In explosive environments, explosion-proof electrical equipment must be used, accompanied by an effective explosion-proof certificate; electrical equipment destined for use in coal mines must obtain a coal safety certification prior to being sent underground, as required by our relevant regulations. Outside of the coal industry, sectors such as petrochemicals, metallurgy, and other industrial fields must also employ explosion-proof electrical equipment to ensure production safety and prevent explosion incidents.
The current safety production situation in our country remains extremely serious, with explosion accidents occurring from time to time. It is urgent to strengthen safety production efforts across all industrial sectors. For coal mining enterprises, selecting reliable explosion-proof equipment is one effective means to prevent explosion accidents.

What is the Coal Safety Certification?
Coal Mine Mark Certification (abbreviated as MA, KA Certification) is a mandatory certification implemented by the Coal Mine Safety Mark Office for products used in coal mine underground.
Products listed in the safety certification catalog for mining products must obtain a certification certificate. Individuals and organizations are prohibited from selling, purchasing, or using mining products included in the safety sign management catalog without obtaining a safety sign.
The manufacturer of the product must go through several steps to apply for a safety mark, including filling out an application form, preliminary review and qualification registration, evaluation, and issuance of the certificate.
