Gas detection systems

Gas signalization in underground garages in public, admin buildings and shopping malls

Do you know, that in the underground garages there is a very high risk of accumulation of dangerous gasses such as CO, propane-butane, methane and others?

The high concentration of many motor vehicles in such closed spaces creates the premise of accumulating large amounts of CO in the air, which is a poisonous and dangerous gas for humans. Moreover, the automobiles with built-in gas burning systems pose a threat for causing an accumulation of propane-butane and methane gasses, which can cause suffocation or explosion.

Solving the task of ensuring the safety in such buildings is possible thanks to the modern gas signalization systems. A typical such system usually consists of specialized sensors, which react to a certain percentage of different types of gasses and a central control panel. The central station has the task to provide audio and/or visual indication and to also switch the work mode of a ventilation system, if the gas concentration reaches a dangerous level.


Industrial applications of gas signalization systems

One industry which frequently uses gas signalization systems is the mining industry. There, the risks of gas-related incidents are high, because of leaks and explosions of methane gas. Methane is found in nature, it has no color and it can cause suffocation and explosion. The gas leaks through cracks on the rocks and it can accumulate in dangerously high concentrations in caves and niches of the underground mining tunnels.

For example, in 1963 in Japan 20 people died in a methane explosion and 438 more died later from CO poisoning. In the same way on March 19th, 2007, in the Ulyanovska mine in Russia 108 people lost their lives. The gas signalization system can provide an irreplaceable role in preventing such heavy accidents from happening, by offering prompt notification for gas accumulation and on-time notification of the mine management personnel, as well as signal for turning on the proper ventilation system to clean up the air in the mine.


Ensuring gas safety in private homes and apartment buildings

The propane-butane gas is one of the cheapest energy sources, which have established a strong presence in our daily lives. The gas is widely used also in powering motor vehicles. By specification it is an explosive gas, which is heavier than the air and it accumulates in the low sections of the volume of a room and any similar premise, where there is a central gas supply system or just gas containers. Propane-butane explosions unfortunately are frequent incidents. Fore example, in Venezuela, propane-butane gas explosion leveled a 14-story building.

In order to prevent such accidents from happening, the gas signalization system manufacturers make economical devices, which can offer reliable gas signalization for concentrations above the dangerous 2% level of the volume of the premise.
