Question 1

During a pre-use inspection, a worker notices a navigation light bracket on the mast has a visibly corroded mounting bolt, but the bracket isn't due for scheduled inspection for another two months.

What should the worker do?

Accepted Answer

Report the observed defect immediately so the bracket can be assessed and secured/repaired ahead of schedule, regardless of the planned inspection date Scheduled inspection intervals are a minimum baseline, not a reason to ignore an observed defect found in between. DROPS culture relies on anyone noticing a hazard reporting it immediately.

Question 2

Per DROPS' official Reliable Securing terminology, what is "Primary Fixing"?

Accepted Answer

The method by which an item is installed, mounted and secured to prevent it falling - e.g. bolted connections, screws, pins, buckles, clips, welds Primary Fixing is the main installation method keeping an item in place under normal conditions; DROPS defines two further layers (Secondary Retention, Safety Securing) that exist specifically to cover the case where the Primary Fixing fails.

Question 3

DROPS' Reliable Securing guidance defines THREE distinct layers of securing, not two. What are they, in order?

Accepted Answer

Primary Fixing, then Secondary Retention, then Safety Securing Secondary Retention (e.g. locking washers, locking wire, split pins) prevents loss of clamping force or displacement of the Primary Fixing's own components. Safety Securing (e.g. rated nets, baskets, wires, slings) is an additional, independent restraint where Secondary Retention isn't feasible.
