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.

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.
• They are also known to cause blindness if they
  fall on your eyes. Hence, you should wear gloves,
  face mask or protective clothing to stay safe
  from these substances in the lab.

• This sign alerts you regarding the location of a
  defibrillator, also known as Automated External

• It is an emergency device to attend emergency
  cardiac arrest cases. It is advisable not to
  touch it unless you are trained or authorized to
  do so.

Biohazards

• Biohazard signs can usually be found near science
  equipment, refrigerator or freezers that usually
  store or use biohazard material such as toxins,
  blood samples, dangerous/infectious bacteria,
  viruses or any other unsafe microorganisms.
• When you see this sign, you should wear a face
  mask and anti-bacterial gloves in the lab.

Hot surface

• 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.
• Either you need to stay clear of such area or
  wear adequate protection and take necessary
