When is it acceptable to remove the inner thermal layer from a turnout coat?

The correct response highlights that the inner thermal layer of a turnout coat should be removed only during cleaning. This is essential because the inner thermal layer is designed to provide insulation and protection from heat, ensuring the firefighter's safety in high-temperature environments. Removing this layer for cleaning allows the firefighter to maintain the integrity of the coat while ensuring it remains hygienic and effective.

Choosing to remove the inner layer for other reasons, such as during training, when not in use, or for ventilation during a fire, compromises the protective functions of the turnout gear. Training scenarios should simulate real-life conditions as closely as possible, which means wearing the complete turnout gear. Ventilation is ideally managed through other means, such as adjusting the outer layers or using well-established techniques without removing critical protective elements.
