Which description best fits an exhausted enclosure?

An exhausted enclosure refers to a specialized space designed to effectively manage and remove harmful substances such as fumes, mists, vapors, and gases from the environment. This is crucial in settings where hazardous materials may be present, ensuring that the air quality remains safe for individuals working in or around the enclosure. The primary purpose of this type of enclosure is to protect personnel from exposure to potentially toxic substances by incorporating appropriate ventilation systems that continuously draw out contaminants.

In contrast, the other options describe different functions or features. A room with general ventilation for gas containers does not necessarily have the targeted functionality of capturing harmful fumes or gases. A secure storage area for compressed gas containers emphasizes safety but does not directly address the need for capturing and removing fumes. Similarly, an environment for handling incompatible materials focuses on the safe management of substances that could react dangerously with one another, rather than actively exhausting harmful vapors. Thus, the correct answer highlights the specific role of an exhausted enclosure in enhancing safety through targeted removal of hazardous substances.
