Who is an individual assigned to the QA department who is responsible for determining if a fuel system is safe from hazards?

• A. Quality Assurance Inspector
• B. Safety Officer
• C. QA Manager
• D. Entry Authority (EA)

Answer: (D)

For entry into a fuel system, someone must have control over the authorization to enter and the verification that all hazards have been mitigated. That person is the Entry Authority. They review the required safety checks, ensure proper isolation of energy sources, depressurization or draining of fuel, ventilation and gas monitoring, and the presence of a fire watch and appropriate PPE. They issue the entry permit and can halt work if conditions aren’t safe, tying together the precautions needed to prevent ignition, exposure to vapors, or other hazards.

QA inspectors and QA managers focus on quality assurance and procedural compliance, not the explicit authorization to enter a hazardous area. A Safety Officer oversees overall safety programs but does not typically grant entry to a live, hazardous system. The role dedicated to determining when a fuel system is safe for entry is the Entry Authority, which is why that option is the best answer.
