Flameproof equipment refers to an apparatus designed to ensure that internal ignition within a flammable atmosphere will not transmit outside the protective enclosure. In other words, flameproof equipment prevents the ignition of surrounding flammables in the hazardous area. Flameproof is a preferred protection method when electrical equipment potentially contains high energy arcing or sparking components in standard operation. Furthermore, these high-energy components form explosions that are difficult to avoid.

Flameproof is one of many explosion protection techniques extensively used for light fittings, JBs, and motors in hazardous areas. Moreover, the IEC certifies protective equipment and the local IS (Intrinsically Safe) standards govern usage.

Flameproof Certification

To be certified as an explosion or flameproofed protection, the enclosure must be strong enough to contain explosive reactions. Additionally, certified protection must withstand the internal pressures generated without fracturing or distorting to prevent propagation. Products undergo testing for flame and explosion protection, like several actual explosions within simulated environments, to become officially certified.

The terms ‘explosion-proof’ and ‘flameproof’ are often interchangeable. Although there are subtle differences, engineers and the safety market generally use both terminologies to refer to the same thing. For instance, a piece of electrical equipment designed for use in a hazardous area through a heavy-duty enclosure.

The purpose of enclosures is to protect the surrounding environment outside by enclosing sparks or explosions within itself. And, the protective enclosure itself must also be heat resistant to high degrees so that fires do not escape the barrier. Thus, flameproof casing serves as a safety measure to prevent malfunctioning equipment from generating sparks and igniting any external flammable gases in hazardous environments.
