Compressed Gas

Front 2

What is Compressed Gas?

Back 2

A gas at normal temperature and pressure, packaged under pressure in a cylinder or other container. Many of our laboratories and work areas use cylinders of various sizes and content such as compressed air, hydrogen or nitrogen.

Flammable and Combustible Materials

Front 4

What is Flammable and Combustible Materials?

Back 4

Classifying material that will ignite and continue to burn in air if exposed to a source of ignition. This class includes gases, aerosols, liquids and solids. Many laboratory solvents and cleaning materials used on campus fall into this class.

Oxidizing Materials

Front 6

What is Oxidizing Materials?

Back 6

This symbol identifies material that releases oxygen or other oxidizing substances and thereby contributing to the combustion of other flammable materials. Oxidizers such as chlorine, nitrogen dioxide and hydrogen peroxide are found in many of our laboratories.

Corrosive Material

Front 11

What is Corrosive Material?

Back 11

Corrosive material can attack metals and other substances and can cause permanent damage to human tissues and organs. Fumes from these material can also damage our internal organs. Strong acids, ammonia and fluorine are examples of corrosives.

What is Class D Division 1: Materials Causing Immediate and Serious Toxic Effects?

Back 12

The skull and cross bones identifies acutely toxic material. These materials can severely damage our health in a single overexposure. Fortunately, few of our work areas contain this type of material. Examples are cyanide compounds, styrene.

What is Class D Division 2:Materials Causing Other Toxic Effects?

Back 13

This unique symbol identifies material that poses a threat to our health through long term exposure. Further, this material may be a suspected carcinogen or have other health damaging properties. Our labs, work areas and shops contain materials marked with symbol.

What is Class D Division 3:Biohazardous Infectious Material?

Back 14

This distinctive symbol identifies material that presents the risk or danger of biological or viral infection on contact. Very few areas of the University use or produce material marked with this symbol. Containers for biomedical waste and used syringes, needles and sharps are marked with this symbol.

Dangerously Reactive Material

Front 16

What is Dangerously Reactive Material?

Back 16

This symbol identifies dangerously reactive materials. These materials may react violently under certain conditions or react violently with water. Few of our work areas use or store these materials.
