Although diving into abandoned buildings (also known as “urban exploration”) is attractive, it is also accompanied by multiple risks. The following are the risk factors and coping suggestions that need to be vigilant： --- ###**1. Hidden dangers of structural safety** 1. **Risk of collapse** -The floors, stairs, and ceilings of old buildings may collapse suddenly due to corrosion or moth-eaten insects, especially in areas with severe wooden structures or metal corrosion. -**Response**: Tap with a wooden stick to test the load-bearing of the floor, avoid cracks or sloping walls, and avoid multiple people standing in concentration. 2. **Falling from high altitude** -Damaged stairs, missing railings, and hidden shafts (such as elevator shafts) may cause falls. -**Response**: Bring a strong flashlight to explore under your feet, avoid relying on mobile phone lighting, and use ropes to assist if necessary. --- ###**2. Chemical and biological hazards** 1. **Toxic substances** -Asbestos (commonly found in pipes/ceilings of old buildings), mold, and chemical residues (such as chemicals from abandoned factories) may cause respiratory diseases or skin infections. -**Response**: Wear an N95 mask and gloves, avoid touching unknown liquids or dust, and clean your clothes thoroughly after the end. 2. **Threats to wildlife** -Bats, mice, and stray dogs may carry germs (such as rabies), and insects (such as poisonous spiders) or snakes may attack humans. -**Response**: Wear long-sleeved trousers and high-top shoes, avoid flipping debris, and seek medical attention immediately after being bitten. --- ###**3. Man-made hazards** 1. **Traces of illegal activities** -Abandoned buildings may be used for drug dealing, hiding stolen goods, or crime scenes. Conflicts may arise if suspicious persons are encountered. -**Response**: Evacuate immediately if you find traces of needles, blood, etc., avoid late-night actions, and keep a low profile. 2. **Traps and organs** -Some buildings may be deliberately set with traps (such as animal traps) or there may be security devices that have not been removed (such as barbed wire, broken glass). -**Response**: Observe abnormal traces on the ground and walls, and carry multi-function tools to deal with obstacles. --- ###**4. Environmental and physiological risks** 1. **Darkness and enclosed space** -Basements, tunnels and other areas may be hypoxic or accumulate toxic gases (such as carbon monoxide), and sudden panic or claustrophobia may lead to errors in judgment. -**Response**: Bring a portable oxygen detector, act together, and plan an escape route in advance. 2. **Risk of getting lost** -Complex structures or similar rooms can easily make people disoriented, especially in environments with power outages or no natural light. -*****: Mark the path with fluorescent stickers or chalk, and download offline maps from your phone (such as satellite views from Google Maps). --- ###**5. Legal and ethical issues** - **Trespassing**: Even if the building is abandoned, the property rights may still belong to the private or government, and trespassing may face fines or detention. -**Response**: Check the ownership of the land in advance, and if you encounter security guards or police, maintain a cooperative attitude. --- ###**List of necessary equipment** -**Protective category**: helmet, non-slip gloves, knee pads, dust mask. -**Tools**: Strong light flashlight (spare battery), first aid kit, whistle, portable power bank. -**Emergency category**: Drinking water, high-calorie food, emergency contact card (indicating blood type and allergy history). --- ###**Final suggestion** -**Team action**: At least 2-3 people travel together to make sure someone knows your whereabouts and estimated return time. -**Retreat at any time**: If you feel unwell or find signs of danger (such as abnormal noise and odor on the wall), leave immediately. -**Respect the place**: Do not destroy the building structure and do not take leftover items (there may be historical or legal disputes). The charm of urban exploration lies in the unknown, but safety is always the first prerequisite. If you are not fully prepared, it is recommended to use documentary or photographic works “Cloud adventure” to avoid taking risks.
