Safety Concerns
Since the introduction of the 3-ring system, variations in the design have raised safety concerns. For example, the move to mini rings and mini risers caused riser failures on some designs until riser strength was improved. The failure of some manufacturers to include stiff riser inserts and other hard housing cable guides to allow the free movement of the cutaway cable when risers and webbing are twisted has caused difficulty in cutting away from malfunctions with riser twists or harness deformations. The tolerance in the manufacture of the fabric risers and their connection to the rings is critical in maintaining the mechanical advantage of the 3-ring system and this has been compromised in some designs. Reversed risers placing the rings under the risers has prevented the rings moving freely and releasing under some cutaway scenarios.

Famous quotes containing the words safety and/or concerns:
“Once women begin to question the inevitability of their subordination and to reject the conventions formerly associated with it, they can no longer retreat to the safety of those conventions. The woman who rejects the stereotype of feminine weakness and dependence can no longer find much comfort in the cliché that all men are beasts. She has no choice except to believe, on the contrary, that men are human beings, and she finds it hard to forgive them when they act like animals.”
—Christopher Lasch (b. 1932)
“In what concerns you much, do not think that you have companions: know that you are alone in the world.”
—Henry David Thoreau (1817–1862)
