To quickly assess the potential weapons or tools in the environment for self-defense in an emergency, you can follow these steps: 1. **Quick environmental scan**: - Quickly observe the surrounding environment and look for objects that can be used as weapons or defensive tools, such as furniture, tools, bottles, etc. 2. **Assess item availability**: - Identify objects that can be quickly obtained and used. For example, heavy objects (such as chairs, vases), sharp objects (such as knives, scissors), or objects that can be thrown (such as rocks, bottles). 3. **Identify defensive tools**: - Look for objects that can block attacks, such as large furniture, walls, doors, etc. to form a cover. - Look for doors or exits that can be locked to ensure that the escape route is unobstructed. 4. **Think about emergency plans**: - Quickly develop an escape route and confirm the location of the safe exit or safe area. - If there are other people with you, make sure they also understand the escape plan. 5. **Use the environment to your advantage**: - Use the environment for concealment or camouflage, hide in an inconspicuous place, and observe the enemy. - If you are in a higher position, consider taking advantage of gravity and looking for objects that can be dropped from a height. 6. **Stay Calm and Focus**: - Stay calm and avoid panic, so that you can more effectively assess the situation and make decisions. 7. **Seek Help**: - If it is safe, you can seek help from others. Collective action is usually more effective. In any case, try to focus on escaping rather than confrontation, and avoid direct conflict if it is not necessary. It is crucial to follow safety principles when assessing and responding to crises.
