Are balloons flammable and explosive, and what items are flammable and explosive?

Balloons are inherently flammable. The materials used are flammable.

There is also a kind of hydrogen balloon that children play with, which is even more flammable.

How can hydrogen balloons bought for children become dangerous goods? Open flame ignition or electric spark ignition may ignite the mixture of hydrogen and oxygen, and in winter, the air is dry, and the static electricity generated by people's clothes will cause hydrogen balloons when the balloon leaks or bursts**, once multiple hydrogen balloons are chained back, its power is no less than an incendiary bomb, so hydrogen balloons are also listed in the list of flammable and explosive contraband that are currently prohibited from being brought on buses.

Let me tell you about an incident at 6 p.m. on December 19, 2017, when Ding Guopeng, the driver of No. 2 No. 2 of the first branch of Qingdao Public Transport Shibei Bus Company, drove to Taitung Station, a child with a balloon in his hand attracted his attention, because the child was not holding an ordinary balloon, but a "net red" balloon that had recently aroused heated discussions on the Internet, and the driver Ding Guopeng immediately told the child's parents that this balloon is a flammable and explosive dangerous product, in order to ensure the safety of the whole car, please do not take the balloon on the bus, The parents had no choice but to lead the child out of the car.

According to the safety personnel of the first branch of Shibei Bus, like this kind of cheap balloon, which is generally filled with hydrogen, is a flammable and explosive gas, in the bus compartment this relatively closed space, the static electricity generated by the friction of chemical fiber clothes, crowding, may trigger the surface of the balloon, resulting in the combustion of the balloon full of hydrogen, such as the open flame will cause instant, will bring great harm, the consequences are very serious.

It depends on what kind of balloon it is, if it is blown by yourself, it is not flammable, if it is a balloon bought on the street, it must be a flammable balloon, because most of the balloons bought on the street are made of hydrogen as a material, and it is cheap.

Balloons depend on the gas they are filled, hydrogen balloons are flammable and explosive, and air, nitrogen and other gases are not flammable and explosive. However, although balloons filled with air and nitrogen are not flammable and explosive, security checks in subways and trains are generally not allowed because of certain dangers.

The balloon is filled with hydrogen or helium. Since hydrogen and helium are both lighter gases than air, balloons are in the air like wood in water, buoyant upward and gravity downward. When the buoyancy is greater than the gravitational force, the balloon can fly into the sky.

I believe everyone is no stranger to balloons flying into the sky, but do you know why? Some people say that it is because the balloon is filled with special gas, so do you know what gas is filled in the balloon?

Balloons are usually filled with hydrogen or helium. Hydrogen or helium is much lighter than the same volume of air, so a balloon filled with hydrogen or helium will have more lift. If you hang a big basket under the balloon, you can take people to the sky.

In addition, there is now a hot air balloon that is filled with hot gas. We know that hot air is lighter than cold air, and when the balloon is filled with hot air, it will be buoyant upward by the cold air around it, causing the balloon to rise, and if the heat is controlled, it can stay at different altitudes.

The balloon will slowly disappear after flying into the sky, so what about the balloon after it flies into the sky? Did you go to space? In fact, it happens when the balloon flies to a certain height**.

When the balloon rises in the air, the outside air pressure is also changing with the increase in altitude, when the balloon flies higher, the thinner the air will be, the air density will become smaller, and the gas density inside the balloon is relatively larger and larger, so the balloon will slowly expand, when the balloon material can not continue to expand, the balloon will occur, unable to continue to rise.

If it is a hydrogen balloon, it is flammable and explosive. Helium balloons are safer.

Balloons are inherently flammable. The materials used are flammable.

Depending on what kind of gas is filled inside, hydrogen must be flammable and explosive.

Flammable and explosive, of course.

The kind that can float up basically belongs, and it doesn't count if you blow it yourself.

Look at what kind of gas is filled inside.

1. Except for natural gas, liquefied gas steel cans, gasoline drums, paint, alcohol, banana water, lighters and other items.

2. Toilet water, perfume, nail polish, gel cream, antiperspirant, mosquito repellent, insecticide, air freshener, canned carbonated drinks, etc. are not easy to notice. Among them, toilet water is more dangerous, its alcohol content is 70%-75%, and the ignition point is only 24.

Flammable and explosive products are basically compounds containing carbon and hydrogen, which are chemically called hydrocarbons. Hydrocarbons have the characteristics of low melting and boiling points, high volatility and easy combustion. In the summer, when the ambient temperature is quite high, if you are careless, it is very easy to cause fire.

The vast majority of organic compounds with carbon and hydrogen as the parent are combustible and flammable, which is one of the characteristics of organic compounds. Most organic poisons are not only toxic, but also flammable, and some have very low flash points (such as allyl cyanide, allyl sulfur, ethylpyridine, etc.), but they are listed as poisons because of their prominent toxicity;

There are also highly toxic organic compounds (such as acrylonitrile) that are classified as flammable liquids because of their greater risk of combustion; There are many organic corrosives that are corrosive and flammable at the same time, and they are also included in the corrosive products because of their significant corrosiveness. Looking at the inorganic compounds in these two categories, although some of them are not combustible, they can promote the combustion of flammable and flammable materials because they have oxidation effects (such as nitric acid, perchloric acid, hydrogen peroxide, bleaching powder, etc.);

or flammable and highly toxic gases (such as cyanide, etc.) are released due to acid;

or gases that are highly toxic and can spontaneously ignite due to water and acids (such as phosphorus metal compounds, etc.), are directly or indirectly related to fire prevention. In addition, some chemicals such as highly toxic hydrogen cyanide, liquid chlorine, flammable hydrogen, liquid hydrocarbon gas, combustible compressed air, oxygen, non-flammable and low-toxic refrigerants Freon, and even non-flammable and non-toxic carbon dioxide, nitrogen, etc., must be stored in pressure-resistant cylinders.

According to the relevant provisions of the Fire Protection Law of the People's Republic of China, flammable and explosive dangerous goods" include civil ** articles and compressed gases and liquefied gases with combustion as the main characteristic in the national standard "List of Dangerous Goods" (GB12268 90); explosive liquids; flammable solids, spontaneously combustible materials and flammable materials when wet; oxidizing agents and organic peroxidants; Some flammable and explosive chemicals in poisons and corrosives.

At present, there are more than 1,000 common and widely used ones.

In 1994, the Ministry of Public Security promulgated the Measures for the Supervision and Administration of Fire Safety of Flammable and Explosive Chemicals (Order No. 18 of the Ministry of Public Security <1994>), which made specific provisions on the fire supervision and management of the production, use, storage, operation and transportation of flammable and explosive chemicals.

Flammable, explosive, and dangerous goods include these ten categories? (1) ** product. Such as detonators, explosives, fuses, firecrackers, fireworks, lighters, etc.

2) Flammable liquids. Such as gasoline, kerosene, alcohol, banana water, turpentine, paint, etc. (3) Flammable solids.

Is peanut oil extraction a flammable substance?

The common flammable gases in our daily life are: natural gas, liquefied petroleum gas, biogas, gas, and coal gas.

1. Natural gas.

Natural gas is a gaseous hydrocarbon produced by the long-term deposition of paleontological remains underground, through slow transformation and metamorphic cracking, which is flammable and mostly accompanied by oil field exploitation.

The main component of natural gas is methane, and it also contains small amounts of ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc. Specific gravity, lighter than air, colorless, odorless, non-toxic characteristics, natural gas companies are in accordance with the provisions of the addition of odorants, so that users sniff.

Lighter than air, generally our installation method is 30-60cm above the ceiling, heavier than air, installed at 30-60cm below.

Natural gas general application field owned:

Civil fuel: Natural gas is the preferred fuel for civil gas, with low cost, high calorific value, safety performance and good environmental performance.

Industrial fuels: Natural gas instead of coal for factory heating, production boilers and gas turbine boilers in thermal power plants.

3) Process production: such as baking paint production line, tobacco leaf drying, asphalt heating and insulation, etc.

2. Liquefied petroleum gas.

Liquefied petroleum gas (LPG) is obtained from the process of petroleum processing or oil and natural gas extraction, and its main components are propane, propylene, butane and butylene. Gaseous LPG is heavier than air, and its specific gravity is twice that of air.

When the concentration of liquefied petroleum gas in the air is high, it has an anesthetic effect on the central nervous system of the person, and if the combustion is not complete, it will produce toxic gases such as carbon monoxide. Liquefied petroleum gas (LPG) has a special odor that can be detected once it leaks. Liquefied petroleum gas is flammable and explosive after mixing with air, and when the concentration of liquefied petroleum gas in the air is reached, it will encounter fire, so it is necessary to prevent leakage.

When LPG is completely combusted, it requires a large amount of air to support combustion.

3. Biogas. Biogas is a combustible gas produced by organic matter under the condition of isolating air and a certain temperature, humidity, pH, etc., through the action of biogas bacteria. Since this gas was first discovered in swamps, it is called biogas.

The main component of biogas is methane, the rest is carbon dioxide, oxygen, nitrogen and hydrogen sulfide. The methane content is about 55% to 70%, and the carbon dioxide content is about 30% to 45%. Biogas is a gas mixture.

4. Gas. Methane, the main component of gas, is a flammable gas, colorless and odorless, insoluble in water, less dense than air, and easy to occur in a certain space after reaching a certain temperature after mixing with oxygen or air.

5. Gas. The main components of coal gas are carbon monoxide, hydrogen, and alkanes, olefins, aromatics, etc. Coal gas is toxic because the carbon monoxide and aromatic hydrocarbons in it can combine with hemoglobin in the human body, causing hypoxia, making people unconscious or even dying, and at low concentrations, it can also make people dizzy, nauseous and prostrate.

Therefore, special care should be taken when using gas, gas pipelines, stoves and related valves should be checked frequently, and the valves should be closed tightly after each use to prevent leakage.

Common flammable and explosive gases include hydrocarbons, carbon monoxide, methane, propane, ethylene, ethane, acetylene and other hydrocarbons, as well as hydrogen sulfide.

Hope it helps.

Flammable and flammable items are:Hydrogen, carbon monoxide, methane, ethane, natural gas, liquefied petroleum gas, freon, oxygen, gasoline drums, kerosene, alcohol paint, banana water, lighters, toilet water, perfumes, pesticides, nail polish, gel cream, antiperspirants, mosquito repellent air fresheners, canned carbonated drinks, and more.

All kinds of articles that are flammable, explosive, highly toxic, radioactive, corrosive and contradictory in nature must be classified and properly stored, strictly managed, well ventilated, and clearly marked. Use explosion-proof lamps in warehouses and flammable, explosive dust and gas places.

Harmfulness. 1.Prone to burning.

The main danger characteristic of flammable gas is that it is flammable and explosive, and flammable gases within the range of combustion concentration can catch fire or explosion when they encounter an ignition source, and some can even be ignited with only a very small amount of energy. Compared with flammable liquids and solids, flammable gases are easier to burn, and they burn quickly, and they are burned out as soon as they are burned. Gases composed of simple components are more flammable than gases composed of complex components, have a fast combustion rate, have a high flame temperature, and have a greater risk of ignition.

2.Fast diffusion.

Compressed and liquefied gases are very easy to diffuse due to their large molecular spacing and low interaction forces, and can spontaneously fill any container. The diffusion of gases is affected by specific gravity: gases that are lighter than air can diffuse indefinitely in the air and are easy to form mixtures with air; After the gas heavier than air diffuses, it often gathers on the surface, ditches, tunnels, dead corners of the plant, etc., and does not disperse for a long time, and burns when it encounters an ignition source.

3.Shrinkage and expansion.

The thermal expansion and contraction of compressed gases and liquefied gases are much larger than those of liquids and solids, and their volume expands and contracts with the rise and fall of temperature.

4.Electrostatic.

When compressed and liquefied gases are ejected at high velocity from the nozzle or from a broken area, static electricity is generated due to strong friction. Electrification is also one of the parameters for assessing the fire hazard of compressed and liquefied gases.

5.It is highly corrosive and toxic.

Mainly some gases containing hydrogen and sulfur have corrosive effects. Such as hydrogen, ammonia, hydrogen sulfide, etc. can corrode the equipment, and in severe cases, it can lead to cracks and gas leakage in the equipment.
