由 lltx1822 “The Hazards of Common Prohibited Items and Why Their Transportation is Forbidden”
In the field of transportation, there are many prohibited items whose transportation is strictly prohibited. This is not an arbitrary regulation, but because each of these items poses serious risks.
Explosive items, such as bombs, grenades, explosives, detonators, fireworks, and firecrackers, are extremely destructive. When they explode, the powerful shockwaves and high temperatures generated can instantly destroy surrounding buildings and facilities, causing a large number of casualties and property losses. During transportation, the 颠簸 and vibration of vehicles, as well as possible friction and collisions, may trigger the accidental explosion of explosive items. For instance, a truck transporting fireworks and firecrackers experienced significant 颠簸 due to poor road conditions during its journey. As a result, the fireworks and firecrackers inside collided with each other and ignited, ultimately leading to a violent explosion. The truck was completely destroyed, and several surrounding vehicles and buildings were also affected, causing serious casualties and traffic congestion.
Flammable items are also common prohibited items. Flammable liquids like gasoline, alcohol, kerosene, paint, and rosin oil, as well as flammable solids such as red phosphorus, flash powder, and solid alcohol, have a relatively low ignition point. During transportation, once they encounter an open flame, high temperature, or static electricity, they are highly likely to catch fire. Moreover, when flammable liquids volatilize, the resulting combustible vapor, when mixed with air at a certain concentration, can also cause an explosion. For example, a gasoline tanker once had an accident during the loading and unloading process. Due to improper operation, static electricity was generated, igniting the gasoline and causing an explosion. The fire spread rapidly, bringing great disasters to the surrounding environment.
Poisonous substances, such as cyanide, arsenic, and pesticides, pose a fatal threat to both human beings and the environment. These substances are highly toxic. Once they leak, they can spread through the air, water, and other media, poisoning people who come into contact with them and, in severe cases, leading to death. At the same time, poisonous substances can cause long – term pollution and damage to the soil, water sources, and other ecological environments. For example, a chemical enterprise leaked cyanide during transportation, polluting the surrounding river. A large number of fish died, and the local residents suffered varying degrees of health threats due to water pollution.
Corrosive substances, such as sulfuric acid, hydrochloric acid, nitric acid, and sodium hydroxide, can cause severe damage to various materials. They can quickly corrode metals, rubbers, plastics, and other substances. If there is a slight damage to the packaging during transportation and the corrosive liquid or gas leaks, it will not only corrode the transportation vehicles but may also burn the skin of transportation workers, causing irreversible injuries. Additionally, if leaked into the soil and water bodies, they will change the soil’s pH value, resulting in plant death, polluting water sources, and disrupting the ecological balance.
