When using a circular saw what should you do with a 2x4 that cannot be held safely?

When using a circular saw on a 2x4 that cannot be held safely, it's essential to use a stable work surface, such as a saw horse or workbench, to support the wood. You can also use clamps to secure the 2x4 in place, preventing it from moving during the cut. If neither option is available, consider using a push stick or a jig to guide the saw safely while keeping your hands away from the blade. Always prioritize safety by wearing appropriate personal protective equipment.
