Confined Space No Unauthorised Access Keep Locked Signs help you control doors, hatches and service entries by warning staff and contractors before unsafe entry.
Confined Space No Unauthorised Access Keep Locked Signs warn you about confined space danger, stop unauthorised entry and remind staff to keep access locked. They suit plant rooms, tanks, ducts, chambers and restricted doors where entry control must be clear before anyone approaches.
Where Confined Space Keep Locked Signs Should Be Displayed
You should install this sign directly on or beside locked confined space doors, hatch covers, tank access points, service chambers and maintenance entries. Put it where the decision to enter is made, so the warning, access restriction and locking instruction are seen before anyone touches the entry point.
Practical Viewing Distance Before Entry
For A4 signs, aim for clear reading at around 2–4 metres near doors, cupboards and hatches. Choose A2 where people approach from longer corridors, yards or plant-room walkways, giving the message more time to stop unsafe access before the lock or handle is reached.
What This Sign Helps Change On Site
This sign helps you turn a locked confined space entry into a clear control point. Staff, contractors and visitors can see the hazard, understand access is restricted and recognise that the entry must stay locked unless a competent person authorises work.
✅ Fewer casual attempts to open confined space doors or hatches without permission
✅ Stronger contractor understanding that locked access is part of the control system
✅ Clearer separation between general site movement and controlled confined space entry

Installing Confined Space Keep Locked Signs Without Weakening The Message
❌ Placement mistakes that reduce control
❌ Fitting the sign away from the actual hatch, door or access point
❌ Mounting it too low where equipment, bins or stored materials can hide it
❌ Using a small size where people approach from a long corridor or yard
❌ Situations where this sign is not enough
❌ Do not rely on it alone for live entry, rescue or atmospheric testing controls
❌ Do not use vinyl on dusty, wet or rough surfaces where adhesion may fail
❌ Do not treat it as a substitute for locks, permits, training or supervision
✅ Better fitting choices for restricted access
✅ Place it at eye level beside the handle, lock, hatch or approach route
✅ Use A2 where approach distance, poor lighting or outdoor visibility needs stronger impact
✅ Check after installation that the sign remains readable when the door is open or closed
Confined Space No Access Keep Locked Signs questions answered
What are Confined Space No Unauthorised Access Keep Locked Signs used for? They warn you that a confined space is present, restrict entry to authorised people and reinforce that the access point must stay locked when not under control.
Should I choose this sign instead of a permit-to-work sign? Use this version when the main control is locked access and restricted entry. Choose a permit-to-work message where entry must only happen after a formal permit is issued.
Where should this sign be placed for best effect? Put it on the door, hatch, gate or immediate approach to the confined space so the message is seen before someone can open or unlock the entry point.
Is rigid plastic or self-adhesive vinyl better? Rigid plastic suits long-term wall, door or outdoor fixing. Self-adhesive vinyl works best on smooth, clean internal surfaces where drilling is not suitable.
Does this sign replace a confined space risk assessment? No. It supports your control measures, but you still need suitable assessment, access control, supervision, training and emergency arrangements for confined space work.
