10.3.2.1. Offloading Hoses. For truck or tank car offloading areas, use 101-millimeter (4-inch)
lightweight, reinforced, vacuum-rated offloading hoses (see MIL-HDBK-1022A). Test per the
FREQUENCY: Prior to initial installation and as determined by the LFM supervisor and
local environmental requirements.
10.3.2.2. Issue Hoses. Truck fill stand, marine off-loading, and aircraft refueling hoses must
meet the standards of API 1529. Hydrostatically test to one and one-half times the dead head
(shutoff head) pressure of the system, not to exceed the maximum working pressure of the hose.
NOTE: Hydrostatic hose testing for real property installed equipment (RPIE) is a joint
operator/LFM responsibility, yet primary responsibility lies with the LFM shop foremen. The
LFM shop maintains hydrostatic test records and performs the test. Mutual arrangements for
hose testing by the refueling maintenance (RFM) shop is authorized and encouraged where
possible. Ground product hoses with working pressures less than 20 psi do not require pressure
FREQUENCY: Prior to initial installation and as determined by the LFM shop foreman,
local environmental requirements, and manufacturer's recommendation. When an API
1529 hose is delivered with a hydrostatic certification from the manufacturer, initial testing
is not required.
10.3.3. Storage Tanks.
10.3.3.1. Aboveground Field-Constructed Tanks.
10.3.3.1.1 Visual Inspection. Visually check the exterior of each tank for leaks, corrosion, or
irregularities such as tilting, settling, or out-of-roundness. Give special attention to seams
and anchor bolts. Maintain a waterproof seal at the tank chime-ring wall foundation
interface. Retain records in the LFM shop for five years. Scrape, clean, and repaint rusted or
10.3.3.1.2. Out-of-Service API 653 Inspection. Use nondestructive techniques to inspect all
metallic surfaces, including the floor.
FREQUENCY: Every 10 years.
10.3.3.2. Floating Roof or Pan.
10.3.3.2.1. Clean and check perimeter tank seals; check centering of roof or pan. The
performance of this task may require a confined space entry.
10.3.3.2.2. For open-top floating-roof tanks, ensure the center primary roof drain system is
water-free, the drip-tight plug is placed in the roof drain opening, and the roof drain valve is
closed. The drain valve is kept in the closed position except after each rain or snowfall when
it will be opened just long enough to drain the roofline.
10.3.3.2.3. The LFM shop foreman is responsible for training FMF personnel on procedures
for draining floating-roofs and interior dike basins. Once trained, FMF retains responsibility
for draining roof drains and interior dike basins.
10.3.3.2.4. At locations where freezing conditions are encountered, the LFM shop will fill
the floating-roof tank drain line with antifreeze or deicing fluid. Periodically test the
