Casualty assessment and immediate care

Prompt, correct first aid saves lives at sea, often hours or days from professional help, so a structured approach is essential. This lesson covers casualty assessment and immediate care.

Entry & progression

Certificate: STCW Medical First Aid Onboard Ship (A-VI/4-1) — to provide immediate first aid in the event of accident or illness aboard, beyond basic elementary first aid. Entry: STCW basic Elementary First Aid. Progresses to Proficiency in Medical Care (A-VI/4-2).

A structured approach

The chain of survival

The primary survey (DR ABC)

  1. Danger — make the area safe for you and for the casualty before approaching.
  2. Response — check whether the casualty responds, and call for help.
  3. Airway — open and clear the airway.
  4. Breathing — check for breathing; if it is absent, begin CPR.
  5. Circulation — control any serious bleeding and treat for shock.

Acting on the survey

  • Assess the scene and the casualty systematically, not at random.
  • Begin resuscitation (CPR) without delay when breathing is absent.
  • Control serious bleeding, immobilise injuries, and treat for shock.
  • Use the ship's medical equipment and record what you find and do.

WARNING — Danger first — do not become a second casualty Never rush to a casualty before making the scene safe. With electricity, fumes, machinery or a fall risk, a rescuer who becomes a second casualty helps no one and makes the situation worse.

TIP — Follow DR ABC every time A structured primary survey — Danger, Response, Airway, Breathing, Circulation — makes sure the life-threatening problems are found and dealt with in the order that matters, even under stress.
