Stains, corrosion and scale are not just problems during the swimming season. By using the right products and following the simple procedures below, you will protect your pool during the cold winter weather. Climates vary, so be sure to ask your local pool dealer for specific winterizing instructions.

1. Take a water sample to your local swimming pool dealer for a complete water analysis. Follow your dealer’s instructions to balance the water as needed.
2. Clean your pool by brushing the walls, skimming the water surface and vacuuming the pool bottom. Clean pool wall tile and vinyl with cleaner. Empty pump an skimmer basket.
3. Clean or backwash the filter according to the manufacturer’s instructions using a filter cleaner and degreaser following the label instructions.
4. Protect your pool water by doing a pool shock. Run the pump for several hours to disperse the product thoroughly.
5. Protect your pool against algae with the addition of an algaecide.
6. Lower the water in the pool down to the level recommended by the manufacturer for winterizing.
7. Drain water from equipment such as pump, filter, heater, chlorinator, hoses and pipes as recommended by the manufacturer. Ask your dealer if you should protect the pipes and equipment with a non-toxic, swimming pool antifreeze. Ladders, chlorinator (if offline model), pump and skimmers baskets should be stored.
8. Cover the pool using a quality cover to prevent leaves, dirt and debris from accumulating in the pool.

After consulting with your local swimming pool dealer, you may decide to leave your pool open during the winter months. If so, the following are recommended at a minimum:

1. Operate the pump at least several hours a day or continuously if the temperature gets down to freezing.
2. Maintain normal pH and minimum free chlorine levels.
3. Keep the pool free of leaves, dirt and debris.

The key to learning how to delay ejaculation is to train your mind and body to perform as you wish it. There are many things you can do to master the art of ejaculating. The most vital thing is to simply know your body well and control it.

One

But first you have to know your body. Know what it can do and not do. Understand the signals it gives you and act on them. We all have different points that draw us up to the point of “No Return” Know your point, know what takes to get you there and learn to not reach that point so fast.

Two

When you are thinking you are going to have sex a good thing to do is to masturbate and before you ejaculate stop. Wait a few minutes and do it again. Train your body not to release until you are ready to release. Do not give in to the urge. When you feel the need hard and fast to cum then reach down with your strong hand and grab the base of your penis and squeeze hard.

Three

Learn the breathing routine. When you are close to releasing the ejaculate, take a deep breath through your nose, as deep as you can and hold it for at least five seconds and up to ten. Then slowly let it go through your mouth. Do this repeatedly until you are in control again.

Four

Change positions. There are so many positions that you can try. Do not be shy and just go for it. Slow down your strokes and breathe. Missionary style is NOT the best for controlling your ejaculations.

Five

Something you can try as a technique to train your body before having sex is the cold water treatment. Whenever you take a shower the last thing you do is to shower your genitals with cold water, icy cold is good. The idea behind this is the penis and the testicles need lower heat that is why they are outside of the body. This keeps the production of sperm at their best.

The goal of doing this, and you can alternate off during the say shower cold and hot, cold and hot, just make sure the last is cold. What this does is give your testicles a teasing work out. Where the cells and the muscles contract and expand, contract and expand repeatedly. A great work out don’t you think?

Ice skating is not all glamor and grace. There are also inherent dangers, and all ice skaters, especially the beginners, should be aware of these. In the year 2007 alone, 4,500 skaters were injured in Austria, requiring hospital care. Wrist and head injuries topped the list.

The Fall

Falling on ice is the first danger to be considered, whether skating indoors or outdoors. It not only depends on the skills of the ice skater, but also on the quality of the ice surface, as well the ice skates used. Serious and fatal injuries are very rare, though, but there are isolated cases of paralysis after falling on ice. The skate blades also present one potential cause of danger, as it is very sharp it can slice skin and cause injuries. This emphasizes the need to wear protective gear, especially helmets, for avoidance of head trauma or other similar injuries caused by falling on a skates metal blades.

Skating Outdoors

Moving and gliding on frozen waterways is still an observable fact. As natural ice is unpredictable in terms of strength and structure, there is a potential danger of falling into freezing water whenever the ice breaks. The fact that the ice conditions cannot be controlled should hinder skaters from trying to skate on frozen bodies of water. Once they fall, it will be very hard, if not impossible, to get back onto the ice or out of the water, as the ice tend to break in a continuous manner. This becomes even more hazardous when the skater has no company while skating on naturally-occurring rinks. In the depths of the freezing water, it will be very difficult to swim because of the skates and heavy winter clothing, so there is a big chance for the skater to drown or suffer from shock and hypothermia.

When skating outdoors, one has to remember that the ice is thinner, and therefore weaker, in areas near river or pond edges because of vegetation and higher temperature. Ice is also weak under bridges and areas with most sunlight exposure, also because of warmer temperature.

Because of these ice skating dangers, people need to be educated about wearing appropriate protective gear and, if possible, staying out of frozen waterways when skating, or, if they really want to, they need to know the thickness of the ice first before putting their skates on and starting to move on ice.

Everyone has heard of dehydrated foods. It’s the simplest and least-expensive way to store food for longer periods of time; it’s something that’s more affordable for families to do at home–if they can afford to spend the time preparing and dehydrating foods for emergency food storage. But what of freeze-dried foods? To some people the term may be completely new, or sound familiar but unsure of the definition. Some may have even tried freeze-dried food without even realizing they have. If you have had “astronaut ice cream” before, then you have tried freeze dried food.

When gathering food for emergency food storage, hiking, camping or other similar reasons, it is good to know the difference between these two types of prepared food storage. Not only will knowing the difference help you understand how they’re made, but help you know why some processes will be better for the types of food you wish to store versus other types of food.

Traditional food drying, or dehydration, has been around since ancient times for food preservation. Since the convenience of refrigerators weren’t around, the sun, wind and air had to do the drying. By removing the majority of water, enzymes and microorganisms are inhibited, stopping or severely slowing their usual routine of spoiling food.

Today, solar or electric food dryers can be bought for your personal home to provide more consistent results. With the cost of purchasing one, let alone the time it takes to prepare dehydrated food yourself, these reasons often steers people from that route. Fortunately, with improved technologies, the internet, and companies mass producing dehydrated foods, consumers can buy dehydrated food at affordable prices–not to mention save countless hours of dehydrating food yourself.

Freeze drying food has not been around too long, and when the concept was originally practiced, it wasn’t used for food. During World War II, certain medical supplies were spoiling before arriving to their destinations. Scientists determined that by freezing the materials at a certain point then drying to remove the formed crystals, it would preserve its state without refrigeration. While the process had to be modified for the sake of preserving the texture of food when freeze-drying, a faster freezing process is done to prevent crystallization from breaking the cell-walls of food.

Now understanding the big difference between the two methods of preserving food for emergency food storage, hiking or the many other reasons people buy dry food, which method is the best? As with almost all answers to broad questions, the answer is: “it depends.” Each process has its advantages, and when used correctly, can give consumers looking to purchase food storage the best options available.

Traditional dehydration is less expensive than freeze drying. Without the need of more expensive and sophisticated equipment, standard dehydration will produce preserved food at a cheaper price. Nevertheless, this process has more limitations, including the quality of some types of food’s texture and taste. Most dehydrated foods can have little to no seasonings or other ingredients. Once you rehydrate your food, usually more cooking can be required if it’s a full meal you desire. That’s why dehydration is better for simpler foods such as snacks, fruits, grains, etc.

Freeze drying, while more expensive, can open your world to many more possibilities for preserving food. Entire meals with full ingredients, seasoning, etc. can be freeze-dried together. Additionally, only water is needed to prepare your meal again, reducing the need for preparation. Still, with a higher expense, freeze drying may not always be the best answer every time.

The best result then for finding the right type of prepared food storage is finding preparers that use both methods. Many companies today prepare full pre-made meals for food storage, which include food that has been both dehydrated and freeze-dried, depending on the type. This allows all servings of food, be they freeze-dried meats, or dehydrated grains, suit you and your needs for food storage, camping, hiking, or whatever other reason you have for purchasing preserved foods.

Insulated bucket trucks were created in an effort to help protect workers from electrocution. This applies to linemen who may be working on utility lines such as telephone poles or transformers, etc. These jobs have the added danger of not only being located in high places, but working near extremely high voltage lines. This is why there was a need to create something that could additionally protect these workers and reduce the risk of electric shock.

There are three main aspects of an insulated bucket truck that can provide protection from electric shock. These are the most important components to maintain and keep within the standards as defined by ANSI:

Bucket Liner – This will protect the portion completely inside the liner, such as a person standing. Once the electricity touches the liners, it will become ineffective to anything inside the liner.

Upper Boom Insulating Section – This will prevent the flow of electricity from the boom tip through the boom elbow only.

Lower Boom Insert – This piece will provide a section of insulation between the elbow and the truck chassis.

A common misconception is that the rubber from your utility truck tires will provide shock protection. This is false as they were not built to provide electrical insulation. Dirt and salt that accrue in the tire tread can actually act as a conductor of electricity. Your body is an even better conductor of electricity, so you should never touch a bucket truck that is in contact with electrical lines even if you are operating with controls that are wooden. Here are some effects of an electrical current on the body:

Freezing Current – 5-25ma – can cause an involuntary muscle spasm

Knockout Current – 25-100ma – unconsciousness may occur and breathing could stop

Nerve Block Current – 100-200ma – your heart could stop and you would almost certainly need CPR

Frying Current – over 200ma – this will literally cook the part of the body that the current came in contact with. Death is almost always instantaneous if the path of the current is through the chest.

It’s a good idea to always keep these factors in mind when working near electricity. Additionally, you should consider the humidity of your current surroundings as well as atmospheric electricity such as lightning. You should never be working in a bucket truck, near power lines or not, if there is a lightning storm taking place.

Hopefully this article has helped you to better understand what an insulated bucket truck is and why workers can benefit from them. Keep in mind that you should only operate or use an insulated bucket truck if you have had approved training. It is not intended as a substitute for OSHA or ANSI standards, so, again, please make sure you have the proper training and certifications, where applicable, before use.
