Characteristics of Hazardous Waste

-

 When it comes to hazardous waste disposal and management, understanding the waste your organization generates is imperative. Hazardous waste is heavily regulated, and thus cannot just be tossed out with your everyday trash. To know if your organization is handling hazardous waste, the first step is to assess its characteristics.

If you need help assessing your organization’s waste, visit us at www.nssihouston.com. We specialize in providing businesses and organizations with affordable nationwide hazardous waste disposal services.

When categorizing hazardous waste, the EPA breaks it down by four characteristics:

  • Ignitability
  • Corrosivity
  • Reactivity
  • Toxicity

1.     IGNITABILITY

There are three types of ignitable forms:

  • Liquids with a flash point–the lowest temperature at which fumes above waste ignite–of 60 degrees Celsius or 140 degrees Fahrenheit. Examples include alcohol, gasoline, and acetone.
  • Solids that spontaneously combust.
  • Oxidizers and compressed gasses.

2.     CORROSIVITY

Corrosive substances, such as hydrochloric acid, nitric acid, and sulfuric acid, have the ability eat through containers, causing the leakage of harmful materials. A corrosive is anything liquid with a pH of less than or equal to 2 or greater than or equal to 12.5, or has the ability to corrode steel. Everyday example of corrosives includes battery acid and rust removers.

3.     REACTIVITY

Given their instability, reactive wastes can be very dangerous. The EPA recognizes that there are too many conditions and situations to identify all types of reactive materials. However, they use the following as guidelines to assist generators:

  • unstable, and routinely experiences violent change without detonating
  • potential for explosive mixture or violent reaction when combined with water
  • toxic gasses are released when mixed with water

4.     TOXICITY

Poisonous materials pose a threat to our groundwater, which can have long term effects to human health and the environment. This is different from the first three characteristic groups, which the EPA views as containing immediate and firsthand dangers. There are 60 contaminants on the toxicity characteristics list. These contaminants are identified solely through a test method called Toxicity Characteristic Leaching Procedure or TCLP.

As a generator of any the above, you have two options to determine which characteristics above best define the waste you generate: test it, or use applied knowledge from previous company records or industry data and studies.

TRITIUM RECYCLING

 NSSI provides Tritium recovery services in excess of 99% of the contained Tritium for reuse and resale as an alternative to the land disposal of high Tritium content materials at its hazardous, mixed and radioactive waste processing center.  NSSI is currently accepting electron capture detectors, static devices, sealed neutron generator tubes and target assemblies with activities ranging from milli curies to multiple Curies. Tritium is a major problem from a land disposal standpoint as Tritium exchanges readily with ground water and tends to move easily through geologic structures. Land disposal sites limit the Tritium activity of incoming wastes to 1 micro Curie per cubic centimeter unless expensive over pack containers are utilized. As a result, Tritium generators are searching for alternatives to land disposal in order to protect the environment, limit operational expenses, and avoid future liabilities associated with the remediation of sites which have Tritium mobility problems
