What potential hazard arises from workers cleaning up a table without cutting the power?

The potential hazard of electrification caused by pinch is a significant concern when workers are cleaning up a table without cutting the power. When equipment or tools remain powered on, there is a risk that workers could accidentally touch live electrical components or machinery. This could result in a pinching or squeezing motion, inadvertently leading to an electrical shock or other injuries.

When working around powered equipment, it's crucial to ensure that the machinery is de-energized to prevent any unintended contact with energized parts. This practice is not only a safety precaution but also complies with workplace safety regulations designed to protect workers from electrical hazards.

Chemical exposure and thermal burns, while valid concerns in different contexts, do not directly relate to the scenario of cleaning up a powered table. In this case, electrification from inadvertently making contact with live electrical systems poses the most immediate and severe risk.
