Relates to a portable hazardous environment warning system for delivering.

Working in confined spaces such as ships, freezers and manholes increases the number of harmful gases such as carbon monoxide (CO), nitric oxide (NO), and carbon dioxide (CO2) while reducing oxygen (O2). Accidents such as choking often occur.

In particular, ships have a lot of enclosed spaces due to their structural features. In order to prepare for harmful gases during work such as welding, the conventional technology is notified by buzzer or the like, or vibration is applied to the device by vibrating plate. The gas detector, which is indirectly informed by the operator, is installed and the work is performed.

However, due to the nature of the work, there are cases in which the operator cannot recognize the warning signal from the gas detector due to the noise and vibration of the work machine.

In addition, firefighters often fail to recognize hazardous levels of hazardous gases due to the noise generated during a fire at the fire site, and sometimes accidents occur.
