Ignitable waste

Potassium permanganate under RCRA definition meets the criteria of an ignitable waste, and if discarded is considered a ha2ardous waste. The reportable quantity (RQ) (220) for potassium permanganate is 45.4 kg (100 lbs) and releases into the environment greater than this value must be reported to the U.S. Coast Guard National Response Center. 

Standard for gauging flammability. The most common systems for designating flammability are the Department of Transportation (DOT) definitions, the National Fire Protection Association s (NFPA) system, and the Environmental Protection Agency s (EPA) Resource Conservation and Recovery Act s (RCRA) definition of ignitable wastes, all of which use flashpoint in their schemes. The NFPA diamond, which comprises the backbone of the NFPA Hazard Signal System, uses a four-quadrant diamond to display the...

Where this value is known it is an excellent measure of the relative hazard of a flammable liquid. Unfortunately, it is available in only a few instances Susceptibility to Spontaneous Heating. Many materials combine with atmospheric oxygen at ordinary temperatures and liberate heat. If the heat is evolved faster than it is dissipated due to poor housekeeping, a fire can start, particularly in the presence of easily ignited waste, etc. [ Factory Mutual Modified Mackey Method, Industrial and Engineering Chemistry (March 1927)] Explosive Range or Flammability Limits. 

Ignitable Waste A liquid with a flash point less than 60°C (140°F), a waste which is an oxidizer, or ignitable compressed gas or non-liquid which is liable to cause fires through friction, absorption of moisture, spontaneous chemical changes or when ignited bums so vigorously and persistently as to create a hazard.

Hazardous wastes are either listed wastes (40 CFR 261.30-.33) or characteristic wastes (40 CFR 261.21-.24). The U.S. EPA defines four characteristics for hazardous waste ignitability (40 CFR 260.21) corrosivity (40 CFR 260.22) reactivity (40 CFR 260.23) and toxicity (40 CFR 260.24). Any waste that exhibits one or more of these characteristics is classified as hazardous under RCRA. The ignitability definition includes a liquid that has a flash point less than 60 C (140 F) the EPA included ignitability to identify wastes that could cause fires during transport, storage, or disposal (e.g., used solvents). All of the solvents in Table 14.10.5 have flashpoints less than 60 C, so all could be a RCRA ignitability waste. 

Under the Clean Water Act, some exemption from regulation as a hazardous waste for wastewater containing laboratory-generated listed waste is allowed. In 1993, this exemption was expanded to include corrosive and ignitable wastes. For the exemption to apply, these laboratory wastes must be 1% or less of the annual total wastewater quantity reaching the facility s headworks or have an annualized average concentration of no more than 1 part per million (ppm) of the wastewater generated by the facility.

The remainder of wastes consists of reactive wastes corrosive wastes toxic wastes ignitable wastes and P wastes (discarded commercial chemical products, off-specification species, containers, and spill residues), U wastes, and unspecified types. 

The HCl produced in this reaction is recycled to be used in the first reaction by oxidation of the hydrogen-chlorine bond. Ethylene dichloride is produced domestically by ten manufacturers. Approximately 1.2 billion lbs. is produced in the United States per year. In 1989 nine million pounds of 1,2-Dichloroethane were released as pollution, 43.22% into the air, 2.34% into surface water,. 01% onto land, 11.01% underground, 16% into public sewage, and 27.43% off site. Its EPA hazardous waste classification is DOOl (ignitable waste), and its DOT hazard class is flammable liquid, with a reportable quantity of 5000 lbs. It should be stored in a cool, dry, well-ventilated flammable liquid storage area, away from oxidizers, strong acids, chemically active metals, strong caustics, and dimethyl-aminopropylamine, as violent reaction can occur. 

They are easily combustible or flammable. Examples of such ignitable wastes are paint wastes, certain degreasers, and other solvents.
