Question 1478 Deck General

The correct answer is B) flammability. Liquefied petroleum gas (LPG) and liquefied natural gas (LNG) are highly flammable due to the nature of their chemical composition. These gases become liquefied under pressure, and their primary hazard is the risk of fire or explosion if they are released and come into contact with an ignition source. The extreme flammability of LPG and LNG makes them potentially dangerous if not handled and stored properly. The other options are incorrect because while toxicity, temperature, and pressure are also important considerations, the primary hazard of these liquefied gases is their flammability, which poses the greatest risk to safety.
