Days before the 12th anniversary of the 9/11 terrorist attacks, the New York Times published an article about respirators. This protective equipment was intended to protect response and recovery workers at Ground Zero, but often failed to do so because of discomfort, inadequate training, or unsuitable equipment. Thousands were exposed to airborne contaminants, and many have become sick.

In the years since, federal agencies and equipment manufacturers have been working on developing new certification standards for respirator masks and assuring they can be used by workers responding to different emergencies, from disease outbreaks to accidental nanoparticle releases. Anthony DePalma reports:

Among the lessons learned from ground zero was that reusable respirators from different manufacturers used filters that weren’t interchangeable, greatly impeding flexibility. It was as if there were a different size spark plug for every make of car.

So the national laboratory, working with responders and manufacturers developed a set of standards, known as C.B.R.N. for chemical, biological, radiological and nuclear hazards. To win C.B.R.N. certification, respirators must accept filters and cartridges with the same 40-millimeter thread, similar to the base of a standard light bulb.

Another lesson from ground zero was that responders were reluctant to wear masks for long because it was too hard to speak or to be understood while wearing one. The new equipment must also meet tougher intelligibility standards for communication.

Besides conducting research and testing products, the national laboratory inspects respirator manufacturing operations around the world and conducts surveillance to ensure that certified products continue to meet United States government standards.

DePalma also notes that respirator testing had been based on face shapes and sizes from a sample of Air Force cadets measured in the 1960s. Researchers at the National Personal Protective Technology Laboratory are developing a new set of face, head, and neck standards based on a more up-to-date and diverse sample.
