Hazardous waste Class 8 corrosive liquids are usually either strong acids or strong bases and, depending on the compounds within them, can react differently with various metals and polymers.
For companies that use corrosive substances, care must be taken because they will destroy and damage other substances that they come into contact with.
Corrosives may attack a great variety of materials, including metals and various organic compounds. But, of more concern is the damage that they can cause on human skin over a specified amount of time.
Acids and bases vary considerably in their strength, and can generally be measured on a pH scale which ranges from 0 to 14, with pure water being a neutral 7. A strong acid generally has a pH at or under 2, while a strong base will have a pH at or above 12.
Both acids and bases are used in a wide variety of commercial manufacturing and cleaning applications, and their byproducts remain extremely dangerous even after dilution.
Packing Groups for Class 8 Corrosives
Here are the definitions:
Packing Group I - Materials that cause full thickness destruction of intact skin tissue within an observation period of up to 60 minutes starting after the exposure time of three minutes or less.
Packing Group II - Materials other than those meeting Packing Group I criteria that cause full thickness destruction of intact skin tissue within an observation period of up to 14 days starting after the exposure time of more than three minutes but not more than 60 minutes.
Packing Group III - Materials, other than those meeting Packing Group I or II criteria:

The U.S. DOT, the EPA, and the California Department of Toxic Substances Control prohibit corrosive liquids from being disposed of as normal waste.
In order to avoid contaminating the environment, endangering public health, or damaging municipal utilities, a professional hazardous waste management firm will safely contain corrosive liquids in separate, specialized containers.
This will reduce the risk of causing a harmful reaction between incompatible hazardous liquids, and then transport the materials to an EPA-designated landfill or processing plant.
Exposure to corrosive liquids could be catastrophic for employees and any surrounding equipment. It is important to limit your organization’s liability and expenses in the event of a hazardous waste spill.
