What is the risk associated with allowing waste gases to accumulate in an enclosed space when using the SGNSC?

The accumulation of waste gases in an enclosed space when using the SGNSC (Solid Fuel Gas Generating System) poses serious risks primarily due to an increase in the concentration of harmful gases. Among these, the risk associated with excess oxygen is critical. When oxygen levels are elevated, there is a higher probability of fire or explosion, particularly in the presence of flammable materials or conditions that can ignite a fire.

This is important because when waste gases accumulate, they may not only contain excess oxygen but can also limit the effective ventilation needed to maintain safe conditions. The presence of significant amounts of oxygen, combined with combustible materials, can lead to dangerous situations, making this a priority concern in managing enclosed environments.

While elevated levels of carbon monoxide, nitrogen poisoning, and general discomfort and irritation are relevant hazards in the context of gas accumulation, they do not pose the same immediate and catastrophic risk of fire or explosion that excess oxygen does in an enclosed space.
