dịchNgồi quanh đống lửa trại là một cách thú vị để thư giãn sau một ngày đi bộ đường dài. Thật không may, nhiều trại viên không biết cách giữ lửa an toàn. Rừng rất dễ bắt lửa nhưng để ngăn cháy rừng thì vô cùng khó. Hàng năm, cháy rừng thiêu rụi thực vật, giết hại động vật, tàn phá môi trường và đe dọa cuộc sống của con người. Điều quan trọng là khi xảy ra hỏa hoạn, bạn nên làm nơi chữa cháy an toàn.
Đây là một số nguyên tắc cần nhớ: 1. Chọn một nơi an toàn cho đám cháy của bạn. Di chuyển tất cả những thứ dễ bắt lửa cách xa lửa trại của bạn ít nhất 1 mét. 2. Khi lửa trại đang cháy, một người nào đó trong nhóm của bạn nên xem để đảm bảo lửa không lan rộng. 3. Chuẩn bị sẵn một cái xẻng để đề phòng trường hợp bạn cần dập lửa. 4. Khi bạn không muốn sử dụng lửa nữa, hãy đổ nước vào lửa cho đến khi nó hoàn toàn
