What type of guard is utilized with option (d) in identification questions?

The type of guard utilized in option (d), which is an adjustable barrier guard, serves a crucial role in machine safety. An adjustable barrier guard is designed to prevent access to dangerous areas of machinery while allowing flexibility in its operation. This type of guard can be modified to fit different sizes or configurations of materials being processed, providing both safety and efficiency. It ensures that operators are kept at a safe distance from moving parts and potential hazards while still enabling the machine to function effectively within various parameters.
