Final answer:
In a laboratory setting, it is generally recommended to keep flammable liquids at least 10 feet away from an ignition source to prevent accidental fires. Laboratory safety also includes additional precautions such as securing loose clothing and ensuring proper ventilation while working with open flames.
Step-by-step explanation:
The minimum distance that flammable liquids should be kept away from an ignition source varies depending on specific regulations and contexts. However, in many cases, such as a laboratory environment, a common practice is to maintain a safe distance of at least 10 feet from an ignition source. This practice helps to prevent the ignition of flammable vapors that can be released by the liquids. Flash points of substances give an indication of how easily a chemical might ignite; the lower the flash point, the more easily it could catch fire at lower temperatures.
When working with Bunsen burners or during laboratory experiments, it is important to keep flammable substances at a safe distance. This is to prevent accidental fires, which can be exacerbated by the substances' ability to release large amounts of energy when burned, as suggested by the calculation involving the energy release of burning crude oil. Additional safety tips include tying back loose hair, using protective clothing, and ensuring proper ventilation in the space.
