Which type of fires are used to train entry-level students and industrial fire brigade members on how to use portable handheld extinguishers to control all classes of fires?

The correct answer is small prop fires. These types of fires are particularly suited for training entry-level students and industrial fire brigade members because they provide a safe and controlled environment to practice using portable handheld extinguishers. Small prop fires allow trainees to engage in practical exercises that mimic real-life scenarios without the overwhelming size or complexity encountered in larger fire situations.

Using small prop fires helps students learn how to identify various fire classes and apply the appropriate extinguishing techniques effectively. The training provides immediate feedback and safety, ensuring that learners can practice critical skills in a manageable setting. This foundational experience is crucial for building confidence and competence in firefighting practices.

Other types of fires, such as those involving urban interface or medium to large prop fires, may be too complex or hazardous for beginners. They could introduce risks that are not suitable for initial training phases. While flammable and combustible liquid fires are important to address in specialized training, they require specific knowledge and skills that may not be appropriate for entry-level instruction.
