Gravity, you and fall protection. Or know before you go.
Gravity is everywhere. Now there’s a profound statement. My whole life, I was reminded of gravity whenever I fell or tripped. I suspect this is applies of all people.
This knowledge applies especially to those who work at heights. If your job involves working on: ladders, scaffolding or other elevated working surfaces understanding that fall protection (railings or personal fall arrest equipment) can help you avoid injury from a fall is most important. The human body is not designed to safely absorb a fall impact. The best protective step is to avoid the fall.
