Do Not Switch On signs help maintenance teams, electricians and site staff prevent unsafe re-energising of machinery, controls and isolators during repair or shutdown work.
Do Not Switch On signs tell staff, contractors and visitors that a switch, machine or control must remain isolated. Use them beside isolators, electrical controls, plant rooms and machinery during servicing to reduce accidental start-up risks and protect anyone working nearby.
Where Do Not Switch On Signs Should Be Installed
You should install these signs directly beside isolator switches, control buttons, plant room equipment, machine controls and maintenance access points so the instruction is seen before anyone can energise equipment or interrupt safe working.
Viewing Distance Guidance for Safe Placement
Choose a size that matches how close people will be when approaching the switch or control. Use larger signs where staff view the message from across a room, corridor or machinery access route.
| Size option | Best practical viewing range | Typical use |
|---|---|---|
| H 210 x W 148 mm | Up to 4 metres | Close-up switches and small controls |
| H 297 x W 210 mm | 4–7 metres | Plant rooms and workshop controls |
| H 420 x W 297 mm | 7–10 metres | Larger machinery areas and shared workspaces |
What Changes After the Sign Is Installed
Once installed, the sign gives people a clear pause point before touching controls, helping maintenance teams keep equipment isolated and reducing the chance of someone restarting machinery while work is still taking place.
✅ Helps prevent accidental re-energising during service work
✅ Gives contractors a clear instruction before using controls
✅ Supports safer behaviour around isolators and machinery
