Danger Overhead Hazard Signs
Danger Overhead Hazard Signs warn you, your staff and visitors about head-height risks before they step beneath beams, suspended loads, machinery or work taking place above. Use them where overhead dangers are easy to miss but could cause a serious head injury.
Where Danger Overhead Hazard Signs Should Be Displayed
You should install these signs at entrances to low-clearance routes, beneath mezzanines, near loading doors, around scaffolding, workshops and plant rooms. Put the sign before the hazard, not on top of it, so people can slow down, look up and choose a safer route.
Practical Viewing Distance for Overhead Hazard Warnings
For A5 signs, use close-range points up to around 2–3 metres. A4 suits everyday walkways and door approaches around 4–6 metres. Choose A3 or A2 where people approach faster, carry goods or need the warning visible across wider work areas.
What Should Improve Once This Warning Is Installed
Once fitted in the right place, this sign helps people pause before moving under overhead risks. It gives a clear early warning, supports safer route choices and reminds staff not to ignore areas where head injury risks may not be obvious at first glance.
