Recent winter storms have resulted in several cases of families using charcoal indoors as a form of warming their homes, yet doing so can be dangerous and even fatal. Carbon monoxide (CO), an odorless and tasteless gas produced when burning charcoal or other combustibles indoors or in closed vehicles can become toxic quickly - it has even been known to kill before its victims realize the risk. For this reason alone it should never be done indoors or in vehicles!
Burning charcoal releases carbon dioxide (CO), water vapor and carbon monoxide into the atmosphere; both components combine with oxygen in the air to produce carbon monoxide poisoning, which is especially hazardous to children and elderly adults. Carbon monoxide poisoning symptoms include confusion, dizziness, headaches, weakness and unconsciousness - potentially fatal conditions for those exposed.
To produce charcoal, organic material that forms its core is carbonized by heating it at very high temperatures in the absence of oxygen, creating porous charcoal with many holes and pores to absorb various chemicals and purify water and air pollution. Charcoal can also be used to clean contaminated sewage systems and soil contaminated by pollution.
Charcoal can be made from virtually any dense and fibrous wood or plant material that produces enough density and fibrous structure, including hardwood lumber or plant matter such as bark. Lump charcoal typically made from hardwood lumber is called lumber charcoal while briquettes may come from sawdust or other by-products like bark paper cardboard or plant fibers. Either type produces little ash while providing excellent barbecuing heat with reduced emissions for fireplaces as well as campers tents or RVs.
There are also indoor-burnable charcoal products such as the popular briquettes that can be enjoyed without the need for open flame, like Taiwan, Korea and Greece for their low ash content and long burning hours (exceeding four). This form of charcoal is known to have many devotees as it offers both convenience and long burning hours (over 4).
To produce charcoal, the most popular method involves layering up desired raw materials in a metal drum and covering it with plastic sheet. Once covered, large rocks or bricks may be added on top for further heat retention; occasionally stirring may speed up this process before finally taking out of the drum and cooling before use. Some manufacturers now produce eco-friendly briquettes without binder - creating even less environmental waste!
