What is a safety concern when operating a table saw?

• A. Using a dull blade
• B. Using the table saw miter gauge with the table saw fence
• C. Not wearing a safety mask
• D. Cutting small pieces of wood

Answer: (B)

Using the table saw miter gauge with the table saw fence presents a significant safety concern because it can lead to a dangerous situation known as "kickback." When the miter gauge is aligned with the fence, it can guide the workpiece improperly, causing it to bind against the blade. This binding can cause the workpiece to be forcibly propelled back toward the operator, which can result in serious injury.

In contrast, other options, while they may also relate to safety in some manner, do not specifically involve the same degree of risk as combining the miter gauge with the fence. For instance, using a dull blade might affect the quality of the cut and could require more effort, but it doesn't directly create an immediate hazardous situation like kickback does. Similarly, not wearing a safety mask pertains more to respiratory protection rather than risk during the operation itself. Cutting small pieces of wood can be risky, but the specific combination of a miter gauge with the fence stands out due to its direct connection to a potentially fatal accident during operation.
