Petzl ASAP Lock

Equipment Specifications:

Petzl ASAP Lock

 
Primary functions

  • Back up device for use within rope access system
  • Back up device for hauling and lowering systems
  • Back up device for rescue
  • Mobile Fall arrest device with flexible safety rope

Primary Features

  • Constant fall protection:
    – arrests falls, slides, and uncontrolled descents
    – works on vertical or angled rope
    – locks on the rope even if grabbed during the fall
  • Integrated locking function
  • At moderate speeds, the locking wheel turns freely in both directions
  • A rapid downward movement causes the locking wheel to stop rotating; the rope is locked by pinching between the wheel and the frame

Standards and certifications

  • EN 12841 Type A: 2006
  • EN 353-2: 2002

Specifications and limitations

  • For use with EN 1891 A Rope 10mm-13mm in a rope access system
  • For use with Petzl Parallel 10.5mm rope or Axis 11mm rope in a fall arrest system
  • Must be used with Petzl Absorbica or Sorber lanyard, properly installed with tool

Proper handling and use

General

  • Attach with Petzl Absorbica or Sorber lanyard to sternal harness D ring
  • Install on rope with arrow towards tensioned side of rope and ensure secure closure of both cams
  • Function check by moving device up the rope then pulling down to ensure it locks down on the rope and check the function of the lock button
  • To unlock the device, it must be pushed upward, keeping the locking wheel
    pressed against the rope, so that it turns counter-clockwise
  • Required clearance height with absorbica, FF1- 1.5m plus rope stretch; FF2- 2.4m plus rope stretch

Special situations

  • On low angles, ASAP may not recognize a slow slide as a fall. Install knots in the ropes to prevent impacting obstacles or falling over an edge
  • In windy conditions, use lock feature and weight or anchor rope below
  • On a taut rope, the ASAP will still function

Belaying when lowering from anchor

  • Use extra carabiner to direct tail rope in line with device
  • To prevent slack from developing, hold the tail rope when lowering and use the lock button to go hands free

Rescue

  • Use absorbica lanyard only
  • More clearance required 5m plus rope stretch
  • Minimize slack in the back up system
  • If practical, both rescuer and victim should each have a device on separate ropes

Pre-use inspection

  • Verify that the absorber is correctly installed on the clevis, and that the latch is properly tightened
  • Verify there are no cracks, nicks, deformation, wear, corrosion (on the frame, wheel, arm, clevis)
  • Verify the condition of the safety catches, and that their return spring works
  • Verify that the arm pivots on the axle, and that the return spring works
  • Verify that the locking wheel is clean and that the teeth are not worn out. Warning: if one or more teeth are missing, do not use the ASAP. If the teeth are dirty, see the paragraph on Cleaning, maintenance
  • Verify that the locking wheel rotates smoothly, through one complete
  • revolution in both directions
  • Inspect absorbica for evidence of deployment, damage, and wear full function test on rope

Misuse and discrepancies

Major Discrepancy (Fail)

  • Loaded backwards and trying to use in that manner
  • Used with incorrect diameter rope
  • Unacceptably low device, pulling a loop in the rope above the device
  • Connected without energy absorber
  • Lanyard other than absorbica for 2 person load

Minor Discrepancy (Discrepancy)

  • Low device beyond what is allowed by manufacturer
  • Lanyard passing under arm
  • Connection to ventral harness D-ring
  • No re-direct when belaying a lower from top anchor
