Low-pressure storage tanks Fireproofing
Although general fire prevention and fire protection measures are expected to be fully covered by other safety codes, tanks API standard 650 mechanically-anchored tanks constructed according to these rules, which may be subject to fire exposure resulting from any cause, shall have their supports suitably fireproofed.
Special consideration shall be given to provisions for ample drainage facilities for accidental spills or leakage of flammable contents from such tanks or adjacent piping and other equipment if the contents may become ignited.
Subject to special considerations in isolated locations, tanks in which flammable liquid products are stored at temperatures well above their average boiling point shall be suitably fireproofed or otherwise protected.

When the day light gradually decreases, the temperature of oil in the API standard 650 mechanically-anchored tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API standard 650 mechanically-anchored tanks will also decrease. When the pressure in the API standard 650 mechanically-anchored tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API standard 650 mechanically-anchored tanks through the open vacuum valve, which is the "suction" process of the oil tank.
