Which of the following would most likely require special knowledge of hazardous locations? a. service work b. residential wiring c. commercial wiring d. industrial wiring

## Step1: Identify the context of hazardous locations<br />### Hazardous locations are areas where there is a risk of fire or explosion due to the presence of flammable gases, vapors, dust, or fibers. These environments require special precautions and knowledge to ensure safety.<br />## Step2: Analyze each option in relation to hazardous locations<br />### <br />- **Service work**: Typically involves general maintenance and repair, not necessarily in hazardous locations.<br />- **Residential wiring**: Generally does not involve hazardous locations as homes do not usually contain flammable materials in significant quantities.<br />- **Commercial wiring**: While it can involve more complex systems than residential wiring, it still typically does not involve hazardous locations.<br />- **Industrial wiring**: Often involves environments with machinery, chemicals, and processes that could create hazardous conditions, requiring specialized knowledge.<br /><br />## Step3: Determine the most likely scenario<br />### Industrial wiring is the most likely to require special knowledge of hazardous locations due to the nature of industrial environments.<br /><br />#
