How to buy guns scientifically and safely? (Buy fireworks and set off fireworks).
First, there is a problem.
Personal safety. Every Chinese New Year, brush Douyin, headlines, every time I see "Children Throw Firecrackers to the Sewer**, the manhole cover is blown up!" Local Response", every time the heart hurts, especially when a child or passerby is injured. You must know that the power of fireworks and firecrackers is not large, but in some special circumstances, it will cause devastating harm, especially for the safety of human life. People only have one life, even if they have been injured, it is always different from not being injured, for example, people who have undergone surgery cannot participate in some special sports activities, otherwise there is danger.

The car body smoked, and bricks were scattered all over the ground (screenshot from the Internet).
The staff of the Chenjiaba Sub-district Office confirmed to reporters that in the afternoon of the same day, a child threw firecrackers into the sewer and caused **, multiple manhole covers were blown up, and a child was slightly injured. The staff of the Wanzhou District Emergency Bureau said that a child set off firecrackers in the sewer caused **, and a child was injured in the face, "(the place of the incident) may have been hit by the biochemical pool."
2.Fire safety.
If the purchase and discharge of fireworks and firecrackers are not reasonable and appropriate, it will cause large fire safety hazards, especially the surrounding flammable and explosive items, such as natural gas pipelines, wires, etc. In particular, many old people who have just entered the city are reluctant to spend money and pile up the waste products they have picked up all over their homes.
Seeing "Heartbreak! Fireworks in the community caused a fire, and the old man died in the smoke! On the evening of January 30, 2024, a netizen in Guiyang City, Guizhou Province posted: "Because someone in the community set off fireworks and caused a fire, after calling 119, we rescued ourselves as soon as possible. ”
On the evening of the 31st, the Yunyan District People's ** Information Office issued a briefing. According to the report, after a preliminary investigation, the cause was caused by fireworks and firecrackers, and sparks splashed into the room to ignite debris. During the rescue process, it was found that the fire hydrant could not be used normally due to the lack of hose interface. One trapped person was rescued at the scene and immediately sent to the hospital for treatment, but he died after all-out rescue.
3.Environmental pollution (air pollution, noise pollution).
The discharge of fireworks and firecrackers will cause air pollution and noise pollution, every new day lasts for a week, we used to always be able to smell the smell of fireworks one by one, into the nasal cavity, particularly uncomfortable, some urban communities set off firecrackers, the neighbor's window glass is really broken, but it is really "broken and peaceful", it can be seen that the noise of fireworks is big, the power is great!
By analyzing the trend of air quality, we found PM25. PM10 and SO2 concentrations will increase rapidly during the fireworks display period (Chinese New Year's Eve night to the morning of the first day of the new year), and the trend is basically the same.
PM2 in Beijing, Shijiazhuang and Baoding during the Spring Festival from 2017 to 20205 and fireworks contribute to the hourly variation.
Data**: China National Environmental Monitoring Station, Mapping: Chinese Academy of Environmental Sciences).
From PM2The 5 components can also reflect the impact of fireworks on air quality. Fireworks produce a large amount of chloride ions, potassium ions, magnesium ions, etc., which can be used as tracer components of fireworks. pm2.The real-time monitoring results of 5 components showed that PM2 in typical cities in the Beijing-Tianjin-Hebei region (Beijing, Shijiazhuang and Baoding) from the night of Chinese New Year's Eve to the early morning of the first day of the new year5. The concentrations and proportions of chloride ions, potassium ions, and magnesium ions increased significantly, which further indicated that PM2 was caused by the concentrated discharge of fireworks5. The concentration increased rapidly, and the air quality deteriorated rapidly.
2. Phenomenon analysis
Improper way of purchasing substandard products and setting off fireworks.
The overall quality of inferior fireworks is not ***Inferior fireworks use a large number of homemade gunpowder, and the quality of fireworks and firecrackers produced is not high, and it is easy to have problems such as insufficient number of heads, low sound rate, instability, fire failure, and gunpowder leakage.
Inferior fireworks contain unstable ingredients. In order to reduce costs, chlorates are often used in low-quality fireworks, which are prohibited by compliant fireworks. Because the chemical properties of chlorate substances are unstable, they are easy to cause under the same high temperature, friction and other conditions.
The packaging and cover of inferior fireworks and fireworks products are unqualified. The packaging of inferior fireworks and firecrackers is simple, which is prone to damage, resulting in gunpowder leakage and potential safety hazards. At the same time, some inferior fireworks and firecrackers do not have warnings, production dates, certificates and other signs on the outer packaging, resulting in consumers encountering expired products, or causing accidents due to the inability to operate correctly and causing accidents caused by the wrong way of fireworks.
2.Illegal production, operation, transportation, and storage of fireworks.
The harm of illegal production: Illegal production is extremely harmful, and it is very easy to cause ** and combustion accidents, resulting in catastrophic consequences of mass deaths and injuries. Engaging in illegal production of fireworks and firecrackers is not only highly dangerous, but also a potential and indirect threat to the safety of the lives and property of the surrounding people.
The harm of illegal business activities: Driven by high profits, illegal traders do not have relevant professional knowledge and do not know how to avoid risks, illegally purchase and sell fireworks, there are great potential safety hazards, and a little carelessness will cause irreparable losses. At the same time, the illegal purchase and sale of fireworks lacks strict management, and the quality cannot be guaranteed.
The harm of illegal transportation: illegal transportation of fireworks and firecrackers vehicles do not have the corresponding qualifications, do not have the conditions for transporting fireworks and firecrackers, if there is extrusion and collision during transportation, it is easy to cause ** and combustion accidents, causing great harm to road transport safety.
The harm of illegal storage: the storage of fireworks and firecrackers dens are generally located in rental houses, abandoned factories, idle courtyards, without the assessment and acceptance of relevant departments, do not have the conditions for storing fireworks and firecrackers, and the surrounding environment, personnel, etc. are more complex, if a large number of fireworks and firecrackers are stacked in this small space, it is like a "time bomb" that will be the first at any time, with great potential safety hazards, and will pose a great threat to the safety of the lives and property of the surrounding residents.
3.The quality of fireworks is low, and people's purchasing power is low
Many people in our country, especially farmers, account for a large proportion of them, they want to buy fireworks to celebrate the festival, but they are unwilling to buy high-quality fireworks, which partly leads to the generation of fire hazards.
First, the overall quality of inferior fireworks is not ***, inferior fireworks use a large number of homemade gunpowder, and the quality of fireworks and firecrackers produced is not high, and it is easy to have problems such as insufficient number of heads, low sound rate, instability, fire failure, and gunpowder leakage.
2. Inferior fireworks contain unstable ingredients. In order to reduce costs, chlorates are often used in low-quality fireworks, which are prohibited by compliant fireworks. Because the chemical properties of chlorate substances are unstable, they are easy to cause under the same high temperature, friction and other conditions.
3. Prescribe the right medicine
Purchase qualified products and set off fireworks correctly
It is necessary to buy it at a regular fireworks and fireworks shop that has a fireworks business license and a business license.
When purchasing, pay attention to check whether the appearance of the product is complete, no obvious deformation, no damage, no leakage, no mildew; Also pay attention to check the product identification, whether there is a factory name, factory address, qualification mark, warnings, fireworks precautions, Chinese fireworks instructions, etc.: do not buy "three no" "white pole" fireworks.
When purchasing fireworks and firecrackers, you can reasonably purchase fireworks and firecrackers according to your age, setting site, etc., and you should choose C and D grade products with less dosage and relatively good safety.
All fireworks should be set off in a spacious, safe outdoor venue, upwind and viewed.
Do not go near firewood stacks when setting off fireworks, and do not throw lit fireworks into crowds, oil pipes, sewers, etc.
Children should be supervised by an adult, and children should not be allowed to set off dangerous species.
2.Production, operation, transportation and storage of fireworks in compliance
Manufacturers can't afford to cut corners on the production line for greater profit.
Employees must go through fire training and be proficient in the common sense of fighting and escaping from the first disaster.
Enterprises need to have a safety production management organization and full-time safety production management personnel, and have an accident emergency rescue plan and necessary emergency rescue equipment and equipment.
Enterprises should not stack fireworks in a large number of closed warehouses, let alone in direct sunlight or high temperature environments, and the storage of fireworks and firecrackers should be managed in partitions.
The number of fireworks and firecrackers stored in homes and residential places should be reduced as much as possible, and the storage time should be shortened, and they must be kept away from fire sources, heat sources, power sources and flammable and explosive places.
Fireworks should be protected from rain and moisture, and should be packed in cartons or other containers as much as possible to prevent cats, dogs, insects, and rats from biting spontaneous combustion
Reasonable purchases**High-quality fireworks, set off in open areas
Try to buy as few fireworks as possible, buy less, buy high-quality fireworks products, high safety factor, low pollution. Choose low-smoke, low-noise fireworks products, and try to avoid buying fireworks that contain harmful substances such as heavy metals. When setting off fireworks, try to choose an open outdoor area and maintain ventilation to reduce air pollution in a small area. Carry out fireworks at the specified time and area of **, and avoid setting off fireworks in densely populated areas and periods with poor air quality.
