Aircraft Equipment Problem Less Severe
General Maintenance Action; General Flight Cancelled / Delayed
Aircraft; Human Factors
During our Safety Check; my First Officer discovered that is O2 mask would not test properly. He removed the mask and discovered that some type of adhesive had been placed on the flow control knob. When the mask was removed the O2 flowed continuously due to the 'press to clear' button being glued in. The flow continued until the door was closed and the 'press to test PB was reset.' We lost approximately 100 PSI of O2 in the process. Maintenance was called; write up was entered in can; and flight was delayed. Mechanics were unable to rotate the flow control knob or make the PB function properly. Additionally; I had to write up burned out light bulbs after a LC2 check. The mask would not have functioned properly in flight. I suggest we get some experienced mechanics. Stop 'pushing' mechanics.
A CRJ700 First Officer found that his O2 mask had an adhesive on the flow control knob causing the O2 to flow continuously when O2 compartment doors were open.
