Which practice best describes safe ladder use for upper-floor access?

• A. Maintain three points of contact and keep footing secure
• B. Two hands on the ladder with no foot contact
• C. Keep the ladder vertical with no angle
• D. Place the ladder on soft ground without stabilization

Answer: (C)

Safe ladder use for reaching upper levels depends on setting the ladder at the proper angle, securing it firmly, and moving with controlled balance. The standard safe angle is about 75 degrees, often described as the 4:1 rule: for every four feet of ladder height, place the base about one foot out from the wall or edge. This angle helps prevent tipping or slipping by keeping the ladder stable as you climb. Use level, firm ground and secure the top so the ladder can’t shift, and if you need to go onto an upper surface, extend the ladder a few feet above the landing for a handhold.

As you ascend or descend, maintain three points of contact at all times—two hands and one foot, or two feet and one hand—so you stay balanced and in control. Avoid a vertical ladder with no angle, which removes essential stability, and never place a ladder on soft ground without stabilization or support, which can lead to collapse. In short, the safest practice combines a proper angle, solid stabilization, and continuous three-point contact.
