2. Science Laboratory: Symbols, Signs and their Meanings • If you have ever visited a science laboratory, you must have come across several symbols and signs displayed on the walls or near science equipment. A science laboratory is a place which is exposed to harmful substances since a number of experiments are conducted there. Hence, as a science lab visitor, you should be aware of these symbols. • Here is your handy guide to decoding the meaning of symbols in a science lab Science Laboratory: Symbols, Signs and their Meanings

3. Corrosive This sign indicates the presence of corrosive substances that can burn your skin to the bone if you come in direct contact with them.

When you see this sign, you should wear a face mask and anti-bacterial gloves in the lab.

6. High Voltage The science equipment bearing this sign indicates that it runs on high voltage. The electricity power is so high that it can cause bodily harm or death to any living being.
