Question 69 TV01 - Towing Vessels - Oceans or Near Coastal

The Correct Answer is B *** ### Explanation of Correct Option (B: 160-B) The requirement for semi-portable fire extinguishing systems on inspected and uninspected commercial vessels is generally based on the vessel's gross tonnage (GRT). The classification "B" indicates that the extinguisher is rated for flammable liquid fires (such as fuel or oil). The number preceding the "B" classification (e.g., 160) indicates the minimum required size/quantity of extinguishing agent for the unit. Your vessel has the following characteristics: 1. **Uninspected Towing Vessel (UTV).** 2. **Gross Tonnage (GRT) of 290.** 3. **Construction contracted for after August 27, 2003** (meaning it falls under modern regulatory standards regarding safety equipment). According to US Coast Guard regulations (applicable to vessels of this size, typically found in 46 CFR), a vessel ranging from **100 GRT up to 1000 GRT** is required to carry a **160-B** classification semi-portable fire extinguishing system. Since 290 GRT falls within this range, a 160-B unit is required. *** ### Explanation of Incorrect Options **A) 150-B:** This is not a recognized or standard size classification used in USCG regulations for required semi-portable fire extinguishing systems. Required standard sizes jump from 120-B directly to 160-B in this tonnage category. **C) 140-B:** Similar to 150-B, this is not a recognized or standard size classification used in USCG regulations for required semi-portable fire extinguishing systems. **D) None of the above:** This is incorrect because the 160-B system is specifically required for a vessel operating in the 100 GRT to 1000 GRT range.
