The principal hazard to personnel when using a diesel engine fuel nozzle tester is_______________.
AI Explanation
The correct answer is D) blood poisoning.
The principal hazard to personnel when using a diesel engine fuel nozzle tester is the potential for blood poisoning. Diesel fuel can be highly toxic if it comes into contact with the skin and can lead to serious skin infections and blood poisoning if not properly handled. The fuel nozzle tester is used to check the operation of the fuel injection system, which involves direct contact with the diesel fuel, presenting a risk of skin exposure and subsequent blood poisoning.
The other answer choices are incorrect because they do not represent the primary hazard associated with using a diesel engine fuel nozzle tester. Electrical shock (A) and explosion (C) are not the main concerns, and toxic fumes (B) are not as significant a risk as the potential for blood poisoning from skin contact with the diesel fuel.
