Where should a diver position themselves relative to a heavy object being raised with a lift bag?
Answer: To the side and slightly below the object
Positioning to the side and slightly below keeps the diver clear of the object's ascent path if the lift bag rises uncontrollably.
What is the PADI-recommended primary method for inflating an open-bottom lift bag underwater?
Answer: Direct air from the second stage regulator into the bag's open bottom
PADI teaches inflating open-bottom lift bags by directing air from the second stage regulator (by purging or exhaling) into the bag's open bottom.
What is the purpose of a 'spider' or 'octopus' rigging system in search and recovery?
Answer: Multiple attachment lines from one lift bag to balance and level a large object
A spider rig uses multiple lines connecting a single lift bag to several attachment points on an object, distributing weight evenly to keep it level during ascent.
When rigging a heavy, irregularly shaped object for recovery, what is the PRIMARY concern?
Answer: Ensuring the object is stable and securely attached to prevent slipping
Heavy, irregular objects can shift or slip if improperly rigged, creating serious hazards for nearby divers and risking loss of the object.
How should lift bag capacity be matched to the object being recovered?
Answer: The lift bag capacity should closely match the object's submerged weight
Matching lift bag capacity to the object's submerged weight gives divers control over the lift and prevents dangerous uncontrolled rapid ascents.
What should a diver do if a lift bag begins ascending faster than anticipated during a recovery operation?
Answer: Release the line immediately and clear away from the object's path
Holding onto a rapidly ascending lift bag could carry the diver to the surface dangerously fast; releasing the line and clearing the area protects the diver.
In PADI Search and Recovery, what is the purpose of leaving a 'tag line' at a found object's location?
Answer: To guide divers back to the exact object location on subsequent dives
A tag line is left in place at the found object so the team can follow it back to the precise site after surfacing to prepare recovery equipment.
