Who should supervise the design, installation, and use of horizontal lifelines?

The design, installation, and use of horizontal lifelines should be overseen by a qualified person because this individual possesses the necessary knowledge, experience, and training specific to fall protection systems. A qualified person is defined as someone who has the skills and training to ensure that safety systems, like lifelines, are correctly designed and implemented to protect workers from fall hazards. This includes understanding the engineering principles involved, knowing the relevant safety regulations, and being familiar with the specific conditions of the worksite.

While other roles, such as a safety official or an engineer, may contribute to safety practices and protocols, they may not have the specialized expertise specific to horizontal lifelines. Similarly, a company manager may have oversight responsibilities but would generally not possess the technical qualifications needed to ensure the correct design and installation of these systems. Hence, the responsibilities for such critical safety measures should rest with someone who is recognized as a qualified person in the field of fall protection.
