These enclosures are engineered to ensure that any hot gases produced during an internal explosion are cooled below the ignition temperature of the surrounding flammable atmosphere as they pass through the enclosure’s joints. Components that are not independently rated for hazardous locations can be installed inside these enclosures, allowing the complete assembly to achieve the required hazardous‑area rating. Certain exceptions apply regarding which components are permitted for installation.
