Questions and answers
What should an engineman do before operating a piece of equipment?
You must never attempt to operate a defective piece of equipment. (paragraph 1-16)
How must unsafe conditions be handled in the engineering plant?
You must report all unsafe conditions to the space and/or plant supervisor. (paragraph 1-16)
What are soundings used to measure?
Soundings are taken for the purpose of measuring the amount of fuel in a tank or the amount of water in that fuel. (paragraph 1-18)
What must a diesel fuel system control during injection?
A fuel system must also control the rate of injection. (paragraph 8-4)
Why is proper fuel atomization important?
Proper atomization helps to start the burning process and ensures that each minute particle of fuel will be surrounded by particles of oxygen with which it can combine. (paragraph 8-5)
