Explanation:

1. In case of a laboratory fire, one should first notify the instructor as they are trained to handle such situations and can direct proper response. Running for a fire - extinguisher without proper training can be dangerous, throwing water on some fires (e.g., those involving flammable liquids) can make it worse, and opening windows can fan the flames.
2. Flammable materials like alcohol should never be used or dispensed near an open flame as it can easily ignite.
3. In a laboratory, all chemicals should be considered dangerous as their properties and potential reactions may not be fully known or misidentified, so safety precautions must be high.
