Mechanical Hazards: Machinery and Tools
Moving parts, stored energy, sharp edges, hand tools and unsafe intervention around equipment.
How to prepare for Working Safely
Build a simple worker-level sequence: notice the real hazard, identify exposure and harm, use the strongest available control, and report or escalate weakness.
Core concepts
Concept 1
Entanglement, crushing, shearing, cutting, impact and ejection can arise from moving machinery and tools.
Exam cue: Identify every movement and energy source before intervention.
Concept 2
Guards, interlocks, isolation and suitable equipment control exposure more reliably than caution alone.
Exam cue: Keep safeguards in place and use the authorised isolation method.
Concept 3
Cleaning, adjustment and maintenance can expose people to unexpected movement or stored energy.
Risk pitfalls and guardrails
Removing a guard for a quick task.
Guardrail: Do not normalise a familiar hazard or replace a stronger source control with a warning, procedure or PPE alone.
Assuming switched off means isolated.
Guardrail: Do not normalise a familiar hazard or replace a stronger source control with a warning, procedure or PPE alone.
Memory anchors
Guard the Movement
Prevent access to dangerous moving parts.
Off Is Not Isolated
Secure every energy source before intervention.
Tools Must Fit
Use suitable, maintained equipment for the task.
Stored Energy Surprises
Pressure, gravity and springs can release after shutdown.
Defects Mean Stop
Remove unsafe tools from use and report them.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
