What safety precaution is associated with removing the cover of a temperature switch?

• A. Risk of mechanical failure
• B. Electrical shock hazard
• C. Thermal burn hazard
• D. Chemical exposure hazard

Answer: (B)

The correct answer focuses on the electrical shock hazard that can arise when removing the cover of a temperature switch. When accessing the internal components of a temperature switch, there's a possibility that live electrical parts may be exposed. If proper safety precautions are not taken, such as ensuring that the power is turned off before accessing the device, there is a significant risk of electric shock. This is especially critical when working with devices that are connected to high voltages or currents. The other options, although they represent valid concerns in different contexts, do not specifically pertain to the primary risk associated with removing the cover of a temperature switch. Mechanical failure can occur but is less about immediate safety when opening the device. Thermal burns are a concern with components that may be hot, and chemical exposure would not typically arise from simply removing the cover of a standard temperature switch unless it is part of a specific industrial application involving hazardous materials. Hence, electrical shock hazard is the most relevant safety precaution in this scenario.
