Article: There's some truth to the old adage that dogs and other animals can "sense fear". If you become agitated and run or scream, you may make the dog feel more confident in his attack, or, worse, you may appear threatening to the dog. Neither of these is a good situation to be in. When a dog approaches, stand completely still with your hands at your sides, like a tree, and avert your eyes. In many cases the dog will lose interest and walk away if you ignore him.  Do not wave your arms around or kick with your legs; the dog may perceive these actions as threatening. Don't make eye contact, since that could also cause the dog to lunge. Stand sideways to the dog and keep him in your peripheral vision instead of facing him and making eye contact. This will signal to the dog that you are not a threat. Don't open your hands and arms up to a bite by extending them. Keep your fingers curled into fists to avoid getting them bitten.  The dog may come quite close, even sniffing you, without actually biting. Running away can awaken the dog's prey instinct to chase and catch animals. He may pursue you vigorously even if his initial intent was just playful.  Additionally, you won't be able to outrun most dogs if you're on foot. Even if you are on a bicycle, many dogs will be able to catch up to you. If the dog continues to threaten you, offer him something to chew on, such as your backpack or water bottle: anything but your arm or leg. This may distract him enough to give you time to escape. You may want to carry treats or toys when traveling in areas known to be home to dangerous dogs. If approached by an angry dog, throw your treats or toy away from you. The dog may go after these instead of you.
Question: What is a summary of what this article is about?
Do not panic. Make yourself rigid and motionless. Do not try to run away. Distract the dog with another object.

Problem: Article: Sodium bisulfate is an acid that is sold in granular or powdered form. It has the advantage of being a bit safer and gentler than muriatic acid. Sodium bisulfate for pools is available at most home and pool supply stores. Different manufacturers may provide different instructions for use. In some cases, it may be necessary to dissolve the sodium bisulfate in water before adding it to the pool, while other products may be added directly to the pool water in powdered form. Follow the manufacturer’s instructions to figure out the correct amount of sodium bisulfate based on your pool’s size and the current pH of your water. You may wish to use ¾ of the recommended amount in order to avoid lowering the pH of your pool too much. You can also use a pool calculator, such as this one: http://poolcalculator.com/. Sodium bisulfate is relatively gentle, but it can still cause serious burns and irritation. Wear gloves and clothing that covers your skin, such as a long-sleeved shirt and long pants. Always work in a well-ventilated area. If you are concerned about the wind blowing acid granules into your face, wear protective goggles or a face shield.  If you get sodium bisulfate on your skin, wash thoroughly with soap and water. Go to the doctor if you experience skin irritation that doesn’t go away after washing. If you get any sodium bisulfate in your eyes, rinse with cold water for at least 15 minutes and then get medical attention. If you swallow any of the powder, rinse your mouth out with water and drink at least one tall glass of water. Seek medical attention immediately. With the pump running and the jets on, slowly add the acid to the pool water directly over the return jets. Take care to keep the powder away from the skimmer. Get close to the water when you pour, and take care not to let the wind blow any of the powder back onto you. Give the acid at least 4 hours to circulate, then test again. Since sodium bisulfate can also decrease your pool’s total alkalinity, it is important to test that as well and make sure it is still within an acceptable range. Make any necessary adjustments based on the results of the test. Don’t wait longer than 24 hours after adding the dry acid before re-testing your pool’s pH levels. If your pool’s total alkalinity level is too low after adding sodium bisulfate, raise it by adding an alkalinity increaser, such as baking soda or sodium sesquicarbonate, to the water. Alkalinity boosters for pool use are available in most pool and home supply stores.  Soda ash can also raise your pool’s alkalinity, but may cause the water’s pH to become too high again. Follow the manufacturer’s instructions to determine how much of any alkalinity booster to add to your pool based on the size of the pool and the current alkalinity level. If you are using plain baking soda, you can use a pool calculator, like this one: http://poolcalculator.com/. Although sodium bisulfate is relatively gentle, it can still irritate your skin and eyes. Give the acid plenty of time to dissolve and circulate throughout the pool before you jump in.
Summary: Buy sodium bisulfate or “dry acid” for the pool. Follow the instructions on the package. Determine how much sodium bisulfate to add. Use safety precautions. Pour the dry acid into the pool over the return jets. Wait a few hours and re-test your pool’s pH. Add an alkalinity booster, if necessary. Wait at least 4 hours before swimming.

In order to conduct effective training sessions, you need to keep in mind the objectives of your business or organization. These goals should guide you as you develop your training plan. For example, if the main goal of your business is to increase sales of medical supplies, you'll want to make sure to convey that to your trainees.  If your company has a mission or vision statement, use that to guide you as you develop your training goals. You want the training goals to be compatible with the overall objectives of your company. Be aware of what you want to accomplish. For instance, the purpose of the training may be to prepare employees for emergencies, improve business offerings or protect the privacy of clients. Make it clear to your trainees that there will be tangible benefits that each will gain by completing the training. Perhaps your trainee will earn a new certification that qualifies her for more responsibility. Or maybe there is greater job security for those who have completed training. Whatever the case, convey these benefits at the outset of training.  Outline the skills, information, and certifications that participants will gain by undergoing the training. These might include mastery of specific software applications, detailed knowledge of company policies and procedures, or enhanced customer service skills. Include in your plan the specific outcomes you want the training to achieve. Be as clear as possible. These should be more specific than the overall goals of the training. For example, you could say, "At the end of training, we will have 25 new employees ready to begin their first week of work in the Accounting Department at XYZ". If possible, note the benefits of achieving these goals. You might note, "Once these new employees are trained we will have X number more hours of production each week, which should increase our overall profits by X%."
