1. In what situations would you need to install a horizontal lifeline? Any scenario involving high-altitude work where horizontal movement is required and there’s no suitable spot to hang a safety harness.
2. How should you position the horizontal lifeline? You should arrange it according to the user's path of movement.
3. How do you decide the length and quantity of the horizontal lifeline? First, determine it based on the user’s movement trajectory, but remember that the length of a single lifeline should not exceed 200-300 meters, and it’s advisable to divide it into two sections if possible. Second, consider the on-site installation conditions. If there’s interference at a specific location, the height difference exceeds 15 degrees, or the installation cost is too high, it’s recommended to split it into two parts.
4. How do you determine the number of people who can use the horizontal lifeline? The horizontal lifeline system includes the main line and personal equipment. The main line is the horizontal lifeline installed on-site, while personal equipment consists of tools like lifeline sliders, connectors (speed differential devices or connecting ropes), and harnesses. The number depends on the number of users, as they can switch between main lines A and B at any time without needing to match the number of users exactly. However, a single main line should not accommodate more than four users.
5. What are the current standards for horizontal lifelines? National Standard 38454 and European Standard EN795-C.
6. Can the horizontal lifeline be secured with just one end of the steel wire rope? No, the horizontal lifeline experiences shear force from the wire rope. Physically and mechanically speaking, when someone falls, the force exerted on the wire rope and its anchor points is tens of times greater than the fall impact force. Therefore, a force-release device—such as a shock absorber—is essential to prevent the wire rope from loosening and increasing the fall impact force. Additionally, a wire rope tensioner with a shock and tension display should be added.
7. Can you continue using the horizontal lifeline after a fall? No, it must be inspected by professionals, and any parts that need replacement should be replaced before it can be used again.
8. Should you perform a fall test after installing the horizontal lifeline? If not, how can you ensure its reliability? It’s recommended not to conduct a fall test. Using Line A for testing doesn’t guarantee the reliability of Line B, and there’s no need to do so. Instead, it’s better to choose a certified lifeline product.
