From the study guide
Occupational safety in the appliance service trade is governed by the principle of hazard identification and risk mitigation. As a technician, you are responsible for maintaining a safe work environment not only for yourself but for the customer and their property. Understanding the hierarchy of controls—elimination, substitution, engineering controls, administrative controls, and PPE—is essential for passing the Red Seal exam. Failure to adhere to these standards can lead to electrical shock, chemical exposure, or mechanical injury, all of which are preventable through rigorous safety protocols.
