Simulating load conditions for training purposes or for testing a patient transport litter having an elongate, flexible panel including a periphery and multiple handles attached to the periphery entails placing a water-fillable human body simulator bag on the flexible panel, filling the bag with water to form a water-filled simulator emulating human body weight of an incapacitated person sized to overlay an area of the flexible panel within the periphery, restraining the water-filed simulator within the litter by fastening portions of the periphery to each other with securement straps, and suspending the water-filed simulator by lifting the multiple handles.
