Question 3622 Deck General

The correct answer is B) 3 to 1. The factor of safety based on the elastic limit of the material for the forks used on power operated industrial trucks aboard a MODU (Mobile Offshore Drilling Unit) must be at least 3 to 1. This requirement is specified in 46 CFR 109.437, which states that the forks must have a safety factor of 3 to 1 based on the ultimate strength of the material. The other options are incorrect because 2 to 1 (A) would not provide enough safety margin, while 4 to 1 (C) and 5 to 1 (D) would be overly conservative and unnecessary for this application.
