How can I safely and effectively rip wood with a circular saw?

To safely and effectively rip wood with a circular saw, follow these steps:

1. Measure and mark the cut line on the wood.
2. Adjust the saw blade depth to slightly deeper than the thickness of the wood.
3. Use a straight edge guide or fence to guide the saw along the cut line.
4. Hold the saw firmly with both hands and start the cut with the blade clear of the wood.
5. Keep a steady pace and let the saw do the work without forcing it.
6. Wear safety goggles and hearing protection, and keep hands clear of the blade.
