1. On what occasions would you need to install a horizontal lifeline?
Horizontal lifelines are typically required in situations where high-altitude work involves lateral movement, and there isn’t enough space to properly attach a traditional safety harness. This could occur during rooftop maintenance, bridge inspections, or any task requiring workers to move horizontally while remaining secure.
2. How should you plan the layout of a horizontal lifeline?
The design should follow the worker's exact movement path. This ensures that the lifeline remains accessible and functional throughout the entire area of operation. Planning should take into account obstacles, structural features, and the specific tasks being performed.
3. How do you decide the length and quantity of a horizontal lifeline?
Firstly, the length should match the worker’s movement trajectory, but each individual lifeline should not exceed 200-300 meters in length. If the site has areas with significant obstructions or steep drops, it may be better to split the lifeline into shorter segments to reduce installation challenges and costs. Secondly, consider the on-site conditions; if certain zones present difficulties, dividing the lifeline might be advisable.
4. How do you determine the number of people who can safely use a horizontal lifeline?
A horizontal lifeline system consists of a main line (the actual lifeline installed) and personal equipment such as carabiners, shock absorbers, and harnesses. While the number of users corresponds to the number of personal devices, the same main line can support multiple individuals switching between sections. However, for safety reasons, the maximum number of users per single main line should not exceed four.
5. What are the current standards for horizontal lifelines?
The primary standards include the Chinese National Standard GB 38454 and the European Standard EN 795-C. These guidelines cover everything from material strength to proper installation practices, ensuring that the lifeline provides adequate protection.
6. Can a horizontal lifeline be secured with just one end of the wire rope?
No, securing only one end is unsafe. Horizontal lifelines experience significant shear forces during a fall, which can cause the wire rope to snap under stress. To mitigate this risk, an energy-absorbing device like a shock absorber and a tensioning mechanism are essential to absorb impact forces and maintain stability.
7. Is it safe to continue using a horizontal lifeline after a fall?
Absolutely not. After a fall incident, the lifeline must be thoroughly inspected by qualified professionals. Any damaged components, including the wire rope or anchorage points, should be immediately replaced before reuse.
8. Should a fall test be conducted after installing a horizontal lifeline? If not, how can you ensure its reliability?
It’s generally discouraged to perform a fall test on the actual lifeline since this could compromise its integrity. Instead, rely on certified products and regular inspections. Choosing a reputable brand and consulting with experts ensures that the system functions reliably without unnecessary risks.
