Danger Confined Space No Unauthorised Access Keep Locked Signs help you control entry at hatches, tanks, chambers and service doors by warning people, restricting access and reinforcing lock discipline.
Danger Confined Space No Unauthorised Access Keep Locked Signs combine warning, prohibition and mandatory messages in one clear sign, helping you stop casual entry, guide authorised workers and keep high-risk access points locked at tanks, chambers, ducts and plant areas.
Where Confined Space Access Should Be Controlled
You should install this sign at the direct point of entry, not several metres away, so the warning is seen before anyone reaches a hatch, tank, chamber, duct door or plant access point. Its value is strongest where the physical lock and visual instruction work together.
Practical Viewing Distance for This Confined Space Sign
Use the smaller size where people approach slowly within roughly 3–6 metres, such as plant rooms or internal service doors. Choose the larger format where the sign must be read sooner, around 6–12 metres, near yard entrances, external chambers or busy maintenance routes.
Expected Behaviour Change Around Locked Confined Spaces
This sign helps you turn a locked access point into a clearer control point. Workers, contractors and visitors can see the hazard, understand that entry is restricted and recognise that the space must remain secured unless authorised procedures are in place.
✅ Fewer casual attempts to open confined space doors or hatches
✅ Better reinforcement of permit, lock-off and supervision controls
✅ Clearer instruction for contractors working near restricted plant areas

Better Placement Choices for Locked Confined Space Entrances
❌ Access Control Mistakes to Avoid
❌ Do not place the sign away from the actual entry point where it can be missed.
❌ Do not rely on the sign if the lock, latch or access procedure is unclear.
❌ Do not fit it behind pipework, guards or stored equipment that blocks the message.
❌ When This Sign Is Not Enough
❌ Do not use it as a substitute for a confined space risk assessment.
❌ Do not use it alone where entry requires gas testing, rescue planning or permits.
❌ Do not choose adhesive vinyl for rough, dusty or damp surfaces that may fail.
✅ Stronger Installation Decisions
✅ Mount it at eye level where the person reaching the access point must face it.
✅ Pair it with a physical lock so the instruction is backed by real control.
✅ Use the larger size where vehicles, contractors or yard traffic approach from distance.
Confined Space No Unauthorised Access Keep Locked Sign questions answered
What are Danger Confined Space No Unauthorised Access Keep Locked Signs used for? They warn people that a confined space is present, restrict entry to authorised persons and remind staff that the access point must remain locked.
Where should this sign be positioned? Place it on or immediately beside the access door, hatch, tank entry, chamber cover or plant room entrance so the message is seen before someone can attempt entry.
Is this sign enough to control confined space entry? No. It supports your control system, but it should sit alongside risk assessment, training, supervision, lock control and any permit-to-work procedure required for the task.
Should I choose rigid plastic or self-adhesive vinyl? Use vinyl on clean, smooth indoor surfaces. Choose rigid plastic where the sign needs a more durable fixing on doors, walls, posts or exposed access points.
Why does the sign include three different colours? Each colour separates the safety message: yellow warns of danger, red prohibits unauthorised access and blue gives the mandatory instruction to keep the access point locked.
