Best Practices for Cutting
- All saws: When possible, make sure they are equipped with integrated water delivery systems that continuously feed water to the blade.
- Handheld saws: In addition to water delivery systems, use respiratory protection with an Assigned Protection Factor (APF) when using handheld power saws as follows:
- when working outdoors for longer than four hours per shift
- always when working indoors in an enclosed area
- Fiber-cement handheld saws: When using handheld saws for cutting fiber-cement board outdoors, use saws equipped with commercially available dust collection system. If the above requirements are met, respiratory protection is not required.

- when working outdoors for longer than four hours per shift
- always when working indoors in an enclosed area
