Summary
Regulators on several dive sites handling gas with greater than 25% oxygen were oxygen clean but contained incompatible materials. The flash distinguishes cleanliness from oxygen compatibility, discusses venting versus non-venting designs, and describes risk assessment and management of change for replacement, with limited retention of venting models under specified mitigations.

Summary
Regulators used with high-pressure oxygen gas were unsuitable because their materials and venting design did not meet oxygen-service requirements.
