Q: The sublimation of dry ice to carbon dioxide will cause the container to expand and possibly explode.  Dry ice can cause a violent eruption if packed too tightly.  Some people have been brought up on felony criminal charges for purposely confining dry ice until it explodes, creating a dry ice "bomb." Don't store dry ice in metal or glass containers, as an explosion can create shrapnel which can cause cuts or other serious injuries. The carbon dioxide from the dry ice will gradually begin to replace oxygen and can cause suffocation if breathed exclusively. Air out storage areas that have previously housed dry ice before entering. Even though no one may be around, spills and other accidents can occur if not under strict supervision. Don't leave dry ice on tiled or solid surfaced counter tops as the extreme cold could crack it. You will likely freeze the water in the pipes and may even cause them to rupture. The extreme compactness of a pipe will also cause dry ice to expand quicker and may cause an explosion.
A: Do not store dry ice in a completely airtight container. Avoid keeping dry ice in cellars, basements, cars, or other poorly ventilated areas. Try not to leave dry ice unattended. Do not dispose of dry ice in the sewer, sink, toilet, or garbage disposal.

Article: Joining a professional association, such as the National Organization of Professional Organizers or the Institute for Challenging Disorganization, is a great way to learn more about the profession and start the important process of meeting people and networking.  Join the organizations' listservs for access to the knowledge of thousands of other professional organizers. Ask a lot of questions, attend gatherings and conferences, and be as active as you can within the association. Making a name for yourself there will give you credibility as you move forward with your career. As you get to know professional organizers, ask if you can assist with a project. This is a good way to prove yourself and learn more about professional organizing. Professional organizing associations offer in-person classes ranging from Intro to Professional Organizing to Transference of Organizational Skills to guide you forward in the beginning of your career.  Some associations offer teleclasses or webinars, which are conducted online. These are generally less expensive than in-person classes. Keep in mind that the classes offered by organizing associations don't necessarily result in a degree; rather, they are designed to educate and build confidence. Some companies offer training programs, with classes building toward a certification issued by that company. Some specialize in business organization, and others in personal organization. Be sure to conduct a lot of research before signing up for a training program. These programs can be expensive, and won't necessarily lead to more clients or a better career. It's important to make sure the training program you choose is recognized as a reputable program by other professional organizers.
Question: What is a summary of what this article is about?
Join a professional association of organizers. Get educated. Consider a training program.

Q: You may not be able to solve the situation--your mother is still going to be sick no matter what you do. However, you can be there for her. You can show up when you're needed. You can offer support and encouragement. It may not be dealing with the problem as you'd liked to do, but you will be doing something, which can help alleviate your feelings of uselessness. You can pray, meditate, or just take a few deep breaths, but whatever way, take a moment to calm yourself down. Accept that you do not have control over the situation. Your mother may be sick, but you can take the time you are spending with her to develop a better relationship with her than you've had in the past. Even if it doesn't change anything, it will help others realize that they aren't the only ones who are dealing with these feelings, which is a way you can provide support. It also opens up the discussion, so others have a chance to talk about their feelings, as well. Long-term stressful situations can lead to depression, and feeling useless could be a symptom of depression, especially if it is accompanied by other symptoms.  Symptoms of depression include having trouble focusing, feeling pessimistic, not being interested in things you usually enjoy, feeling guilty, being extra tired, being consistently sad, and even experiencing physical symptoms like headaches or stomach aches.  Feeling sad on occasion doesn't mean you’re depressed. Depression is a sustained period of not caring and feeling sad. When symptoms start to overrun your life, you may be depressed. If you are depressed, you may need medication, or you might need to seek out counseling to help you work through some issues, which may help alleviate your feelings of uselessness. Remember, being depressed is not a sign of weakness. It can be caused by a traumatic event in your life, but it could also be a chemical imbalance that needs to be corrected. Also, certain medications, your genes, and other problems like illnesses can also lead to depression.
A:
Do what you can. Take some time to stop and breathe. Focus on what's going well and make that a larger part of your life. Talk about what you're feeling with others in the situation. Check yourself for signs of depression. See a doctor if you suspect you are depressed.
