These hazards impact emergency responders and effected communities. In some cases, hazardous substances may irritate the skin or eyes, make it difficult to breathe, cause headaches and nausea, or result in other types of illness.
Poor waste management contributes to climate change and air pollution, and directly affects many ecosystems and species. Landfills, considered the last resort in the waste hierarchy, release methane, a very powerful greenhouse gas linked to climate change.
Class 1: Explosives. Class 2: Gases. Class 3: Flammable Liquids. Class 4: Flammable Solids or Substances.
Types of Environmental Hazards We face countless environmental hazards every day. To better understand them, we can think of them as falling into four categories: physical, chemical, biological, and cultural.
Industrial waste is defined as waste generated by manufacturing or industrial processes. The types of industrial waste generated include cafeteria garbage, dirt and gravel, masonry and concrete, scrap metals, trash, oil, solvents, chemicals, weed grass and trees, wood and scrap lumber, and similar wastes.
EPA's regulations in the Code of Federal Regulations (40 CFR) define four hazardous waste characteristic properties: ignitability, corrosivity, reactivity, or toxicity (see 40 CFR 261.21- 261.24).
P- and U-listed wastes are “unused commercial chemicals” that are being disposed of, such as expired or spilled chemicals that were then cleaned up. The main difference between P- and U-Listed wastes is their level of risk. U-listed wastes are considered “toxic” but not as toxic as P-listed wastes.
Many hazardous wastes create an immediate health hazard to anyone who may come into contact with them. This can be a chemical byproduct or a contaminated solid, or anything in between. For this reason, proper and swift disposal is a must.
To us hazardous waste is a valuable resource that can be turned into something new and useful. Recycling hazardous waste is good for the environment, but it can also lead to increased competitive advantages for businesses and industries.
Solid chemical waste is disposed via trash disposal or the Chemical Waste Program. Solids are never disposed down the drain or in storm drains.
