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
