D. FREE FALL: Personal fall arrest systems must be rigged in such a way as to limit the free fall to a maximum
distance of six (6) feet (Ref. ANSI Z359.1-1992).
E. FALL CLEARANCE: Make certain that enough clearance exists in your fall path to prevent striking an object.
The amount of clearance needed is dependent on the subsystem in use and the anchor location.
F. CORROSION/EXPOSURE: Usenearseawater or in other corrosiveenvironmentsmayrequiremore frequent
inspections or servicing (replacement) to assure that corrosion or other exposure damage is not affecting
performanceofthe product.
G. CHEMICAL HAZARDS: Solutions containing acids, alkali, or other caustic chemicals, especially at elevated
temperatures, may cause damage to this equipment.Consult PROTECTA if doubts exist concerning installation
ofequipmentwhere chemical hazards arepresent.
H. ELECTRICAL HAZARDS: Do not install the AJ720A where it or the user may come into contact with electrical
powerlines.
I. TRAINING:This equipment isintendedto be installedandused bypersonswho have beenproperly trainedin
its correct application and use.
2.0 SYSTEM REQUIREMENTS
2.1 ANCHORAGE STRENGTH: Forfallarrestapplications,theanchoragepointatwhich the AJ720A ConcreteAnchor
is installed must meet minimum strength requirements. Strength requirements for fall arrest devices and systems
areoutlinedbelow.
2.2 FALL ARREST REQUIREMENTS: Anchorage devices installed for fall arrest applications must be attached to a
structural member capable of sustaining static loads in the direction(s) permitted by the PFAS when in use of at
least:(A) 3,600 lbs.(16 kN) where certification exists (reference ANSI Z359.1-1992 for certification definition), or
(B) 5,000 lbs.(22.2 kN) in the absence of certification.When more than one anchor is installed to a structure, the
strengths given in (A) or (B) above must be met at each anchor installation point independently.EXAMPLE:If two
anchors are installed on to a roof structure, each anchor must be independently capable of supporting 5,000 lbs.(or
3,600 lbs.with certification).

3.1 BEFORE INSTALLATION of this equipment, carefully inspect it to ensure that it is in serviceable condition.Check
for missing or damaged parts.D-ring, plate, and bolts should be free from corrosion.Nuts should be tightened to
required torque (see section 3.0). Refer to section 5.0 for more details. Do not use if inspection reveals an unsafe
condition.
3.2 PLAN your fall arrest or restraint system before starting your work.Take into consideration factors affecting your
safety at any time during use.The following list gives some important points you must consider when planning your
system.
3.3 ANCHORAGE: Selectananchoragepointthat is rigidandcapableofsupporting the required loadsandin the
properlocation.
3.4 FREE FALL: Personal fall arrest systems must be rigged to limit any free fall to a maximum of six (6) feet (OSHA
and ANSI Z359.1-1992).Restraint systems must be rigged so that NO vertical free fall is possible.Avoid working
above your anchorage level as increased free fall distance will result.
