Fires and explosions require three elements in order to occur (the 'fire triangle'): oxygen, fuel and heat.
These elements are fuel, heat and oxygen. These three elements make up the fire triangle.
These three elements are known as the “fire triangle”; if one of these elements is missing, a fire will not occur. The elements are a fuel source (combustible dust), heat or ignition source (electrostatic discharge, glowing ember, hot surface) and an oxidizing agent (oxygen in the air).
Possessing, detonating, or otherwise maximum hazard; such as dynamite, nitroglycerin, picric acid, lead azide, fulminate of mercury, black powder, blasting caps, and detonating primers.
PROPERTIES OF EXPLOSIVES
These properties are: detonation velocity, density, detonation pressure, water resistance, and fume class. For a given explosive, these properties vary with the manufacturer.
Class 3 dangerous goods are flammable liquids with flash points no more than 60 celcius degrees. It covers liquid substances, molten solid substances with a flash point above 60 celcius degrees and liquid desensitized explosives.
These five factors (oxygen, heat, fuel, dispersion, and confinement) are known as the “Dust Explosion Pentagon”. If one element of the pentagon is missing, an explosion cannot occur.
Explosions are caused by a range of complex reactions which result in the rapid expansion of gas and energy, forming an explosion. When certain gases are exposed to heat or increased pressure, reactions will take place to stimulate the explosion.
The hydrogen mixes with oxygen in the air forming an explosive mixture. Because the hydrogen and oxygen must mix before an explosion can occur, the explosion is relatively slow and diffuse.
The recipe for black powder, or gunpowder, the basic material in all fireworks, has remained the same since it was discovered in China about 1,000 years ago: 75 percent saltpeter (potassium nitrate), 15 percent charcoal, and 10 percent sulfur.
There are three main types of explosions: chemical, mechanical and nuclear. Each type of explosion can be equally devastating and serious, causing unprecedented harm to the surrounding people, atmosphere and infrastructure.
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its "bang" from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
The heavier alkali metals (rubidium and cesium) will spontaneously ignite upon exposure to air at room temperature.
Antimony - THE MOST EXPLOSIVE ELEMENT ON EARTH!
Therefore, the reactivity of metals increases. Now among the given options, the reaction between Chlorine and potassium will be most violent. This is because according to the periodic properties the reactivity of potassium and chlorine is very high.
A dust explosion occurs within a confined space when tiny particles in the air spontaneously ignite. Dust explosions can occur when any distributed combustible dust is present in high enough quantities in the atmosphere or another oxidizing gaseous media, such as pure oxygen.
The four basic mechanisms of blast injury are termed as primary, secondary, tertiary, and quaternary (Table 1). “Blast Wave” (primary) refers to the intense over-pressurization impulse created by a detonated HE.
Dangerous goods diamond signs are hazard signs used for areas where dangerous goods are transported or may be stored. This flammable liquids sign features a flame symbol above the words flammable liquid followed by a large, bold number 3. The sign comprises a red background with black wording and symbols.
Risk level 3: Materials extremely hazardous to health, but areas may be entered with extreme care. Full protective clothing including self-contained breathing apparatus, coat, pants, gloves, and boots, with bands around the legs, arms, and waist should be provided. No skin surface should be exposed.
It is made by combining toluene with a mixture of nitric acid and sulfuric acid. 2,4,6-Trinitrotoluene is also known by other names such as sym-trinitrotoluene, TNT, and 1-methyl-2,4,6-trinitrobenzene. 2,4,6- Trinitrotoluene is produced in the United States only at military arsenals.
Answer and Explanation: The chemical elements that explode when water touches them are lithium, sodium, potassium, rubidium, and cesium.
Liquids (such as petrol and other fuels) and solvents in industrial products (such as paint, ink, adhesives and cleaning fluids) give off flammable vapour which, when mixed with air, can ignite or explode.
PETN. One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
Summary: RDX stands for Royal Demolition eXplosive. It is also known as cyclonite or hexogen. The chemical name for RDX is 1,3,5-trinitro-1,3,5-triazine.
