Where risk arises
A table saw creates risks of blade contact and workpiece ejection or kickback. Risk includes feeding, removing offcuts, adjusting fences and changing blades. A small machine can cause serious amputations. Assessment must consider the particular operation and how each workpiece is held and guided.

Protection at the cutting point
An upper guard, protection beneath the table and suitable anti-kickback devices form part of the solution. A riving knife helps prevent material closing onto the blade where appropriate to the design and operation. Components are adjusted and maintained according to instructions. They are not removed because they obstruct a cut that may require different equipment.
Feeding and support
Suitable fences, push sticks and supports keep hands away and control long or small workpieces. Freehand feeding must not be improvised where the procedure requires a guide. Material must be compatible with the machine and checked for defects or foreign objects. The table and surrounding area need sufficient space for feeding and outfeed.
Cleaning without exposure
Sawdust and offcuts must not be removed by bringing hands close to a moving blade. Access to dangerous areas requires stopping and energy control appropriate to the intervention. Dust extraction and noise assessment complement mechanical measures. Eye protection does not prevent blade contact or replace a guard.
Example of an excessively short workpiece
On a hypothetical construction site, someone attempts to cut a small wedge. If the workpiece cannot be safely controlled using a fence and push stick, bringing the hand closer is not the answer. A suitable jig or process is selected, the work is prepared and compatibility with equipment instructions and guards is checked.
Checks before use
Blade, fastening, guards, controls and stability are checked. Critical defects require removal from service. The cited NTPs concern construction-site table saws and must not be transferred without analysis to other machines or materials. Training must include auxiliary tasks, during which many dangerous accesses occur.
