Mask Retention Systems
Medical oxygen masks are held in place by medical personnel or the user by hand, or they may be fitted with a light weight elastic headband so the mask can be removed quickly. Full-face masks are secured by several straps. Tightly fitting oxygen masks are secured at four points by two head straps. Aviators’ masks are often equipped with “quick don” harnesses that allow those in pressurized aircraft to rapidly don the masks in emergencies. Military aviators’ oxygen masks are secured to flight helmets with quick-release systems.

Famous quotes containing the words mask, retention and/or systems:
“But today I set the bed afire
and smoke is filling the room,
it is getting hot enough for the walls to melt,
and the icebox, a gluey white tooth.

and they are just for you....”

“Unless a group of workers know their work is under surveillance, that they are being rated as fairly as human beings, with the fallibility that goes with human judgment, can rate them, and that at least an attempt is made to measure their worth to an organization in relative terms, they are likely to sink back on length of service as the sole reason for retention and promotion.”
—Mary Barnett Gilson (1877–?)
“Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
—Ralph Waldo Emerson (1803–1882)
