# Defense Evaluation Guide in Emergencies In a sudden danger situation, it is critical to quickly assess potential defense tools in the surrounding environment. The following is a systematic evaluation method： ## Environmental assessment principles 1. **Distance priority**: The nearest accessible item is preferred 2. **Hard and heavy**items are usually the best choice 3. **Long objects** Can provide distance advantage 4. **Ready-to-use**Items are better than items that need to be prepared ## Potential defense tools in common environments ### Office environment -Chair (can be raised to block or pushed towards the attacker) -Laptop/monitor (can be used as a shield) -Folder/thick book (defensive tool) -Fire extinguisher (jet or as a weapon) ### Public place -Backpack/handbag (waved or blocked) -Umbrella (stab and defense) -Hot drink (sprinkled) -Public facilities such as trash cans, signs, etc. ### Home environment -Kitchen utensils (pots, pans, knives) -Tools (hammer, wrench) -Cleaning supplies (broom, mop) -Decorations (vases, candlesticks) ## Emergency defense skills -Prioritize escape rather than confrontation - Throw multiple small items at the attacker to create interference -Use the environment (such as tables and chairs) to create barriers -Find a safe area where the door can be locked Remember, the best self-defense strategy is to avoid conflict as much as possible and use this knowledge only when absolutely necessary.
