What is the first action to take when trying to gain access to the subject?

Making voice contact with the subject is the first action to take when trying to gain access because it establishes communication, which is crucial for assessing the situation. This step allows the rescuer to gauge the subject's condition, determine their needs, and provide reassurance. Through voice contact, the rescuer can also confirm that the subject is conscious and responsive, which helps to inform subsequent actions.

Additionally, making voice contact can help to calm a panicked subject, allowing them to provide critical information about their circumstances. This can include details about their injuries, environment, or any immediate dangers. While assessing the safety of the area and preparing rescue equipment are also important, initiating communication with the subject is vital for ensuring an effective and safe rescue operation.
