Subpart F
Under 1917.113, you must prominently post the clearance height where the height is insufficient for vehicles and equipment. This means the employer must place legible signs or markings in locations where drivers and equipment operators will see them before entering or passing under a low overhead area.
Under 1917.113, clearance heights must be posted in a prominent place where the height is insufficient for vehicles and equipment — typically at approaches, entrances, and any locations where drivers must decide whether to proceed under an overhead obstruction.
Under 1917.113, a clearance is "insufficient" when the available overhead height could prevent safe passage of the vehicles or equipment used at that location — in other words, when vehicle or equipment height approaches or exceeds the overhead clearance.
Under 1917.113, the employer at the marine terminal is responsible for posting clearance heights where the height is insufficient for vehicles and equipment and for keeping those postings visible and in good condition.
Under 1917.113, the posting requirement applies where Part 1917 is applicable. However, Part 1917 generally does not apply to facilities that are "designated waterfront facilities" used solely for bulk storage, handling, and transfer of liquids or gases; those facilities are excluded from Part 1917 per the applicability LOI.
Under 1917.113, the rule requires clearance heights to be "prominently posted" but does not specify exact sign dimensions, colors, or wording. That means signs must be large, legible, and conspicuous enough to warn vehicle and equipment operators in time to avoid the hazard.
Under 1917.113, yes — you must keep postings accurate and prominently posted, so if equipment heights, routes, or overhead structures change, you should promptly update or relocate signs to reflect the new clearance conditions.
Under 1917.113, clearance heights must be prominently posted where the height is insufficient; vehicle-mounted sensors or alarms can be used as additional protective measures but do not remove the obligation to post the clearance height.
Under 1917.113, any situation where the available height is insufficient for vehicles and equipment should have the clearance prominently posted. If temporary stacking or cargo reduces clearance, employers should post warning signs, use physical barriers, or reroute traffic while the condition exists.
Under 1917.113, consider any vehicle or equipment that uses the area: forklifts, top loaders, reach stackers, container handlers, tractors, trailers, truck cranes, and any loads or attachments that increase overall height.
Under 1917.113, postings must be prominent; when operations occur at night or in low light, employers should provide illumination or reflective materials so signs remain visible and effective.
Under 1917.113, if a clearance is close to the height of vehicles or attachments, you should post the clearance height so operators can make an informed decision; when the margin is small, take additional controls such as route restrictions, spotters, or protective barriers.
Under 1917.113, the rule requires that clearance heights be prominently posted; painted height markers on overhead members or columns are acceptable as long as they are prominent, legible, and placed where vehicle operators will readily see them.
Under 1917.113, the standard does not prescribe the units to use, so including both imperial (feet/inches) and metric (meters/centimeters) on the same sign is acceptable and often helpful for mixed fleets or international drivers.
Under 1917.113, you should ensure that the work area has prominently posted clearances and communicate clearance limits to contractors; if contractors bring taller equipment that cannot safely pass, provide alternate routes, restrict access, or post temporary warnings.
Under 1917.113, enforcement depends on whether Part 1917 applies to the facility. If a facility is a "designated waterfront facility" used only for bulk liquids or gases, Part 1917 does not apply per OSHA's applicability LOI, and 1917.113 would not be enforced at that site; otherwise, employers are subject to 1917.113 and could be cited for failure to post required clearances.
Under 1917.113, yes — prominently posted clearances should be integrated into operator training and site safety orientations so drivers and equipment operators know how to identify and respond to clearance warnings.
Under 1917.113, no — the standard requires clearance heights to be prominently posted where height is insufficient; relying solely on personal familiarity does not meet the posting requirement.
