Question 64Safety & Environmental - 1st Asst/Chief70% to pass
A fuel tank is considered to be gas free when the tank is _______________.
AI Explanation
The correct answer is B) free of all dangerous concentrations of flammable or toxic gases.
A fuel tank is considered to be "gas free" when it is free of all dangerous concentrations of flammable or toxic gases. This means the tank must be tested and verified to have safe, non-hazardous levels of any potentially dangerous gases present. Simply inerting the tank with carbon dioxide (option A) or just ventilating it (options C and D) does not necessarily ensure the tank is completely free of hazardous gas concentrations.
The other options are incorrect because they do not fully meet the regulatory requirement for a tank to be considered "gas free" - which is the complete absence of dangerous gas levels, not just partial measures like ventilation or inerting.
