Science Safety Symbols
While visiting or while working in a science lab, it is important that one knows all the lab symbols as one wrong step can be dangerous for you as well as for others around you. Given below are some of the symbols that you will notice mainly in a science lab.
Warning or Danger
In some places you will see a yellow board with a black colored triangle around a black exclamation mark. Below the triangle will be a text in black on yellow background.

Radioactive Safety
Radioactive materials are used in science labs and if a person without proper protection comes in contact with radiation, then it might be hazardous. Hence, the symbol of a black circle surrounded by three triangular structures, on a yellow background and embedded within a black triangle, is used as a radioactive safety measure.
Electrical Safety
The symbol is a yellow triangle within a black triangle and the sign of a bolt of lightning in black. It warns people that the area is a high voltage area and that if they enter it without proper precautions, they might get electrocuted.

Flammable and Explosives
Sometimes you will see the signs of a burning fire marked either in red or black on certain machinery or equipment in the science lab. This lab safety sign indicates that the product can catch fire pretty easy and that it's a caution to people not to get anything that causes fire, near the product. The picture of something bursting, indicates that the product is highly explosive hence one has to be very careful around it and that it is recommended that one does not get anything that might cause an explosion, near it.
