Low Clearance Signs

OSHA requires overhead clearance warnings wherever head hazards exist below the standard safe headroom height of 6 feet 8 inches per OSHA 1910.28, and our low clearance signs help facilities meet this requirement by clearly marking low overhead obstructions before workers or vehicles encounter them.

For parking garage entrances a larger sign typically 18x24 or 24x30 inches ensures the clearance height is visible to drivers well before they reach the obstruction, and our low clearance signs range from small wall labels up to large overhead span signs so you can select the right dimension for the viewing distance and vehicle traffic speed at your specific entrance.

Yes, our customizable templates from our low clearance signs collection allow you to specify the exact clearance height in feet and inches, and our low clearance sign with a clear pre-printed height measurement is more effective than a generic warning because it allows drivers to make an immediate pass/fail decision before approaching the obstruction.

Yes, our bi-directional watch your head sign and projecting options from our low clearance signs collection mount above a doorframe or corridor and extend perpendicular to the wall, making the warning visible from both directions, ideal for tight warehouse aisles, mezzanine underpass areas, and corridors where a wall-mounted sign may not be visible from all approach angles.
