What is the first step in the procedure for handling an exposure incident?

The first step in handling an exposure incident is to stop the service. This action is crucial as it ensures the immediate safety of both the client and the technician. By stopping the service, you prevent further exposure to any potential hazards, such as blood or bodily fluids that may have led to the incident. It allows for proper protocol to be followed without risking additional injury or contamination.

After stopping the service, the next steps typically involve notifying the supervisor, documenting the incident, and washing hands thoroughly. Each of these steps plays an important role in managing the situation responsibly and ensuring a safe environment for all. However, halting the service initially is vital because it prioritizes the immediate health and safety of those involved.
