High-risk Construction Activities
Worker boundaries for height, confined spaces, excavations, lifting operations and service hazards.
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
High-risk activities require competent planning, appropriate equipment, controlled access and a workable emergency arrangement.
Exam cue: Look for collective protection, inspection status and exclusion arrangements.
Concept 2
Workers must verify authorisation, briefing and controls before entering or starting rather than deciding that experience is enough.
Exam cue: Never enter a confined space or unsupported excavation to improvise a rescue.
Concept 3
Weather, ground, atmosphere, plant movement or service information changes can require work to stop.
Exam cue: Stay outside suspended-load and plant danger zones.
Risk pitfalls and guardrails
Using a ladder as the default for lengthy work.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Entering an excavation after rain without rechecking.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Assuming a cable or pipe is dead because it is not shown on one drawing.
Guardrail: Do not turn course attendance, a signed form or personal confidence into authority for uncontrolled work.
Memory anchors
Plan, Protect, Permit
Severe-consequence work needs competent planning and controlled authority.
Conditions Can Cancel
Weather, ground or atmosphere changes can invalidate permission.
Loads Need Space
Keep people outside lifting and slewing danger zones.
Rescue Is Planned
An emergency is not permission for an unprotected entry.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
