Question 254Safety & Environmental - 1st Asst/Chief
70% to passWooden shoring, with a cross-sectional dimension of 4" X 4" should not be longer than _______________.
A8 feet
B10 feet
C16 feet
D20 feet
AI Explanation
The correct answer is B) 10 feet. The length limit for 4" x 4" wooden shoring is 10 feet according to the regulations governing the US Coast Guard Captain's License Examinations. This is because wooden shoring of this size and longer runs the risk of bending or buckling under the weight it is intended to support, potentially causing a safety hazard. The other answer choices are incorrect as they either exceed the 10-foot limit (C and D) or are too short (A) for effective shoring applications.
