Overview
All protective clothing should be routinely inspected to insure
continued serviceability. This inspection should take place after
each cleaning, and following any application where the clothing
may have been damaged or contaminated. Damaged clothing should be
immediately removed from service until the decision to repair or
retire has been made by the safety officer or his designee. All
clothing should be cleaned prior to inspection. The following represent
minimum criteria for inspection and should be considered basic rather
then all inclusive.
Char and Heat Damage
All 3 layers should
be examined for charred, burned, or discolored areas that may result
in loss of tensile strength and material degradation. To check for
weakening of fabric, aggressively flex the material and attempt
to push a finger or thumb through the fabric.
Fabric or Material Damage
Clothing
that has become torn, ripped, cut, abraded or otherwise damaged
by wear should be repaired. All Moisture Barrier material, including
sleeve well assemblies, should be checked for peeling or cracking,
which are signs of wear and require replacement.
Thread or Seam Damage
All seams in each
separate layer of the garment shall be inspected for thread or seam
damage and restitched as necessary.
Discoloration
Discoloration to any of
the 3 layers of the protective clothing should be evaluated. Check
all discolored or faded areas for tensile strength by aggressively
flexing the material and attempting to push a finger or thumb through
the fabric. Any loss of strength or weakening of the materials to
the degree where the material can be torn with manual pressure is
a sign of deterioration and the garment should be removed from service
for repair or retirement. Discoloration of the Moisture Barrier
layer may indicate abrasion or other damage that would render the
fabric incapable of preventing water entry.
Moisture Barriers
There is a simple field
test you can perform to check any Moisture Barrier: Place your Liner
on a flat surface (or over a bucket) with the dry Thermal Liner
facing down and dry Moisture Barrier facing up. Pour about 1/2 cup
of water on the Moisture Barrier and wait a few minutes. If the
water passes through the Moisture Barrier and wets the Thermal Liner,
your Liner should be removed from service and repaired or replaced.
Perform this simple test in high abrasion areas like the broadest
part of the shoulders, at the knee, or the seat of the pants), or
where you have detected other potential damage to the Shell or Thermal
Liner. It is difficult to determine with any certainty whether your
Moisture Barrier leaks by looking at either the film or the fabric
it’s laminated to.
Knit Distortion
All knit areas of the
garments shall be examined for loss of strength, loss of shape,
or loss of elasticity.
Reflective Trim
Trim that is loose but
still reflective may be restitched, while trim that has become burned
or otherwise damaged must be replaced. Note that the trim may appear
to be undamaged to the human eye when it has actually lost much
of the ability to reflect. To check for continued reflectivity,
perform a simple “flashlight” test. Standing a minimum
of 40 feet from the trim sample to be examined, hold a flashlight
at eye level and aim the light beam at the sample to be evaluated.
Compare the brightness of the reflected light coming back to a sample
of “new” or unused trim. If the reflected light is substantially
less than that seen on the new trim, the trim needs to be replaced.
Hardware
Check all hardware, including
snaps and dee rings, pocket snaps, zippers, and take-up buckles
to insure functionality. Velcro® should be inspected to insure
that contamination has not affected functionality and that stitching
remains secure.
Retirement
In general, once a garment
has reached the point where repairs will cost more than 50% of the
price of a new garment, it should be retired. When considering retirement,
the authority having jurisdiction should take into account things
like the amount of ground-in soil contained in the garment, any
stains or clinging debris of unknown origin, and overall condition
of each individual layer. If the fibers of the various layers are
beginning to show wear in the form of abrasion, especially in high
stress areas such as the Outer Shell inseam of Trousers, there is
no way to restore them to like new condition, nor any way in which
to prevent further breakdown. Repair to garments with these conditions
are usually not cost effective.
In Conclusion
Eeach and every one of the items contained in this
bulletin should be considered when trying to decide if a garment
has reached its useful life span. The bottom line, regardless of
when the clothing was produced, is that the safety officer or authority
having jurisdiction must routinely inspect protective clothing in
order to assure that it is clean, maintained, and still safe. Just
knowing the age of the garments cannot do that and for safety sake,
any judgment call should be made erring on the side of caution.
