Скачать или смотреть Mask Webinar Contained Lots of Discussion But Not Much Disagreement

Association presidents, E.R. doctors, researchers and suppliers discussed the potential to quickly fit everyone with tight fitting and efficient masks. There was general agreement that more efficient masks would make a huge difference in stopping COVID. There was surprising little disagreement on the availability of media and mask manufacturing.
There were, however, many views on how and if the regulatory, political, and social barriers could be breached. Dave Rousse of INDA explained how his non wovens association group had understood as early as March that some standard would be advisable for public masks. The initial discussion with NIST was around an N80 as opposed to an N95 mask. Subsequently INDA started working with ASTM. The result is a standard soon to be released which sets two efficiency levels. One is 20% or higher. The other is 50% and higher. When you consider that the virus is generally in larger particles or drops than used for the efficiency rating and that the effectiveness is the combined efficiency of masks on emitters and recipients these standards will greatly reduce COVID spread.

Eric Couch believes the new administration can be persuaded to champion the new ASTM standards. His concept is to keep it simple and to first persuade a small group of experts with influence who would then persuade the decision makers.

Eric recommends the use of multiple mask designs including one with flat filters and external braces. This design lends itself to quick scale up. Sabrina and Katherine Paseman have designed an external brace which is comfortable and tight fitting. it gives surgical masks the tight fit and efficiency of N95 masks.

Keith Dellagrotta and Jesse Chang have a program where a mask purchaser can use his mobile phone and select a mask which will provide a good fit.

Mcilvaine introduced a 5-step program starting with mask manufacturing quality control, distribution quality control, an ASTM or governmental minimum, a tested quality seal, and fit check.
