Forklift Safety with RTLS
According to Operational Health and Safety Administration (OHSA) forklifts lead to about 85 fatal accidents and 34,900 accidents every year in the United States. Implementing RTLS significantly enhances safety, helping to minimize accidents and ensure a secure working environment. Below are key features of RTLS that contribute to forklift safety:
Collision Avoidance
One of the primary benefits of RTLS is its ability to enhance collision avoidance, which is critical in preventing accidents involving forklifts and pedestrians. Here’s how RTLS contributes to safer operations:
Real-Time Alerts: RTLS provides immediate notifications to operators when another forklift or pedestrian enters their path. For example, if a forklift is approaching an intersection or exceeding a safe speed in a high-traffic area, the system can alert the operator through visual signals, and auditory warnings, or even slow the vehicle automatically.
Enhanced Situational Awareness: RTLS systems can display critical information about the operational environment, such as nearby people, other forklifts, or obstacles, on screens in the forklift cab. In addition, RTLS can function as a "virtual mirror," providing visibility at blind intersections or around corners.
Integration with Safety Equipment: RTLS can be paired with other safety devices such as proximity sensors and cameras to create a comprehensive safety solution.
Historical Data Analysis: RTLS collects detailed data on near-miss incidents and operator behavior, allowing management to analyze trends and pinpoint areas for improvement. Reviewing this data helps identify hazardous zones or risky behaviors, enabling targeted interventions like adjusting traffic flows or implementing retraining programs.
Geofencing for Safety
Geofencing is another powerful feature of RTLS that enhances forklift safety by creating virtual boundaries within the operational area. Key aspects of geofencing include:
Designated Zones: RTLS allows organizations to establish specific zones for forklift operations, effectively preventing them from entering hazardous areas. For example, in zones where pedestrian movement is frequent, such as near packing stations or break rooms, geofencing can keep forklifts out.
Automated Alerts: The system triggers alerts when a forklift crosses designated boundaries. Operators receive immediate notifications, which can be sent to their mobile devices or displayed on their vehicle screens. This feature helps enforce safety policies and allows supervisors to monitor adherence in real-time.
Customizable Parameters: Geofencing can be customized to accommodate different operational needs. Organizations can adjust parameters based on shift changes, special events, or increased pedestrian traffic during peak hours, ensuring that safety measures are always relevant.
