Noise and Vibration
Assessment and prevention of hearing damage, hand-arm vibration and whole-body vibration.
How to prepare for the CITB MAP test
Build manager-level decisions around role, prevention, coordination, verification and learning rather than memorising isolated site rules.
Core concepts
Concept 1
Risk depends on magnitude and duration, so exposure assessment must reflect real tools, tasks and work patterns.
Exam cue: Use reliable exposure information rather than judging by discomfort alone.
Concept 2
Quieter or lower-vibration methods, maintenance, isolation and reduced exposure precede reliance on PPE or rotation.
Exam cue: Change the equipment, process or schedule to reduce exposure at source.
Concept 3
Information, health surveillance where appropriate and early symptom reporting support prevention but do not cure poor controls.
Exam cue: Investigate symptoms promptly and review everyone with similar exposure.
Risk pitfalls and guardrails
Issuing hearing protection without controlling unnecessary noise.
Guardrail: Do not solve a design, engineering or organisational failure only with a briefing, warning sign or PPE.
Using a generic tool vibration figure without actual trigger time.
Guardrail: Do not solve a design, engineering or organisational failure only with a briefing, warning sign or PPE.
Rotating workers through a hazardous process without reducing total exposure.
Guardrail: Do not solve a design, engineering or organisational failure only with a briefing, warning sign or PPE.
Memory anchors
Magnitude × Time
Noise and vibration risk depend on exposure level and duration.
Buy Quiet and Low-Vibration
Equipment selection can remove risk before work starts.
Maintain the Tool
Worn tools, consumables and bearings can increase exposure and reduce control.
Protective Equipment Is Later
Hearing protection supplements source and organisational controls.
Trigger Time Is Work Time
Estimate actual contact with a vibrating tool, not the whole shift automatically.
Symptoms Trigger Action
Early hearing, finger, hand or back symptoms require competent review and control reassessment.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
