Warning and No Entry Signs for Strong Magnetic Fields

Magnetic field warning signs mark the entrances to places with strong magnetic fields, such as MRI rooms, laboratories, transformer rooms and high current installations. A strong magnetic field can affect medical devices such as pacemakers, pull metal objects with great force and pose a risk for some implants. The entrance should therefore clearly show both the hazard and who must not enter.

Signs in This Category

• Warning signs: a yellow triangle magnetic field warning sign and a bilingual Turkish English strong magnetic field sign.
• No entry signs: no entry for people with pacemakers, people with prostheses and pregnant women.
• Object restrictions: no entry with watches or metal objects.
• Non-ionizing radiation: a caution sign for electromagnetic field sources.

How to Position the Signs

Place the warning sign and the no entry signs together, above or right next to the door, so they are seen before the door opens. In hospitals and other places with many visitors, bilingual Turkish English signs help foreign patients and companions understand the warning too. Signs are available as vinyl stickers, 3 mm PVC (dekota) boards or galvanized steel plates in sizes from A5 to A2. If your facility needs custom wording or a custom size, Ilgi Trafik can produce signs to order.
