Click to view effect of Safety Grate on hatch
clear openings.
Description:
The
Hinged Hatch Safety Grate
smoothly rotates 90 degrees to its open
position and locks in place by a hold-open
rod.
The aluminum
grate has an OSHA safety orange finish.
Hardware
components are made of 316 stainless steel
to withstand corrosive wastewater
environments.
Features: The
Hinged Hatch Safety
Grate provides continuous safety
assurance in both its closed and open
positions.
When closed, the grate system allows
people to move freely around the hatch
opening without fear of falling into the
opening.
Also, it allows visibility for
inspections and accessibility for limited
maintenance and float adjustments below the
grate.
When open, it acts as an additional
barrier to the access door opening.
Since the hatch cover cannot be shut
without first closing the
Hinged Hatch Safety
Grate, this system insures that
the grate is in position when the next
person opens the hatch cover.
Since the grate does not provide load
reinforcing for the cover, a damaged or
missing grate will not jeopardize the
function of the cover in carrying the
specified load capacity of the hatch.
Retrofit: The
Hinged Hatch Safety
Grate can be retrofitted into
existing openings.
It can be made to fit the custom
dimensions of most floor access hatches.
Specification:
The access opening shall have a permanently
installed fall through prevention grate
system that provides continuous safety
assurance in both its closed and open
positions. When closed, the grate allows
visibility for inspections and performance
of limited maintenance below it.
When open, the
grate acts as an additional barrier to the
access door opening.
The system shall
be a
Hinged Hatch Safety Grate
as manufactured by
U.S.F. Fabrication, Inc., Hialeah, FL 1-800-258-6873 or approved equal.
The fall through
prevention system shall consist of a grate
made of 6061-T6 aluminum and be designed to
withstand a minimum pedestrian load of 300
lbs. per square foot. The grate shall
operate independent of the cover’s
reinforcing so that the cover will continue
to meet specified load and deflection
requirements, even if the grate is damage or
removed.
The grate
openings shall be 4” x 6” to allow both
visual inspection and limited accessibility
for maintenance purposes when the grate is
closed.
The grate will
pivot on an aluminum hinge device with 316
SS hardware that permits it to rotate upward
90 degrees and automatically lock in place.
An aluminum pull rod will be attached to the
grate so the operator is positioned with the
grate between him and the hatch’s opening
whenever he pulls on it to raise the grate.
A 316 SS rod
will automatically engage to secure the
grate in its open position, and can be
lifted upward to permit the grate to close.
The hatch cover
will not be able to shut until the grate is
closed--thereby insuring the grate is in
position when the next operator opens the
hatch cover.
The grate shall
have an OSHA safety yellow finish to
increase visual awareness of the safety
hazard.
Installation of the fall
through prevention system shall be in
accordance with the instructions provided by
the manufacturer.
The complete grate assembly shall be
warranted against defects in material and
workmanship for a period of 10 years from
the date of purchase.
