Smoke Alarms

Each year most people are in disbelief and doubt that something as critical as a fire could happen to them, this skepticism has led to more deaths and property damage than should have occurred. In the current generation smoke alarms are mandatory and advancements to the technology have been occurring rapidly. With the use of smoke detectors, firefighters have been more successful in the saving of lives and the protection of property. Even with smoke detectors getting more technologically advanced, researchers have still been looking into many more changes regarding smoke detectors audio alarm. The National Fire Protection Association also reports that homes with smoke detectors display significant differences than homes without smoke detectors. In 1930, a Swiss physicist named Walter Jaeger developed the first smoke detector by trying to develop an alarm to detect poisonous gases. Jaeger’s first attempt to detect the poisonous gases failed and he decided to take a break and have a cigarette. After the ignition of his cigarette, the smoke entered Jaegers device and it activated. Jaegers unintentional discovery of the smoke detector allowed room for advancement in fire alarm technology. Such advancement was in 1967, the first battery-powered smoke detector was created making it easily installed and replaced. In the 1960’s most businesses and public buildings had them equipped, and by 1969, the battery smoke detector received its first UL rating. During the 70’s, when awareness of residential detectors increased considerably, numerous programs started to hand out battery-powered smoke detectors. Due to this practice, deaths from residential fires decreased significantly. However, since the average battery-life is only one year long and most people neglected to change out their batteries, the death rate rose one year after these programs ended.

Chronic Fatigue Research Paper

...Senior Services and Chronic Fatigue According to the National Institute of Health, fatigue is a "common clinical complaint among older adults for which multiple definitions and measurement instruments exist. Fatigue is often a symptom of underlying medical or psychiatric illness." One of the greatest problems with chronic fatigue is that, while it is common, it is almost impossible to diagnose consistently. While the symptoms of fatigue typically include chronic tiredness and exhaustion, many seniors also complain of physical or cognitive decline or an inability to complete tasks. Measuring "tiredness", "decline", or slower performance is very difficult and relative, thus the complexity in diagnosing chronic fatigue. Many researchers have added "qualifiers" to help understand a senior's troubles. Examples are defining the condition as cognitive fatigue, muscular fatigue, or emotional fatigue. Further complicating matters, chronic fatigue syndrome is an ailment in which the symptoms of fatigue have no medical conditions to explain the problems. Yet, the fatigue could be caused by any number of medical problems including hypothyroidism, multiple sclerosis, heart disease, lung disease, or even rheumatoid arthritis or depression. Misdiagnosing the problem could lead to severe complications by missing an underlying condition. Many times seniors will have a hard time explaining the changes the are occurring. Senior services providers are often able to relate what they have seen...

Alarm Fatigue In Nursing

...When working in the hospital setting, every health care worker has been exposed to many different types of sounds. Whether it is cardiac monitors, phone calls, patient call-lights, bed alarms, feeding pumps, or IV medication machines, nurses are exposed to an extraordinary amount of noises while at work. Being exposed to constant sounds can become exhausting over a 12 hour shift, and many nurses can develop alarm fatigue. Alarm fatigue is when clinicians can become overwhelmed due to the sheer number of alarms and therefore become desensitized (Joint Commission, 2013). Regardless if every alarm that sounds needs a clinical intervention, if nurses develop alarm fatigue, it can be hazardous to their patient’s safety. With alarm fatigue,...

Smoking

...do some illegal things. For example, a couple of them smoked marijuana frequently, and constantly tried to pressure me into doing it as well. Additionally, they went to parties that often had alcohol; and they would drink as well. I offered them advice on several occasions that they should not be using these substances. When it comes to marijuana and alcohol, I am completely against it. I’ve never smoked or drank alcohol in my life, mostly because of religious reasons, even with all the pressure I received from some friends I had. It started to get more than I could handle when one of my friends invited some of us over to play some video games. Not even 20 minutes into being at his house, they began to pull out marijuana and started to smoke it, while I was in the room. I asked them to not do that right there, but they insisted on doing it there and then. So I left, and I am very glad I did. From that point on, I was stuck between remaining friends with these guys who I had known for quite some years, and putting up with their use of drugs around me, or saying so long and stop affiliating myself with them. So one of the most difficult decisions of my life, I had to completely cut off these friends from my life. At the time, I wanted to turn back, and find a way to resolve it, but I realized that I had already tried...

Mile High

...Zubura Zubura etting high on marijuana has been happening for Centuries.  Here we take a look at what we call the 3 Levels of HIGH on Cannabis.  We specify marijuana for obvious reasons. Once you have read these descriptions, we hope you'll agree and see (in your own experience) how we have come to these accurate conclusions. Below you will find our description of basically what happens when you smoke marijuana, and what happens when you continue to indulge.  Some believe there are more than 3 levels of getting high, and they have every reason as marijuana affects everyone a little differently. The apparatus you choose to smoke your pot in will vary.  While this can influence the rate at which you attain these levels, it does not negate the fact that you go through each one to experience the next (no matter ho ractice:
Limited to taking only two or possibly three hits (tokes, inhales, etc.)

  Effect: This is the first level experienced in getting high on pot. You catch a nice, calm, enjoyable, floaty, buzz.  First time users may claim to be stoned. This buzz practice is good for the daily user who begins their day with a buzz (not to be confused with "wake & bake" - see Stoned).  Catching a Buzz is not enough to get burnt out, and yet you have not truly reached the Level of High (so to speak).  You can revisit your joint or pipe later and refresh your buzz by taking a couple more hits.  This can be continued through-out the day with few (if any) ill effects.

The Importance of Fire Safety at Home

...The Importance Of Fire Safety At Home Fires can be devastating. They can tear apart families and destroy homes. The worst thing about fires at home and within business is that most of them are entirely preventable. Over 72% of the recorded fatalities from fires occur in the home. Every day, people start fires by falling asleep with cigarettes in their hands, leaving candles burning in unattended rooms and by leaving discarded items in front of open fireplaces. The fires that are started are careless and completely avoidable. Also, we can't forget fireworks. It can seem like a good idea to celebrate a happy occasion with fireworks or by setting off a glowing lantern. If you do decide to release any of these items, consider the following: Can you insure that you will not be endangering anyone around you? Do you have enough room to set it out, unobstructed into the night? Accidents are all too common where these items are concerned and you wouldn’t want to be responsible for any devastating consequences. Perhaps consider going to a staged event or an area away from the home to enjoy fireworks or glowing lanterns. Also in recent days, there have been stories of debilitating fires, that have destroyed homes and taken lives all across our region, even in the Oxon Hill area.  During October 2010, there was a fire in the Rosecroft Mews Apartment Complex, on the 2400 block of Corning Avenue in Fort Washington, MD, which is very close to the Oxon Hill/Fort Washington border...

Teenagers Behaviors

...Hallana Paula Barbosa Fundamentals of College Writing Dr. June E. Dunn E 103.10 Teenager’s behaviors The 1938 movie, Reefer Madness, suggests that teenagers who smoke marijuana are problematic to society. Since the early 1900s, drugs have been one of parents’ worst enemies. Marijuana changes a person both mentally and physically. According to reefermadness.org, the film was intended to be shown to parents as a morality tale attempting to teach them about the dangers of marijuana. The movie was revolving around the tragic events that happened when high school students tried marijuana. The curse of marijuana abuse is spreading across the United States of America like a disease and must be stopped. Parents are instructed to learn what they can about the evils of this addiction and warn their children against it. Dr. Carroll talks about the dangers for the horrified parents of the students at the school. He tells them that marijuana is more addictive than they imagine and that it could lead to violence and sexual misconduct. To illustrate his point, he tells the parents about a recent case they may have heard about, one which happened in their city, near their school. Three innocent young people are drawn in by the promise of a party. First Jimmy and Bill attend the party, followed by two exemplary students, and later, Jimmy’s sister and Bill’s girlfriend, Mary. Smoking the weed makes you laugh uncontrollably, dance wildly, and indulge in promiscuous sexual behaviors...

Fire Scienc

...dangerous and harmful. It is important to education each other as much as possibe to help prevent injries or deadly accidents. There are four stages that happen in every fire. Those stages are Incipient, Growth, Fully Developed, and Decay. Each stage plays a role in every fire. Understanding each stage, and how to handle or prevent it is critical in becoming in control of a fire. Flameovers and backdrafts are not consider stages, but also are definitely factors of a fire. These factors sometimes can be prevented. Some methods of prevention are taugh at fire academies, or fire schools, to new firefighters, and are constistly being developed. Incipient, also know as the "ignition" stage, is the first stage of a fire. In this stage smoke may began before the fire actually flames up. This is the stage where heat, oxygen, and a fuel source combine to ignite the fire. At this stage it can be controlled by a household fire extinguinsher. Growth is the second stage of a fire. With the initial flame used as a heat sourse, more flames flare up. Flaring up makes the size of the fire increase and the plume reaches the ceiling. In a room hot gases meet at the celing of the roomwhich cause all fuels in that room to be closer to its ignition temperature. In which the fire will eventually spread. During this growth stage is when a flashover can happen. Flashovers occur when a room or other areas becomes heated to the point where flames flashover the entire surface. Temperatures...

Marijuana

...Many people around the world smoke marijuana. Some people think it is right while others, like myself, think it is wrong. I believe that marijuana negatively affects teens, is dangerous, and costs way too much for what it is worth. The main ingredient of marijuana is THC, which quickly travels rom the lungs into the bloodstream, which carries the chemical to the organs and throughout the body. In about every high school 42% of teens have tried marijuana. When the teens smoke the marijuana it sends a chemical into the bloodstream that ends up going into the brain and makes the person act unusual. They lose concentration and are not motivated to do their schoolwork. Research’s show that students do not remember what they have learned while they are “high” on marijuana. This leads to them dropping out of high school. Teens are also affected by peer pressure from their peers to try marijuana. Most teens’ friends say, “smoke this and if you do not we are not friends,” so most of the time the teen will smoke it. After smoking the marijuana for a long period of time, the teen will become addicted. Students who smoke marijuana have twice the odds of being a dropout and have trouble finding jobs, getting involved in gangs and crime. Also, when teens smoke marijuana it usually leads them to trying heavier drugs. Marijuana leads to car accidents, fires, and murders. Research’s say that no one has died from the use of marijuana, but if the user of marijuana is driving he or she is most...
