In manufacturing planning, what describes the space around a workstation needed for safe operation?

• A. Yarn
• B. Work envelope
• C. Young's Modulus
• D. Work hardening

Answer: (B)

The space around a workstation needed for safe operation is described by the work envelope. This concept defines the spatial boundaries within which a worker and any equipment can operate without risk, taking into account how far a person can reach, the clearances required for moving parts, and access for maintenance or emergency actions. In manufacturing planning, outlining the work envelope helps ensure there’s enough room for tasks to be carried out safely, for tools and devices to operate without collisions, and for ergonomic comfort and safe movement. It’s also relevant to robotics, where the work envelope represents the space the robot can reach and move through without safety hazards. The other terms don’t fit because they refer to material properties or textile terminology, not to the safe spatial layout around a workstation.
