Question 3515 Deck General

You are correct, the answer is B) sandblasted. Prior to magnetic particle inspection, anchor chain should be sandblasted to remove any surface contaminants or buildup that could interfere with the inspection process. Sandblasting helps ensure the magnetic particles can effectively adhere to and highlight any potential defects or cracks in the chain links. The other options are incorrect because: A) soaking the chain would not properly prepare the surface, C) demagnetizing would not be necessary before inspection, and D) degaussing is a process to remove or reduce a magnetic field, which is also not required prior to this type of non-destructive testing.
