Things that keep us safe are always worth reviewing.

Misuse of tank-to-regulator washers accounted for a number of incidents where leaking oxygen caused fire or explosions.

In a nutshell – NIOSH (National Institute for Occupational Safety & Health) states: Do not reuse the “crush” washers that usually come free with each refilled O2 tank. Whenever possible, use the “metal-bound” sealing washers that come with new regulators and are designed for re-use. If the original washer is lost or damaged, you should replace it with an equivalent washer.

See the original FDA and NIOSH Public Health Notification for further clarification.
