The cap lamp and underground digital communications systems supplier received IECex and ATEX approvals for Polaris, including Group II and M1Certification.

The company is still pursuing MSHA approvals for North American markets.

The approvals allow the products to be sold into Europe, which recognises ATEX certification, as well as other countries, including Australia, which recognise IECex approval.

While NLT has received IEC 62013 as a minimum requirement, it has also obtained additional certification to M1, a first for the company, as it allows the user to continue using the lamp even after methane has been detected.

Previously, the lamp and miner needed to exit the mine immediately.

“This is useful for mine rescue workers and those who remain in, or enter the mine to correct the problems that caused the high gas levels,” NLT said.
