OSHA Danger Robot Moves Without Warning Keep Away Sign Stickers

This sign warns workers that the robot moves without giving any audible or visual pre-movement warning meaning it may begin moving, change direction, or extend its reach at any time without notice. The Keep Away instruction tells workers to maintain a safe distance from the robot's working envelope at all times, not just when someone is visibly operating it.

Post at all points on the robot cell perimeter including safety fence gates, perimeter panels, and any location where workers may approach the robot's working envelope. For robots with large reach radii, post signs that reflect the full reach of the robot arm so workers receive the warning before entering the hazard zone.

OSHA 29 CFR 1910.212 (General Machine Guarding) is the primary standard for robotic safety signage. OSHA also references ANSI/RIA R15.06 (Safety Requirements for Industrial Robots) as a recognized industry standard, requiring that robot work cell hazards be communicated through physical safeguarding and administrative controls including perimeter signage.

Yes. Physical safety fencing is the primary safeguard, but OSHA and ANSI/RIA R15.06 recognize that signage is a required complementary administrative control particularly at fence openings, gates, and access points where the physical barrier is interrupted. Signs also communicate the hazard to workers approaching from a distance before they reach the fence.

Danger is appropriate under ANSI Z535.4 for most industrial robot applications, where unexpected movement can cause fatal or severely disabling injuries. The Danger signal word ensures workers give this warning its maximum level of attention.
