swim class safety rulesGood swimmers often think they don't need a lifeguard.
Some are even offended at having to follow supposed safety rules.
If they have done dangerous things before and not been hurt
they are likely
to want to be able to continue the same fun things.
Diving into the big pool at De Anza, (the one 25 yards wide by 50 meters long) even in it's deepest (7 feet) part, is against rules laid down by the Dean of Physical Education (except for swim team members during practice or meets).
Studies tell us why someone would, for example, dive into a pool with a sign that said No Diving:
1) The familiarity effect; people who have done a lot of diving with no harm are less likely to comply with warnings. If your personal experience is that it has been safe for you, you gauge your future risk as low. Swim and Water Polo team members are among those most likely to ignore a warning sign.
This can be affected as well by never having known anyone who was paralyzed by a diving accident.
2) Younger people in general do not have as many life experiences that tell them that warning signs might be valid. The risk management part of your brain that says to you "that's not a good idea" does not fully develop until you are 20 to 25 years old.
3) People who are aware of a hazard decide they can minimize risk by trying to be safe. A diver knows that the water is shallow, but decides to try to attempt a dive with a shallow trajectory. Unfortunately, you have little control over dive angle.
4) Everybody else is doing it. If some people are diving where they should not it is more likely that others will as well, even with signs warning them not to.
5) Was the sign not seen, or not understandable, as in kids too young to read, older people with weakened cognitive abilities and people who do not read English well.
6) We see so many warning signs, yet we each rarely have a serious injury. People can become skeptical about warnings, especially since they have seen so many instances in the news of warnings that arise from litigation rather than a special care about people's safety.
7) Your internal reasons.
Some people are risk takers and are willing to risk the consequences. Disability and even death can result from a poorly done dive, but these results do not seem as likely to some people as to others.
Some people don't like to have their behavior limited by orders from the manufacturer of a product or the manager of a pool. Adults sometimes think their rights are being taken away by "too many rules."
Yosemite National Park Search and Rescue describes a couple of reasons they have to rescue people:
"Becoming complacent because nothing went wrong the last time you tried this stunt.
Thinking your skills in one environment (e.g. a strong swimmer in surf) will transfer to a new one (e.g. swiftwater)."
Diving boards seem to invite more risky behavior and have even been shut down completely at some pools.
These rules are common for diving boards and must be followed
in De Anza aquatics classes:
Only one bounce allowed on the diving board.
Only one person on the diving board at a time. This means people
should wait at the bottom of the ladder until the person
jumping or diving has done so, and should not approach the end
of the board until the swimmer is clear.
Don't run on the board or attempt to dive a long way through the air.
Swim away from the board immediately after diving so you aren't a hazard for the next diver and so you are safe if the next diver doesn't make certain the water is clear.
Jump or dive only from the end of the board. Don't use the guardrails for gymnastics. Trick dives only with permission.
NEVER perform a head-first entry, from the side of the pool or a diving board:
Over any hard device, such as a pole
Through inner tubes or hoops
Also note this memo from the Dean of Physical Education:
"Our swimming curriculum does allow for some diving instruction, however, effective immediately, this will occur only on the 1 meter boards. We will no longer use the 3 meter boards nor either of the towers for our activity classes. This would include jumping as well as head first entry. The Inter Collegiate divers will still have access to the 3 meter boards as long as the diving coach is present. If you are using the diving boards, please move enough lane lines out of the way to insure the safety of novice divers who may end up farther from the end of the board than experienced divers. My experience is that you should take out at least the first 3 lane lines in the diving well... Just a reminder, with the exception of the swimming teams, there is absolutely no head first entry allowed in the 50 meter pool. This would include the starting blocks in the 50 meter pool."
Later this was added: "In addition, the one meter boards are to be used only after following a progression of diving skills from the pool deck."
Goggles should not be worn to dive or to swim to a depth greater than 5 feet.
Kick boards can be dangerous used as toys. When a person tries to stand on, kneel on or sit on a kickboard and loses control of it, it can come to the surface with enough force to knock out teeth.
Almost all swim classes are fully enrolled and require lanes to be shared. For drills with two swimmers per lane people can swim side by side. In situations with more than two swimmers per lane (which is the case for most for most open rec swim), people need to circle swim. Each swimmer swims across the pool on the right hand side of the lane, turns and swims back on the right hand side. (Swim counterclockwise).
People who find themselves out of breath and needing to stop should do so by squeezing into the corner of the end of the lane at the pool deck. The same applies if you are doing sprints with long rest intervals. If you find that another swimmer behind you seems to be gaining on you, you can let them pass at that point. Ideally you would head for the left hand corner (as you approach) so others can do turns.
Ideally you would work in a lane with others of about the same speed and who are using the same 5 second or ten second intervals. Ideally you would all figure out how to be ten seconds apart from each other.
Hand paddles are too dangerous to use when sharing a lane.
I will describe how to clear your ears the first day of class. If it does not work you should immediately surface. If it does not work you should also have a doctor look in your ears to be sure you have not accumulated an excess of ear wax or have some other problem. You can lose your hearing if you ignore ear pain on submerging.
Don't hyperventilate (rapid, multiple deep breaths) before attempting to swim a distance. Many people think that hyperventilation can increase their oxygen stores but it does not. Instead it decreases your carbon dioxide levels in your bloodstream, the main clue that tells your brain you need to get a breath. You can pass out underwater, leading to inhalation of water, heart arrest and or heart damage and possibly death.
Floating idly in the pool can be quite relaxing. Feel the sunshine on your back, stare at the bottom. But out of courtesy to others, so your instructor, coach, a lifeguard or other swimmers won't wonder if you are capable of holding your breath for a long time or if you have really passed out, any person who wants to float without moving should signal that they are okay
by giving a 'thumbs-up' signal. Even if others at the pool you are at are not familiar with this courtesy, they should be able to understand it.
You should remove watches, jewelry and large body jewelry (piercings... eyebrow, ear, nose or wherever).
If it applies, also read body piercings and lifeguards:
Use waterproof sunscreen,
at least 30 SPF and a wide brimmed hat as often as possible. Read the bottle, does it need to be applied a half hour before you enter the water? If you apply it and then jump right in it won't work and you will make an oil slick.
Hypoxic training is a workout with limited breathing and therefore a limited intake of oxygen. No hypoxic training, attempts at swimming to the bottom of the diving well, distance underwater swims or other attempts at lengthy breath holding are allowed in my classes without permission and an instructor or lifeguard watching you.
Yes, anaerobic training can be effective to build fast twitch sprint muscles. But there is a big difference between
5 or 7 count breathing while training, limited to 25 meters or less, without hyperventilating first
and holding your breath for as long as you can.
Yes, people have tried having someone who wants to try to see how long they can hold their breath under water wave at the lifeguard as they do it. But when they stop waving is when they pass out.
The typical people who die from hypoxic training are competitive swimmers, Navy Seal divers, free divers or just good athletes. Since they don't seem like at-risk swimmers, lifeguards and coaches are less likely to pay attention to them.
From news releases, why you might want to make it a personal rule to not attempt prolonged breath holding even outside of a swim class:
"Stephen Praisner, a collegiate triathlete and experienced SCUBA diver, swimmer and lifeguard, died at the University of North Carolina at the age of 19 during a public swim in his university swimming pool. He was found in a lap lane in just 4 feet of water with his swimming goggles in place, the next day. His logbook indicated that he would be pushing his limits doing hypoxic training (competitive and repetitive breath-hold swimming) that evening."
from the St. Petersburg Times http://www.sptimes.com/2002/08/27/TampaBay/Eckerd_College_settle.shtml
published August 27, 2002
"Eckerd College has agreed to pay $1.55-million to settle a lawsuit by the family of a 15-year-old boy who drowned in the school's swimming pool in July 1999.
James Robert Goetsch III apparently blacked out while practicing holding his breath and floated lifelessly while other swimmers passed him by.
In a lawsuit alleging "reckless inattentiveness," Goetsch's family said the pool's lifeguard sat where she could not see the bottom of the pool, reading a magazine and socializing... the day after Goetsch drowned, another lifeguard was seen washing his car at the pool while on duty... Goetsch was in a lap lane of the pool with 15 to 20 other swimmers, practicing holding his breath to increase his lung capacity for snorkeling or scuba diving. But he apparently blacked out, police said.
Nobody immediately noticed anything wrong because Goetsch was known to hold his breath underwater.
An Eckerd College graduate who was swimming laps passed Goetsch several times in the lane.
She noticed on the third pass that he was on the pool bottom, about 3 1/2 feet below the surface, with his hands floating toward the surface.
In the lawsuit, the teenager's family said it took five to seven minutes to even begin to summon rescue personnel or administer CPR.
When police arrived at the college... Goetsch did not have a pulse and was not breathing."
"Omar Ortega, a nineteen year old member of the Mexican National Jr. and Senior Water Polo teams drowned during national team practice. The team, preparing for this summerís Pan American Games, was doing underwater swimming at the end of practice. Apparently, Ortega fainted and went unnoticed on the bottom of the 50 meter pool until it was too late to save his life."
January 18, 2009: A 15 year old high school freshman team member rescued her coach when he had challenged team members to see whether any of them could swim farther than him without coming up for air, but he passed out. He was on his third lap when she saw him suddenly twist and float toward the surface, but his head stayed underwater. Others thought he was faking it, but she looked closer. As she dragged him across the lane lines another coach dove in to help. It turns out they caught him in time to save him. A lifeguard started CPR and the coach began coughing and gasping for breath. He spent a night in the hospital.
A Navy Seal trying to get on the U.S. Free Diving Team got
permission from two lifeguards at a city pool to practice breath holding. The guards did not watch him. Several pool patrons approached the lifeguards and asked why a man was sitting on the bottom of the pool. A half hour after he submerged they finally investigated but it was too late. (See the end of this page for more about this incident.)
A 33-year-old military man drowned ... while
swimming laps underwater... The two Lifeguards sat
at a picnic table talking to one another. Several minutes later,
one of the lifeguards noticed the man lying motionless on the
bottom of the 5' section of the pool with bubbles coming
to the surface. The Lifeguard assumed he was okay
and decided to time him. After several additional minutes,
another patron alerted the Lifeguards to the fact that the
man wasn't moving and was in trouble. He was rescued, but it was again, too late.
When the responsible people are asked why they did not respond to the person on the bottom of the pool, they say they thought the body was a blemish, smudge or a towel, not a human being. In one case, the lifeguard said he thought the victim was walking on the bottom of the pool for exercise! Guards also don't expect people to be sitting at the bottom of the shallow water section of the pool with their backs to the wall holding their breath, as has been the case in some deaths.
If you stand at the edge of the De Anza pool and look straight down you can see that the pool gutter sticks out farther than the deck edge. If you decide to jump in you need to be certain that you jump out far enough from the edge that you don't hit your tailbone on the gutter. Unfortunately people don't always look before they leap into a pool and sometimes have jumped on a swimmer underwater near the pool edge.
Lane lines should be used only for temporary support.
Reasons to not hang on the lane lines:
1) they break
2) lifeguard might think you are in trouble
3) no room for people who really are in trouble
4) submerges it so it can't be seen
(especially important if it is a swim area boundary at a lake, for example).
This page does not have all the safety rules for the class, many will apply only to equipment we are using as we go along. It would be impossible to list all the rules, so pay attention to lectures on the subject.
Running on the deck or trying to push people into the pool are only a couple of the things that could cause injury. Think before you act in a
rowdy manner. No more holding on to the backstroke flags pole and spinning around it while trying to leap over a starting block. No more trying to catch something thrown to you while you jump of the diving board. No more cartwheels into the diving well.
In advanced classes we use ten pound weights for various tests. When they are taken from storage they should be carried one at a time by one person or two at a time, one in each hand, not in a stack by one person.
Immediately clear the pool at the first sound of thunder or sight of lightning, and do not use showers or a phone connected to a land line or your iPod. Wait 30 minutes after the sound of thunder before swimming again. "Our coach always lets us swim if the storm if far enough away" is not a valid excuse. If rain is heavy enough that we can't see the bottom of the pool, no one swims.
It is a violation of the health code to have a dog on the pool deck or in the pool.
People trying to learn racing dives should only do so in water at least nine feet deep, at De Anza that means only in the diving well.
Report any injuries and equipment or facilities problems immediately to your
In case we have an accident in class, the phone to call Campus Security at 5555 (non-emergency) or 911 (emergency) is on the wall behind the diving boards.
Also note this memo from the Dean of Physical Education:
"All able bodied individuals should NOT use the disabled door openers. If you are able bodied, you can certainly open the door yourself. This will save wear and tear on the door mechanism. This also includes the elevator. I see numerous able bodied students using the elevator to get down to the pool deck. Thanks for your cooperation."
Use the stairs to go from the bleachers to the pool deck, do not climb over the wall.
STOP THAT CRAMP! 4 causes -- and solutions -- for muscle cramps during exercise
swimmer's ear: http://www.mayoclinic.com/health/swimmers-ear/DS00473
from: Navy Seal Drowns in Shallow End of Honolulu Municipal Swimming Pool
"On March 26, 1998, a Navy Seal who was training for the U.S. Free Diving Team, approached the two Lifeguards on duty at a municipal swimming pool and explained he was training to hold his breath for a prolonged period of time while underwater in order to gain a spot on the U.S. Free Diving Team. The Lifeguards gave the individual permission to practice in the shallow end of the pool.
This individual then went to the shallow end, directly in front of the Lifeguard stand, went through a series of breathing and swimming exercises, then hyperventilated and attempted to hold his breath, while still located in the shallow end directly in front of the Lifeguard stand. In order to assist him in staying underwater, he draped a weight belt across his hips.
Meanwhile the Lifeguards, rather than being appropriately stationed in the elevated Lifeguard stands, both sat together under the tarp on deck-level bleachers on the opposite end of the pool. According to testimony provided by the Lifeguards, they lost sight of this individual, and several patrons approached the Lifeguards and asked by the man was laying on the bottom of the pool. Their reply was that he was practicing holding his breath.
Approximately 30 minutes after the individual submerged himself in the shallow end of the water, the Lifeguards investigated the potential incident and when they realized he was in trouble, they entered the water and removed him. Emergency resuscitation procedures were not effective because of the prolonged submersion time."
