Steps
Identify whether the cut uses a handheld power saw, walk-behind saw, or stationary masonry saw, since each has its own Table 1 entry with different required controls.
For handheld saws, use one integrated with water delivery to the blade, applying water at a rate sufficient to minimize visible dust per manufacturer instructions.
For stationary masonry saws, use a saw with an integrated water delivery system that continuously feeds water to the blade.
Check the current Table 1 respirator requirement for that specific saw type and duration/location before assuming none is needed.
If dry-cutting is unavoidable, treat the task as outside Table 1 and perform an independent exposure assessment against the PEL.
Known gotchas
Table 1 assumes continuous, functioning water delivery -- an intermittently sprayed hose does not satisfy the control method.
Handheld, walk-behind, and stationary saws each have separate Table 1 rows; a respirator requirement from one entry does not automatically apply to another.
Confirm current respirator/APF details directly on osha.gov's 1926.1153 page, since OSHA fact sheets can lag behind the current regulatory text.
