Lockout/tagout procedures are crucial for preventing what during maintenance?

Lockout/tagout procedures are essential for preventing accidental machine startup during maintenance because they ensure that hazardous energy sources are properly isolated and not able to energize machinery while workers are performing maintenance or repair tasks. This practice involves placing locks or tags on energy-isolating devices, making it clear that the machinery should not be operated until the work is complete.

By adhering to these procedures, the risk of injury or fatality caused by unexpected machine operation is significantly reduced. It creates a safety barrier and a clear protocol that maintenance workers must follow, thus ensuring a safer working environment. This focus on isolating energy sources is a fundamental aspect of safety regulations and practices in workplaces where machinery and equipment are involved.
