Procedure
I went to retrieve a pressure gauge for the Aircraft X oxygen system and went into supply. The drawer I opened was in location cabinet XYZ for the pressure gauge. I found the gauge I needed and when I went to close the drawer I saw another gauge there that is used for the hydraulic reservoir cap with gauge attached in the same location as a gauge we use for oxygen. This is a major safety concern with petroleum products like hydraulic fluid being near oxygen tooling and equipment can cause combustion in the right conditions.The oxygen equipment needs to be segregated from ANY hydraulic or petroleum product at all times.
Technician reported discovering oxygen  gauges intermixed with hydraulic gauges in the company tool room in the same drawer.
