This article points out some very important facts. One not mentioned in this article is that we have staff members qualified to perform this service.
Oxygen cleaning of scuba equipment requires a well-planned, tested, and effective procedure consisting of seven essential steps.
1️⃣ Initial inspection to determine whether it can be cleaned and how
2️⃣ Initial mechanical cleaning to remove any visible dirt or contamination, followed by degreasing using a cleaning agent suitable for oxygen service
3️⃣ Flush using clean, potable water to remove all cleaning agent residue.
4️⃣ Dry using oxygen compatible air or other gas, which must be oil-free.
5️⃣ Final inspection for any remaining surface contamination, which can include any or all of the following: Use a bright white or UV light in a darkened inspection area, use a fine water spray on the components and look for instant beading, or wipe the cleaned area with a clean, lint-free, white cloth and inspect the cloth with a white or UV light (this works well for cavities and hard-to-view surfaces)
6️⃣ Preserve the cleaning by immediately packaging or otherwise protecting the components from contamination.
7️⃣ Document the process in writing, and issue documentation for each item cleaned with a certificate, report, or sticker recording the technician, date, cleaning agents, and inspection methods.
Only properly trained, competent technicians should perform oxygen cleaning. Some industries require laboratory validation of cleanliness, but this is not usually the case in the diving industry, as a well-designed process will effectively remove any readily flammable contaminants.
*No amount of cleaning and inspection can guarantee completely safe equipment. Proper oxygen cleaning can help ensure there is no combustible fuel and increase confidence in your safety.
