What does a guard's design need to prevent?

The design of a guard is primarily focused on ensuring the safety of operators and workers by preventing accidental contact with moving parts of machinery. This is crucial because moving parts can pose significant hazards, leading to serious injuries or even fatalities. Guards are engineered to create a physical barrier that restricts access to these hazardous areas while still allowing the machine to function as intended. Proper guard design enhances workplace safety by minimizing the risk of workers inadvertently coming into contact with dangerous components while machine operations are ongoing.

While unnecessary wear, visual obstruction, and employee fatigue are important considerations in machinery operation, they are not the primary purpose of a guard. Guards specifically aim to safeguard against injuries by physically obstructing access to moving parts, thereby promoting a safer working environment for all employees.
