Hazardous materials:

Hazardous materials:

Introduction:

Hazardous materials (hazmat) are any material that has properties that may result in risk or injury to health and/or destruction of life or facilities. Many hazardous materials (hazmat) do not have a taste or an odor. Some can be detected because they cause physical reactions such as watering eyes or nausea. Some Hazardous Materials exist beneath the surface of the ground and have an oil or foam-like appearance. The substance can be identified from placards, labels or markings on the transporters.

Hazardous Material can be: ·

Corrosive Hazmat Materials:
are strong enough to eat away at steel drums or human skin. Because they can eat through the containers they are carried in, they are of special concern during transportation. Example: car battery acids ·
Ignitable Hazmat Materials:
present a fire hazard because they are flammable at relatively low temperatures. This causes a risk of explosion and the spreading of toxic gas over an area, as well as fire and smoke. Examples: paint removers, the chemical Benzene ·
Reactive Materials:
can explode or release deadly fumes by mixing with water or reacting to heat or pressure. Examples: old weapons and ammunition, sodium metal, stannic chloride ·
Radioactive Materials:
include materials with both high and low radioactivity that can lead to dangerous side effects for thousands of years. Most of these materials are produced at nuclear power plants and by research facilities. ·
Toxic Hazardous Materials:
consist of poisonous chemicals. People and animals exposed to these types of materials can develop severe health problems. Examples: lead, arsenic, mercury ·
Infectious Materials:
These materials are also toxic wastes, but are in a separate category. They consist of materials infected with some type of germ, bacteria, or virus that could cause disease in humans or animals. These types of materials often come from hospitals. Examples: hypodermic needles, human and animal waste.

Classification of Hazardous Materials:

The DOT has broad authority to regulate hazardous materials that are in transport, including the discretion to determine which materials shall be classified as "hazardous". These materials are placed in one of nine categories, based on their chemical and physical properties. Based on the classification of the material, the DOT is also responsible for determining the appropriate packaging materials for shipping or transport. Finally, also based on the material classification, strict guidelines are furnished for proper labeling/marking of packages of hazardous materials offered for transport, and for placarding of transport vehicles.
