To ensure the safe use of A-frame ladders and prevent falls and injuries, follow these key precautions and guidelines:

1. Selection and Inspection:

• Choose the right type and size of ladder for the job, considering the required height and weight capacity. Ensure it is Underwriter's Laboratory approved.
• Before each use, inspect the ladder for any defects such as loose or cracked rungs, split side rails, and worn shoes. Also check the rung locks. Remove defective ladders from service and tag them appropriately.
• Verify the ladder's duty rating to ensure it can support the user and tools.

2. Setting Up the Ladder:

• Clear the area of debris and obstructions. Block off the area around the ladder's base to prevent accidental bumps.
• Set the ladder on a dry, level, and solid surface. Use the "heel test" to check the ground's firmness; if your heel sinks more than 1 inch, use a base like plywood.
• For extension ladders, position the base one foot away from the building for every four feet of height.
• When accessing a porch or roof, the ladder's side rails should extend at least 3 feet above the landing. Secure the ladder by tying it to the building for extra stability.
• If placing a ladder in front of a door, secure the door shut.
• Use ladder stabilizers when necessary.

3. Climbing and Working Safely:

• Maintain three points of contact with the ladder at all times (two hands and one foot, or one hand and two feet).
• Face the ladder when climbing up or down.
• Use a tool belt or hoist to lift tools, avoiding carrying them in hand.
• Keep your belt buckle centered between the ladder's side rails.
• Avoid overreaching, pulling, leaning, stretching, or making sudden moves.
• Reposition the ladder instead of overreaching.
• Do not stand on the top step of a stepladder or the top three rungs of an extension ladder.
• Allow only one person on the ladder at a time, unless the ladder is specifically designed for multiple users.

4. Maintaining the Ladder:

• Change the ladder's shoes regularly.
• Lubricate metal bearings, locks, and pulleys.
• Protect wood ladders with a clear sealer to prevent hiding defects.

5. Electrical Safety:

• Maintain a distance of at least 10 feet from power lines.
• Use a fiberglass ladder instead of an aluminum ladder when working near electricity.

6. General Safety Practices:

• Train workers on proper ladder use, including inspection, setup, climbing, and hazard recognition.
• Use ladders only for their intended purposes.
• Avoid using ladders in hazardous weather conditions such as high winds or storms.
• Never move or shift a ladder while someone is on it.
• Barricade or secure ladders in high-traffic areas to prevent displacement.
