What is smoke made of

It is also use to make carbonated drinks. The amount of water is important because it interacts with the other combustion products reducing the efficiency of the combustion process. It can also reduce visibility for a short distance. Carbon monoxide is an odorless and colorless gas that is highly toxic and regulated by EPA. Fairly high concentrations are produced but it is very light and is rapidly diluted in the open.

As a result, it is not a problem. Hydrocarbons and other organic compounds are not produce in sufficient quantities to be a problem. Particulate matter is complex mixture of small solid or tar liquid particles.

The size, shape, density and other physical properties are highly variable but the individual particles are too small to be seen with the naked eye. The small pieces of partially or unburned wood that fall out fairly rapidly are not included since they cause no visibility problem but they can become firebrands. These small particles can remain suspended in the atmosphere for long periods, even weeks. They drastically reduce visibility.

The small size also penetrates into the lungs, much the same as tobacco smoke, and can aggravate breathing problems such as emphysema. Particulate matter is the major problem with smoke due to the reduction in visibility. These small particles absorb and scatter light washing out the contrast. They can also act as nuclei for the formation of fog but there are generally enough material in the air already to act as nuclei.

The combustion process results in a rapid release of stored energy. The three broad phases are: pre-ignition, flaming, and residual smoldering. The amount and type of smoke produced will vary during each phase. Question: How does heat lift smoke? Fuel Loading If the amount of fuel that is consumed by fire is doubled and all other factors remain the same , the amount of smoke produced will generally double. However, there are many other physical and chemical factors of fuel that affect the amount of smoke.

Prescribed fire should burn off litter but not any of the humus. Protects soil and would produce more smoke. Fuel Moisture is the most important of all fuel factors. Dissolvable products are forms of smokeless tobacco that come in different shapes and sizes, such as lozenges, orbs, pellets, thin strips, and sticks.

Depending on the type, they are held in the mouth, chewed, or sucked until they dissolve. Like other tobacco products, dissolvable tobacco products contain nicotine and other harmful and potentially harmful chemicals.

These devices are not the same as e-cigarettes see below. Like other tobacco products, heated tobacco products give off nicotine and other harmful and potentially harmful chemicals. On average, smokeless tobacco products kill fewer people than cigarettes. But while they're often promoted as a less harmful alternative to smoking, some types have still been linked with cancer. To learn more, see Health Risks of Smokeless Tobacco.

E-cigarettes and other electronic nicotine delivery systems ENDS have become very popular in recent years, especially among younger people. They are sometimes used as substitutes for cigarettes or other tobacco products, but for many people, they are the first tobacco product used. Makers of e-cigarettes and other ENDS often claim the ingredients are safe.

But the aerosols mixtures of very small particles that these products produce can contain addictive nicotine, flavorings, and a variety of other chemicals, some known to be toxic or to cause cancer.

Depending on the house contents, the smoke generated can be extremely toxic or irritating. For example, burning plastics often produce soot and poisonous gases like carbon monoxide and hydrogen chloride. Another danger is that smoke contains flammable compounds. With increased oxygen, these can ignite either through open flames or by their own temperature.

This leads to a backdraught or flashover effect. Smoke also obscures visibility. This makes it difficult to evacuate from a fire. Smoke can often cause more damage to a building than flames or the heat of the fire. Smoke will leave widespread stains and smells that are difficult to remove.
