How do barriers differ from guards?

Barriers and guards serve distinct roles in ensuring safety around machinery. The correct answer highlights that barriers restrict access to certain areas, effectively creating a physical separation between personnel and potential hazards, such as moving machinery or dangerous processes. This separation can prevent individuals from inadvertently entering unsafe zones where they could be injured.

On the other hand, guards specifically protect individuals from direct contact with moving parts or hazards of machines. They are designed to cover or encase dangerous components, reducing the risk of injury from those specific machinery parts. While both barriers and guards contribute to workplace safety, their functions and applications are tailored to particular types of risks; barriers focus on access control, while guards focus on protecting against injury from machinery operation.

By understanding these differences, safety measures can be appropriately implemented to minimize risks in various environments.
