AB - Able Seaman Deck General and Safety Questions and Answers

Question 1

According to Navigation Rules (Rule 5), what is the primary responsibility of a lookout?

Accepted Answer

To maintain a continuous watch by sight and hearing to detect any risk of collision.

Answer

Rule 5 of the International Regulations for Preventing Collisions at Sea (COLREGS) explicitly states that "Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision." The lookout's sole duty during their watch is to be the eyes and ears of the ship.

Question 2

While working on deck, a shipmate collapses and is not breathing. You are the first to respond. After ensuring the scene is safe, what is your immediate next action?

Accepted Answer

Call for help and check for a pulse.

Answer

In any first aid scenario, the first step after ensuring your own safety is to assess the victim and summon assistance. You should loudly call for help to alert others who can assist and bring necessary medical equipment, while simultaneously checking for vital signs like a pulse to determine the next course of action (e.g., starting CPR).

Question 3

Which of the following items is NOT typically required to be in a lifeboat's SOLAS 'A' Pack or a vessel's emergency grab bag?

Accepted Answer

Personal passports and crew documents.

Answer

While personal documents are important, they are not a required item in a SOLAS-approved lifeboat survival kit or a standard emergency grab bag. The focus of these kits is on immediate survival: distress signaling (flares), medical treatment (first-aid kit), and sustenance (food/water).

Question 4

A vessel is equipped with a Type II Marine Sanitation Device (MSD). What is the primary function of this system?

Accepted Answer

To biologically treat and disinfect sewage to a high standard before discharge.

Answer

Type II MSDs are flow-through treatment systems that use biological processes and disinfection to treat sewage, producing an effluent with low fecal coliform and suspended solids counts, making it safe for discharge in permissible waters. Type I devices perform maceration and disinfection, while Type III devices are holding tanks.

Question 5

When rigging a pilot ladder, which of the following is a critical SOLAS requirement?

Accepted Answer

The bottom four steps must be made of rubber or a resilient synthetic material.

Answer

SOLAS regulations (V/23) specify construction details for pilot ladders to ensure safety. A key requirement is that the four lowest steps must be made of rubber or a similar resilient material to prevent damage from impact against the pilot boat or ship's hull. Securing methods must be robust, and the ladder must be clear of discharges and within the mid-ship half length of the vessel where possible.
