Correct answer: B — Send a METHANE message and declare a major incident standby or declaration

Option B is correct because A structured METHANE report communicates location, hazards, access, casualty numbers and resources to trigger the right response. Option A is less appropriate because oxygen may be supportive, but it does not address the defining time-critical problem first; option C is less appropriate because vascular access is useful, but it should not delay the immediate priority. Option D is less appropriate because it is plausible in a different scenario but suboptimal for the features described; option E is less appropriate because delay would increase clinical risk. Clinical pearl: in DipIMC-style questions, the best answer is the intervention that changes outcome earliest in the pre-hospital phase.
