Can curling irons containing hydrocarbon gas be carried aboard company aircraft?

Curling irons that contain hydrocarbon gas can indeed be carried aboard company aircraft if they are fitted with a safety cover. This requirement is in place to mitigate risks associated with the flammable nature of hydrocarbon gases. The safety cover helps prevent accidental ignition and reduces the risk of fire, ensuring adherence to safety regulations during the flight.

It's crucial for passengers to comply with these safety measures to maintain a secure environment onboard. Not fitting a safety cover, or carrying devices without it, would pose significant safety concerns, which is why the option that stipulates this requirement is deemed correct.
