Question 1413Deck General70% to pass
What is acceptable flame screening?
AI Explanation
The correct answer is D) A fitted stainless steel screen of 30 x 30 mesh.
This is the correct answer because the US Coast Guard regulations specify that the flame screening for engine and fuel tank ventilation must be a stainless steel screen of at least 30 x 30 mesh. This tight mesh size helps prevent sparks or flames from passing through the screen and potentially igniting flammable vapors.
The other options are incorrect because they do not meet the regulatory requirements for the mesh size and material (brass instead of stainless steel). A single screen is also required, rather than two screens spaced apart.
