Danger Construction Work In Progress Signs
Danger Construction Work In Progress Signs give you one clear site entrance message for active building areas. They help contractors, visitors and delivery drivers understand access rules, smoking restrictions and reception reporting before moving further into risk areas.
Where Danger Construction Work In Progress Signs Should Be Installed
You should install this sign at site entrances, temporary fencing, gate approaches, reception routes and contractor access points where people must stop, read the rules and understand that construction work, restricted access and smoking controls apply before entry.

Choose the size around how early people need to react. Smaller signs suit close pedestrian entry points, while larger formats work better on hoarding, perimeter fencing and vehicle approaches where reading distance matters.

|---|---|---|
| H 400 x W 300 mm | Pedestrian gates and doors | Up to 5 metres |
| H 600 x W 450 mm | Main site entrances | Up to 8 metres |
| H 800 x W 600 mm | Hoarding and wider access points | Up to 12 metres |

Connected signs for live construction work areas
For demolition-specific activity, use demolition work in progress signs where dismantling or debris makes the risk more severe. They help you avoid using a general works message where a clearer warning is needed.
Where workers are exposed around the work area, add reflective caution men at work signs near temporary routes or lower-light locations. This supports visibility when tasks move around site.
If the site boundary also needs control, compare with danger keep out construction signage for fencing and entrances. It helps stop access before people reach active works.
For overhead work risks linked to construction, choose danger falling objects signs where tools, materials or debris could drop. This gives a more precise warning than a general work notice.
For a wider set of active works warnings, explore site safety hazard signs for works and choose messages that match your task, route and access risks. This keeps the site easier to understand.
