Which type of training structure must have their thermal linings inspected regularly?

Regular inspection of thermal linings in training structures is crucial for ensuring safety and effectiveness during live fire training exercises. Thermal linings serve to protect the structure from extreme heat and thermal damage, which can compromise the integrity of the building materials and pose risks to instructors and trainees.

In both gas-fired and non-gas-fired structures, the thermal linings help to contain heat and minimize fire spread outside the designated training areas. Over time, thermal linings can wear down due to exposure to high temperatures and repeated training sessions. Regular inspections are necessary to identify any degradation, such as cracking or peeling, which could compromise the structure's fire safety performance.

By mandating inspections for both types of structures, it ensures a comprehensive safety protocol that accounts for various training environments and practices. This proactive approach reduces the risk of incidents during training, thereby safeguarding all participants and maintaining compliance with safety regulations.
