What makes CRT monitor disposal dangerous for a technician who is handling the disposal?
- potential breathing hazards
- potential explosive materials
- potential residual high voltage
- potential health-damaging chemicals
Explanation: CRT monitors do contain lead, barium, and rare earth metals that can be dangerous to the environment if not disposed of properly, but the danger to the technician is in the high voltage levels that can be stored even after powering off the monitor and disconnecting the power cord. A technician might be disposing of a CRT monitor that has the cover ajar or removed and be exposed to the high voltage.
