CDC Will Test Seal on Influenza Masks

WASHINGTON (CN) - The Centers for Disease Control and Prevention plan to regulate the leakage of air or matter into air-filtering respirators used by safety workers and health care staff for disease outbreaks.

Currently, there is no assurance that the masks will keep disease and particulates out, without specific fit testing.

The Centers will propose general requirements for leakage testing and performance, to increase the likelihood that such users would obtain an adequate facepiece-to-face seal, and protection, in emergencies.

The masks also are used to filter particulates for those who work with coal, metals, dust, or other potentially hazardous aerosols.
