What must be done before performing repairs on machinery or equipment?

Before performing repairs on machinery or equipment, it is essential that the power is turned off and that the equipment is blocked against hazardous motion. This practice is crucial for ensuring the safety of the maintenance personnel who will be working on the equipment. When the power is off, there is a significantly reduced risk of accidental activation that could lead to injury. Blocking the equipment against hazardous motion prevents any unintended movement, which can also pose a danger to workers.

Implementing these safety measures not only complies with regulatory standards but also forms a foundational part of any effective safety program within industrial and mining contexts. This proactive approach mitigates risks associated with equipment repairs and creates a safer working environment, thereby protecting workers from potential hazards.
