GM Receives N95 Certification Under New NIOSH Public Health Emergency Process

General Motors has received N95 certification for the filtering facepiece respirators made at the company's Warren, Michigan facility. The approval was completed through the new public-health emergency process implemented by the National Institute for Occupational Safety and Health, part of the Centers for Disease Control and Prevention. 

In response to the urgent need to increase the inventory of NIOSH-approved respirators during the COVID-19 pandemic, the staff at NIOSH's National Personal Protective Technology Laboratory has worked tirelessly to quickly evaluate new domestic respirator applications for approval. These efforts are helping to increase the supply of available certified filtering facepiece respirators while ensuring that new respirators meet the protective standards workers need and expect from NIOSH-approved respirators. 

As defined by NIOSH, the term N95 refers to the filter class, not the respirator. However, many filtering facepiece respirators have an N95 class filter and many people refer to them as N95 respirators. A filtering facepiece respirator that filters out at least 95 percent of airborne particles during "worst case" testing using a "most-penetrating" sized particle is given a 95 rating.

Achieving an N95 rating required an entirely new manufacturing process with four separate stations to help create a tight seal around the user's face:

  • Station 1: Four layers of fabric are sandwiched together, tack-welded in place and then cut into rectangular "blanks"
  • Station 2: Blanks are loaded into a template that welds the outer perimeter as well as the pocket for the wire nose piece
  • Station 3: The wire nose piece is inserted, the blank is folded horizontally and a sonic weld in the shape of a hockey stick is installed from the nose to chin
  • Station 4: The excess material is trimmed

To expedite the launch of the N95 line, GM repurposed sonic welders from the Brownstown Battery Assembly plant. These sonic welders were previously used to form sub-assemblies in the Chevrolet Volt's battery packs. For the N95 line, the equipment was updated with new templates to create the weld patterns needed for respirators.

After being trimmed to shape, the N95 masks follow the existing assembly process at Warren: ear bands are manually welded in place; completed masks are subject to a quality check; and then masks are cleaned, bagged and prepared for shipment.

As with face masks, GM will donate some of the N95 respirators to frontline workers. To date, the Warren facility has delivered more than 4 million face masks and 230,000 face shields to frontline workers.
