I'm a Fish!
I wrote this a year ago for something else. I edited it a little at the bottom but this kind of describes our job.

Marginal Duties: (These duties include, but are not limited to the following.)

Diving and Water Rescue/Recovery as it applies to law enforcement.

The Kootenai County Dive Rescue/Recovery Team is responsible for all water related accidents or incidents where one or more victims sink after failing to remain on the surface of the water. The team conducts underwater accident and criminal investigations. The team makes recoveries of a wide variety of items both small and large. As an example, those items can range from a piece of jewelry to a cruise boat.

To become a PSD (Public Safety Diver) the certification requirements are much higher than a civilian SCUBA diver. The PSD is closer to a Commercial or Military Diver than it is to Civilian Sport Diving. PSD certifications, unlike civilian certifications, must be renewed annually to every three years. Some of these certifications can be done as a team while others are done at the PSD’s own expense and on personal time. Physical fitness must also be tested annually to ensure a high degree of fitness. To maintain a proper level of fitness requires a lot of personal time.

The PSD is at much greater risk for an accident than the Civilian, Commercial or Military Diver. Several PSD’s die every year in accidents that were work related. The percentage of death’s and injuries for the PSD is much greater than SAWT (Special Weapons and Tactics) or other teams of a similar nature. This is not just speculation but from published national statistics.

One of the many reasons for so many accidents is the nature of the dive itself. In most every type of diving there is a saying that insures a great deal of safety. It is simply to, “Plan your dive and dive your plan”. This is impossible to do as a PSD. One can’t plan on when, where or how a rescue will occur and they never happen during ideal conditions. Like many other teams the PSD is on call and with a pager 24 hours a day, 7 days a week, 365 days a year in all weather conditions.

There are times where we have gotten up from a Christmas dinner, leave a movie theater in mid movie, leave a loaded grocery cart in the isle or even leave a child’s ball game or school play to respond to a call to possibly save a life while risking ours.

Quite often we are at home in bed sound asleep. The pager goes off directing us to a location with a brief description of the accident. Within two to three minutes we are up, dressed and out the door to the patrol car. Within seconds we are driving to the location with lights and siren while trying to get a diving game plan going in your head. All this while still insuring the public’s safety.

We get on scene of the dive and have to be briefed on what has happened. While that briefing is going on we are in the process of getting into our dive gear. We have to have a better knowledge of our equipment than any other style of diving. We can’t stop and think about what goes where it has to be instinctive. In other styles of diving this could prove fatal for the diver.

Once that briefing has given us the information we need and a second diver is on scene we hit the water and begin a search for a possible victim(s). All this has taken place in three minutes or less from our time of arrival on scene.

Most of our rescues occur at night. Using artificial lights we proceed into the depths of an environment that is much more hostile than Outer Space. Incase you didn’t know, man has walked on the moon several times while man has never been to the deepest depths of the ocean. An attempt was made way back in the 60’s to reach the bottom of the ocean but didn’t quite do it. Even with all the modern technology of today’s society it hasn’t been accomplished.

Once on the bottom we have to locate a target, which in many cases is a motor vehicle. Chances of it being damaged with sharp jagged metal are a real possibility because to get to where it is involves an accident.

Getting into a vehicle, with all the extra diving gear we are wearing creates other hazards. Entanglement, getting cut, getting trapped from an unstable vehicle moving off a steep bank and chemicals in the water are among a few of the hazards. All this needs to be done in low to zero visibility.

Once inside a submerged vehicle one or more victims might need to be removed and returned to the surface. If we are within the “Golden Hour” (for us it’s two hours) where we have a chance at saving a person’s life the trip to the surface is quick and direct, which puts the diver at great risk for Decompression Sickness, more commonly known as the “Bends”. If there is more than one victim and multiple trips have to be made, each trip compounds the danger the diver is exposed to. Each trip the diver makes should involve at least a 3-minute “Safety Stop” at 15 feet to off gas some of the dissolved nitrogen the body has absorbed during the dive. During a rescue the Safety Stop is not done as it cuts into the precious Golden Hour the victim has.

Rescue diving breaks almost every safety rule there is for sport diving. So a strong more rigorous training schedule is needed to ensure the divers safety. The PSD must have a greater knowledge of their equipment and how it functions more than any other type of diving. The lack of knowledge and training leads to fatal accidents with this assignment. The PSD must also be versed and knowledgeable in water related medical problems and how to treat and handle the situations

Recovery Diving for the PSD is quite different from Rescue Diving.

Speed is normally not an issue so there is time to plan a dive tailored to the job at hand. The style of diving we will use depends on visibility and the size of the item we are looking for. Should it require us to search close to the bottom or even into the muddy bottom fish hooks and fishing line are a real life-threatening problem. Some modern day fishing lines are very strong and can’t be cut with a knife. Getting tangled up in them can be a serious problem for the diver and these lines are in common use today.

Finding and recovering a body creates it’s own hazards to the diver. Even a fresh body will leak internal fluids into the water that will get on the diver. Some heavier mucus like fluids and vomit will actually stick to the diver and get into the equipment creating a Biohazard that will have to be cleaned off later. Older bodies that are in an advanced state of decomposition will start falling apart when moved. Those pieces of tissue will be various sizes and will stick to the diver and equipment causing yet another Biohazard.

An emergency response dive team can’t pick anything associated with a dive other than if they are willing to dive or not. We operate on a risk vs benefit mind set but the PSD is always at a greater risk than any other type of diving. We go into water contaminated with raw human sewage, petroleum products, and human body fluids to mention a few. We willingly put ourselves into a position to get entangled on the bottom by wire, rebar, power lines, water lines, vehicle and aircraft parts, going into sunken boats and hundreds if not thousands of other items.

We have to recover explosives and give them to the bomb squads to properly dispose of even though we have no bomb blast protection. We collect evidence that may be related to a crime. Improper handling of that evidence may lose a case for the prosecution. Proper handling of evidence is hard enough under normal conditions and those problems are compounded underwater.

We have been called several times to recover drugs thrown into a waterway by a fleeing suspect. These require special handling to preserve any evidence value they have that could lead to a successful prosecution.

Dealing with extreme temperature changes is almost normal. In the summer it isn’t unusual to have surface temperatures near 90 degrees while the bottom temperature is just above freezing. During the winter months the water can be near or at freezing temperatures and even have several inches of ice on the surface, which we must first cut through to gain access to the water.

Taking underwater photographs and video is totally different than land operation of the same cameras. It takes special equipment and knowledge to get satisfactory results.

Anyone who has ever handled sand bags knows what a tough job that can be. In the past we have been called upon to sand bag under water to stop leaks in sand bag walls. Should one of these walls fail with a diver under it the results could be in the death of that diver.

The divers are also called upon to go after suspects that have fled from law enforcement officers or fled from a crime and gone into the water in an attempt to escape. The dangers of this are beyond explanation, as we never know how a suspect will react when confronted knowing they are going to jail.

We do inspections of cruise boats, the docks, the floating green for the golf course which has it’s own set of unique hazards. We will inspect anything we are requested to so we can insure the safety of dignitaries and/or the general public.

We have had to shadow the Governor’s and their families for the Western States Governors conference held here locally. We have done this several times for several high-risk people and organizations in the past.

We work with and assist in the use of a Side Scan Sonar. This high tech system is deployed from a boat and towed close to the bottom of a body of water. It draws a digital image of the bottom and the items on it. It makes locating an item, such as a body, much faster, easier and safer than trying to dive a large area.

Working with the Side Scan Sonar unit is a surface monitored video camera system. Once a Sonar target is located the camera is deployed over the target to get a TV image to confirm what the target is.

Other areas of expertise related to PSD work is as follows: Line handling between the diver and a surface tender, a wide variety of boat and PWC handling, repelling both with and without full dive gear, snow mobile operation to access remote waterways, compass and GPS operation, DPV (Diver Propulsion Vehicle) operation, diver tow sleds, proper boat anchoring, first aid, CPR, EFR, use of a line gun, swift water rescue, dam inspection, 4X4 vehicle operation, trailer pulling and backing up into various hard to access areas, boat launching and loading, flood victim rescue, underwater metal detectors, compressor operation, filling tanks with compressed air, complete knowledge of diving computers, complete and thorough knowledge of diving tables both “No Decompression and Decompression”, underwater Crime Scene investigation and the collection and preservation of evidence.

A lot of people that are sport divers and switch to PSD work are amazed by the differences and the demands associated with it. Sadly though many will not return to sport diving after PSD work as they get a bad taste from what they have had to do underwater.

There is no way to predict the type of calls, the volume of calls, the location of the calls, the hazards involved or what time of the year the call load is going to be the heaviest. The entire business of being a PSD is in a world of unknowns full of hazards. The officer that chooses to become a PSD must face the fact that this will be a life changing and life risking occupation.

The last issue I would like to address is medical attention for a PSD involved in a diving accident. The closest help for a diving related accident in our area is in the Tri-Cities roughly 150 miles away. Should an accident happen the diver must be loaded onto an aircraft and flown as low as possible to the hospital. Should the pilot gain to much altitude the diver could die from complications of the problem he/she is originally suffering from being compounded by altitude. Hopefully the treatment facility is not occupied at the time of need or another facility will need to be located. Multiple victims can not be treated at a the same location unless that location has multiple Recompression Chambers or a multi-place Recompression Chamber.
