By looking at the logbook I noticed that the airplane just came from C-Check and that the flight was going to be the first revenue flight. We conducted a detail pre-flight and safety check and discovered that the Captain's side flashlight was inoperative (INOP) and that the cockpit oxygen bottle was in the' CLOSE' position. I called the local Mechanic and he fixed the problem with the flashlight. I informed him of the oxygen bottle position and told him that I opened the valve. The C-Check was done in ZZZ by an EMBRAER Repair Station. I don't know if this is an ongoing issue or a rare mistake. Either way I consider this to be a serious issue that can result in a dangerous situation if for some reason oxygen is required during an emergency and the oxygen bottle valve was closed. It would have been easy to miss the oxygen bottle condition under the circumstances (First Officer in IOE; first flight of the day with an early XA:50 AM show and time constraints to get the airplane out on time). The oxygen was serviced the day before per the logbook. Please look into this before something bad happens. Maintenance personnel have to follow established maintenance procedures and ensure completion of each step in the Maintenance Manual/Task Card at hand. Some kind of note should be left in the cockpit notifying the flight crew that the airplane underwent Heavy Maintenance previous to that flight. Crew must check all safety equipment and thorough preflight after any service/maintenance was done on the airplane prior to their flight. High workload.
Captain notices the crew oxygen (O2) bottle handle was in the 'Close' position during their detailed pre-flight safety check of an EMB-145 aircraft. Logbook indicated the aircraft had just been released from a Heavy Maintenance Visit.
