Question 202Motor Plants - 1st Asst/Chief70% to pass
Which of the listed items should be secured before performing any maintenance on a solenoid operated air start valve?
AI Explanation
The correct answer is A) Electric power and starting air.
Before performing any maintenance on a solenoid-operated air start valve, it is critical to secure the electric power and starting air supply to the valve. This is to prevent the valve from unexpectedly activating during the maintenance, which could lead to personal injury or damage to the equipment.
The other options are incorrect because they do not directly relate to the safe preparation for maintenance on the air start valve. Securing lube oil, hydraulic, or pneumatic systems may be necessary for other maintenance tasks, but are not the primary safety considerations for working on the air start valve specifically.
