Narrative:
While in the cockpit doing our preflight planning; the flight attendants brought to my attention that in all lavatories there were seals placed across all oxygen panels. Obviously this needs to have immediate attention. Most flight attendants would not have checked or caught this; so how many airplanes are flying around with their oxygen panels sealed? Supplemental information from acn 645752: it is my opinion that the oxygen panel would not deploy if needed. Flight attendant was instructed to break the seal prior to pushback and a short note was sent to maintenance control. Is this happening in other aircraft? Is this correct? Callback conversation with reporter acn 645753 revealed the following information: the report was also filed with the company; but there had been no feedback to the reporter.
