There are many dangers in exploring abandoned buildings. Here are some of the thrilling factors that need special attention: 1. **Structural safety hazards** - **Building structure damage**: Abandoned buildings have been in disrepair for many years, and the walls may be cracked and tilted, and the floor slabs may be damaged, and there is a risk of collapse at any time. For example, in large factories in old factories, the steel beams on the roof may be fragile due to rust, and the slightest touch may cause the entire roof to collapse. - **Stairs and handrails**: Stairs may be loose and rotten, and handrails may be shaky. When climbing, these parts are very likely to be damaged by the weight of the body, causing people to fall and get injured. 2. **Dangerous items left** - **Chemicals**: Various chemicals may remain in abandoned buildings, such as acid and alkali solutions from industrial waste. Once they come into contact with the skin or eyes, they will cause serious corrosive damage. For example, some abandoned printing and dyeing factories may have highly corrosive dye intermediates left. - **Sharp objects**: There may be sharp objects such as glass fragments and rusty metal scraps scattered on the site, and it is easy to get scratched when walking in the dark. - **Inflammable and explosive materials**: Some abandoned buildings, such as abandoned gas stations or chemical plant warehouses, may have flammable and explosive dangerous goods left. Even a small spark may cause a violent explosion, with disastrous consequences. 3. **Threat to wild animals** - **Venomous snakes and poisonous insects**: Abandoned buildings provide habitats for wild animals, and may hide poisonous creatures such as poisonous snakes, poisonous spiders, and scorpions. If they are accidentally disturbed, they are easily attacked, and bites may cause serious poisoning reactions. - **Stray animals**: There may also be stray dogs, stray cats and other aggressive animals here. They may hurt people because of being frightened in an unfamiliar environment. 4. **Air quality issues** - **Toxic gases**: Various toxic gases may accumulate in the building, such as carbon dioxide, hydrogen sulfide, carbon monoxide, etc. In a long-term closed space, the concentration of these gases may be very high, and entering will cause poisoning or even life-threatening. For example, some abandoned underground mines may have high concentrations of hydrogen sulfide gas. - **Dust**: A large amount of dust may permeate the air and can be easily inhaled into the lungs, causing respiratory diseases. 5. **Lack of safe passages and lighting** - **Complex and difficult to distinguish passages**: The internal layout of abandoned buildings is chaotic, and the passages are intricate and it is easy to get lost. Some abandoned hospitals or large factories have many rooms and winding corridors. After entering, you may quickly lose your way. - **Insufficient lighting**: There are usually no normal lighting facilities, and you can only rely on temporary lighting tools such as flashlights. The dim light will affect your vision and increase the chances of accidents such as falls and collisions. In the blind spots of light, there may also be unknown dangers hidden. 6. **Legal risks** - **Illegal trespass**: Sneaking into abandoned buildings is an illegal trespass and may face legal sanctions. Once discovered, you will be fined, detained, and other penalties, which will bring you unnecessary trouble.
