Here are five key safety reminders for using a frame ladder:

1. Inspect the ladder before use: Look for any visible defects that could cause injury, such as structural damage [1]. If defects are found, immediately tag the ladder as "Dangerous: Do Not Use" and remove it from service until repaired or replaced 1, 2.
2. Maintain three points of contact: Always face the ladder and maintain three points of contact (two hands and one foot, or two feet and one hand) when climbing up or down [2].
3. Secure the ladder: Use the ladder only on stable and level surfaces unless it is secured to prevent accidental displacement 3, 5. If the ladder is placed in a location where it could be displaced by workplace activities or traffic, secure it or use a barricade 3, 5.
4. Proper Angle: Non-self-supporting ladders should be used at an angle where the horizontal distance from the top support to the foot of the ladder is approximately one-quarter of the working length of the ladder [3].
5. Avoid carrying loads: Do not carry any object or load that could cause you to lose balance and fall while climbing 2, 5.
