What action must be taken if the rescue service becomes unavailable during an operation?

The correct course of action if the rescue service becomes unavailable during an operation is to notify the employer immediately. This is crucial because the employer needs to be aware of the situation to take appropriate measures to ensure the safety of all workers involved. The availability of a rescue service is a key part of maintaining a safe working environment, particularly in high-risk operations. If the rescue service is compromised, the employer must assess the situation quickly and implement alternative safety measures or halt operations to protect the workers. This proactive communication helps safeguard employees and prevents potential accidents or injuries.

In contrast, failing to notify the employer can leave workers in danger and without an adequate safety plan. Continuing to work without a rescue plan ignores the essential precautions necessary for ensuring safety in potentially hazardous situations. While it may seem logical to exit the area if the rescue service is unavailable, simply informing other workers is not sufficient without involving the employer, who is responsible for overall safety management.
