FLAMEPROOF TELEPHONE 110DB SOUND LEVEL 
An FLP (Flameproof) Telephone is a communication device designed for use in hazardous environments where explosive gases, dust, or other combustible materials are present, such as chemical plants, oil rigs, or mines. It is built with a rugged, explosion-proof metal enclosure (often aluminum alloy), a corrosion-resistant design, and features like a durable handset with an armored cord, making it resistant to fire, water, and corrosive substances. These telephones ensure reliable voice communication without posing a risk of ignition to the surrounding atmosphere, meeting stringent safety standards for hazardous locations.
