Detailed description of the use of explosion-proof walkie-talkie

Explosion-proof walkie-talkies are specifically designed to operate safely in potentially explosive environments. Unlike regular consumer-grade walkie-talkies, these devices are not built to withstand explosions, but rather to prevent them from occurring. They are engineered to minimize the risk of sparks or heat that could ignite flammable gases or dust.

1. After two years of continuous use, it is essential to return the explosion-proof walkie-talkie to the manufacturer for retesting and re-evaluation of its explosion-proof rating. Over time, wear and tear can reduce the device's safety level, increasing the risk of accidents if not properly maintained.

2. Never replace batteries or other components in a hazardous area. Sparks generated during disassembly can lead to fires or explosions. Even if the device has passed an explosion-proof certification, avoid exposing the accessory connectors when used in dangerous environments. If not in use, always cover the connector with a protective dust cap to prevent accidental exposure.

3. Do not attempt to disassemble or modify any explosion-proof certified product (such as those tested by Shanxi Jizhou Electric). Any unauthorized changes to the internal structure may compromise the device’s safety and invalidate its explosion-proof certification. Only authorized personnel at certified facilities should perform any modifications.

4. Always turn off the power switch before charging the device. Avoid making calls or transmitting signals while charging, as this can cause damage to internal components or even lead to battery overheating and failure.

5. When using the device, never remove or bend the antenna. The antenna is a critical part of the radio’s performance and safety design. Damaging it may affect signal quality or create potential hazards.

6. Never short-circuit the battery’s positive and negative terminals. Each explosion-proof walkie-talkie is marked with an explosion-proof symbol, indicating it has passed rigorous testing. This mark also includes information such as the hazardous environment classification, the required Motorola battery model, user manual number, and temperature code. Explosion-proof models are typically certified by organizations like the Factory Mutual Research Corporation (FM). Common classifications include IS/I (Intrinsically Safe), Class I, II, III Div 1, Group CDEFG, and NI (Non-Incendive) Class I Div 2, Group A.

7. The temperature code is usually T3C. IS stands for Intrinsically Safe, while NI refers to Non-Incendive. To ensure maximum safety, always use explosion-proof radios in accordance with their specified operating conditions. The explosion-proof label must be affixed by the manufacturer before shipping. It is strictly prohibited to "upgrade" or alter an explosion-proof device elsewhere and then attach an explosion-proof label without proper certification.
