Study Notes

Lab Safety Symbols

Lab safety symbols are used to communicate potential hazards in a laboratory setting.

Flammable

Chemicals easily catch fire (ignite) even at room temperature.
Example needed.

Explosive

Chemicals with this symbol shatter easily into pieces if shaken, exposed to heat, or pressure.
Example needed.

Corrosive

Chemicals with this symbol cause serious irreversible damage to living tissue (like skin) or non-living tissue (like a table).
Example needed.

Harmful or Irritant

Non-toxic chemicals that may cause inflammation of the skin, nose, or eyes.

Toxic/Poisonous

Chemicals with this symbol can cause death if swallowed or inhaled.
Example needed.

Biohazard

This symbol describes biological substances that can be dangerous to the health of living organisms, primarily humans.
Example needed.

Environmental Hazard

Can cause significant harm to the environment, like seas and rivers.

Radioactive

This symbol means the powerful and dangerous energy is being emitted or given off. This can permanently damage living organisms.
Example needed.

Additional Safety Symbols

Additional resources list additional symbols for hazards.
Examples include: strong magnetic field, sharp object, hot surface, cold hazard, corrosive substance, electrical hazard, toxic material, flammable material, radiation hazard, biohazard, laser hazard, explosive materials, fire, etc.
Warning, Caution, and Danger signs are also included.
