"Vented" refers to the process of allowing air, gas, or liquid to escape from a confined space. This can occur in various contexts, such as in vented clothing, which is designed to enhance breathability by incorporating openings that allow moisture and heat to escape. In mechanical systems, venting is crucial for safety, as it prevents pressure buildup that could lead to explosions or equipment failure. For example, vented gas appliances have exhaust systems that direct harmful gases outside, ensuring safe operation and reducing the risk of carbon monoxide poisoning.
