Which type of injury is most likely if machinery is not locked out during maintenance?

When machinery is not properly locked out during maintenance, there is a significant risk of various types of injuries due to unintentional activation of equipment.

Lockout/tagout procedures are critical safety measures that ensure that machinery is completely shut off and cannot be started up again until maintenance or servicing is completed. If these procedures are not followed, the machinery can inadvertently start, leading to potential electrical shock if maintenance workers come into contact with live components. Additionally, severe cuts can occur if individuals are working near blades or other sharp tools that may become operational unexpectedly. Crushing injuries are particularly hazardous as well; workers could get caught between moving parts or equipment that is improperly serviced.

Given this context, the most comprehensive and accurate answer encompasses all potential risks, which justifies the selection of "All of the above." This reflects the reality that neglecting proper lockout/tagout procedures poses numerous dangers, emphasizing the importance of adhering to safety protocols to prevent all types of injuries when working with machinery.
