Good morning Acadiana!
If you guessed a Class 8 Corrosive Substance Label, ding ding ding!
What is Class 8: Corrosive Material?
According to the U.S. DOT definition, Class 8 chemicals are substances that can cause complete destruction of human skin or severe corrosion of stable metals, such as steel and aluminum. They are found in solid, liquid, or gaseous states, and their destructive effects don't end with human handling - packaging, transferring, storing, or containing, and even automobile components are not spared.
Key Features Of Class 8 Hazardous Materials Include
These are typically extremely reactive with organic tissue (they often result in burns, blisters, and irreversible tissue damage)
They are also quite corrosive to metals, leading to structural damage and serious deterioration
Can emit toxic fumes and gases when exposed to water or other liquids or chemicals
Usually exothermic, they release heat when they react
Class 8 Corrosive Substances: Typical Examples In Daily Life
As per typical DOT Supervisor Training, corrosives are not rare. In fact, many are employed in industries ranging from agriculture to the pharmaceutical industry, and nearly all kinds of supervisors and handlers contribute in some way when handling them. Some of the most well-known examples are:
Acids
Sulfuric Acid: Car batteries; extremely hazardous to the touch
Hydrochloric Acid: Utilized in cleaning as well as industrial processing
Nitric Acid: Highly oxidizing and highly corrosive, of course
Bases (Alkalis)
Sodium Hydroxide (Caustic Soda): Drain cleaners easily with them (yeah, we do)
Potassium Hydroxide: Soap-making process
Ammonium Hydroxide: Agricultural fertilizers, industrial applications
Good Morning Acadiana, and Happy Fun Fact Friday!
