Final answer:
Students must strictly adhere to instructions when handling class 1.1, 1.2, or 1.3 explosives, and ensure that these materials are never exposed to flames or heat unless instructed by a teacher.
Step-by-step explanation:
The correct answer is students must follow the instructions carefully when handling class 1.1, 1.2, or 1.3 explosives. These materials are highly dangerous and could cause severe damage if not treated properly. It is essential to avoid exposing the chemicals to any flame or heat sources unless it has been explicitly stated as safe by an authoritative figure, such as your teacher.
Furthermore, good practice for safety involves always having the proper material for raising fire available but keeping it in a state of readiness to prevent any accidental ignition.
The correct answer is option to follow the instructions carefully on how to handle flammable chemicals. When carrying class 1.1, 1.2, or 1.3 explosives, it is crucial to be cautious and ensure proper safety measures are taken. In chemistry, these classifications correspond to different types of explosives and their levels of danger.
For example, class 1.1 explosives are substances that have a mass explosion hazard, while class 1.2 explosives have a projection hazard. Class 1.3 explosives, on the other hand, have a minor explosion hazard. To ensure safety, it is essential to follow the guidelines provided by your teacher or instructor.
