AFF-X1.02 Use of water for fire extinguishing, the effect on ship stability, precautions and corrective procedures
Condition Behavior Standard

In an approved or accepted course, in simulated shipboard conditions, given a ship's fire and emergency plans and procedures and having one or more fire parties fighting one of the following fire scenarios:

  1. engine-room fire;
  2. cargo hold fire, or
  3. service space fire,

the candidate determines the effect of streams of firefighting water on ship's stability and describes appropriate precautionary and corrective measures that could be taken in accordance with the ship's fire and emergency plans and procedures to maintain or prolong stability.


Note 1 The assessment corresponds to a revalidation component that must be demonstrated in Coast Guard approved training ashore in order for mariners with 1 year of service in the previous 5 years to renew competency in Advanced Firefighting.
  1. The candidate’s qualitative estimates of onboard water retention based on differences between fire-stream flow and run-off based upon calculations, reports, and observations are correct; and
  2. The candidate correctly describes timely and effective precautionary, compensating, and corrective actions that could be taken to maintain or prolong ship's stability based on expectations, predictions, calculations, and observations of effects of firefighting water.
