Swim to the surface as swiftly and securely as possible (if in deep water, swim in the direction of the current). Push off for a swift ascent to the surface. If you are unable to swim, try floating. To float, use your body’s inherent buoyancy. Lie on your back and put your arms over your head to increase your surface area. This will allow more air to fill your lungs and you will rise to the surface if you are not already there.
If you are far from shore and the scene is chaotic, it may be difficult or impossible to tell how deep the water is. Assume it is close to your maximum depth and plan accordingly. If you can’t swim, stay below the surface until help arrives. Even a few minutes too long could be fatal. Once you reach the shallows, try to get out of the way of oncoming traffic while waiting for assistance.
People have been rescued from bodies of water up to 30 feet deep. However, if you’re caught beneath a section of collapsed bridge or other structure, you might not be able to escape without a major effort. Seek refuge on an exposed piece of land rather than under a bridge or other structure. The weight of a vehicle can cause other structures to collapse. If this happens near you, go find shelter elsewhere.
After the floodwaters recede, follow all safety instructions given by authorities.
If you tumble down this dam, you risk dying and getting water in your head, but you could live since there is enough of water and a roaring torrent to keep you away from the rocks. The Outeniqua Dam near George, South Africa, is one of the largest timber dams in the world. It was built in 1913 by Native Americans as part of a government-sponsored irrigation program for land that would become part of the U.S. state of Oklahoma. The dam’s main purpose today is recreational fishing and water quality improvement. Its 160 feet high x 2040 feet long concrete wall provides lake-level swimming and other aquatic activities for many people living in the surrounding area.
The Winnebago Indian Reservation created the Outeniqua Dam because they did not have the money to pay for its construction. They asked the federal government to build it instead. The United States Bureau of Reclamation agreed to do so because it was useful property that would generate revenue for the agency.
In addition to being a vital source of irrigation and recreation for the region, the Outeniqua Dam serves as an important flood control structure. Water flows through several channels inside the dam before it reaches its ultimate destination in the Orange River about 15 miles away. The dam has withstood severe storms and earthquakes without significant damage.
Engage your glutes and raise your hips as high as possible. When lifting, make a straight line from your head to your knees. Hold for 2-3 seconds at the highest position, then drop to the floor. Do 20 repetitions on each side. Lie on your back with your knees bent and your feet hip-width apart. Bring your arms overhead and squeeze your shoulder blades together. Lift your head and shoulders off the mat while keeping your elbows close to your body. Bend your elbows and lower your torso toward the floor. Don’t let your chest touch the ground first; keep your chin up until your arms are fully extended. Reverse the movement to return to the starting position.
The bridge is one of the most effective full-body exercises because it works the muscles of the abdomen, back, and buttocks. The muscles that you use when doing a bridge are the same ones that are used during a sit-up, so this exercise is a great alternative if you’re having trouble doing many sit-ups due to knee or back problems.
By engaging your core while raising your legs, you work your rectus abdominis (the main muscle in your abdominal wall), as well as your hip flexors and erector spinae (the large muscles of your back). Because the bridge requires that you lift your body weight, it’s highly effective for building strong muscles and bones.
Additionally, by lowering yourself back down into a bridge position, you are working your abs again!
Maintain parallel thighs and inner feet. From your shoulders to your knees, your body should make a straight line. You can either lay your arms at your sides with your palms down, or clasp them together and extend them down the floor under you. Hold the position for 10 seconds to 1 minute. Then release and repeat the exercise as many times as you can.
The goal is to work on your balance while holding the position for as long as you can. So if you feel like you can hold it longer next time, go for it!
For best results, do this exercise before eating anything. That way, you’ll burn off some of those big calories you just ate!
Now, if you want to make sure you don’t lose your place while balancing, simply bend your elbows and rest your forearms on the floor. This will give your body something to maintain while keeping you balanced throughout the exercise.
As you can see, holding a bridge is not only beneficial for your back, but also for your core muscles. These muscles help keep you balanced, so making sure you work them keeps you from getting injured.
Also note that if you have shoulder problems, it might be best not to lift weights over your head. However, if you do have issues there, light weight training is still very good for you!
Diving off a bridge or cliff, or even simply watching someone dive, may be a thrilling experience. Unfortunately, both bridge and cliff leaping are risky pastimes, especially when jumping from a height of 20 yards or more. These behaviors have even been lethal in rare situations.
The first thing to understand is that although diving from a bridge or cliff may appear to be a simple act, there are in fact many factors involved in determining whether the jump will be safe or not. For example: the type of bridge being jumped over; its condition; weather conditions; etc. Also, knowing how to correctly execute a leap can make all the difference between life and death.
It is very dangerous to jump from a height because your body cannot absorb all the forces generated by hitting the ground. The force of gravity does most of the work against your body, causing serious injuries such as broken bones, traumatic brain injuries (TBI), and deaths.
Even if you land on your feet, you are still at risk because of the impact with the ground. The same forces that injure people jumping from heights also harm those who fall from bridges or cliffs. In addition to physical injuries, people have also died from mental anguish following a fatal jump.
Knowing this, it should come as no surprise that suicide is the number one cause of death for individuals under 35 years old.
