General Maintenance Action
Procedure
Accepted a Road Trip to travel to ZZZ (a non [company] city with no [company] ops) to replace 4 POBs (Portable Oxygen Bottle) and 1 IMK [Inflight Medical kit]. The replacement parts and my tools were loaded in ZZZ1 by Stores/Ramp. I was briefed to go through security and meet the crew at the airplane that was a rescue flight -no revenue passengers. After talking to crew; I was told they were waiting for clearance with a HAZMAT release to depart ZZZ1. Upon arrival in ZZZ; I was greeted by Contract Maintenance and we retrieved the replacement 4 POBs and IMK from the FWD cargo hold. We loaded the parts into the Contract Maintenance vehicle and he drove me to ramp area where Aircraft X was waiting. I replaced and secured the 4 POBs and 1 IMK. The POBs and IMK were made unserviceable and we packaged the unserviceable parts back into the original packaging and I signed off the write up in the log book and proceeded back to Aircraft X (the rescue flight aircraft). The Contract MX vendor and I loaded the old parts back into the FWD cargo hold. Aircraft X went on to perform a revenue flight to ZZZ2 and I was to return on Aircraft X reposition with the flight that was stranded in ZZZ for the previous day's medical emergency diversion. While the Captain was performing his pre-flight checks; I informed the Captain that the spent POBs and possibly IMK in FWD cargo hold are HAZMAT because of the clearance we had to get when departing ZZZ1 and that he may need to call and get the same clearance to depart ZZZ. The Captain acknowledged me and said 'thanks; that's good information.' I took my seat in the back and we flew to ZZZ1 with no interruptions. I was made aware that there was a concern with the way the parts were brought back on [date]. Cause: The pilot in command should have called for the necessary clearance/documentation if there was a need. I assumed that because the pilot continued the flight; there was no issue or that he received the proper clearance. The Captain was made aware of the HAZMAT parts before the entry door was closed and the air stairs pulled from the aircraft. Suggestions: MX is not trained on HAZMAT requirements; there should be some awareness or training for MX to know what is required. I wasn't sure; so I made sure the pilot was informed - because we had to have clearance when we left ZZZ1.
Technician reported the need of Maintenance Shipping/Handling training when dealing with HAZMAT requirements.
