レビューをお寄せいただき、誠にありがとうございます。 ご指摘のとおり、丙種では取り扱わない危険物（鉄粉・硫黄・ナトリウムなど）の指定数量を問う問題が含まれておりました。学習の妨げとなってしまい、申し訳ございませんでした。 該当する20問を、丙種で取り扱える危険物（ガソリン・灯油・軽油・重油など）の範囲や、複数の危険物を貯蔵するときの指定数量の倍数を求める問題に差し替えました。次にアプリを開いていただいた際に、アップデートなしで反映されます。 なお、鉄粉は第2類の危険物のうち独立した品名で、引火性固体とは別に指定数量（500kg）が定められております（危険物の規制に関する政令 別表第三）。 今後も試験の範囲に沿った問題となるよう見直してまいります。お気づきの点がございましたら、問題画面の「誤りを報告」からもお知らせいただけますと幸いです。引き続きよろしくお願いいたします。
