Note: Hardware in this condition is recommended for removal from service.
*Dee rings are not shown above but shall follow the same Rust on Harness Hardware criteria as shown above*
Please contact your Buckingham Customer Service Representative at 800-937-2825 should you have any questions as to condition of the
hardware or your product.
Storage
Storage areas should be clean, dry and free of exposure to corrosive elements, fumes, etc.
To aid in protecting the hardware from rusting, it is recommended that the hardware be treated with WD-40 Multi-Use Product or Hilco Lube
lubricant cleaner at regular intervals.
Note: Also reference the used Inspection, Maintenance and Storage of Equipment Criteria of Annex A.
Properties of Full Body Harness (FBH) Materials
Material
Effect of Heat
Effect of Acids & Alkalis
Effect of Bleaches &
Solvents
Resistance to Mildew,
Aging, Sunlight,
Abrasion
Polyester
Sticks at 440 to 445°
F.
Melts at 482° F.
Good resistance to most mineral acids.
Dissolves with partial decomposition in
concentrated solution of sulfuric acids.
Good resistance to weak alkalis.
Moderate resistance to strong alkalis at
room temperature. Disintegrates in
strong alkalis at boil.
Excellent resistance to
bleaches & other oxidizing
agents. Generally insoluble
except in some phenolic
compounds.
Not weakened by
mildew. Excellent
resistance to aging &
abrasion. Prolonged
exposure to sunlight
causes some strength
loss.
Nylon 6
Melts at 419 to 430° F.
Slight discoloration at
300° F when held for 5
hr. Decomposes at
600 to 730° F.
Strong oxidizing agents & mineral acids
cause degradation. Others cause loss
in tenacity & elongation. Resists weak
acids. Soluble in formic & sulfuric acids.
Hydrolyzed by strong acids at elevated
temperatures. Substantially inert in
alkalis.
Can be bleached in most
bleaching solutions.
Generally insoluble in
organic solvents. Soluble
in some phenolic
compounds.
Excellent resistance to
mildew, aging &
abrasion. Prolonged
exposure to sunlight
causes some
degradation.
Nylon 6,6
Sticks at 445° F. Melts
at 480° to 500° F.
Yellows slightly at
300° F when held for 5
hr.
Unaffected by most mineral acids,
except hot mineral acids. Dissolves with
partial decomposition in concentrated
solution of hydrochloric, sulfuric & nitric
acids. Soluble in formic acid.
Substantially inert in alkalis.
Can be bleached in most
bleaching solutions.
Generally insoluble in
organic solvents. Soluble
in some phenolic
compounds.
Excellent resistance to
mildew, aging &
abrasion. Prolonged
exposure to sunlight
causes some
deterioration.
Kevlar
Difficult to ignite. Does
not propagate flame.
Does not melt.
Decomposes at about
900° F.
Good resistance to dilute acids and
bases. Degraded by strong mineral
acids and, to lesser extent, by strong
mineral bases. Best chemical
resistance from Kevlar 149.
Should not be bleached.
Excellent solvent
resistance.
Excellent resistance to
mildew & aging.
Prolonged exposure to
sunlight causes
deterioration, but fibers
self-screening. Good
abrasion resistance.
Nomex
Does not melt.
Decomposes at 700°
F.
Unaffected by most acids, except some
strength loss after long exposure to
hydrochloric, nitric & sulfuric. Generally
good resistance to alkalis.
Unaffected by most
bleaches & solvents except
for slight strength loss from
exposure to sodium
chlorite.
Excellent resistance to
mildew & aging.
Prolonged exposure to
sunlight causes some
strength loss. Good
abrasion resistance.
