter.

8. Perform the work.

9. Remove tools and materials; replace guards.

10. Remove lock, notify affected employees, restore energy.

Every critical step must be completed in order. Skipping verification (step 7) is the most common fatal error.

PPE Baseline for Shipyard Work

Before entering any shipyard work area, confirm you have: hard hat, safety glasses (ANSI Z87.1), hearing protection where noise levels require it, steel-toed boots (ASTM F2413), and gloves appropriate to the task. Add a full-face shield for grinding, a welding helmet with correct shade for your process, and a personal fall arrest system (PFAS) whenever you work at height without a guardrail system.
