Weld Metal Control
• Welding filler metal
– All filler metal must be controlled at all times.
• Filler metal shall be within arms reach and in the line
of sight of the welder.
• This includes, but is not limited to, breaks, lunch, and
the end of each shift.
– Consumed electrodes must be placed in a labeled
container.
• Placing consumed electrodes on the ground or
undesignated areas is un-acceptable.
– Welding filler metal must be protected from moisture.
– Welding electrodes must be stored in a rod oven as
described in AWS D1.1 structural welding code, or
QAI312.1
• Flux coated weld rods (i.e., 7018) must be stored in
hot boxes after the container has been opened.
• Wet flux coated weld rods have to be reconditioned
or baked in accordance with manufacturer’s
instructions.

Don’t lose control of welding filler metal
Welding & Brazing Documentation
• Any contractor performing welding or brazing operations at NNS is
required to maintain accessible records of all work on piping, anchors,
supports, structures, etc.
• These documents must identify:
– Welder Name
– Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR)
• Base and Filler Metals called out in PQR must match actual materials in the field.
• If base metal is unknown, lab analysis shall then be performed.
• Prior to any production welding, the contractor is required to provide a
statement that all welders have demonstrated ability to produce sound
welds in accordance with qualification requirements
• Welder’s log with date and WPS used is acceptable.
For more information on welding and brazing requirements please reference the
Facilities Master Specification Section 15059 Welding and Brazing.

Foreign Material Exclusion Devices (FMEDs)
• Why do we care about cleanliness?
– Debris or foreign material left in piping systems can create risk to personnel safety,
ship operations, cost increase and schedule delays.
– Loss of cleanliness results in loss of customer confidence.
• Flushing is for verification of cleanliness, not for cleaning.
7
FMEDs
• FMEDs are available at the O46 conex
box located on the Leyte Boiler platform
(North of B4613).
• Your coordinator must send a charge
number to Steven Thomas
[email protected]
or 757-534-4093
• All piping shall come from
the supplier with FMEDs.
• If supplier did not provide
FMEDs then the contractor
must place FMEDs on the
material before it comes
into the yard.
8
POC for contractor rented equipment
• Equipment that is delivered to NNS Ship Yard must have point of
contact posted.
– Company Name
– Name of POC
– POC phone number or company phone number
9
Use of Engine-Powered Equipment at NNS
• EPA regulations establish air emission limitations for stationary, land-based (i.e., permanently
“bolted down” at a fixed location) reciprocating internal combustion engine-powered equipment.
• The regulations apply to portable engine-powered equipment if the equipment remains at, or will
remain at, “a location” for more than 12 consecutive months.
• This includes any portable engine-powered equipment, located and operated at the shipyard,
and owned by NNS, leased by NNS, or supplied by a contractor/subcontractor.
– For example, trailer or skid-mounted generators, compressors, pumps and vacuum loaders.
• Equipment information must be submitted to Environmental Engineering so that the appropriate
air permits can be obtained by NNS.
– Permits must be obtained prior to bringing any new emission source to NNS.
• AIR EMISSION REQUIREMENTS
– Engine (any size, manufactured any year) used or change in location in less than 12 months ARE NOT REGULATED.
– Engines under 500Hp (diesel) or 250 Hp (Gasoline, LPG) and built after 2007 in one location more than 12 months.
• Can meet regulations by completing paperwork.
– Engines over 500Hp (diesel) or 250 Hp (Gasoline, LPG) or built before 2007 in one location more than 12 months.
• Submit emission testing protocol for engine
• Connect engine to load bank equipment.
• Perform annual emissions testing.
• Submit results to EPA.
10
Use of Engine-Powered Equipment at NNS
• The regulation does not apply to:
– Engines that are to be permanently installed in vessels, such as emergency
generators or pumps.
– Engines in self-propelled equipment, such as forklifts, mobile cranes, material
transporters, mules, street sweepers, passenger vehicles, trucks, patrol boats and
tug boats.
– Engines in equipment that is intended to be propelled by the operator while in use,
such as mowers, chain saws, blowers and string trimmers.
– Engines that power equipment mounted on other self-propelled equipment, such as
salt spreaders and sprayers.
11

12
Roadway Traffic During Construction
• Temporary Traffic Control Plans
– Health & Safety Approval
– Pedestrian Walkways
– Signs
• One Way
• Stop
• Road Closed
• Detour
– Barricades
– PPE
• As indicated in company’s safety plan
13
Torch Safety
• Burning/cutting
– Always perform a "Torch Safety Check" (60 second drop test) on all torch equipment
at the start of each shift. This sixty second pressure drop test must be performed to
verify that there are no leaks in the oxygen and fuel gas hoses, torch valves and
equipment connections. This test must be conducted in an open area.
• The blank tip or plug must not be in the torch during the Torch Safety Check.
• Adjust the operating pressures at the fuel gas and oxygen regulators by turning
the adjusting screws clockwise.
• The pressure at the regulators should be set somewhat higher than the required
tip pressures.
• Close the manifold or cylinder supply valves and watch the gauges for sixty (60)
seconds.
• Any drop in pressure indicates a leak.
• If no drop in pressure, then you may proceed.
14
Torch Safety
• Cutting/Burning in Confined Spaces
– Never place an oxygen or fuel gas cylinder into a confined space.
– Before going to work in a confined space, be sure that it is well ventilated by blowers
provided for that purpose.
– Any hose located within the confined space shall be free of splices, worn places, cuts, or
other defects which might be a source of leakage.
– A qualified Fire Watch, who has been fully instructed in emergency procedures, shall be
stationed at the entrance to the confined space. The fire watch shall have a hose clamp
loosely placed around the torch lines to be able to rapidly shut off the gases in an
emergency. The fire watch shall not leave his/her station while the operator or his/her
equipment remain inside the confined space. The Fire Watch shall be so positioned to be
able to observe or converse with torch operator.
– The equipment shall be removed from the confined space when the operator leaves the
job. Before work resumes, the torch shall be retested before returning it to the confined
space.
– When the hoses must pass through more than one manhole to reach the job site, the
situation is considered extremely hazardous and the work shall not be undertaken except
under the direction of a Supervisor.
– Do not blow out lines, drain hoses or disconnect or reconnect torches within a confined
space. Fuel gas tends to collect in pockets and can form an explosive mixture.
– Do not use hoses over 250 feet long when working with propane and oxygen or acetylene.
15
Torch Safety
• Contractors and Torch Operator Must
– Ensure that torch lines with mechanical connections and “Y’s” are not allowed
below decks.
– Inspect all equipment (hoses, torch tips, manifolds, regulators, cylinders etc.) prior
to use for any damage or signs of wear.
– Ensure fire watches have the appropriate extinguisher.
– Contractors shall ensure that personnel designated as fire watch be trained.
