PROJECT2025 Let's get started! We'll study each step one by one. Even if you studied for the exam last year, we'll review it again. The practice questions were selected with recent question trends in mind. The key to this series is that it allows you to experience a balanced range of study material. This time, we've enhanced the solution tips. In the legal section, you'll find a concise explanation of signs and bulletin boards used in hazardous materials facilities, along with practice questions and answer guidance. In the basic physics and chemistry sections, you'll find a concise explanation of fire extinguishing theory and fire extinguishing agents, along with practice questions and answer guidance. [A Little Advice] Are you feeling stressed and not getting anything done because you're short on time? Don't worry. Let's do as much as we can starting now.
