BFQ 02-04 Crew Rest Utilization Flashcards
What are the signs of fatigue personnel?
- Decreased coordination
- narrow attention span
- lower standard of performance
How does time of day affect fatigue?
- The body is trained to release energy during the day and store it during the night. Crews should be well rested for night watch.
How does sleep duration and quality affect?
- 8 hours of sleep needed
- Anything less than 6 hours, you start to lose mental faculty and other issues.
What is it about the stability of sleep/wake schedule?
- Inconsistent sleep/wake patterns can disrupt the biological clock and result in reduced alertness, severe sleepiness, insomnia, and degregation of of mental alertness.
Explain Continuous Vs. Split Sleep
- Sleep debt is incurred when sleep is split.
- Certain patrols such as bar patrols can add to split.
Explain Periods of Sustained Wakefulness
- Work exeeding 12 hours will result in fatigue and performance schdule.
Discuss crew endurance management considerations for urgent operations.
- A mission of sufficient importance that the District Commander elects to execute it with a fatigued boat crew.
What is the minimum requirements for crew rest before assuming alerty duty and during a 24-hours duty period.
- Crew should have a minimum of 8 continuous hours of rest before assuming alert duty.
- 8 hours of continuous rest in every 24 hour period.
When should a crew fatigue message must be sent and when a fatigue situation will be cleared.
- When a station’s alert posture is comprimised due to crew fatigue.
- It should be cancelled when the fatigue situation no longer exists.
What are station work periods for duty crews?
- They are restricted to light operations, training, or Station work.
- ## Training limited until some time between 2000 and 2200.
When is underway time calculated to determine underway limits and discuss how to calculate total mission hours during a 24-hour period.
- Underway time begins when the member reports to the designated place to prepare for a specific boat mission and ends when the mission is complete.
- Includes boat and trailer sorties.
- Calculated during a single mission or an accumalation of missions.
Identify fatigue inducing factors.
-
What is a higher risk mission?
Any mission between 2300 and 0500
- Interrupts normal physiological cycles.
What are the required sleep periods after a higher risk mission?
-Less than a six-hour sleep period – they need at least a six-hour
sleep period to control fatigue on subsequent missions.
-More than a six-hour sleep period but less than a seven-hour sleep
period – they need at least a two-hour sleep period to control
fatigue on subsequent missions.
What are the maximum underway hours for boat type?
- Based on 4ft seas and HWX
- 40ft and above - 10/8/6
- Less than 40 ft - 8/6/N/A
- Trailering - 350 miles or 8 hours.
