Re-entry edit It is often necessary to writing install new electrical cables or mechanical systems through a hole in a fire-rated barrier which has been firestopped during construction. In this case, the firestops are "re-entered". To maintain a building's original fire-protection plan, firestop re-entries must comply with the certification listing upon which the original configuration was based. Reentry firestop mortar Opening created for future use in an electrical service room Spray fireproofing edit Improper firestopping Spray fireproofing of structural steel is best accomplished before interior partitions are built. Otherwise, a conflict with firestops in firewalls could result. Firestops must adhere to the bare, dry, unobstructed surfaces of the fire barrier which is penetrated (metal decking, for example or adjacent to an interface of two fire barriers at which fire stopping is required (such as beams). Spray fireproofing cannot be applied before firestopping on these surfaces, since the fireproofing would obstruct adherence of the firestop materials to the fire-barrier surfaces. Spraying the upper room perimeter with fireproofing may also cover wall or ceiling joints and through penetrations which require firestopping. These joints are then not provided with proper firestopping, violating the integrity of the passive fire barrier.
Junctions between fire-resistance-rated wall or floor hippie assemblies. Head-of-wall (HOW) joints, where non-load-bearing wall assemblies meet floor assemblies. Materials edit, components include intumescents, cementitious mortars, silicone, firestop pillows, mineral fibers, and rubber compounds. Pipe with metallic piping penetrations in a 2-hour fire-resistance rated concrete floor slab Inadequate firestop with rockwool Construction drawing of a firestop maintenance edit firestops should be maintained in accordance with listing and approval use and compliance. Construction documentation sometimes includes an inventory of all firestops in a building, with drawings indicating their location and certification listings. Using this, a building owner can meet the fire code relating to fire barriers. Improper repairs may otherwise result, which would violate the fire code and could allow a fire to travel between areas intended by code to be separated during a fire.
Please improve it by verifying the claims made and adding inline citations. Statements consisting only of original research should be removed. (August 2016 a firestop is a passive fire protection system made up of various components and used to seal openings and joints in a fire-resistance-rated wall or floor assembly. Penetrating cables are known as multi-cable transits (MCTs). Firestops are designed to fireproof a wall or floor assembly, impeding the spread of fire and smoke by blocking openings with fire-resistant materials. 1, contents, description edit, firestops prevent unprotected horizontal and vertical penetrations in a fire-resistance-rated wall or floor assembly, which can diminish the fire-resistance rating of these structures and are the leading cause of rapid, erratic spreading of smoke and fire. 1, opening types edit, firestops are used in: Electrical, mechanical, and structural penetrations, unpenetrated openings (such as openings for future use). Re-entries of existing firestops, control or sway joints in fire-resistance-rated wall or floor assemblies.

Our family all lost quite a bit of weight, as well: my mother lost fifteen pounds and my father lost more than twenty. Her doctor tells her that if she continues this lifestyle change, she will significantly reduce her chance writing of heart problems in the future. The second example not only contains more information, but it presents it in a believable and interesting way. By including specific details, the author appears to be an "expert so the evidence is more persuasive. Analysis, your analysis or concluding observation is your way of "wrapping up" the information presented in your paragraph. It should explain why the evidence supports your claim and why this supports the main thesis in your paper. Its important to end with your own analysis of the information rather than with evidence.
This keeps you "in control" of the paper; if you end with evidence, youre emphasizing ideas from your sources rather than your own. The reader relies on you to analyze the evidence in the paragraph and explain why it matters to the claim and to the rest of the paper. Here are some examples of weak and strong analysis/concluding observation sections: Analysis that is really evidence (weak experts at duke universitys School of Medicine agree that soy milk is a healthy choice. Analysis that doesnt relate evidence to claim and thesis statement (weak soy milk therefore prevents disease. Analysis that explains why evidence supports the claim and why this is important to the papers thesis (strong The disease-fighting and health-promoting components of soy milk have the potential to change peoples health and to improve their lives by affecting both cholesterol and weight. This makes soy milk an important factor in heart health, so people should consider switching to soy milk. This article possibly contains original research.
Some researchers even believe that soy may help to stimulate the metabolism (duke 4). Note that the second example seems more "balanced because the author demonstrates knowledge of the subject and incorporates several expert opinions to back up the claim. Sometimes your assignment will not require you to conduct research into secondary sources, and you may need to use your own ideas or experiences as evidence to back up your claims. Try to be very specific. If you include detailed examples and explanations, your evidence will be more interesting and more persuasive to the reader, and you will seem like more of an authority on your topic: evidence that isnt specific (weak evidence my mothers cholesterol was bad, and the doctor.
Our family started eating more soy and soy milk, and her levels eventually got much better. During this time, all of us also lost quite a bit of weight. Evidence that is specific (stronger evidence two years ago, my mothers ldl bad cholesterol level was 242, and her hdl good cholesterol was 37, so she was considered "high risk." Since she was hesitant to take cholesterol-lowering medications, her internist suggested that she try. He believed that it was worthwhile to try this before placing her on medications. In order to support her, our entire family started drinking soy milk and walking in the evenings. After six months, her ldl dropped to 198 and her hdl rose to 45, which was a dramatic improvement.

Since soy is a "low-glycemic index" food, it may help people trying to lose weight "feel more satisfied and less hungry until your next meal, which is beneficial for weight management and control" (1). Evidence that includes information from a variety of sources (stronger evidence scientists believe that soy milk has the potential to balance cholesterol levels in humans: "A diet with significant soy protein reduces Total Cholesterol, ldl cholesterol (the "bad" cholesterol) and triglycerides" (Tsang 1). Since twist soy milk is one of the easiest ways to incorporate soy into the diet, this is a good choice for people seeking to lower their ldl and triglycerides. Soy milk also may reduce the potential for heart disease. Asian countries, which traditionally consume more soy protein, have a much lower incidence of heart disease and many types of cancer (Berkeley 4). The benefits of soy arent just limited to the heart, however. Soy milk and cheese made from soy milk may help with weight loss since they contain less saturated fat than regular dairy products, although they contain about the same amounts of fat as reduced-fat milk and cheese (Collins 1).
In a paper that incorporates research from secondary sources, your evidence may include information essay from articles, books, electronic sources, or any of the research you gathered. The evidence may take the form of a direct"tion, paraphrased material, statistical data, or any other information from one of your sources that helps to support your claim. Try to incorporate information from several sources into each paragraph. Avoid just "retelling" the information from a single author or article. Aim to represent a variety of opinions and views. This way, youre not just telling the reader what one expert says, but youre explaining how your claim is supported by research from several experts in your field. Here are some examples of weak and strong evidence sections: evidence that includes information from one source (weak evidence according to collins, soy milk has more protein than cows milk, and doesnt contain the saturated fat or cholesterol (1). Soybeans are "complete protein" because they contain all eight amino acids (Collins 1). Collins points out that "as little as 25 mg of soy protein a day may decrease levels of ldl cholesterol and Triglycerides" (1) and this may reduce the chance of heart disease.
that cannot be disputed; the second example is stronger because it uses those facts to make an argument. As you can see, the second example not only tells the reader that soy contains healthy isoflavones and nutrients, but it also argues that these facts make soy milk a better choice. To evaluate whether your paper contains effective claims in each paragraph, read only the first sentence of each paragraph. You should be able to follow the development of the papers thesis by reading only the claim sentences. These should tell you the main points that you are making throughout the paper. Your claims will also prepare the reader for the second section of your paragraph. Evidence, this is how you support, or back up, your claims. The evidence will help to "prove" each claim to the reader.
If you get stuck developing these claims, try to think of reasons why your thesis is true. Each claim should be a reason why the reader should believe your papers main idea. For example, perhaps youre writing an essay about whether people should drink soy milk instead of cows milk. Your "reasons" for this might include health benefits, environmental benefits, cost-effectiveness, and safety, so you would focus one paragraph on each of these topics. One of the most common mistakes is to present a topic sentence that is actually an observation of facts or a description of events rather than an active argument. When you make a claim based on a fact or event in your topic sentence, you arent presenting an arguable claim that you can back up with your evidence in that paragraph. Here are some sample mattress claims for the "health benefits of soy" paragraph: Claim based on a fact or event (weak soy milk contains healthy isoflavones and nutrients.

Effective paragraphs are important in all types of writing. Your paragraphs guide your reader through the paper by helping to explain, substantiate, and support your thesis statement or argument. Each paragraph should discuss beauty one major point or idea. An effective paragraph has three parts: claim, evidence, and analysis. Claim, this is also sometimes called a topic sentence. This will be your way of announcing the main focus of your paragraph; it should tell the reader what your paragraph will be about. It may be helpful to think of your claims as mini arguments that support the papers main argument or thesis. Just as in the thesis statement, your topic sentences should be debatable. In other words, they should be arguable claims that you will try to "prove" with your evidence.
