Question 2248 Deck General

The correct answer is D) 10 percent. According to the regulations governing oil transfer operations, each pressure gauge used must be accurate to within 10 percent of the actual pressure. This ensures that the pressure readings are sufficiently reliable for safely conducting the oil transfer. The other options, such as 1 percent, 3 percent, or 5 percent accuracy, would be more stringent requirements that are not specified in the regulations for this type of operation.
