Additional measures beyond analyzing, labeling, and notox procedures to help prevent incorrect deco gas switches

This reminds me of something:
During the space race, NASA wanted a ballpoint pen that works in zero gravity and in extreme temperature ranges. The Soviets used a good ole pencil

Actually, that comparison doesn't work that well. The Fisher Space Pen turned out to be a huge success.

Btw, how's that magnetic sidemount system working?

The story about NASA spending money to develop a space pen while the Soviets simply used a pencil is a bit of a myth.

Initially, both NASA and the Soviet space programs used pencils in space. However, pencils weren't an ideal solution due to several issues. Graphite from pencils could break off and float in zero gravity, which posed a risk of damaging equipment or even being inhaled by astronauts and pencil shavings could be a fire hazard in pure o2 environments.

The Fisher Space Pen, invented by Paul C. Fisher, was developed independently by Fisher Pen Co. in 1965. NASA didn't fund its development but eventually purchased the pens after extensive testing. The Soviets also adopted the Fisher Space Pen for their space missions, buying them just like NASA.
