If employees suspect that a liquefied petroleum gas (LPG) cylinder is leaking, the best course of action is to leave the area immediately and call authorities. This response prioritizes safety. LPG is highly flammable and poses significant risks of fire and explosion. Evacuating allows everyone to distance themselves from the potential hazard, minimizing the risk of inhalation of harmful fumes or injury from a possible explosion.

Contacting authorities ensures that trained professionals can assess the situation. They have the proper equipment and expertise to handle gas leaks safely and effectively. This protocol reflects standard safety practices when dealing with hazardous materials and helps prevent accidents in the workplace.

The other options, while potentially well-intentioned, do not address the immediate safety concerns. Tightening the valve could inadvertently worsen the situation if the leak is severe. Using a lighter to check for leaks is extremely dangerous, as it introduces an open flame to a flammable environment. Continuing to work in the presence of a suspected leak ignores the crucial need for safety and can lead to catastrophic consequences.
