Question 1108 Deck General

The correct answer is A) explosion proof. An explosion-proof enclosure is designed to withstand the ignition of a flammable gas or vapor inside the enclosure, and to prevent the transmission of any flame that could ignite the surrounding flammable atmosphere. This type of enclosure is required for electrical equipment used in hazardous locations where flammable gases or vapors may be present, as per safety regulations. The other options are incorrect because: B) a flame proof screen is not the same as an explosion-proof enclosure, as it is designed to prevent the passage of a flame but not necessarily withstand an internal explosion. C) a primary gas barrier is a different concept, referring to a physical barrier that prevents the passage of a gas, not an explosion-proof enclosure. D) a gas-safe enclosure is not a standard term and does not accurately describe the requirements for an explosion-proof enclosure.
