Q

L137 IS A WATER RESCUE UNIT, AS A COVERING OFFICER OFFICER YOU NOTICE ON THEIR POSITIONS BLACKBOARD NEXT TO THE IRONS FF IT READS: IRONS/PRIMARY WATER RESCUER. DO YOU AGREE WITH L137 ASSIGNING THIS POSITION TO A EVERYDAY POSITION LIKE THE IRONS?

A

NO

  1. 1 A member who has been trained in the suit and is familiar with its capabilities and limitations should be designated as the Primary Rescuer. A member with lifeguard experience or a trained scuba diver should be considered for this assignment.
  2. 2 It would not be good practice to assign your primary water rescuer as a riding position. Example, nozzle firefighter is always the primary rescuer. This member may not feel comfortable in the water and you may have someone with more training for that duty. Positions should be discussed and determined at roll call.

Q

THERE WILL BE TIMES WHEN WE SHOULD NOT ENTER THE WATER, WHAT ARE THE FACTORS THA PRECLUDE US FROM ENTERING?

A
  • WATER/WEATHER CONDITIONS
  • LOCATION OF VICTIM
  • SKILL OF RESCUER
  • NIGHT TIME OPS
  1. 2 There will be times when we should not enter the water. This goes for drill as well as a rescue situation. Some factors that would affect this decision are:
  2. 2.1 Water/weather conditions – factors such as wave height, presence of riptides or sweep tides and lightning storms.
  3. 2.2 Location of Victim- how far out the victim is and if they can be reached safely.
  4. 2.3 Skill level of rescuer - can the rescuer reach the victim under the above circumstances or will the rescuer eventually become a victim.
  5. 2.4 Night operations - Members should not be allowed past the line of sight from the shore. Portable lights should be brought to the scene.

Q

HOW MANY TIMES FASTER DOES THE LOSS OF BODY HEAT OCCUR IN COLD WATER THAN IN AIR?

A

•25X

5.2.1 The loss of body heat occurs 25 times faster in cold water than in air. Hypothermia (subnormal body temperature) begins when the body’s core (brain, spinal chord, lungs and vital organs) temperature falls below the level of 98.6 degrees Fahrenheit. Cold water cools the body’s skin and outer tissues very quickly. In approximately 7 to 15 minutes, core body temperature begins to drop significantly, affecting utilization of the arms and legs. Blood pressure, pulse and respiration rates all decrease. Muscles tense and shiver. Irrational behavior (resisting help) is a good indicator of hypothermia.

Q

WHEN THE BODY’S CORE TEMPERATURE DROPS BELOW _____ DEGREES F, THE VICTIM TRANSGRESSES FROM NON AMBULATORY TO UNCONSCIOUS.

A

•90 DEGREES F

5.2.2 When the body’s core temperature begins to drop below 90 degrees Fahrenheit, the victim transgresses from non-ambulatory into unconsciousness. Low core temperature, in conjunction with stress and shock, can cause cardiac and respiratory failure.

Q

IN WHAT WATER TEMPERATURE CAN MAMMALIAN DIVE REFLEX OCCUR?

A

•BELOW 70 DEGREES F.

5.3.1 There are a considerable number of authenticated cases of drowning victims who were submerged in cold water for 30 to 60 minutes and then resuscitated with no brain damage or other serious health effects. Sudden face contact with cold water (below 70 degrees Fahrenheit) initiates a body reflex known as the Mammalian Diving Reflex (MDR).

6.1 There are 4 tides in 24 hours: 2 tides are coming in (High) and 2 are going out (Low). Slack tide is 45 minutes between High and Low tides.

16
Q

WHEN DOES SLACK TIDE OCCUR?

A

•45 MINS BETWEEN HIGH & LOW TIDES

6.1 There are 4 tides in 24 hours: 2 tides are coming in (High) and 2 are going out (Low). Slack tide is 45 minutes between High and Low tides.

17
Q

WHAT IS THE PRIMARY SOURCE OF SWIMMERS IN DISTRESS?

A

RIP CURRENTS

6.2 Rip Tides or Currents - occur when the tide is going out. Rip currents are the primary source of distress in drowning victims. Rip currents pull people into deep water very quickly. This causes the victim to panic which is the leading cause of drowning.

18
Q

WHEN DO RIP CURRENTS OCCUR?

A

•WHEN TIDE IS GOING OUT

6.2 Rip Tides or Currents - occur when the tide is going out. Rip currents are the primary source of distress in drowning victims. Rip currents pull people into deep water very quickly. This causes the victim to panic which is the leading cause of drowning.

19
Q

WHEN ARE SWEEP TIDES MORE PRONOUNCED?

A

•OUT-GOING TIDES

6.3.1 Sweep Tides can also be present in a rescue situation. This tide runs parallel to the beach. It is more pronounced on out-going tides. The waves are diagonal to the beach and can sweep swimmers into a rip current.

20
Q

L121 OBSERVES A SWIMMER IN DISTRESS ON BEACH 40TH STREET. THE LT. NOTICES A SWEEP TIDE OCCURRING-THE TIDE IS RUNNING PARALLEL TO THE BEACH. WHERE SHOULD HE INSTRUCT HIS RESCUER TO ENTER THE WATER?

A

•UPSTREAM OF THE SWEEP

6.3.2 Rescuer should enter the water upstream of the sweep. This will pull the rescuer towards the victim.
