The three points of contact rules is simple.
When climbing or descending ladders, trucks, equipment, always maintain contact with one hand and two feet, or two hands and one foot.
If you maintain three points of contact while you climb, you can limit your exposure to slips and falls.
Anyone who has ever suffered an injury by falling from a ladder, slipping off equipment or jumping out of a truck, mucker, drills or a bolter can tell you it doesn't require much height to get hurt. In fact, proper ladder or step use accounts for one out of every four injuries to people who use ladders or steps, drive trucks or operate equipment as part of their normal job duties.
