Final answer:
If a flammable gas is accidentally released in a confined area, the consequence can be more severe than if the flammable gases are not confined.
Step-by-step explanation:
True. If a flammable gas is accidentally released in a confined area, the consequence can be more severe than if the flammable gases are not confined. This is because when a flammable gas is confined, it can build up in concentration and create a more explosive environment. In contrast, if the flammable gases are not confined, they disperse more quickly and their concentration decreases, reducing the risk of explosion.
