When using a pick head axe to break glass, which side should be used?

Using the flat side of a pick head axe to break glass is the recommended method because it provides a wider striking surface, which helps to distribute the force more evenly across the glass. This approach reduces the risk of the axe becoming lodged in the glass and enables more controlled, deliberate strikes, leading to a better result. The flat side minimizes the chances of shards splintering randomly and protects the user from potential injury caused by flying glass.

In contrast, using the pointed side would create a more focused impact that could lead to unpredictable breaking patterns and increase the risk of injury, making it less effective for the task of breaking glass safely and efficiently. Similarly, while using either side might seem practical, it is not ideal due to the concerns regarding control and safety when striking glass surfaces. The emphasis on the flat side aligns with best practices in firefighting operations, particularly when considering safety and efficiency during emergency situations.
