The primary purpose of installing a safety guard on machinery is to protect operators from hazards. Safety guards serve as physical barriers that prevent operators and bystanders from coming into contact with moving parts, sharp edges, or other dangerous components of machinery. By effectively minimizing the risk of injury, safety guards are essential in maintaining a safe working environment. They ensure that operators can perform their tasks without direct exposure to potential dangers, thereby reducing the likelihood of accidents and injuries.

Enhancing performance, increasing visibility, or reducing noise addresses other aspects of machinery operation but does not align with the main function of safety guards. While these factors can contribute to overall productivity and efficiency in the workplace, the primary goal of safety guards is focused on safeguarding individuals from harm.
