Danger Moving Machinery Signs
Danger Moving Machinery Signs warn staff, contractors and visitors that operating equipment presents a moving machinery hazard. Used on or near machinery and access points, they give an immediate visual warning so people recognise the risk before approaching or working nearby.
Position the warning before the machinery risk
Install the sign on or beside machinery where it can be seen before anyone reaches the hazard area. Keep it in a clear sightline, at a practical viewing height and away from moving parts. Early visibility gives people time to recognise the risk and approach more cautiously.
Choose a size for the approach distance
Choose size by how early the warning needs to be seen, not just by the space available. Use the table as a practical starting point, then go larger where distance, viewing angle, lighting or surrounding equipment makes the message harder to pick out.
| Sign size | Practical starting distance | Best considered when |
|---|---|---|
| H 210 x W 148 mm | Around 2–4 metres | People see the sign at close range |
| H 297 x W 210 mm | Around 4–7 metres | You need earlier recognition on the approach |
| H 420 x W 297 mm | Around 7–10 metres | The warning needs to stand out from farther away |
What should change after the sign is fitted
Placed before the hazard point, the sign gives people a clear cue to recognise moving machinery and change how they approach. It reinforces instructions for operators, contractors and visitors while supporting—not replacing—guarding, isolation and safe working procedures.

Installation Guidance
❌ Mounting the sign where somebody sees it only after reaching the machinery gives them too little time to respond.
❌ Positioning it behind guards, open doors, stored items or equipment can remove the warning from the normal approach sightline.
❌ Choosing the smallest format simply because it fits the available space can make the message ineffective at the actual viewing distance.
❌ Do not use the sign as a substitute for required guarding, interlocks, isolation arrangements or safe working procedures.
❌ Do not rely on a general machinery warning when your risk assessment requires people to understand a more specific trapping, crushing, cutting or entanglement hazard.
❌ Do not rely on this non-reflective, non-photoluminescent product where the warning must remain conspicuous in darkness without suitable illumination.
✅ Position the sign so it enters the normal line of sight before a person reaches the machinery hazard.
✅ Match the fixing method to the chosen material and mounting surface, preparing the surface appropriately when using a self-adhesive option.
✅ Check the finished position from the normal approach direction and keep the sign visible, legible and unobstructed during routine workplace checks.
Frequently asked questions
What is the Danger Moving Machinery Sign used for? You use it to give people an immediate warning that machinery capable of movement presents a hazard nearby, helping them recognise the risk before approaching the equipment.
When should I choose this instead of a more specific machinery hazard sign? Choose this general machine hazard warning when moving machinery is the risk you need to communicate. If you need to identify a particular trapping, crushing, cutting or entanglement hazard, a sign showing that specific risk will give people more precise information.
Which size should I choose? Base your choice on how far away people first need to recognise the warning. The smallest size suits closer viewing, while the larger formats give you more visual presence where the approach distance is greater or the surroundings are visually busy.
Which material option is right for my installation? Start with how you intend to mount it. Vinyl and Adhesive Rigid Plastic have self-adhesive backing, Rigid Plastic requires separate fixing materials, and Removable, Repositionable Vinyl suits locations where you may need to adjust the position.
Can I display the sign outdoors? Indoor and outdoor display are listed for this product. You should still select the material and fixing method appropriate to the particular surface and exposure at your installation point.
Is this sign reflective or photoluminescent? No. The available options are non-reflective and non-photoluminescent, so choose another product if enhanced visibility in darkness or reduced lighting is a requirement.
Does a moving machinery warning sign replace machine guarding? No. Use the sign as part of your risk communication arrangements; it does not replace guarding, isolation, safe systems of work or other controls required by your risk assessment.
Features and Benefits
- ✓ General warning pictogram paired with written moving machinery identification
- ✓ Prominent “Danger” heading creates a clear visual hierarchy
- ✓ Portrait layout keeps the symbol and hazard wording together
- ✓ Choice of permanent and repositionable mounting formats
- ✓ Helps people recognise a machinery risk before they approach the equipment
- ✓ Makes the warning easier to understand when the hazard is not immediately obvious
- ✓ Gives you flexibility to position the message where it is most likely to be seen
- ✓ Reinforces consistent machinery risk communication for staff, contractors and visitors
More specific machinery hazard messages
Where unexpected operation is the greater concern, choose portrait automatic machinery start signs. Their wording gives people more specific information about the nature of the danger.
If the hazard is concentrated at a trapping point, compare pinch point landscape warning signs. A targeted caution can be more useful than a broad machinery warning where the risk is clearly defined.
For equipment where work is being carried out, consider men working on machine warning signs. This message directs attention towards the presence of people working on the machinery.
For a broader comparison, browse our machinery and electrical safety signs. This helps you narrow your choice according to the particular hazard that needs communicating.
