Do Not Use Out Of Order prohibition signs clearly stop staff, contractors and visitors using faulty equipment, machines or facilities. Use them on doors, appliances, plant and workplace items to reduce confusion, prevent unsafe operation and support controlled repairs.

Where Do Not Use Out Of Order Signs Should Be Placed

You should install these signs directly on or beside the item that must not be used, such as machinery, appliances, washroom facilities, doors, tools or plant. The sign needs to sit at eye level where the user makes the decision, not hidden nearby.

Viewing Distance Guide for Choosing the Right Size

Choose the smaller size for close-up decisions at around 1–3 metres, such as switches, equipment doors and appliances. Use the larger size where people approach from a corridor, workshop floor or open facility area at roughly 3–6 metres.

Size option	Practical viewing use
H 100 x W 250 mm	Close-range equipment, doors, small plant and appliances
H 150 x W 300 mm	Workshop approaches, shared facilities, larger machines and corridor-facing points

What Improves Once the Sign Is in Place

Once fitted, the sign gives people a clear stop point before they use an unsafe item. It helps maintenance teams control access, reduces casual “quick use” decisions and makes faults easier to manage while repairs or checks are arranged.

✅ Fewer people attempt to use faulty equipment before repair

✅ Staff and visitors understand the item is unavailable immediately
