Print tips
- Print at "actual size" or 100%, not "fit to page", so the margins stay even.
- Use thicker paper or card (160gsm or more) if the sign will be handled.
- For outdoor or long-term use, laminate it or buy a rigid version.
Where to use it
- Corridors, stairwells and doorways where repairs are under way
- Under scaffolds, ladders and roof work
- Plant rooms, switchboards and equipment being repaired
- Shops and offices during refits
- A-frames and free-standing boards at the edge of a work area
Questions
Can I use these on a public road or pavement?
No. Roadworks have their own regulated signs and rules. These are for private land and inside buildings.
Should I say men at work or people at work?
Either works as a warning. Use people at work if your team is mixed or you prefer neutral wording.
Is the do not switch on sign enough to isolate equipment?
No. A sign is a reminder, not safe isolation. Equipment should be properly isolated and secured by someone competent as well.
What size should I use?
A4 on doors and barriers, A3 where people approach from a distance.
