Configuration A design described by its dimensions, components, method of assembly, and
materials of construction. Supplied-air suit configurations are tested in a suit test facility.
Department of Energy Respiratory Acceptance Program (ERAP) A program set up, based
primarily on respiratory protection performance, to accept or reject supplied-air suits that are used
to protect DOE contractor and federal employees from exposure to harmful atmospheres and
Helmet That portion of a supplied-air suit that surrounds the head and is intended to keep
contaminants from entering a wearer's breathing zone.
Respiratory Advisory Committee (RAC) The DOE Respirator Advisory Committee is
composed of persons who are knowledgeable in the field of respiratory protective devices. This
committee is composed principally of representatives from the field and headquarters elements, but
may also include industry, academic or other government representatives. The Committee provides
peer review of the test procedures and quality assurance.
Suit Tester An individual who voluntarily agrees to put on a supplied-air suit and perform certain
tests in this proposed supplied-air suit. These individuals must complete the physical and training
qualifications as specified in the current OSHA respirator standard (29CFR1910.134)
Suit Test Facility (STF) A testing facility capable of evaluating supplied air suits according to
the guidance provided in this standard. Preferably, this facility is organizationally independent of
the organization seeking the test.
Supplied-air suit A supplied-air suit, as discussed herein, is considered ventilated protective
clothing protecting the respiratory tract and skin of the wearer against harmful atmospheres and
radioactive contamination. The air may be supplied only to the head portion but preferably is
distributed to other parts of the suit. The supplied-air suit consists of the protective covering for the
body of the wearer; the breathing air hose; and other attachments, accessories, and auxiliary items
such as breathing tube, couplings, airflow-control valve, airflow meter, air-pressure gauge,
communications equipment, gloves, boots, cooling devices, and shoe coverings. These supplied-air
suits are never to be used in Immediately Dangerous to Life or Health (IDLH) or oxygen-deficient
Test Operator The individual who directs the conduct of the tests specified in this standard.
