case. The SMC is often automatically assigned by prearrangement. For
simple cases, the SMC is normally the lowest organizational level that
can efficiently handle the case. More complicated cases may require
specific SMC assignment by RCC.
B. The SMC function may be transferred between units or persons.
Complications or the need to acquire larger or additional facilities may
make it necessary to transfer SMC to a unit that can more readily
coordinate the case, or a capable unit closer to the scene. Changes in
a case may also warrant transfer to a lower organization level.
440 INCIDENT EVALUATION
Evaluation of the incident is the first SMC responsibility.
Information, judgment, and experience are necessary to place the
incident in one of the Emergency Phase classifications discussed in
paragraphs 450-453, and to determine the urgency and extent of SAR
response.
441 Type of Incident and Severity
A. Information needed for evaluation includes the type of craft
involved and the nature and apparent severity of the incident.
B. A marine vessel SAR incident is considered probable or actual
when:
1. A distress condition, such as fire, sinking, or collision, is
reported.
2. An electronic distress signal is transmitted, or a visual or
audio distress signal is used.
3. A vessel is overdue, is unreported, or misses a position
report. SRUs usually are not dispatched until after a careful
evaluation of factors such as the estimated length of the
voyage, fuel and food endurance, type of craft, operator
experience and habits, and weather and sea conditions. Each
incident must be judged individually.
