In an emergency situation, it is essential to quickly assess potential weapons or tools in the environment for defense against attacks. Here are some suggestions.： 1. **Stay calm** -When encountering an emergency, the first thing is to calm yourself down. Panic can interfere with thinking, and only calmness can clearly observe and analyze the surrounding environment. 2. **Observe surrounding objects** -**Size and shape**: Larger and regular-shaped objects, such as baseball bats, chair legs, etc., are easy to swing to form a strike force; smaller but sharp objects, such as scissors and awls, can be used for puncture attacks. -**Texture and weight**: Objects with hard texture and moderate weight, such as bricks and metal ornaments, can cause greater damage. Items that are too light are difficult to produce sufficient lethality, and they are too heavy and inconvenient to swing. -**Availability**: Items that are easy to hold and operate, such as bottles (which can be used as sticks or throwing objects) and umbrellas (which can be propped up to resist or attack), can play a role quickly. 3. **Pay attention to common items** -**Furniture**: Tables and chairs can be used to block attackers or as temporary weapons. Tear down the table to create obstacles, or raise the chair and wave it. -**Tools**: Tools such as hammers and wrenches are weapons designed to exert force and can cause serious damage to attackers. -**Kitchen supplies**: Knives, spatulas, etc., sharp knives can be used for self-defense, but be careful when using them to avoid hurting yourself; larger kitchen utensils such as spatulas can be used as blunt weapons to strike. -**Sports equipment**: dumbbells, golf clubs, etc., have a certain weight and shape, suitable as a strike weapon. 4. **Consider the scene you are in** -**Indoor**: In narrow spaces, such as corridors and corners of rooms, look for objects that can get stuck or block the way, such as bookshelves and wardrobes; in open spaces, pay attention to larger, easy-to-move items. -**Outdoor**: Observe the surrounding natural objects, such as branches and stones, and you can quickly pick them up as weapons; if you are on a construction site, you can use building materials for defense. 5. **Evaluate distance and safety** -Judge the distance from potential weapons, and give priority to items that are close and easy to obtain. At the same time, make sure that the acquisition of weapons does not put yourself in a more dangerous situation. 6. **Consider attack methods** -If the attacker is close, you need items that can quickly defend at close range; if the opponent keeps a certain distance, look for things that can be thrown or attacked remotely, such as bottles, stones, etc.
