Can all the equipment and instruments around areas with open flames be non-explosion-proof? Or how far away from an open flame area is explosion protection required?

Explosion protection is determined based on actual needs. Explosion-proof electrical equipment should be used only in environments with a risk of fire and explosion. The specific areas at risk of combustion and explosion are specified in GB50058.

GB50058 mentions that an open flame may allow it to be possible to avoid designating an explosion hazard area, but the wording is rather vague. In practice, for project-related open-flame equipment, it is not considered a hazard source, with a range of approximately 1.5 meters

Areas with an open flame are not necessarily explosive areas either
