Final answer:
When storing flammable materials, it's essential to keep them at a safe distance from any ignition source, follow lab safety rules such as securing loose clothing and hair, and work in a well-ventilated space.
Step-by-step explanation:
When storing flammable materials, it is crucial to maintain a safe distance from any ignition source to prevent accidental fires or explosions. While specific distances can vary based on regulations and the properties of the material, the key principle is to follow your teacher's instructions carefully on how to handle flammable chemicals and to ensure that no chemical is exposed to a flame or other heat source unless specified.
Working with Bunsen burners requires caution. An important safety precaution is to ensure that there are no flammable substances in the vicinity of the burner. This includes following safety practices such as tucking in loose clothing, tying back long hair, and working in a well-ventilated space. Considering general laboratory safety, one should always have knowledge about the location of fire safety equipment.
Furthermore, a material's flash point—the lowest temperature at which it can vaporize to form an ignitable mixture in air—is a critical factor. Substances with a flash point below 73°F are considered extremely flammable and should be stored with utmost caution. It is implied that a safe distance should be much greater for these materials, as they could ignite at room temperature.
