Demolition and High-risk Attachments
Structural sequence, exclusion, attachment selection, falling material, dust, residual services and machine protection.
How to prepare for a CPCS category Theory Test
Learn the operator's safe decision sequence, connect it to the current category learning outcomes and practise explaining why the manufacturer, task and site controls apply.
Core concepts
Concept 1
Demolition follows the engineered sequence and exclusion arrangements for the structure, plant and attachment.
Exam cue: Link every movement to the demolition plan and structural state.
Concept 2
Residual services, unstable elements, falling debris, dust and limited visibility are reassessed as the work progresses.
Exam cue: Keep people outside debris and machine envelopes.
Concept 3
The machine, cab protection, attachment and endorsement must match height, material and demolition duty.
Risk pitfalls and guardrails
Pulling an element outside the planned sequence.
Guardrail: Do not replace a manufacturer limit, competent plan, physical control or authorised decision with experience or memorised wording.
Using an attachment that exceeds carrier limits.
Guardrail: Do not replace a manufacturer limit, competent plan, physical control or authorised decision with experience or memorised wording.
Memory anchors
Sequence Protects Structure
Do not improvise the order of demolition.
Debris Has Reach
Exclusion extends beyond the immediate tool.
Service Free Must Be Proven
Isolation and confirmation precede work.
Carrier Plus Tool
Compatibility includes mass, pressure and protection.
Dust Is a Hazard
Control exposure and visibility, not just nuisance.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
