Precautions should be taken in the design and installation of a PFAS in order to avoid hazards such as thermal, chemical, or
electrical hazards. Avoid moving machinery, sharp and/or abrasive edges, and any other hazard that could damage or degrade
components of the PFAS.
Safewaze D-ring Extrenders are offered in a variety of configurations to suit a multitude of work environments. The unique
features of a specific extender may not be suited for all applications. The following are some restrictions that should be
considered prior to use of your Safewaze D-ring Extender:
Extended Free Falls:
All Safewaze D-ring Extenders are designed and rated for 6’ (1.83 m) and 12’ (3.66 m) FF
applications. For 12’ FF applications, the user must use a Personal Energy Absorber (PEA) rated for for this level of
free fall.
Harsh Chemical Environments:
Work operations in a caustic or acidic chemical hazard environment may cause
damage to your Safewaze D-ring Extender. Damage to the extender due to chemical exposure can, in some instances,
be difficult to detect. In any environment, the extender must be inspected prior to each use, however, a harsh
chemical environment can necessitate more frequent inspections. Care should be taken to inspect the extender before,
during, and after each use. A harsh chemical environment may also cause a need for more frequent replacement of the
extender.
Welding, Arc Flash, High Heat Environments:
If work operations are conducted in an environment where the D-ring
Extender may be exposed to extremely high temperatures, the user should choose an extender specifically designed for
these environments. Specific extenders are available for welding, fire resistance, and ARC Flash environments.
Heavyweight:
Although ANSI Z359.11 specifies a weight capacity range of 130 to 310 lbs. (59 to 140 kg), most
Safewaze D-ring Extenders have a maximum weight capacity of up to 420 lbs. (191 kg). If the user has a weight that
exceeds the ANSI max weight of 310 lbs. (140 kg), it should be ensured that other components of the PFAS are rated
for a heavyweight user.
