Personal protective equipment and safe use of hand and power tools
This domain tests PPE selection and tool safety. PPE must match the hazard, fit the user and be maintained; tools must be suitable, inspected and used by trained workers.
Core rules
- Select PPE after assessing the hazard. Check compatibility, for example eye protection with prescription glasses and hearing protection with a hard hat.
- Inspect PPE before use. Replace damaged straps, cracked lenses, torn gloves or worn harnesses. Store PPE clean and dry.
- Hand tools: use the correct size and type, keep cutting edges sharp, secure the workpiece, cut away from the body and never use a tool with a loose handle.
- Power tools: check the lead, plug and guard; use the correct voltage and RCD protection; isolate before changing blades or bits; keep loose clothing and hair away from rotating parts.
Worked example
An angle grinder is needed to cut a steel bar. The guard is missing and the lead is taped. The correct response is to stop: fit the guard, replace the damaged lead, use eye and face protection, hearing protection and a safe stance, and barricade the sparks. The reasoning is that the guard and lead are engineering controls; PPE alone would not stop a burst disc or electric shock.
Traps
Do not wear gloves near rotating tools where they can catch. Do not remove guards for speed. Do not use a damaged tool because 'it still works'. Do not assume one type of glove protects against every chemical.
