[1] Fire-retardant gels can also be slurries that are composed of a combination of water, starch, and clay. [2] Used as fire retardants, they can be used for structure protection and in direct-attack applications against wildfires. [3] [4] Fire-retardant gels are short-term fire suppressants typically applied with ground equipment. [5]
The European Union (EU) has not set a daily intake limit for two types of pectin, known as E440(i) and Amidated Pectin E440(ii). The EU has established purity standards for these additives in the EU Commission Regulation (EU)/231/2012. Pectin can be used as needed in most food categories, a concept referred to as "quantum satis". [47]
A controlled burn may also refer to the intentional burning of slash and fuels through burn piles. [1] Controlled burns may also be referred to as hazard reduction burning, [2] backfire, swailing or a burn-off. [3] In industrialized countries, controlled burning regulations and permits are usually overseen by fire control authorities.
Fire control is the practice of reducing the heat output of a fire, reducing the area over which the fire exists, or suppressing or extinguishing the fire by depriving it of fuel, oxygen, or heat (see fire triangle). Fire prevention and control is the prevention, detection, and extinguishment of fires, including such secondary activities as ...
Fire extinguishers are one of the most common manual fire suppression devices and are required in all commercial buildings and vehicles. [2] Fire extinguishers can be used with little to no training and are meant for small incipient stage fires. The most common extinguisher is the ABC extinguisher and are found in most offices and homes.
The control of fire by early humans was a critical technology enabling the evolution of humans. Fire provided a source of warmth and lighting , protection from predators (especially at night), a way to create more advanced hunting tools, and a method for cooking food.
Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902. [1] The surfactants used must produce foam in concentrations of ...
Gaseous fire suppression, also called clean agent fire suppression, is the use of inert gases and chemical agents to extinguish a fire. These agents are governed by the National Fire Protection Association (NFPA) Standard for Clean Agent Fire Extinguishing Systems – NFPA 2001 in the US, with different standards and regulations elsewhere.
