When a staff person is unconscious at the worksite, what should be the immediate action taken?

The recommended immediate action when a staff person is unconscious at the worksite is for them to lie still until medical help arrives. This approach is vital because moving an unconscious person can potentially cause further injury, especially if there is a risk of a spinal injury or other trauma.

By remaining still, the individual is less likely to exacerbate any existing conditions. It is essential to assess the person's breathing and check for any signs of responsiveness. Before initiating any active intervention, such as positioning or administering CPR, ensuring the wellbeing of the surrounding environment and calling for emergency assistance is crucial. This allows trained professionals to arrive with the proper equipment and knowledge to handle the situation safely.

The other approaches, such as moving the individual or administering CPR without determining if it is necessary, could introduce additional risks or complications. Therefore, maintaining stillness until help arrives is the most prudent course of action.
