Container Lashing at Height
At a marine terminal, longshore workers are lashing and unlashing containers stacked four high on a vessel's deck. The top of the fourth tier is about 34 feet above the dock. Workers climb a portable ladder attached to the container stack and walk along the tops of containers to attach lashing rods. There is no guardrail, safety net, or personal fall arrest system. The terminal's supervisor says fall protection is required only above 4 feet in general industry and that lashing is 'stevedoring,' so the 6-foot construction rule does not apply. A worker suggests tying off to the container corner casting with a 3/8-inch synthetic rope and a body belt. Wind is gusting to 20 mph, and the deck is wet.
1. What fall protection requirements apply, and is the supervisor's reasoning correct?
Read the worked answer
The supervisor's reasoning is wrong. The work is longshoring/marine terminal work, so the maritime standards apply, not the general-industry 4-foot or construction 6-foot thresholds. At 34 feet above the dock, with workers walking on container tops, fall protection is clearly required. The employer must provide guardrails, safety nets, or a personal fall arrest system, and must ensure the walking/working surface and access are safe. The portable ladder attached to the stack may not be a safe access; container tops are not designed as walking surfaces and may be slippery when wet. Wind at 20 mph increases the risk. The employer should stop the lashing work until a fall protection system is in place, workers are trained, and a rescue plan exists. This is not a close call about height; it is a clear fall hazard.
2. Evaluate the proposed tie-off to the container corner casting with rope and body belt.
Read the worked answer
The proposed tie-off is unacceptable. Body belts are not permitted for fall arrest because they can cause serious injury; a full-body harness is required. A 3/8-inch synthetic rope is not a rated fall arrest lanyard, and the container corner casting is not a certified anchorage unless a competent person verifies it can withstand the required load. Fall arrest anchorage generally must support 5,000 pounds per worker or be designed with a safety factor by a qualified person. The system also needs a shock-absorbing lanyard or self-retracting lifeline and a rescue plan for a worker left suspended. The wet deck and 20-mph wind make the work more hazardous. The employer should provide engineered anchorage points, inspected harnesses and lanyards, and training, or use an elevated work platform/guardrail system instead.
3. What should the employer do before work resumes?
Read the worked answer
Before work resumes, the employer should stop the job, barricade the area, and conduct a hazard assessment with a competent person. The assessment should cover access to the container tops, the fall protection method, anchorage, wind limits, wet surfaces, and rescue. The employer should provide the selected system, train workers on inspection and use, and ensure someone can rescue a suspended worker promptly. The portable ladder should be replaced or secured; container-top walking should be minimized. Supervisors should be retrained so they do not rely on the wrong height threshold. The employer should document the changes and monitor weather. If the vessel's schedule pressures workers to continue, the employer must still stop until controls are in place; production does not override a recognized fall hazard.
