What should you do after confirming the scene is safe and witnessing a coworker collapse?

After confirming that the scene is safe and witnessing a coworker collapse, the most appropriate immediate action is to check if the victim is responsive. Determining responsiveness is crucial, as it helps assess the level of consciousness and guides subsequent steps of care.

If the victim is unresponsive, this can indicate a serious medical emergency, and it may signal the need for immediate assistance, including calling for help and possibly performing CPR. However, before taking such actions, it is essential to first assess whether the person is awake, alert, or able to respond to you. This step is fundamental in emergency response protocols, as it helps to quickly evaluate the situation and decide on the best course of action to ensure the safety and care of the victim.

Once responsiveness has been assessed, appropriate steps can be taken based on the victim's condition and needs, such as alerting others, calling emergency services, or beginning CPR if necessary.
