In a typical lockout procedure, which steps are involved?

In a typical lockout procedure, closing off auxiliary lines and controls is a crucial step as it ensures that all sources of energy are effectively isolated before any maintenance or repair work begins. This step protects workers from the accidental release of energy, which could lead to serious injuries. When auxiliary lines and controls are properly closed, it reduces the risk of unexpected machine movement or the energization of equipment that could happen if those controls remained active.

The other choices do not align with best practices for lockout procedures. For instance, turning on auxiliary equipment would put workers at risk, as it would negate the very purpose of the lockout, which is to create a safe working environment. Ignoring support equipment is also dangerous, as it could leave unaccounted energy sources that can still pose risks to workers. Adjusting safety protocols, while important, does not wholly encompass the critical actions of isolating energy sources that are fundamental to lockout/tagout procedures. The emphasis on closing off auxiliary lines and controls ensures safety by systematically addressing all potential energy sources before maintenance begins.
