National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Respirator Tolerance.

PB92206085

Publication Date	1992
Personal Author	Harber, P.
Page Count	27
Abstract	Respirator and personal factors affecting tolerance to respirator use were identified. The project evaluated interrelationships among various respirator loads, exercise level, personal characteristics, ventilatory, sensation, respiratory control, and subjective effects. Normal volunteers, industrial workers, and persons with mild respiratory impairment were used in laboratory and field tests on respirators. Flow resistance, dead space and pressure biasing were measured in response to respirator load. Respiratory pattern adaptation was investigated. Personal factors affecting tolerance were studied, including psychophysical load scaling sensitivity, and self rated tolerance. The author concludes that the safe and effective use of respirators necessitates attention to many factors, including personal characteristics and subjective effects. Human panel testing appears to have a major role in the objective evaluation of respirators.
