HAZARDOUS WASTECostales, Hannah Grace

DEFINITION

a waste with properties that make it dangerous or potentially harmful to human health or the environment.

It takes many physical forms and may be solid, semi-solid, liquid, or even contained gases

SOURCES

1) Agricultural land and agro-industry

2) Domestic

3) Mines and mineral processing sites

4) Health care facilities

5) Commercial wastes

6) Institutional hazardous waste sources

7) Industrial hazardous waste sources

8) Solid waste disposal sites

9) Contaminated sites

10)Building materials

TWO CATEGORIES

1. Listed Wastes

2. Characteristic Wastes

1. LISTED WASTES

a) The F-list - (non-specific source wastes) identifies wastes from common manufacturing and industrial processes.

b) The K-list - (source-specific wastes). This list includes certain wastes from specific industries, such as petroleum refining or pesticide manufacturing

c) The P-list - and the U-list (discarded commercial chemical products). These lists include specific commercial chemical products in an unused form.

CHARACTERISTIC WASTES

a) Ignitability- can create fires under certain conditions, are spontaneously combustible, or have a flash point less than 60 °C (140 °F).

a) Corrosivity- capable of corroding metal containers, such as storage tanks, drums, and barrels.

b) Reactivity- unstable under "normal" conditions. They can cause explosions, toxic fumes, gases, or vapors when heated, compressed, or mixed with water.

a) Toxicity- harmful or fatal when ingested or absorbed. When toxic wastes are land disposed, contaminated liquid may leach from the waste and pollute ground water.

TOXIC WASTE

waste material that can cause death, injury or birth defects to living creatures. It spreads quite easily and can contaminate lakes, rivers, and the atmosphere
