These devices are typically installed in or near explosive environments, and radiation may pass through them. Due to the inherent characteristics of radiation, it may ignite the surrounding explosive environment. Additionally, the presence of absorbers can significantly affect ignition.

The country has clear explosion-proof testing and certification standards for electrical equipment used in potentially explosive environments. For optical radiation equipment used in potentially explosive hazardous environments, the national GB/T3836.22-2017 also has corresponding explosion-proof technical requirements.
