Equipment Safety and Physical Hazards
Electrical, fire, laser, radiation, gas, pressure and environmental hazards plus systematic equipment safety responses.
How to prepare for the current Primary FRCA MCQ
Build mechanisms first, practise calculations with units, connect equipment to failure modes and finish every SBA by choosing the single best answer to the exact lead-in.
Core concepts
Concept 1
Electrical, fire, laser, radiation, pressure and gas hazards require source control, barriers, monitoring and rehearsed response.
Exam cue: Identify hazard, energy source, path to harm, safeguards and immediate isolation step.
Concept 2
Equipment safety depends on checks, standards, human factors, maintenance and reporting as well as device design.
Exam cue: Protect the patient before preserving equipment evidence and reporting the event.
Risk pitfalls and guardrails
Assuming an intact earth removes every patient-current hazard.
Guardrail: Do not choose an option merely because it states a true fact; choose the one that best answers the exact lead-in under the stated conditions.
Resetting and reusing failed equipment before the fault is understood and authorised as safe.
Guardrail: Assess the patient first and distinguish physiology from artefact or equipment failure.
Memory anchors
What distinguishes macroshock from microshock?
Macroshock passes externally through the body; microshock is very small current delivered close to the myocardium through an invasive conductor.
What reduces ionising-radiation exposure?
Minimise time, maximise distance and use appropriate shielding.
What supports an operating-theatre fire?
An oxidiser, an ignition source and fuel; prevention and response break this triangle.
What follows an equipment fault?
Protect the patient, remove or isolate the device, preserve evidence, report it and await authorised assessment.
Why are checklists not sufficient alone?
They support reliability, but vigilance, training, clear interfaces, maintenance and a rescue plan remain necessary.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
