Fatigue or drowsiness | Gas affects oxygen levels and alertness |
Irritation in eyes/throat | Possible buildup of contaminants |
Shortness of breath | Especially for those with respiratory issues |
Pets acting unusually lethargic | Animals are often more sensitive to gas leaks |

Tool/Device | Funksjon |
---|---|
