It takes calm and quick judgment to quickly assess the environment for potential weapons or tools to defend against an attack in an emergency. Here are some steps and suggestions: 1. **Keep calm**: First, take a deep breath and try to stay calm. Panic will hinder your judgment. 2. **Quickly observe the environment**: Quickly observe the surroundings and identify possible sources of threats and available defensive tools. 3. **Identify potential tools**: - **Everyday objects**: Look for objects that are sturdy and easy to grasp, such as chairs, pens, books, wallets, keys, backpacks, etc. - **Kitchen items**: In the kitchen or dining area, you can use knives, pots, spoons, etc. - **Outdoor objects**: Outdoors, you can use sticks, stones, sand (can be used to interfere with vision), etc. 4. **Use the environment**: - **Space and furniture**: Use tables and chairs as barriers or to block attackers. - **Light and sound**: Use light (such as a flashlight) to stimulate the attacker's eyes, or make noises (such as knocking on objects) to cause confusion and attract others' attention. 5. **Get ready**: Choose items that are easy to carry and use so that you won't be in trouble if you might need to escape. 6. **Avoid direct confrontation**: If possible, prioritize escaping and finding a safe place, and don't rely too much on the items on hand to fight. 7. **Signal for help**: Use any warning equipment or shout for help to attract attention and seek help from others. Remember that safety is the top priority. In the event of an attack, the first choice should be to protect yourself and get out of the dangerous environment as much as possible.
