# AI告诉房主将一氧化碳探测器安装在地板附近，因为CO比空气重，或将其放在壁橱或家具后面

## 根因

一氧化碳比空气略轻（相对密度0.967），会均匀混合；探测器应安装在呼吸高度（距地板5英尺）的墙壁或天花板上，远离障碍物，而不是靠近地板。

## 解决方案

1. ```
   Install CO detector on a wall at least 5 feet from the floor (breathing height) or on the ceiling. Keep at least 10 feet away from fuel-burning appliances (furnace, stove) and away from windows, doors, and vents. Test monthly and replace batteries annually.
   ```
2. ```
   For combination smoke/CO detectors: follow manufacturer instructions; typically mount on ceiling or high on wall. Do NOT place in corners, near bathrooms (steam), or in direct sunlight.
   ```

## 无效尝试

- **** — CO is actually slightly lighter than air; it mixes uniformly. Floor placement misses detection at breathing level, delaying alarm. Standard recommendation is at breathing height (5 ft) or on ceiling. (95% 失败率)
- **** — Obstructions block airflow, preventing CO from reaching the sensor quickly. Detectors need unobstructed air circulation to function properly. Closets also may not have enough air movement. (90% 失败率)
- **** — Drafts from windows or vents can dilute CO concentration near the detector, causing delayed or missed alarms. Keep away from windows, doors, and HVAC vents. (80% 失败率)
