Structure and features of explosion-proof walkie-talkies

Explosion-proof walkie-talkies are all equipped with FM/ATEX certification labels to indicate that the product has been certified by the association and can be used in specific hazardous gases. At the same time, the label will clearly indicate the hazard level/branch/group and the accessory number of the battery that must be used.

Since the contact sparks generated when disassembling the walkie-talkie can cause explosions or fires, users cannot replace batteries and other accessories in hazardous environments during the use of explosion-proof models. Even for products certified by explosion-proof testing agencies, the accessory connectors cannot be exposed when used in hazardous atmospheres. If the user does not need to use the accessory connector, it should be tightly covered with a dust cover.

Explosion-proof walkie-talkies are different from civilian walkie-talkies. In addition to high performance in special environments, they also need other advanced functions. It can achieve crisper and louder voice quality, and can maintain unimpeded communication even in noisy environments.

Since ordinary mobile phones and other communication tools may generate arcs or electrostatic discharges when transmitting, they can even cause fires under certain conditions. Chapter 4, Section 4 of the "China Petroleum Gas Station Management Standards" clearly stipulates that it is strictly forbidden to use ordinary communication tools at the gas station and oil tank area.

In such a high-risk environment, professional explosion-proof communication tools must be used for communication. It is developed for harsh environments and environments with dangerous flammable gases or dust, such as petrochemical, coal mining, chemical, thermal power, food processing and other industries.
