Why is proper ventilation critical when using LPG or CNG systems?

Proper ventilation is essential when using LPG (Liquefied Petroleum Gas) or CNG (Compressed Natural Gas) systems primarily because it helps prevent the accumulation of flammable gas, significantly reducing the risk of explosion. Both LPG and CNG are highly flammable, and if these gases escape into an enclosed space without proper ventilation, they can concentrate to dangerous levels. This presents a serious safety hazard as even a small spark can ignite the gas-air mixture, leading to potential fire or explosion.

In areas where these gases are used, ensuring effective ventilation allows any released gas to dissipate safely into the atmosphere, thereby minimizing the chances of a hazardous situation. This is particularly crucial in maintenance, fueling, and operational environments where gas leaks may occur. Thus, adhering to proper ventilation guidelines is a critical safety measure to protect personnel and property from the risks associated with flammable gases.
