Dust, asbestos, substances, noise, vibration, manual handling, hygiene and early symptom reporting.
How to prepare for an IOSH construction course
Use the developing site scenario to practise proportionate decisions, then confirm the exact assessment and delivery arrangements with your IOSH-approved provider.
Core concepts
Concept 1
Construction health hazards can cause irreversible disease after exposures that do not produce immediate pain.
Exam cue: Ask what creates the exposure and how it can be prevented at source.
Concept 2
Controls should eliminate or reduce exposure at source before relying on respiratory, hearing or other personal protection.
Exam cue: Check that protective equipment is selected, fitted, maintained and compatible.
Concept 3
Suspect materials, defective controls and work-related symptoms should be reported early through the site system.
Exam cue: Treat health surveillance as a check, not a substitute for control.
Risk pitfalls and guardrails
Dry sweeping hazardous dust.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Disturbing suspect asbestos to identify it.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Using PPE as the only response to uncontrolled exposure.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Memory anchors
Silent Can Be Serious
No immediate pain does not mean the exposure is safe.
Source Before Self
Control the source before depending on personal protection.
Suspect, Stop, Report
Do not disturb an unknown material until it is assessed.
Symptoms Speak Early
Prompt reporting can protect the worker and others.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
