: Specific guidelines (Annex A) for preparing the environment to ensure safe operation, including floor and ground conditions. Protective Measures
By doing so, you protect not only your workforce but also your investment in automation. A compliant AGV fleet is a productive, insurable, and scalable fleet.
Tens of thousands of autonomous vehicles are now operating in industrial environments worldwide. As these machines become more capable—navigating complex environments, carrying loads that can exceed 2,000 kg, and sharing tight spaces with human workers—the potential consequences of inadequate safety measures become correspondingly severe. A 2‑tonne autonomous forklift moving through a crowded warehouse aisle at speed is a genuine hazard if its sensing, braking, and alerting systems are not rigorously engineered.
: A comprehensive list of significant hazards relevant to driverless trucks (Annex B). JLC Robotics Key Exclusions ISO 3691-4 does cover safety requirements for: Operations in severe conditions (e.g., extreme cold, strong magnetic fields). public roads or in public zones. Potentially explosive or nuclear environments. The transport of unintended passengers or hazardous materials (e.g., molten metals). Official Access to the Proper Text Iso 3691-4 Pdf
A landmark update to the standard was published on (ISO 3691-4:2023), superseding the 2020 edition. This update incorporates several technical changes to keep pace with evolving AGV technology. Key modifications include:
Continuous operation at full rated speed allowed. Low human risk. Between 0.12 and 0.5 meters
ISO 3691-4 outlines numerous safety requirements to reduce risks of collision, crushing, and unintended movement, thereby enhancing personnel safety and production stability. : Specific guidelines (Annex A) for preparing the
: As the 2027 compliance deadline approaches for adapting to new machinery regulations, many end-users have begun writing "compliance with the 2023 version of ISO 3691-4" directly into their tender documents.
Validation of the fleet management software to prevent vehicle routing conflicts. Clearly marked guidepaths, signage, and floor demarcations.

Integrators are responsible for the entire "system," which includes the environment. They must map out the operational zones, ensure adequate floor conditions, install proper signage, and configure the vehicle's safety fields according to the physical layout of the facility. For End-Users (Facility Owners)
Vehicles capable of dynamic routing and navigating around obstacles.
The ISO 3691-4 PDF outlines a comprehensive framework of safety requirements designed to mitigate risks like collisions, crushing, and unintended movement, thereby protecting personnel and ensuring stable production. Key requirements include:
The standard clarifies the division of responsibility between the vehicle manufacturer and the factory system integrator, which is crucial during deployment.
