What is indicated by a protective system being described as manufactured or job-built?

A protective system described as manufactured or job-built refers to its construction and form. The term "manufactured" typically refers to systems that are pre-fabricated in a factory setting according to specific standards, ensuring they meet safety codes and can be used safely on various sites. On the other hand, "job-built" refers to structures that are specifically constructed on-site to meet the unique requirements of the excavation work being performed. This duality allows for flexibility in how protective systems can be utilized depending on the setting and the specific risks associated with that environment.

Understanding this distinction is crucial for an excavator operator, as it highlights the importance of choosing the appropriate type of protective system based on whether it is made beforehand or specifically assembled for a particular job. This ensures proper safety protocols and compliance with regulations.
