WHAT IS A HAZARDOUS WASTE?
Hazardous by Characteristic*
Toxic
Poisons, mutagens, carcinogens, controlled substances, dyes, stains,
mercury and other heavy metals..
Reactive
Sulfides, cyanides, explosives, substances that react violently with air,
water and/or produce toxic gas or vapors
Corrosive
Strong acids, strong bases, peroxides.
Ignitable
Liquids – acetone, toluene, most solvents; Gasses - hydrogen,
methane, ethylene; Solids - aluminum powder, nitrocellulose.
Oxidizer
Diethyl ether, inorganic peroxides, nitrate compounds.
Silver Containing
Photo fixer, developer, x-ray film.
*Including paper and rags used to clean spills.
WHAT IS A HAZARDOUS
WASTE?, Cont’d……….
Hazardous by EPA Listing*
Under the Resource Conservation and Recovery Act (RCRA), and
defined in 40 CFR 261 (Code of Federal Regulations), a solid waste
that, because of quantity, concentration, or physical, chemical, or
infectious characteristics: (a) causes or significantly increases
mortality or serious irreversible or incapacitating reversible illness, or
(b) poses a substantial present or potential hazard to human health or
the environment when improperly managed. About 400 wastes are
listed.
EPA also regulates certain materials mixed with hazardous waste
regardless of the percentage, and those derived from hazardous
waste. Examples of derivatives are: sludges, residues, or ashes.
*State and local regulations may also apply
Hazardous Waste
Determination
• The EPA lists some 400 hazardous wastes.
The descriptions are found in 40 CFR Part
261, subpart 261, Sections 261.31-33.
Such as “F” listed, “K” listed, “P” listed,
also.
• Wastes may be hazardous if they display
an of four characteristics: ignitability,
corrosiveness, reactivity, or toxicity (TCLP
regulatory levels, e.g., benzene is 0.5mg/l.
EPA Hazardous Wastes
Listed Hazardous Wastes:
•
“F”- listed-nonspecific sources,
spent solvents
•
“K”- listed-specific industries
•
“P”-listed-acutely hazardous,
sodium azide
•
“U”- listed-unused off-spec. lie
acrylamide (007)
Characteristic Hazardous Wastes (D001D0043):
•
•
•
•
Ignitability: hazardous because
they may ignite, e.g., EPA Haz. No.
D001 organic solvents, oxidizers
Corrosivity: liquids like strong
acids and bases (D002)
Reactivity: solids that react
violently, e.g., picric acid,
peroxides, elemental sodium
(D003)
Toxicity: based on toxic
properties, 8 metals and 32
organic compounds, like As,Hg, PB,
Ba,Ag, benzene, chloroform, vinyl
chloride.(D004-D0043)
