Proper ventilation is really important for keeping everyone safe during chemical experiments in Year 1. Here are a few reasons why:
Less Harmful Fumes: Many chemicals give off bad fumes that can hurt our health. For example, just a small amount of formaldehyde can cause problems, even at 0.1 parts per million (ppm), which is a tiny amount.
Dilution of Dangers: Good airflow helps to spread out these dangerous substances quickly. When we have more air flowing in, it can lower the amount of harmful chemicals by about 60% each time we double the airflow.
Lower Risk of Accidents: When air moves well, it helps to prevent flammable vapors from building up. For some chemicals, like acetylene, the risk of explosions can start at just 2.5% in the air.
To sum it up, making sure we have proper ventilation is crucial for keeping the laboratory safe for all students.
