Final answer:
If a gurney hits an aircraft without visible damage, you should stop and become stationary to assess the situation. Safety is the priority, and thorough inspection and reporting of the incident is required.
Step-by-step explanation:
If a gurney rolls away and strikes the aircraft without causing visible damage, the first action you should take is to stop moving and become stationary until the situation is fully assessed. It is critical to ensure the safety of the patient, yourself, and others in the vicinity.
After stopping, a thorough inspection of the aircraft, the gurney, and the patient should be conducted to ensure there is no hidden damage or injuries that are not immediately visible. Running toward or alongside the ambulance is not advised as it can endanger your safety and potentially lead to further accidents. Immediate reporting of the incident to the appropriate aircraft and medical personnel is also necessary to evaluate and document what occurred.
