These could be to warn you of dangerous materials or behaviour. (acids running)
They could be to advise of safety procedures. (Fire escape, eye wash, first aid.)
They could be to aid you in using safety equipment. (fume cupboard, fire extinguisher)

The safety symbols used in a laboratory would depend on what kind of lab it is and what activities are pursued in the lab. There is no universal set of safety symbols suitable for all laboratories.
Laboratory symbols are symbols you find inside a laboratory, obviously. They are used to give a warning or precaution to the users of the lab. They also aid in the systematic flow of experiments and safe contact with unfamiliar chemicals.
This question refers to laboratory safety signals. Two common symbols are the bio-hazard (multiple slashes), and radioactive/radiological which uses stacked triangles.
Pictures of laboratory signs and symbols can be found in a simple image search on the internet. Pictures of this can also be found inside a science book.

There are several printed signs in a laboratory that ask for hands to be washed upon entering and leaving the lab. There are also signs that display a person at a sink washing their hands.

The general warning lab safety symbol consists of a black exclamation point in a yellow triangle. As you'd expect, it is a general warning to laboratory staff that a hazard exists.
Some safety precautions n a computer lab would be: do not have trailing wires or cables; do not write down and stick on the PC any username and password combinations; obey health and safety regulations for that lab. It is also important to know where the fire exits are and where the correct fire extinguishers are.
