Problem: Write an article based on this summary: Be aware of the risks of using hydrogen peroxide. Swish with a hydrogen peroxide mouthwash. Make a hydrogen peroxide and baking soda paste. Prevent staining if possible.

Answer: There is conflicting consensus about the use of hydrogen peroxide in non-commercial products to whiten teeth. Using non-tested mixtures with hydrogen peroxide on your teeth can cause oral sensitivity and other abnormalities on your gums.  Talk to your dentist before you try whitening your teeth with hydrogen peroxide or any mixtures with it.  Be aware that while these natural methods may be less expensive, they could cause damage that is expensive to correct. Recognize that these solutions only clean surface stains and may not be as effective as commercially available hydrogen peroxide products. Make sure to use the lowest concentration hydrogen peroxide possible to help protect your gums and oral cavity. There is some evidence that rinsing with a hydrogen peroxide and water mouthwash can be safe when used over a longer period of time. It may also whiten your teeth and help prevent stains. Swish a mixture in your mouth daily to help whiten your teeth and ward off bacteria.  Use 2–3.5% hydrogen peroxide, which you can get at your local pharmacy. Using anything higher in your mouth cavity can be dangerous.  Pour 1 cup of the peroxide into a cup and mix it with 1 cup of distilled water.  Swish around your mouth for 30 seconds to a minute. Spit out the solution when you’re finished or if the solutions hurts. Rinse your mouth with water. Avoid swallowing the mouthwash, which could cause health problems.  Consider buying a commercially available mouthwash with hydrogen peroxide. Using a paste of hydrogen peroxide and baking soda can whiten your teeth and soothe sore gums. Brush with the paste daily or use it a couple of times a week like a mask.  Make sure you’re using 2–3.5% hydrogen peroxide. Put a couple of teaspoons of baking soda into a dish. Add a small amount of the peroxide and mix it with the baking soda. Keep adding a small amount of peroxide until you have a thick-ish paste. Brush the paste onto your teeth in small, circular motions for two minutes. You can also apply it with your fingertips to stimulate your gums.  Brush with the paste for a couple of minutes or leave it on your teeth for a few minutes for best results.  Rinse the solution off of your teeth by swishing with water from the bathroom sink. Rinse the paste off of your teeth. In addition to using your natural products, avoid anything that might stain your teeth if you can. Brushing or rinsing right after you consume them may help reduce staining.Things that can stain your teeth or make them more prone to staining are:  Coffee, tea, red wine  White wine and clear sodas, which can make your teeth more prone to staining Berries such as blueberries, blackberries, strawberries, and raspberries.


Problem: Write an article based on this summary: Purchase a new ignition lock assembly. Remove the cover over the ignition. Use an Allen wrench to release the ignition assembly. Make sure the new ignition switch is well-greased. Ensure that the internal lock pins can move freely. Slide the cylinder into place and reconnect the switch plug. Start the engine to ensure the steering wheel lock disengages.

Answer: Ignition assemblies are easily replaced in most vehicles and can be done at home by most hobby mechanics. Before getting started, you will need to order a replacement assembly from your local auto parts store. Be sure to give them the exact year, make and model of your vehicle to get the correct replacement part. Purchase a new ignition lock assembly prior to the removal of a failed assembly. Compare the two and verify the replacement is an identical match before attempting reinstallation. Generally, most vehicles have a split-plastic housing that covers the steering column and ignition lock assembly. Remove this plastic cover by first adjusting the tilt-wheel to its lowest position and then removing the fasteners holding the cover in place.  In some vehicles, the cover will include the portion above and below the steering wheel, while in others the ignition cover will be separate.  If it's not equipped with an adjustable steering column, remove the steering column support brace under the dashboard and allow the column to hang. Remove the fasteners from the column cover, separate the two halves and remove the plastic. Identify the ignition assembly and remove any trim components that prevent access to the ignition wire harness connector and tumbler release hole. Insert a 9/32” Allen wrench into the release hole while turning the ignition key backward.  Use the ignition key to pull the entire assembly out by pulling it toward the passenger side of the car. Take care to unplug the ignition switch wire connector as you remove the ignition cylinder. Once the ignition assembly is removed, compare the new switch and ensure they match. New ignition switches come pre-lubed from the factory ready to install. Verify the presence of grease on all external moving parts and ensure the new key fits and that the cylinder rotates smoothly in both directions.  If the ignition cylinder is not properly greased, apply liquid graphite or similar grease to the cylinder. Purchase grease at your local auto parts store if necessary. You can make sure the internal lock pins move properly by inserting the key completely in and out of the keyhole several times. The key should not get caught or stuck on its way into our out of the key hole.  Sticking lock pins are lubricated using powdered graphite that is applied directly inside the keyhole. Graphite comes in small tubes designed to “squirt” the powder with enough force to reach the back of any keyhole. It can be added when needed. When satisfied the new assembly matches the old one and is properly lubricated, slide the cylinder into position and make sure it is locked in place. Reconnect the switch plug and reinstall any trim components previously removed.  Rotate the cylinder forward using the key until you head it click into place. Be sure to plug the ignition wire switch into the new cylinder before sliding it into place. Before securing the steering column (if disconnected) and plastic cover, check to make sure the engine will start and steering wheel lock will /disengage. Do so by inserting the key and turning it while applying pressure to the wheel in the opposite direction of the lock pin.  Steering column bolts usually have torque specifications which are located in the vehicle's repair manual, in the specification section. If no torque specs are found, tighten bolts firmly using a long handled ratchet for leverage.  Column bolts must be secure to ensure they don't vibrate loose while driving.


Problem: Write an article based on this summary: Recognize the symptoms. Understand predisposing factors. Know the risks associated with your particular profession.

Answer:
Symptoms of work-related skin disorder can be varied, as varied as the causes themselves.  In general, the hands, fingers, wrists, forearms, forehead, face, and V of the neck (or any place on the body in which skin may have come in direct contact or the dust or fumes of an allergen) are the most at risk of developing contact dermatitis, so look for symptoms on these areas first. Most often the symptoms will be isolated to a specific area of the skin. Symptoms may be immediate, or they may linger for a few days. Look for symptoms such as the following:  Rash. Itching. Swelling. Bumps or blisters, sometimes filled with clear fluid. Hot or tender skin. Lesions. Burns. Skin discoloration. There are several predisposing factors that may make one more susceptible to work-related skin disease.   Age.  In general, younger workers are more inexperienced and more likely to take risks on the job site, which leaves them more prone to come into contact with harmful pathogens on the job site.  Skin type.  In general, lighter skin color is more susceptible to pathogens on the job site than a darker skin color.  Pre-existing conditions.  Pre-existing conditions may weaken your bodies immune system against unwanted pathogens.  In addition, employees with chronic skin conditions (such as acne or rosacea) are more likely to develop skin reactions.  Extreme temperatures and humidity.  Very low or high humidity and extreme heat or cold can cause chapping and dryness of the skin, thus weakening your skin’s natural barriers against pathogens.  Working conditions.  A clean workplace is less likely to be contaminated with toxic or allergenic chemicals. In some industries, working conditions may expose you to chemicals, such as agriculture, mining, and manufacturing. Because work-related skin diseases are varied, each occupation carries its own risk.  For example, medical professionals are more likely to develop immediate skin reactions from harmful agents such as radiation or solvents, and less likely to develop skin reactions that can take a long time to develop, such as exposure to sunlight or heat.  Know the particular causes and risks associated with your profession, and the accompanying symptoms. For example, wearing rings is not advised for employees in so-called “wet work” (work that involves extensive exposure to moisture) because water and soap can collect under the rings and become a breeding ground for bacterial and fungal infections.
