How often should fire shelters be inspected?

The correct answer emphasizes the importance of regular inspections to ensure that fire shelters are in proper working condition and ready for use when needed. Inspections should occur when the shelter is first issued, at the start of the fire season, and then every two weeks. This schedule ensures that any wear, damage, or degradation that could affect the shelter's performance is identified and addressed in a timely manner.

The rationale is based on the need for safety during fire operations, as fire shelters are critical lifesaving gear. Ensuring that they are functional and undamaged at the start of the season and periodically during the season helps mitigate risks associated with fire emergencies.

In contrast, the other options don't provide adequate frequency for inspections. Relying on inspections just at the start of the fire season overlooks potential issues that could arise during use. Monthly checks may not catch problems early enough to ensure readiness. Weekly inspections throughout the year may be excessive and not practical for most operational scenarios, given the seasonal nature of wildland firefighting.
