Gravity. One of the most powerful forces in the universe. Ask any astrophysicist. Hey, I work in construction, building things. What do I care of gravity? Anytime a work task need be carried out above a lower surface the potential for a fall exists. Falls can occur, you guessed it, due to gravity.
You have likely heard the old saying, what goes up must come down. Well, not necessarily. The use of fall protection devices can defeat gravity. Guardrails, nets, personal fall arrest systems can all prevent a worker from experience the negative side of gravity, namely, falls. You don’t need to be an astrophysics to appreciate gravity, you simply need to take a simple step of preventing falls (gravity effects) and protect your earthly assets, workers.
