3-6 Collecting And Burning Noncondensible Gases

Because these gases are toxic, great care must be taken in the design and construction of systems to handle these gases. Gas leaks, especially in enclosed areas, must be avoided. Adequate venting must also be provided, such that when there is an upset condition causing the gases to vent, the gases are released in a safe area and in a safe manner.

Fire Hazards and Fire Protection - Gas-fired Power Plants ...

Gas-fired power plants are growing in popularity. Canada has already begun to phase out coal-fired power plants in favor of gas-fired power plants. Gas is less expensive and a cleaner form of fuel than coal. However, with a surge in gas-fired power plants being built, a closer look needs to be taken on the fire hazards within these plants.
