and precise), 3) Detailed (sufficient information)
◉ Should an inspector accept gifts from contractors? Answer: No,

ethics.
,◉ What types of reports might an inspector prepare? Answer:
Daily/weekly summary reports, material usage reports, manpower
and equipment logs, conformance and non-conformance reports.
◉ Is the inspector responsible for enforcing safety regulations?
Answer: No, the inspector should be aware of safety issues and

observes and reports on conformance to specifications.
◉ What document must inspectors sign acknowledging their
professional responsibilities? Answer: The NACE Attestation.
◉ What is corrosion? Answer: The deterioration of a substance
(usually metal) or its properties from a reaction with its
environment.
◉ What are the four elements required for a corrosion cell? Answer:
1) Anode, 2) Cathode, 3) Metallic Pathway, 4) Electrolyte.
◉ What happens at the anode in a corrosion cell? Answer: The metal
dissolves into the electrolyte (oxidation/metal loss occurs here).
, ◉ What happens at the cathode in a corrosion cell? Answer:
Reduction reactions occur (the cathode is protected from corrosion).
◉ Name three metals that can be used as galvanic anodes for carbon
steel. Answer: Aluminum, Magnesium, and Zinc.
◉ What is the galvanic series? Answer: A list of metals arranged by
their electrochemical activity from most active (anodic) to most
noble (cathodic) in a given environment.
◉ List metals from most active to most noble (at least 5). Answer:
Magnesium → Zinc → Aluminum → Carbon Steel → Stainless Steel →
Copper → Silver → Gold → Platinum.
◉ What is general (uniform) corrosion? Answer: Corrosion that
occurs relatively uniformly across the entire exposed surface.
◉ What is pitting corrosion? Answer: Localized corrosion that
creates small holes or pits in the metal surface.
◉ What is galvanic corrosion? Answer: Corrosion that occurs when
