Lifeguard Systems Sample recommended minimum equipment and safety guidelines for standard operating procedures: limited visibility ops.

  • A minimum operation consists of a trained team of:
    • one primary diver,
    • one primary tender (who can serve as the Incident Commander),
    • one fully-dressed back up diver
    • one back up tender (who also serves as profiler),
    • and one 90%-ready diver.
  • Minimum equipment:
    • full exposure drysuit with attached dry hood, booties, and gloves for contaminated or cold water,
    • BCD with power inflator and a minimum of 30 lbs of lift,
    • three cutting tools (with at least two shears or wire cutters) in the golden triangle area, nothing on the legs,
    • regulator with analog gauges (depth, pressure, time), or if high visibility than digital gauges are acceptable,
    • pony bottle with quick release harness/holder
    • downstream pony regulator with exhaust-tee removed, secured in the golden triangle chest area with a quick-release connection and a protective mud mouthpiece cover,
    • downstream, balanced primary regulator, with environmental protection recommended for cold water
    • fins,
    • a minimum of a 3000 psi rated 80 cuft tank with a minimum of 2800 psi,
    • if a weight belt is worn with a standard buckle the release should be right-handed and the free webbing beyond the buckle should be 10-12 inches in length, the belt should not be obstructed from quick-release by the buoyancy compensator or any other piece of equipment; IW (integrated weights) are strongly not recommended. If IW are used, then place half the weight on a weight belt.
    • a positive-pressure full face mask or full head dress as needed for contaminated water, with a standard mask in the BCD pocket,
    • a full face mask block with a quick-release connection to the pony bottle is recommended for contaminated or cold water,
    • a chest diving harness for tethered diving,
    • distance-marked tether line (3/8” floating line) for tethered diving
    • locking carabiners
    • tenders wear appropriate personal flotation devices, protection equipment, and gloves.
  • Maximum diving depth of 50 feet with a possible additional ten-foot extension as dictated by the Officer in Charge
  • Maximum diving time of 20 minutes with a possible five-minute extension as dictated by the Officer in Charge.
  • Minimum air to be back on shore/boat is 1000 psi in an 80-cuft cylinder.
  • The maximum distance out on a tether line is 125 feet.
  • The maximum current for a shore based operation is .5 knots, the maximum current for divers not trained and certified as moving water divers, is 1. 5 knots.
  • The following minimum information should be logged for every subsurface operation in each diver’s logbook:
    • total psi used,
    • total time diving and total in-water time
    • blood pressure before and after dive
    • depth, current, other conditions
    • surface air consumption rate
    • respirations per minute (recorded every 5 minutes)
    • weight, suit, cylinder used
    • tender name, signature
  • Any diver has the right to say “no” to any operation for any reason at any time
  • Rescue time is anything up to 70 minutes from the time of the call.
  • Risk/Benefit analysis must be done prior to making plan of action.
  • The profiler documents on the profile map, every movement of the diver and log book information.
  • Divers must maintain a log showing a minimum of ten openwater dives annually, preferably in local conditions during drills or training. Tenders and divers must serve as both primary and back up tenders a minimum of six times each annually.
  • Divers and tenders must have certification from training for the job at hand (i.e. underwater vehicle extrication, ice diving rescue/recovery, drysuit and full face mask, moving water, evidence handling, etc.) and must attend a training program at least once every two years, in addition to drills.
  • A minimum of 6 drills or training sessions annually, with 12 sessions preferred
  • Post-operation, divers and tenders are responsible for making sure the scene is safe to leave, and all equipment is cleaned, checked, and properly stored.
