OSHA 30 Hour Construction Program Practice Test

What type of life line connects at both ends to stretch horizontally?

1. Vertical life line

2. Horizontal life line

3. Retractable life line

4. Fixed life line

The correct answer is: Horizontal life line

A horizontal life line is specifically designed to connect at both ends to stretch horizontally. This type of life line is essential for providing fall protection for workers who are exposed to fall hazards while working on elevated surfaces or in situations where they need to move across different points in a horizontal plane. When properly anchored, a horizontal life line system allows workers to securely attach their safety harnesses or lanyards to the line as they navigate the work area, effectively minimizing the risk of falling. This system can be used in various settings, such as construction sites, maintenance work on roofs, and other scenarios where personnel access elevated locations. Other options, such as a vertical life line, typically run straight up and down, which is not suitable for horizontal movement. A retractable life line involves a mechanism that can extend and retract, providing some degree of freedom of movement but is not specifically designed as a horizontal connection. A fixed life line, while providing support, may not necessarily mean it runs horizontally unless specified. Thus, the choice of a horizontal life line clearly defines its purpose and application in fall protection plans.
