Apparatus, methods, and non-transitory computer readable media are described for detecting an operational safety condition within a container using a scanning sensor node deployed within the container and above a storage space within the container. For example, the method uses the scanning sensor node to sense if the container is in a closed state and monitors the storage space from above the storage space while the container is in the closed state. The method then has the scanning sensor node detecting a movement within the container based upon the monitoring of the storage space while in the closed state. Such a detected movement is indicative of the operational safety condition. The method then has the scanning sensor node transmitting an alert to a managing node over a wireless communication interface of the scanning sensor node, where the alert is associated with the operational safety condition within the container.
