Danger Acid Signs
Danger Acid Signs warn you, your staff and visitors that corrosive acids are present and extra care is needed. Used in laboratories, chemical cupboards, workshops and storage rooms, they help reduce contact risk, eye injury, burns and unsafe handling.
Where Danger Acid Signs Should Be Installed
You should install Danger Acid Signs at eye level near acid storage cupboards, laboratory benches, dosing equipment, battery rooms, chemical cabinets and access doors so people see the risk before opening, handling or entering.
Practical Viewing Distance for Acid Warning Signs
Choose the size around how early people need to react. Small cabinet signs work close up, while larger door or wall signs suit corridors, stores and plant rooms where warning needs to be read before approach.
| Sign size | Best viewing distance | Typical use |
|---|---|---|
| H150 x W125 mm | 1–2 metres | Cupboards, cabinets, small doors |
| H297 x W210 mm | 3–5 metres | Lab entrances, stores, workshops |
| H594 x W420 mm | 7–10 metres | Large rooms, plant access, shared routes |
What Should Improve Once the Sign Is Fitted
Once fitted in the right place, this sign helps people slow down, check what they are handling and treat acid storage or use points as controlled-risk areas rather than ordinary cupboards, doors or workstations.

Danger Acid Signs questions answered
What are Danger Acid Signs used for? They are used to warn people that acid is present and that contact, splashes or unsafe handling could cause burns, eye injury or material damage.
Where should I fit an acid warning sign? Fit it where people make a decision: on chemical cupboard doors, lab entrances, acid storage shelves, dosing areas, battery rooms or maintenance access points.
Is this the same as a corrosive substance sign? It uses the corrosive substance pictogram, but the wording “Danger Acid” gives a more specific warning where acids are the known hazard.
Should I choose rigid plastic or self-adhesive vinyl? Use vinyl for smooth indoor doors, cupboards and cabinets. Choose rigid plastic where you need a more durable wall-mounted sign or a surface is less suitable for adhesive.
Does the sign help with safety compliance? Yes, when correctly used, it supports workplace hazard communication by using the recognised EN ISO 7010 W023 symbol and BS 5499-style safety sign format.
