Do Not Enter - Flashing Light Signs

Our warning light flashing do not enter sign is used at x-ray rooms, CT and MRI suites, laser labs, radiation treatment rooms, automated robotic cells, noise-isolated testing chambers, and any area where a warning light system indicates an active hazard, communicating to all personnel that the flashing light is a functional safety system and that entry during active flashing is prohibited.

Yes, our customizable templates from our flashing light signs collection allow you to add the specific reason for the light restriction, safe entry procedures, who to contact before entering, or the type of hazard present during active flashing in aluminum, rigid plastic, and adhesive vinyl for facilities where workers need more detail than the standard message alone conveys.

Yes, our bilingual English/Spanish do not enter when light is flashing signs ensure all workers understand the access restriction enforced by the warning light system regardless of their primary language, particularly important in facilities with automated equipment cells, radiation rooms, and laser labs with diverse multilingual workforces where language barriers could result in a serious injury incident.

For radiation room doors we recommend rigid plastic or aluminum options from our flashing light signs collection with smooth surfaces that can be wiped clean with hospital or laboratory cleaning agents, with aluminum being rust-proof and moisture-resistant and ideal for medical imaging suite doors where cleaning frequency is high, and adhesive vinyl also available for facilities where mounting hardware is not permitted on the door material.
