Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

In terms of ladder safety, an extension ladder should be placed at a correct angle of approximately ________ to ensure stability.

1. 30 degrees

2. 45 degrees

3. 60 degrees

4. 75 degrees

The correct answer is: 30 degrees

For ladder safety, placing an extension ladder at the correct angle is crucial for ensuring stability and reducing the risk of accidents. The ideal angle for an extension ladder is approximately 75 degrees, not 30 degrees. This angle allows the ladder to be positioned securely against a wall or another structure while providing optimal support for the user. When the ladder is set at about 75 degrees, it means that for every four feet of height, the base of the ladder should be one foot away from the wall. This configuration allows the ladder to distribute weight evenly and minimize the chances of it tipping over. An angle that is too shallow, like 30 degrees, could lead to instability and a higher risk of the ladder slipping or collapsing. Therefore, adhering to the 75-degree angle is essential for maintaining safety while using an extension ladder in various work environments.
