Final answer:
Typically, engines should be off when loading flammable liquids due to ignition risks. Strict safety protocols may allow otherwise under certain conditions. Always follow detailed instructions when handling flammable chemicals.
Step-by-step explanation:
You should generally turn off your engine when loading flammable liquids to prevent the risk of ignition. However, there could be specific circumstances under strict safety protocols where this might not be necessary, as per the instructions provided by your teacher or in a controlled industrial setting. Always consult with instructions carefully when handling flammable chemicals and avoid exposing them to any potential sources of ignition, including flames or spark-generating equipment, unless you've been specifically authorized and instructed on how to do so safely.
When handling flammable liquids, it is important to follow proper safety protocols. One of these protocols is to turn off your engine when loading flammable liquids, unless there are specific instructions from a knowledgeable source like a teacher or supervisor. This is to prevent any ignition source such as a spark from the engine, which could potentially lead to a fire or explosion.
