ANSI/ASSE Z359 - Requirements for Proper Use and Mainte-
nance of Connectors
These are general requirements and information provided by ANSI/
ASSE Z359, the Manufacturer of this equipment may impose more
stringent restrictions on the use of the products they manufacturer,
see the Manufacturer’s instructions.
1 - GENERAL INFORMATION
1.1 -
The user’s organization shall retain the manufacturer’s instruc-
tions and make them readily available to all users. Users shall read
and perfectly understand the information provided by the manufac-
turer before using the device, shall comply with all instructions re-
garding the inspection, maintenance and storage of the equipment
and make sure that the device is in perfect condition and working
properly.
Important
: this information relates to the characteristics,
services, assembly, disassembly, maintenance, conservation, dis-
infection, etc. of the device. Although it does include some sugges-
tions on how to use the device, it cannot be considered a true to
life instruction manual (the same as an operating and maintenance
handbook for a car does not teach how to drive it and does not re-
place a driving school).
Warning: rescue work, tree climbing and
works at height are activities with a high degree of risk, which
may lead to accidents and even death.
The user takes complete
responsibility for the risks deriving from these activities and from
using our devices. This device can be used only by individuals medi-
cally fit. It is essential that the users of this type of equipment receive
proper training and instruction, including detailed procedures for the
safe use of such equipment in their work application. ANSI/ASSE
Z359.2 establishes guidelines and requirements for an employer’s
managed fall protection program, including policy statements, du-
ties and responsibilities, training and evaluations, minimum require-
ments for fall protection procedures, eliminating and controlling fall
hazards, rescue procedures, incident investigations, and evaluating
program effectiveness.
1.2 -
If the user has the slightest doubt concerning the efficiency of
the device, it shall be replaced immediately, particularly after having
used it to arrest a fall.
1.3 -
Minimum resistance of anchoring points, on both natural and
artificial elements, can be at least 12 kN. The assessment of those
made on natural elements (rocks, plants, etc.) is possible only em-
pirically, and can therefore be performed by a competent expert,
while those on artificial elements (metal, concrete, etc.) can be cal-
culated scientifically, and can therefore be performed by qualified
personnel.
1.4 – 414.O00 - 414.T00 OVALONE DNA ANSI
is tested in accor-
dance to ANSI/ASSE Z359.12-2009.
This device is inspected in accordance with the procedures of the
Quality System certified according to the UNI EN ISO 9001.
Warning: laboratory tests, inspections, information and norms
do not always manage to reproduce what actually happens in
practice, and so performance under real usage conditions in a
natural environment may differ, sometimes even considerably.
The best information can be gained by continual practice under
the supervision of skilled, expert, qualified individuals.

have not to affect or interfere with the safe function of each other.
- Improper use, deformation, falls, wear, contact with chemical sub-
stances, chemical contamination, exposure to direct sunlight (UV
degradation), heat sources and flames, exposure to temperatures
below -20°F or higher than +120°F, are some examples of other
causes that may produce a harmful effect, or reduce, limit or end
the life of the device. We strongly suggest using the device person-
ally in order to continuously monitor the degree of protection and
efficiency.
- At low temperatures, the presence of moisture can form ice that,
on textile devices, can reduce flexibility and increases the risk of cutting
and abrasion.

(PPE)
known as
OVALONE DNA
ANSI,
in the versions
Autoblock 414.O00
and
Twistlock 414.T00,
(fig.
1) is a connecting component used to connect two or more pieces of
equipment together in Personal Fall Arrest Systems. This device is cer-
tified according to ANSI/ASSE Z359.12-2009.
Nomenclature of parts (fig. 1): (A) Body made in Carbon Steel, (B) Gate
made in Steel, (C) Automatic gate locking device made in Steel: (C1)
Autoblock, (C2) Twistlock.
Carefully assess the suitability of the attachment/anchoring point cho-
sen in relation to the application for which it is to be used, applicable
governmental regulations and standards on occupational safety. Espe-
cially, always make sure that the connectors attached to the attachment/
anchoring point are free to move and take up a position in the foresee-
able direction in which the load will be applied, with the gates fully closed
at all times.
Only permitted position, providing the greatest strength (fig 2a).
Warning:
- not permitted positions, those can cause lateral and/or sideways
forces and/or twisting and/or direct forces on the gate (fig. 2b).
- connecting using wide elements reduces the connector’s strength
(fig. 3) and may compromise releasing and closing the gate (fig. 4).
Important:
- before using the connector for hanging, calculate the actual loads that
will be applied (fig. 5).
- it is recommended to never exceed ¼ of the load marked on the con-
nector (SWL 1:4),
- make sure the gate locking device works as described in figures 6 and 7,
- do not open the gate when the connector is loaded,
- regularly inspect and monitor the system during use and check locking
and positioning of the connector,
- take the connector’s length into consideration, when using it in a sys-
tem to prevent falling.
