Tools, equipment and workshop safety
What the domain tests
Tools, equipment and workshop safety tests whether you can choose the right tool, use it correctly and control risk. Expect identification of hand tools and machines, maintenance checks, PPE selection, machine guarding, and safe sequencing. Safety answers must be specific to the operation, not a list of general rules.
Core rules and concepts
- Check the tool and machine before use: cords, plugs, guards, blade tension, drill-bit tightness and emergency stops.
- Secure work with a vice, clamp or fixture. Keep hands clear of the cut line and never hold small work by hand on a drill.
- Wear eye protection for cutting, drilling and chiselling; use dust extraction for wood and fume extraction for solder and paint. Tie back hair and remove loose clothing.
- Do not wear gloves near rotating machinery. Use a brush, not a hand or compressed air, to clear swarf.
- Isolate a machine before changing blades, bits or belts. Remove the chuck key immediately after tightening.
- Report damage and take faulty equipment out of use.
Worked example
To drill a 6 mm hole in mild steel on a pillar drill: mark the centre, centre-punch it, clamp the workpiece to the table, fit and tighten a 6 mm bit, set a speed suited to steel, and wear goggles. A pilot hole may be used for accuracy. Apply cutting fluid, feed steadily, and clear swarf with a brush. The reasoning is that clamping prevents the bit grabbing and spinning the work; the correct speed limits overheating; the chuck key must never remain in the chuck.
Traps that cost marks
Wearing gloves at a rotating drill, holding work by hand, removing a guard for convenience, filing without a handle, or clearing swarf by hand are unsafe and lose marks. “Be careful” is not a control measure; name the guard, clamp, PPE or procedure.
