Based on the limited provided video transcript, using an extension ladder involves pulling it out and performing a test to ensure it's at the proper angle: standing with your toes against the base of the ladder.
While the transcript is incomplete, a full explanation of how to use an extension ladder safely would include the following steps:
- Choose the Right Ladder: Select a ladder of appropriate length for the job. Calculate the necessary ladder reach by adding your height to the height of the highest point you need to reach. Remember that ladders should extend at least 3 feet (0.9 meters) beyond the support point.
- Inspect the Ladder: Before each use, inspect the ladder for any damage, such as loose rungs, cracked rails, or broken locks. Never use a damaged ladder.
- Set Up the Ladder: Place the ladder on a firm, level surface. Avoid placing it on uneven ground, unstable materials, or slippery surfaces.
- Angle the Ladder Properly: The ladder should be angled at approximately 75 degrees. A simple test, as mentioned in the transcript, is to place your toes against the base of the ladder and extend your arms. Your hands should comfortably touch the rungs at shoulder height. Another way to calculate the proper distance is the "4 to 1" rule: for every four feet of height, the base of the ladder should be one foot away from the wall.
- Extend the Ladder: Extend the ladder to the desired height, ensuring that the locking mechanisms are securely engaged. Overlap sections should follow the manufacturer's recommendations.
- Secure the Ladder: If possible, secure the top of the ladder to prevent it from slipping. Use ladder stabilizers or tie-downs.
- Climb Safely: Maintain three points of contact with the ladder at all times (two hands and one foot, or two feet and one hand). Avoid carrying heavy loads while climbing. Climb slowly and deliberately.
- Work Safely: Do not overreach. Keep your body centered between the rails. Avoid working in windy conditions or near electrical hazards.
- Descend Carefully: Descend slowly and deliberately, maintaining three points of contact.
It is important to consult the ladder manufacturer's instructions for specific safety guidelines and usage instructions for your particular ladder model.
