Smelling or tasting substances in a science lab puts you at risk of injury or death if the substance is a hazardous substance.
In past centuries this was one way that scientists figured out what an unknown substance was, or tried to describe it so others could do that. Now, there are more effective and efficient means of identifying unknowns and the risk of absorbing something hazardous is no longer acceptable.
You may spill something dangerous into them and you need to pay attention to what you are doing. Eating or drinking while doing lab experiments is as bad as texting while driving. You need to do one or the other.
because at the lab there are some chemicals which are toxic and as we bring food or water into the lab our food may come contact with these items and as a result we may eat or drink it.
There are no safety procedures for tasting and smelling substances in the science room. That is something you should never intentionally do.
because it is dangerous
There is no symbol for "never taste or smell an unknown substance" because that is a universal precaution that everyone should be taught.
