Minimum Required Fall Clearance:
The Minimum Required Fall Clearance distances indicated in Table 7 are based upon Ambient, Wet, Hot, and Cold testing results for each unit in the Latitude Pro
Arc Flash SRL-P series. Fall Clearances indicated in Table 7 are calculated using the greatest Actual Arrest Distance out of the four tests performed. Table 6
indicates the specific arrest distance in prescribed condition testing with 0’ offset.
EXAMPLE:
The Latitude Pro Arc Flash SRL-Ps have Actual Arrest Distances of 22”, 21”, 22”, and 23” during Ambient, Wet, Hot, and Cold testing respectively.
By using the greatest distance (Cold=23”) out of the four tests performed and inserting that value in Row B of the Chart in Figure 2, a Total Fall Clearance
of 5’ 11” is required.

Fall Clearance:
There must be sufficient clearance below the anchorage connector to arrest a fall before the user strikes the ground or an obstruction.
Figure 2 illustrates a typical Fall Clearance calculation based on the ANSI Z359.14-2021 prescribed Maximum Allowed Free Fall of 24 in. and Maximum Allowed
Arrest Distance of 42 in. Fall Clearance calculations may vary dependent upon the SRL being used. It is essential that the correct Arrest Distance is used to
determine Minimum Required Fall Clearance.
Personal Fall Arrest:
Safewaze Class 1 SRLs can be used as part of a complete Personal Fall Arrest System (PFAS) for a maximum of one user. Only one user
may be connected to an SRL. Avoid sharp and/or abrasive edges. If contact with an abrasive surface is unavoidable, proper edge protection must be used. The
structure utilized for attachment must be capable of withstanding a load of 5,000 lbs. in all directions permitted by the system. The maximum allowable free fall
is 2 ft.
10.0 ACTUAL ARREST DISTANCE / MINIMUM REQUIRED FALL CLEARANCE
Safewaze SRLs are tested in accordance with ANSI Z359.14-2021 conditioning test protocols. Table 6 reflects the actual performance of each unit in the
Latitude Pro Arc Flash SRL-P series when subjected to Ambient, Wet, Hot, and Cold testing. The Fall Clearance specifications in Table 8 of this manual reflect the
ANSI Z359.14-2021 Maximum Arrest Distance allowance of 42”. Actual Arrest Distances for each unit in the Latitude Pro Arc Flash SRL-P series are indicated
below. These Actual Arrest Distances are typically lower than the 42” maximum as specified per ANSI. In certain instances this may allow for a Qualified Person
to adjust the Minimum Required Fall Clearances indicated in Table 8.
