The Strata Worldwide Breathable Air Component used in its portable Fresh Air Bay mine refuge chamber has received U.S. Mine Safety and Health Administration (MSHA) approval.

The Fresh Air Bay Breathable Air Component is one of a series of design modifications Strata is making to the Fresh Air Bay design in order to meet MSHA’s new chamber regulations as specified in Part 7 of Title 30 Code of Federal Regulations.

The approved Breathable Air Component is an element of the proprietary breathing air system standard in all Strata Fresh Air Bays. This breathing air system provides chamber occupants with 96 hours of breathable air in the event of an emergency that prevents escape from the mine.

Fresh Air Bay is an inflatable mine refuge chamber that is deployed in post-accident situations to provide miners trapped underground with breathable air and other life sustaining provisions while they await rescue.
