ASSEMBLY CONTINUED
INSPECTION AND REPLACEMENT
RECOMMENDATIONS
Inspect the hard hat, including the suspension and
shell, before and after each use. Replace the hard hat
immediately if noticing any signs of wear, damage,
abuse or degradation. This may be a sign that
protection is reduced.
• If the hard hat has sustained an impact, dispose of it
immediately, even if damage is not visible.
• Inspect hard hat shell for any signs of breakage,
gouges, cracks, dents, chalky appearance,
discoloration or loss of color, craze pattern or any
other signs of wear. Replace shell immediately if
any signs of wear are present. Certain hard hat
shells include a 3M Uvicator™ Sensor designed to
change color when exposed to certain amounts of
UV light. (See Figure 9) Replace hard hat shell when
sensor turns white or immediately if any of the signs
of wear described above are present. Even with no
visible signs of wear and if the Uvicator sensor has
not changed to white, 3M recommends the shell be
replaced at least every two to five years depending
on work environment.
• Inspect head suspension plastic parts for breaks,
cracks or loss of flexibility. Inspect straps for fraying
or stitching that is loose or damaged. Replace
suspension immediately if these or other signs of
wear are present. Even with no visible signs of wear,
3M recommends replacing the hard hat suspension
at least every 12 months.
• Always use 3M replacement parts. This product
works as a system and use of unauthorized
suspensions will reduce the protection user receives
from this hard hat.
• Never alter, puncture, modify or engrave the shell
or the suspension. Any such change or structural
modification will reduce the protection user receives
from this hard hat.
MAINTENANCE
• Clean the hard hat and suspension with mild soap
and water. Rinse and wipe dry.
• Do not use paints, solvents, chemicals, adhesives,
gasoline or like substances on the hard hat. Doing
so can lessen the protection from impact and
penetration.
• Exposure to direct sunlight and heat over time can
lessen the ability of the hard hat to withstand impact
and penetration. When possible, store hard hat out
of direct sunlight, including the dashboard or rear
window shelf of a vehicle, and extreme heat over
120°F.
