In-service drills typically occur:

In-service drills are structured training exercises designed to enhance the skills and coordination of responders. They often take place at a specified location because this allows participants to practice in an environment that simulates the conditions they would face during actual incidents. Conducting drills in a controlled, designated area ensures that the training is relevant and practical, which enhances the effectiveness of the exercise.

While drills may have specific times and personnel involved, the key factor is the location, which provides a practical context for the training. Utilizing a set location helps responders familiarize themselves with the space, leading to improved performance during real-life situations. It is essential for responders to learn how to navigate and operate effectively in the environments where they will be responding to emergencies. Thus, focusing on a specified location is critical in the execution of effective in-service drills.
