Question 1339 Deck General

The correct answer is B) filling to the maximum level indicated on the liquid level gauging device. The amount of LFG (Liquefied Flammable Gas) that may be loaded into a tank is determined by the maximum level indicated on the liquid level gauging device. This ensures that the tank is not overfilled, which could lead to the release of gas or other hazardous conditions. The other options are incorrect because: A) the loading sheet may not always accurately reflect the maximum safe fill level, C) loading to within 1% of outage is too precise and may not account for all safety factors, and D) loading to within 10% of the safety relief valve setting is not the primary factor in determining the safe fill level.
