A one-hour, 4.5-pound, self-contained emergency breathing apparatus tested and approved by the National Institute for Occupational Safety and Health and the Mining Enforcement and Safety Administration for underground coal mines is described. The unit could be used by miners to replace the existing self-rescuers. It provides a minimum of one hour of breathable atmosphere during escape from a mine with contaminated or oxygen-deficient atmosphere. The report contains an introductory summary of the contract requirements and accomplishments of the development program; a description of the apparatus (PBA), including the functions of the components; deployment procedures, use of the PBA on an unconscious person and PBA storage life; design and analysis; laboratory tests; PBA man tests, including test equipment description, safety considerations, and test results; and NIOSH tests.
