Using Four-Wheel Carts in the Roofing Trade:
This animation recreates the real-life story of a roofer who ruptured his Achilles tendon while maneuvering a heavily loaded cart. Three solutions are recommended with embedded scientific evidence showing that even a simple solution like team pulling could have prevented this injury. The moral of the Tortoise and the Hare is embedded in the animation to remind audiences to pay attention to the danger of ergonomic hazards.
