You have something special you want to protect from the threat of fire. It consists of cement and aggregate, and the particular kinds of aggregate materials used can vary, as well as the amount used. Aggregate can make up 60 to 80 percent of the concrete's volume. The exact fire-resistance properties change depending on the type and amount of aggregate used. Natural aggregates tend not to perform as well.

Moisture in the aggregate can expand when heated, causing concrete to sinter after long exposure. Concrete is often listed as among the best fire-resistant roofing materials , too.

And you shouldn't overlook the roof as essential in fire-protection, since it's extremely vulnerable to sparks blown from wildland fire. Stucco is a plaster that has been used for centuries for both artistic and structural purposes. Modern stucco is made of Portland cement, sand and lime, and it serves as an excellent and durable fire-resistant finish material for buildings. It can cover any structural material, such as brick or wood. It usually consists of two or three coats over metal reinforcing mesh.

A one-inch 2. Roof eaves overhangs are a fire hazard, but they can be protected with an encasement of fire-resistant material. Stucco is often recommended as one of the best materials for boxing in hazardous eaves. Because of the versatility in finishing techniques, stucco can come in various colors and textures.

This means that it's easily adaptable to various architectural styles, including Prairie School, Mediterranean, Tudor and Southwestern. This way, you don't have to sacrifice beauty for practical fire-resistant protection.

Many structural materials will require underlying gypsum sheathing in order to achieve a good fire-resistant rating, and gypsum board is the most commonly used fire-resistant interior finish. Gypsum board, also known as drywall , consists of a layer of gypsum sandwiched between two sheets of paper. Type X gypsum board is specially treated with additives to further improve its fire-resistive qualities.

The paper on the exterior of the type X gypsum board burns slowly and doesn't contribute to fire spread. In addition, gypsum board has a noncombustible core that contains chemically combined water in calcium sulfate. When affected by fire, the first thing that happens is that this water comes out as steam. This effectively impedes the transfer of heat through the gypsum board.

The components of concrete — cement limestone, clay and gypsum and aggregate materials — are chemically inert and therefore virtually non-combustible. A house fire caused the white, cloudy appearance of this diamond left. Cardboard can cause a surge of fire that could injure anyone sitting or standing too close. According to the USDA Forest Service, cardboard also releases chemicals into the air from the ink printed on the boxes.

They release an irritant oil into the smoke and can cause big problems to you especially if you are allergic to them. Stainless steels are also selected for their oxidation resistance at high temperatures and their strength. This resistance depends, mainly, on the amount of chromium in the steel. Thus stainless steel is the best choice for fire safety and prevention when it comes to construction materials and life-cycle costs. Whilst there exists no completely fireproof plastic material, some plastics are inherently fire resistant.

However to satisfy the requirements of BS and similar fire testing standards, tests need to be done on specific fabricated components. Unlike wood, concrete does not burn.

Unlike steel, it does not soften and bend. Concrete does not break down until it is exposed to thousands of degrees Fahrenheit—far hotter than in the typical house fire. Yes, washing clothes in a washing machine WILL remove any flame retardants from clothing that you may have come in contact with throughout the day. Some animal studies have shown that long-term exposure to flame retardants can lead to cancer.

Researchers are also beginning to look at the potential association between flame retardants and other health outcomes, including thyroid disruption and obesity, and the role they may be playing in human development. Today, flame retardants are typically used in four major areas: electronics, building and construction materials, furnishings and transportation. Flame retardants can enable modern electronic equipment, like televisions and computers, to meet fire safety standards and can be vital to the safety of hundreds of these products.

Flame retardants used in a variety of building and construction materials in homes, offices and public buildings, including schools and hospitals, can provide increased fire safety protection. The addition of flame retardants to the material fillings and fibers used in furnishings helps provide individuals with an extra layer of fire protection and can increase critical escape time in case of a fire.

From airplanes to cars to trains, flame retardants can play a key role in protecting travelers from the devastation of fire. After the July Asiana Airline crash in San Francisco, for example, experts credited flame retardant materials with helping passengers survive the crash.

Materials and products that need to be fire-resistant can be chemically and physically different, and have different uses requiring the need for a variety of flame retardants. Chlorine and bromine are examples of halogenated flame retardants. Halogenated flame retardants have one carbon atom bound to a halogen atom and are used to protect many types of plastics and textiles.

Tetrabromobisphenol-A TBBPA is a halogenated flame retardant used as a raw material to manufacture printed circuit boards. It is also used in the plastic casings that surround electrical and electronic components. Phosphorus flame retardants PFRs Phosphorus is used to produce liquid and solid organic or inorganic flame retardants.

These types of flame retardants are extensively used in polyurethane foams to make fire resistant furniture, mattresses, and thermal insulation materials. Phosphorous is commonly used in fire resistant coatings and flexible polyvinyl chloride PVC.
