A-3.4 Tank Technical Testing
Dry -Film Thickness
Dry -film thickness (DFT) is the thickness of a
coating after it has cured. DFT measurements on
the tank were NOT taken on 08/06/2020. DFT
measurements were recorded using a PosiTest
Model FM Coating Thickness Gage
developed for the non-destructive
measurement of non-magnetic coatings on
ferrous surfaces. The PosiTest® FM Coating
Thickness Gage is a magnetic pull -off
thickness gage. Testing with magnetic gages
is sensitive to surface roughness, curvature,
substrate thickness, and the make-up of the
metal alloy. Typical tolerance is ± 5%.
Advanced Diving Services employs this test
method to allow us to test both interior and
exterior tank surfaces. No surfaces were
tested on this reservoir.
The readings were NOT taken from various spots
of the tank exterior. Six to eight readings were
NOT taken from each quadrant.
DFT readings were as follows:

Paint Samples
Collection of internal and external paint samples
for metal analysis was not conducted by ADS at
JBLM in 2020.
Ultrasonic Testing
Advanced Diving Services Incorporated
employs a Cygnus Instruments Dive, digital
ultrasonic multiple -echo thickness gauge to
provide accurate measurement(s) of metal
thickness.
The gauge was last calibrated by Cygnus on
XXXX. Cygnus Instruments declares accuracy
of 0.1 mm when calibrated in accordance
with Cygnus Instruments
calibration procedures.
The reservoir was not tested floor thickness in
each quadrant. Results are as follows:

The interior ceiling showed minimal corrosion.
Corrosion density was between 0 and 1 on the

interior conducted by certified dive personnel.
Inspection work does not include repairs, except
that, if vent screens, cotter pins or nut pins are
found to be missing, they may be replaced at
once, or reported promptly to the tank/reservoir
owner/agent for replacement. On the day of
inspection ADS found no immediately reportable
repairs.

A-3.4 Tank Technical Testing
Dry -Film Thickness
Dry -film thickness (DFT) is the thickness of a
coating after it has cured. DFT measurements on
the tank were NOT taken on 08/06/2020. DFT
measurements were recorded using a PosiTest
Model FM Coating Thickness Gage
developed for the non-destructive
measurement of non-magnetic coatings on
ferrous surfaces. The PosiTest® FM Coating
Thickness Gage is a magnetic pull -off
thickness gage. Testing with magnetic gages
is sensitive to surface roughness, curvature,
substrate thickness, and the make-up of the
metal alloy. Typical tolerance is ± 5%.
Advanced Diving Services employs this test
method to allow us to test both interior and
exterior tank surfaces. No surfaces were
tested on this reservoir.
The readings were NOT taken from various spots
of the tank exterior. Six to eight readings were
NOT taken from each quadrant.
DFT readings were as follows:

Paint Samples
Collection of internal and external paint samples
for metal analysis was not conducted by ADS at
JBLM in 2020.
Ultrasonic Testing
Advanced Diving Services Incorporated
employs a Cygnus Instruments Dive, digital
ultrasonic multiple -echo thickness gauge to
provide accurate measurement(s) of metal
thickness.
The gauge was last calibrated by Cygnus on
XXXX. Cygnus Instruments declares accuracy
of 0.1 mm when calibrated in accordance
with Cygnus Instruments
calibration procedures.
The reservoir was not tested floor thickness in
each quadrant. Results are as follows:
Measurements: Redwood Tank

Corrosion Evaluation
The tank interior showed minimal corrosion.
Corrosion density was between 0 and 1 on the
ASTM standard rating chart.
The interior ceiling showed minimal corrosion.
Corrosion density was between 0 and 1 on the
ASTM standard rating chart.
The interior floor showed minimal corrosion.
Corrosion density was between 0 and 1 on the
ASTM standard rating chart.
The interior corrosion was not pervasive, and the
areas effected varied by size. The depth of
corrosion was not measured.

The new OSHA General Industry fall protection regulations that went into effect in 2017 are prompting a slew of questions on fixed Ladders- If
you are wondering when a fixed ladder requires fall protection. which forms of ladder fall pnotecti on are OSHA compliant or if ladder cages still
comply with OSHA's revised ruling, we have just the post for you-..-.
If you carefully examine she new ruling, you'll note that OSHA 1910.28&W) requires General Industry employers to provide fall protecton on Fixed
ladders more than 24' above a lower level. This new requirement is important fir a number of reasons. For starters- prior to the new ruling, the
only real guidance on fixed ladders came from the Con struclion Standards- OSHA more (1926.19S3(aH 18) required she use of cages, wells, (adder
safety devices, or sell -relratting Idelines for fixed ladders df 24 feet or more. OSHA's new ruling was designed, in part, to create more uniformity
between the General Industry and Construction standards- That said, the revised ruling also breaks new ground by creating a Framework to phase
out the use of ladder weds and cages.
From a test practices standpoint, we have never been fans of (adder rages because they don't arrest falls. You can stake your head during a fall,
lose consciousness, and create an extremely difficult rescue scenario for first responders- There are also cases of gruesome entanglements where
falling workers tear off body parts during a rapid, uncontnol led descent
The rev sed ruling establishes a phase out of ladder wells and cages over the next 20 years per OSHA 1910-128(b](9)(r)- Here are the
implementation details:
• For caged, fixed [adders erected before November 19, 2018, employers have up to 20years to install ladder safety it personal fall arrest
systems (191028(bH9)i?Y(A)7
• For new fixed ladders erected on or after November 19,2018, the employer must equip the ladder with a ladder safety or personal fall arrest
system {1910-28(b)(9)[iH8)j
• For ladder repairs and replacements, when an employer replaces any portion of a fixed ladder, the replacement must be equipped with a
ladder safety or persoral fait arrest system t1910 26(b)(9Xi){C)J
• After November 1& 2036 all fixed ladders must be equipped wrth a ladder safety or personal Fall arrest system f 1910.28(b)(9)UY(0)l
Important Note: The revised ruling doesn't require removal of ladder rages and welts prior to the final deadline (as fang as their
presence doesn't in ferfere with the use of a ladder sofery system or personal fill arrest sys fem), but stipulates after the phase -our period,
alternafive forms of ladder fall protection are required to ensure compliance,
We dedicated this post to a discussion of how the new OSHA regulations effect fixed ladder fall protection options, but the revised Walk inu-
Working Surfares Ruling is over SW pages in length and covers a wide range of additional topics relating to ladders. 11 you are kokintg for a
