What is the first action to take in case of a gas leak during the handling of compressed gases?

In the event of a gas leak while handling compressed gases, the first and most critical action is to shut off the gas supply and evacuate the area. This response is essential for several reasons.

When there is a gas leak, the potential for an explosion or a hazardous situation increases significantly. By shutting off the gas supply, you are directly addressing the immediate source of danger, which helps prevent a worsening of the situation. Following this, evacuating the area ensures that all individuals are moved to a safe distance away from the leak, minimizing the risk of exposure to harmful gases or potential fire hazards.

This protocol aligns with safety regulations and best practices for handling hazardous materials, which emphasize containment and isolation in emergencies. Addressing the source of the leak quickly is essential for maintaining safety and preventing potential accidents.

The other choices do not prioritize immediate safety effectively. Running away may not address the leak itself and could leave others in danger; seeking help from a coworker delays action and could lead to more significant risks; ignoring the situation is the least safe option and poses a high risk of injury or catastrophe.
