Question: 1 / 400

Which of the following best describes flameproof equipment?

Prevents electrical overloads

Contains any explosion within the device

Flameproof equipment is specifically designed to contain any explosions that may occur within the device, preventing the propagation of flames or pressure waves to the surrounding environment. This means that if an explosive atmosphere is present, any ignitable gases or vapors that enter the equipment would be contained in the event of an internal explosion. The robust construction and sealing of the housing ensure that the flames do not escape, thus protecting the surrounding area and reducing the risk of potential hazards in environments where flammable materials may be present.

This characteristic is crucial in hazardous areas, as it allows for the safe operation of electrical devices while maintaining the integrity of the surrounding atmosphere.
