What should be ensured before operating any machinery?

Before operating any machinery, it is crucial to ensure that all protection guards are in place. These guards are safety features designed to prevent accidental contact with moving parts, which could lead to serious injuries. They help to protect the operator and anyone nearby from hazards associated with the machinery's operation. Ensuring that all guards are in place is a fundamental safety requirement and a step that must be taken to create a safe working environment.

In comparison, while having warning lights, keeping machinery clean and maintained, and inspecting for cosmetic damage contribute to overall safety and efficiency, they do not directly address the immediate risk of injury that can occur from operating machinery without proper protection. Protection guards are specifically engineered to mitigate risks during operation, making their presence essential for safety protocols.
