Chemical Hazard Information and Definitions

Flame over Circle

a

This symbol on a chemical label means that the substance is an oxidizer. Oxidizers may cause a fire by increasing the concentration of oxygen in the air.

Skull and Crossbones

adding Bottles to a Chemical Record

Substances with a hazard of acute toxicity will have this symbol on their chemical label. Acute toxicity means that exposure to a single dose of the chemical may be toxic or fatal if inhaled or swallowed, or if it comes into contact with the skin.

 

Corrosion

adding Bottles to a Chemical Record

This pictogram on a chemical label means that the substance causes skin burns, eye damage, or destroys metals

Exclamation Mark

a

It is used on a chemical label for substances that represent the following hazards:

  • Irritant–irritates the skin or eyes;
  • Skin sensitizer–which is an allergic response following skin contact;
  • Acute toxicity–which may be fatal or cause organ damage from a single short-term exposure;
  • Narcotic effects like drowsiness, lack of coordination, and dizziness; and
  • Respiratory tract irritation.

Flame

adding Bottles to a Chemical Record

It appears on chemical labels for substances that are:

  • Flammables–which are gases, aerosols, liquids, or solids that will burn or ignite under certain conditions,
  • Self-Reactives–heating alone, without air, may cause fire or explosion,
  • Pyrophorics–in small amounts, may ignite within 5 minutes after contact with air,
  • Self-Heating–which may catch fire only in large amounts and after long periods of time when exposed to air,
  • Emitters of flammable gas, and
  • Organic peroxides–which, when heated, may cause fire or explosion; may be sensitive to impact or friction; and may react dangerously with other chemicals.

Exploding Bomb

adding Bottles to a Chemical Record

The exploding bomb pictogram appears on the chemical labels of substances that are:

  • Explosives—which is a solid or liquid chemical capable of a chemical reaction that causes damage to the surroundings,
  • Self-Reactive—heating may cause fire or explosion without the need for air, or
  • Organic peroxides—again, heating may cause fire or explosion.

Gas Cylinder

a

This pictogram on a chemical label means that the substance is a compressed, liquefied, or dissolved gas under pressure at 29 pounds per square inch or more.

Personal Protective Equipment Definitions

Eye Protection

adding Bottles to a Chemical Record

Special Hazard Definitions

Biosafety Hazard

adding Bottles to a Chemical Record

Potential biohazardous materials are located in this space.

Laser Radiation

adding Bottles to a Chemical Record

The use of laser equipment is used in this space.

Flying Particles

adding Bottles to a Chemical Record

Risk of flying projectiles while equipment is operating in this space.

Sharp Objects

adding Bottles to a Chemical Record

Risk of sharp objects in this space.

Rotating Equipment

a

Rotating equipment in operation which will pose a personal safety risk.

Radiation

adding Bottles to a Chemical Record

The high energy emission of energy as electromagnetic waves or moving subatomic particles.

Strong Magnetic Field

adding Bottles to a Chemical Record

An invisible field that exerts a magnetic force on substances which are sensitive to magnetism.

Pressure - Vacuum

adding Bottles to a Chemical Record

Equipment in the space operates either under pressure or vacuum potentially causing an explosion. 

Electric Shock

adding Bottles to a Chemical Record

Potential equipment which could deliver a dangerous level of electricity to the body.

Pinch Point

adding Bottles to a Chemical Record

Pinch points are points in and around machinery where there is a chance of a body part getting caught between a stationary and a moving part of a machine.

Asphyxiation

adding Bottles to a Chemical Record

Conditions could be present where oxygen could be displaced resulting in suffocation.

UV Light

adding Bottles to a Chemical Record

Ultraviolet Radiation present in the room.

Animal Room

Animal warning

This room houses live mice.  Entering the room could cause severe infection to the animals in this facility.  Please ask the laboratory staff for training before entering the room.
