min, and death within 30 min. Very high concentrations (e.g. 12800 ppm) causes
unconsciousness after a couple of breaths, followed by death in less than 3 min. [2] The
indoor dangerous sources are the leak source of CO, CO2 and CH4, which may be gas
tank or the fire site. The essential component of coal gas or nature gas is CO or alkanes
gas. The burning of chemical materials or decorative materials will emanate CO, CO2
and alkanes gas. The danger of these gases arising is from two aspects, one is the
toxicity of these gases themselves, the other side is that the accumulation of these gases
will easy be ignited. The position of gas tank or pipeline is usually fixed, so it is easy to
inspect, yet the fire site is random, and it will be difficult for inspection. [3] The danger
of the CO gas is the same as the LPG and others dangerous gas in the environment.
Gas detector is a gas detecting device. It only can detect if there is a gas leakage
or the leaking concentration. Meanwhile, the monitoring system is a system that is used
for displaying how much concentration of gas is in that place but viewing take place in
another remote computer, GSM networking or internet server. Therefore, monitoring
system give the advantages to users such that they can monitor the situation of the room
or the place where leakage occurrence may happened at safe distance continuously. .
1.2 Problem Statements
There are so many health issues related to dangerous gas in industrial area. Thus,
the atmosphere of a workplace should be regularly monitored and controlled in order to
maintain clean air environment. However, efforts in industrial air quality control have
been impeded by the lack of science-based approaches to identify and assess atmosphere
air quality and level of dangerous gas.
