Safety Symbols at Home and Work

2. HHPS – Household Hazardous Product Symbols
Hazardous Household Product Symbols are found:
On products that the public can buy in the store
Only in the USA and Canada (Other countries have their own set of symbols)

3. HHPS: Household Hazardous Product Symbols
These symbols are made up of a picture and a frame:
The picture tells you the type of danger.
The frame tells you
if it is the chemical inside the container that is hazardous
if it is the container that is hazardous.
Dangerous contents in container Dangerous container
                                                                                                                    
Poison       Flammable     Explosive        Corrosive

4. HHPS: Household Hazardous Product Symbols
Before October 1, 2001 the old regulations required three different frames (Yield sign, diamond and stop sigh) to indicate the degree of hazard. Now, only two frames are used to distinguish between the contents of the product and the container itself.

5. Symbol The Danger Product examples

See your handouts!

10. CLASS A: COMPRESSED GAS
This class includes compressed gases, dissolved gases, and gases liquefied by compression or refrigeration.
CLASS B: FLAMMABLE AND COMBUSTIBLE MATERIAL
This class includes solids, liquids, and gases capable of catching fire in the presence of a spark or open flame under normal working conditions.
CLASS C: OXIDIZING MATERIAL
These materials increase the risk of fire if they come in contact with flammable or combustible materials.

11. CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 1: Materials Causing Immediate and Serious Toxic Effects
These materials can cause death or immediate injury when a person is exposed to small amounts.
CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 2: Materials Causing Other Toxic EFFECTS
These materials can cause life-threatening and serious long-term health problems as well as less severe but immediate reactions in a person who is repeatedly exposed to small amounts.
CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 3: Biohazardous Infectious MATERIAL
These materials contain an organism that has been shown to cause disease or to be a probable cause of disease in persons or animals.

12. CLASS E: CORROSIVE MATERIAL
This class includes caustic and acid materials that can destroy the skin or eat through metals. Examples: sodium hydroxide, hydrochloric acid, nitric acid
CLASS F: DANGEROUSLY REACTIVE MATERIAL
These products may self-react dangerously (for example, they may explode) upon standing or when exposed to physical shock or to increased pressure or temperature, or they emit toxic gases when exposed to water.
