What do the terms "blanking off" or "blinding" refer to in confined spaces?

In the context of confined spaces, the terms "blanking off" or "blinding" specifically refer to the practice of disconnecting and locking out all machines to prevent unintended startup or release of energy. This is crucial for ensuring the safety of personnel working in confined spaces where exposure to hazardous energies or substances could pose a risk. By implementing lockout/tagout procedures and blanking off equipment, workers can safeguard themselves from potential accidents that could occur from equipment activation while they are working.

This practice is fundamental in confined space safety protocols, as it helps to create a controlled environment where workers can perform their tasks without the fear of sudden equipment malfunctions or energy releases. Proper training and adherence to safety regulations regarding these practices are essential for reducing the risk of injury or fatality in scenarios involving confined spaces.
