For which reason should a worker check warning stickers on a powered machine?

Checking warning stickers on a powered machine is critical primarily to be aware of hazards while the machine operates. These stickers typically contain crucial safety information about potential risks associated with the machine's operation, including specific dangers that may not be obvious just by observing the equipment. Understanding these hazards enables workers to take necessary precautions, use personal protective equipment, and follow safe operating procedures. This awareness is essential for minimizing risks of injury or accidents while working with or near the machinery.

While identifying the manufacturer, confirming the model number, and learning about the machine's features are useful actions, they do not contribute directly to the immediate safety of the operator or surrounding workers in the same way that understanding the hazards does. Safety information is paramount in ensuring a safe working environment, making it crucial for any worker operating or interacting with powered machinery.
