Hazardous Waste Class 8 - Corrosive Liquids

Posted by author Richard Espinoza on Fri, Jul 20, 2018

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.

hazardous waste class 8Corrosives 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.

 

What Are Class 8 Liquids?

 

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

The U.S. Code of Federal Regulations divides Class 8 Corrosives into three packing groups according to their degree of hazard in transport . Packing Group I indicates great danger; Packing Group II, medium danger; Packing Group III, minor danger. 

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 IIMaterials 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 IIIMaterials, other than those meeting Packing Group I or II criteria:

  1. 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 60 minutes but not more than 4 hours; or
  2. That do not cause full thickness destruction of intact skin tissue but exhibit a corrosion rate on steel or aluminum surfaces exceeding 6.25 mm (0.25 inch) a year at a test temperature of 55°C (130°F).

Why Dispose Professionally?

 

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.

 

What Are the Hazards of a Class 8 Spill?

 

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.
