## Questions & Answers

**Q: Can this detect LPG gas leak ?**
A: Carbon monoxide is a very different gas to natural gas, often created when fuel is burned in the presence of low levels of oxygen. As carbon monoxide is an entirely different composition to natural gas, carbon monoxide detectors will not detect natural gas leaks.
