Question: 1 / 400

What potential hazard can methane gas in confined spaces cause?

Explosions

Burns

Fires

Asphyxiation

Methane gas in confined spaces primarily poses a significant risk of asphyxiation. When methane accumulates in an enclosed area, it can displace oxygen, creating a hazardous environment for anyone present. Since humans require oxygen to breathe, a lack of oxygen can lead to impaired cognitive function, unconsciousness, and ultimately death if exposure persists.

In addition to asphyxiation, methane is also flammable and can contribute to explosions or fires, but in the context of confined spaces, the immediate and life-threatening risk posed by the depletion of oxygen makes asphyxiation the most critical concern. Understanding this hazard is essential for home inspectors, especially when evaluating buildings with potential methane presence, such as those near landfills or certain agricultural areas, where methane can accumulate in basements or other confined areas.
