What are the requirements for obtaining Coal Safety Certification and Mine Safety Certification?
Coal safety certification and mine safety certification are mandatory certifications for mining products and equipment.
Coal safety certification is for equipment used in coal mines, while mine safety certification is for non-coal mine equipment.
Certificates are all applied for, reviewed, and issued at the ANSI Center. Validity is for 5 years, with annual supervisory assessments required.
Applying for both Coal Safety Certification and Mine Safety Certification requires passing two stages: product testing and factory inspection.
Applicants must possess design and R&D capabilities and provide complete product design drawings.
And require an in-house production facility. Some products can also apply for coal safety and mine safety certifications through the OEM process.
