Danger Confined Space Entry By Permit Only Sign helps you control authorised access around tanks, chambers, ducts and service voids, reducing unauthorised entry risk.
Danger Confined Space Entry By Permit Only Sign warns that a restricted space must not be entered without formal authorisation. It helps site managers, contractors and maintenance teams control access around tanks, chambers, ducts and voids where serious hazards may exist.
Where Confined Space Permit Signs Should Be Positioned
You should install this sign at the point where a person makes the decision to enter, such as tank hatches, chamber covers, duct openings, service voids and plant access doors. It needs to be seen before tools, ladders or entry equipment are used.
Practical Viewing Distance Guidance
Use smaller sizes for close approach points within 1–3 metres. Choose A3, A2 or A1 where the sign must be read across yards, plant rooms, service corridors or outdoor work areas before workers reach the confined space entry point.
Behaviour Changes You Should See Around Confined Space Entry
This sign helps turn a dangerous access point into a controlled decision point. Workers, contractors and visitors are reminded that entry is not a casual task and must be managed through your permit process.
✅ Fewer unauthorised attempts to enter restricted spaces
✅ Stronger permit-to-work checks before access begins
✅ Clearer separation between trained entrants and others

Fitting Advice for Confined Space Permit Control Points
Entry Point Mistakes To Avoid
❌ Placing the sign inside the confined space where it is seen too late
❌ Fitting it behind pipes, handles or stored equipment
❌ Using a small size where workers approach from several metres away
When This Sign Is Not Enough
❌ Do not rely on signage alone where atmosphere testing is required
❌ Do not use it as a substitute for training, permits or rescue planning
❌ Do not place it on dirty or damaged surfaces that reduce adhesion
Better Permit-Control Placement
✅ Position it before the hatch, cover or door is opened
✅ Match the size to the approach distance and lighting conditions
✅ Check visibility during inspections, shutdowns and contractor work
Danger Confined Space Entry By Permit Only Sign questions answered
What is a Danger Confined Space Entry By Permit Only Sign? It is a safety sign used to warn that a confined space presents serious risk and must only be entered under your permit-to-work procedure.
Where should you place this sign? Fit it directly at the access point, such as a hatch, chamber, tank opening, duct entry, silo access or plant room door where workers may approach.
Does this sign replace a confined space permit? No. It supports your permit system by making the restriction visible, but you still need proper assessment, authorisation, supervision and rescue arrangements.
Which material should you choose? Use self-adhesive vinyl for clean, smooth surfaces. Choose rigid plastic where you need a more durable sign fixed to doors, walls or external access points.
Why does the sign include both warning and prohibition colours? The yellow warning section identifies the confined space hazard, while the red section makes it clear that entry is restricted to authorised permit holders.
