The level of activity required to be considered an "active" volunteer firefighter can vary depending on the policies and expectations of the specific fire department or fire company. However, typically, an active volunteer firefighter is someone who regularly participates in training sessions, attends meetings, responds to emergency calls, and contributes to the overall functioning of the fire department or company.

Here are some common criteria that might be used to determine the level of activity:

1. Training Participation: Active volunteers often attend training sessions regularly to maintain and improve their firefighting skills. This could include both classroom instruction and hands-on drills.

2. Response to Calls: Active volunteers are expected to respond to a certain percentage of emergency calls based on the department's requirements. This ensures that there are enough personnel available to handle various types of emergencies.

3. Meeting Attendance: Active volunteers typically attend department meetings where important information is shared, decisions are made, and training schedules are discussed.

4. Participation in Community Events: Some fire departments require volunteers to participate in community events and outreach programs to raise awareness about fire safety and the role of the fire department in the community.

5. Maintenance of Equipment and Facilities: Active volunteers may be involved in tasks such as equipment checks, maintenance, and cleaning of fire stations and apparatus.

6. Involvement in Department Activities: This could include involvement in fundraising efforts, recruitment drives, or other department initiatives.

Ultimately, the definition of "active" volunteering in firefighting can vary from one department to another, but it generally involves regular participation in the activities and responsibilities of the fire service.
