Figure 5-132.  The length and width of the S-fold is determined by  the width of the container and the distance between the main/reserve  vertical partition and the bottom flap grommet. Figure 5-135.  Inside the Reserve Speed Bag the buffer tabs form a  clear channel for the bottom closing loop. Figure 5-133.  Make a second S-fold with the upper part of the  canopy on top of the lower part. Figure 5-134.  Prepare the Reserve Deployment Speed Bag by using  a hemostat to pinch the inner buffer tabs together as shown. Finally, riggers are tasked with noting their name and  certificate number on the data card. In many cases, this  information is illegible. Riggers who take pride and  responsibility in their profession and the work they do have  no hesitation in letting the public know who did the work.  Accordingly, many riggers have a permanent ink stamp with  their name, certificate number, and seal symbol that they use  to stamp the card and then countersign it. This is the mark  of a truly professional rigger. While the seal symbol is not  required on the data card, it allows anyone to check the  signature against the seal on the parachute. It is the responsibility of the attending rigger to ensure  that the components of the approved parachute system are  compatible in terms of shock load capability. This may be  as simple as reading and comparing the TSO/Data Label  that is permanently attached to the reserve canopy and the  harness. This information may also be found in the respective  done that requires documentation, it may be necessary for  the rigger to fill out a duplicate card with the appropriate  notations as to the work done on the harness. Riggers should  make sure that they note that this card is a copy of the original. Chapter Summary 5-42
