Overhead Hazard Signs
Overhead hazard signs go under crane runs, at the ends of high pallet racks and beneath pipes or ductwork that hang low over walkways. Plant managers, warehouse supervisors and shop owners use them to warn people walking below that something overhead can strike them.

Where overhead hazard signs are used
Scaffold erectors, sign crews and building maintenance teams post this sign on the underside of a canopy, at the mouth of an elevator shaft, and on a stanchion where a lift platform swings above a walkway. A retail store may hang one beside a rolling ladder that reaches a high shelf, and a gym places one under a hanging basketball backboard. The sign says that something above can strike a person below, so people look up before they walk beneath.
Choosing the size and where to hang it
On a column or wall beside the overhead hazard, mount it at about eye level, so a walker sees it before reaching the spot beneath. The 36 in x 24 in size works for a long canopy edge, and the 18 in x 12 in size suits a single column. Aluminum is the choice for a ceiling spot outdoors or in a damp building, and its holes take screws into a steel post. Plastic is light and works indoors on a column, fastened with tape or grommets and zip ties.
Questions about overhead hazard signs
Where should I hang an overhead hazard sign?
Hang it on the hazard itself or on a post at the walking path, where a person can see it before passing under. Place a sign at each entry to the area so people see it from both directions. Your safety officer sets any height or clearance rules for your building.
Caution or Danger for overhead hazards?
The right header depends on what could fall or swing. Ask your safety officer whether the hazard could cause minor or moderate injury, which points to Caution, or death or serious injury, which points to Danger.
Which material suits a ceiling spot?
Plastic is light at .020 in and flexible, printed on one side with brass grommets for hanging. Aluminum is .040 in, rust-free and printed on one or two sides, with 1/4 in holes at the corners or top for mounting.
Can the sign go on the hazard itself?
Mount it beside the hazard or on the post that leads to it, not on a pipe that moves or a rack that gets loaded. The sign states the warning, but it does not make the pipe safer. A pipe or crane run that hangs too low needs a fix from your facilities team, and check your state and local rules for the clearance and crane signs that apply.
What if the hazard changes height?
Some overhead items move, such as a hoist or a lift. Use the optional extra line for the area or equipment name, like 'Crane bay 2', so the sign stays tied to the spot. Re-check the sign whenever the layout changes, and keep it clear of the moving parts.
