Problem: Write an article based on this summary: Never use a chemistry lab alone. Familiarize yourself with the layout before working. Never handle chemicals you are unfamiliar with. Follow the lab procedure carefully. Wash chemicals off of you immediately. Never eat or drink in the lab. Put everything back where you found it.

Answer: Using a buddy system in the lab is an important way to stay safe: if anything happens to you in the lab, someone is there who can help you or go for more help if needed. Ask a teacher, friend, or colleague to work with you in the lab as you are learning the ropes. If it's not possible to have someone with you in the lab, at the very least you should let people know that you are using it. Tell a friend or parent that you will call when you're done, and give them an expected time, so that they will know if you don't get in touch then something is wrong. Every chemistry lab is set up slightly different, which means that the things you need to stay safe may be hard to find in an emergency. Even if you are just helping someone else in a lab, you may need to locate safety gear in case they are incapacitated. Locate the following before doing any kind of work in a chemistry lab.  All exits to the lab (check to see if windows are locked, and unlock them if possible) Fire extinguisher and fire blankets Chemical shower Eye wash station First aid kit Telephone Chemicals can be harmless (such as water) or highly corrosive and dangerous (like sulfuric acid). If a chemical is unlabeled and you are not familiar with it, leave it alone until an instructor can tell you what to do.  Never sniff directly from a container with an unknown chemical. Some chemicals are highly toxic and can kill you if you inhale them. You can use one hand to "waft" the scent toward your nose from the top of an open container, rather than inhaling it. Similarly, never taste an unknown chemical. Doing so could be fatal. If you are in school, do not deviate from the lab procedure given to you by your instructor, such as by substituting another chemical or adding them in inexact quantities. If your instructor wants you to make a deviation, do so only with her supervision. Every detail in a lab procedure matters, including which chemical to add to the other and in what order, the exact temperature to heat it to, amounts to measure, or any other details given. If you spill any amount of a chemical on yourself, wash yourself immediately with cool water. Depending on where you've spilled the chemicals, you may need to use an eye wash station, hand washing sink, or an emergency chemical shower. If you've spilled harsh or corrosive chemicals on your clothes, you may need to remove the clothing, or even strip naked if your clothes are saturated. Nobody wants to get naked in front of their lab colleagues, but it is better than living with burns on your skin! Similarly, you should not prepare food in the lab or store it there. Even if you are careful to keep the food away from contact with chemicals, your food may still become contaminated with chemical fumes. For the same reason, never smoke, chew gum, or apply cosmetics in a lab. When you finish a lab, you should leave it how you found it. That means replacing everything where it belongs or leaving it where your instructor prefers. A clean lab is a safer lab! Be sure to push your chair back in and close all cabinets and drawers before you leave, to ensure that the lab is safe for the next users.


Problem: Write an article based on this summary: Seek medical help if you recognize any severe symptoms. Watch for signs that occur a few days after delivery. Go to the hospital if you see these warning signs.

Answer: Acute PPH is often accompanied by signs of shock such as reduced blood pressure, tachycardia or low pulse rate, fever, rigors, and faintness or collapse. These are the most definite indications of a PPH, but also the most dangerous. They require immediate medical intervention. There are some less severe yet dangerous signs of a secondary PPH that tend to occur a few days after delivery. These include fever, abdominal pain, painful urination, general weakness, abdominal tenderness over the suprapubic area and adnexae. PPH is a medical emergency and requires immediate hospitalization and measures to stop the bleeding. Hence, it isn’t a condition that can be ignored. If you experience any of the following symptoms after delivery, contact your OB immediately, as you could be developing shock.  Low blood pressure Low pulse rate Oliguria or reduced urine Sudden and continuous vaginal bleeding or passing of large clots Fainting Rigors Fever Abdominal pain


Problem: Write an article based on this summary: Determine your skin type. Find an appropriate moisturizer. Consider seeing a dermatologist for a prescription, especially if you have chronic dry skin.

Answer:
You need to know this before before you can choose the right moisturizer. To figure out your skin type, first wash and dry your face and wait an hour. Then, note how dry or oily your skin is. A more detailed guide can be found here. Once you know your skin type, there are a few basic categories into which your skin will likely fall. Most skin will range from ‘oily’ to ‘dry,’ with ‘normal’ between the two. The other two main categories are ‘sensitive’ and ‘mature.’  Moisturizers for dry skin are generally petroleum or oil-based. Oily skin calls for a water-based moisturizer. It should also be noncomedogenic to prevent your pores from clogging. Normal skin also needs a water-based moisturizer, but one which contains some oils, though much less than dry skin needs. Sensitive skin needs a moisturizer with medicinal or soothing properties. Look for moisturizers with chamomile or aloe, but stay away from those with fragrances, dyes, or acids. For older mature skin, you should look for a petroleum-based moisturizer rich in oils. There are many moisturizers on the market designed for mature skin that contain ingredients to help reduce wrinkles as well.  Try out body butter for a natural, oil-based option. It is quite common for a person's skin to be a combination of skin type categories. Your dermatologist will be able to prescribe a moisturizer tailored to your skin's needs. They will also be able to recommend additional skin care practices.
