  * Back board with tie down straps and cervical collar.
  * Whistles.
  * First aid kit.
  * Automatic electronic defibrillator (known as AED).
  7-30. Lifeguards must have a current American Red Cross Lifeguard Training certificate and must be
  certified in first aid and cardiopulmonary resuscitation (known as CPR). Lead and assistant instructors should
  be strong swimmers. Ideally all instructors have cardiopulmonary resuscitation training and Water Safety
  Instructor certificates and have passed the CWST.
  7-31. Non-swimmers require extra training time. Those who do not self-declare as non-swimmers should be
  given extra swim training if they fail the two minute buoyancy test—treading water and sculling for two
  minutes in ACUs and boots without going underwater or touching the bottom of the pool. Extra swim training
  time provides Soldiers training to perform the two strokes necessary to pass the basic survival swimmer—
  the sidestroke and breaststroke.
  BASIC SURVIVAL SWIMMER
  7-32. Soldiers must successfully complete the following three training tasks to for basic survival swimmer.
  Soldiers will wear ACUs, boots, and improved outer tactical vest (IOTV) without plates. Soldiers will carry
  an M16 or M4 series training aid for tasks 2 and 3:
  * Task 1: Trouser inflation and float.
  * Task 2: Bob and travel.
  * Task 3: Two-Stroke test (sidestroke and breaststroke).
  TASK 1: TROUSER INFLATION AND FLOAT
  7-33. Task 1, trouser inflation and float, consists of the following four steps:
  * Perform stride entry by leaping off the edge of the pool deck into the water with the trunk leaning
  forward, the head up, the legs spread in a stride position (one forward, the other back), and the
  arms extended sideward (palms facing downward). Immediately upon entry, the legs move
  together and the arms move vigorously downward slapping the water upon entry. This technique
  keeps the head above water and allows the Soldier to maintain visibility.
  * Use the emergency pull strap on the IOTV to release it, allowing the parts IOTV to fall to the
  bottom of the pool. Soldiers collect the IOTV after completing Task 3.
  * Perform a hanging float and remove one boot at a time. Place the first boot under an arm while
  untying the other boot. Tie the laces together and put the boots around the neck, resting each boot
  on each side of the chest. Remove trousers, button the fly, and tie-off each trouser leg individually
  using an overhand knot.
  * Inflate the trousers using the sling or splash method. Once the trousers are inflated, gather-in the
  waist band and twist to seal the air inside the trousers. While grasping the twisted waist band,
  climb in between the trouser legs and place one leg under each arm. Float for two minutes.
  Sling Method
  7-34. The sling method consists of the following steps:
  * Place the trousers on top of the water as if they are to be put on.
  * Grasp the waistband, forming a circular opening on the surface of the water.
  * Maintaining hold of the waistband, cross the right arm over the left, then rotate the trousers counter
  clockwise above and behind the head.
  * Maintain the circular opening of the waistband with both hands.
  * Perform a large scissor kick while forcibly extending the arms overhead.
  * Sling the trousers quickly forward and downward, trapping air under the water.
  * Immediately gather in the waistband to maintain inflation of each trouser leg.
