Status: active
Page Count: 27
scope:

This standard shall apply to all hypobaric facilities in which humans will be occupants or are intended to be occupants of the hypobaric chamber.

This standard shall not apply to hypobaric facilities used for animal experimentation if the size of the hypobaric chamber does not allow for human occupancy.

Purpose.

The purpose of this standard shall be to set forth minimum safeguards for the protection of personnel involved in the use of hypobaric facilities, when operated at pressures less than 760 mm Hg [101.3 kPa; 1 atmosphere absolute (ATA)].

The purpose shall also be to offer guidance for rescue personnel who are not ordinarily involved in the operation of hypobaric facilities, but who would become so involved in an emergency.

The purpose shall also be to provide minimum standards for the design, maintenance, and operation of hypobaric facilities.

Hypobaric chambers shall be classified according to the following criteria:

(1) Class D - Human rated, air atmosphere not oxygen enriched

(2) Class E - Human rated, oxygen-enriched atmosphere (partial pressure of oxygen is above 0.235 ATA)
