Poor trailer ventilation can cause cargo to ________.

Poor trailer ventilation can cause cargo to ________.

• A. Catch fire
• B. Spoil
• C. Freeze
• D. Leak

Answer: (A)

Poor ventilation lets heat and flammable vapors build up inside an enclosed trailer. When vapors accumulate and reach a flammable concentration, they can ignite if there’s a spark or hot surface, causing the cargo to catch fire. So the risk most directly tied to lack of ventilation is fire. Spoiling of goods happens mainly from temperature and moisture affecting perishables, freezing involves dropping temperature, and leaks come from openings or damage rather than ventilation.
