HAZMAT Class 7 Radioactive substances

HAZMAT Class 7 Radioactive substances are materials that emit radiation. This class of Hazardous Materials is regulated by the United States Department of Transportation (DOT) and the International Atomic Energy Agency (IAEA) due to their potential to cause harm to people, property, and the environment.

Definition

HAZMAT Class 7 Radioactive substances are defined as any material containing radionuclides where both the activity concentration and the total activity in the consignment exceed the values specified in the IAEA Regulations for the Safe Transport of Radioactive Material. These substances can be naturally occurring or artificially produced.

Classification

The DOT and IAEA classify HAZMAT Class 7 Radioactive substances into seven categories based on their level of radioactivity and potential harm:

1. Category I-WHITE
2. Category II-YELLOW
3. Category III-YELLOW
4. Category IV-RED
5. Category V-GREEN
6. Category VI-BLUE
7. Category VII-PURPLE

Each category has specific packaging, labeling, and transportation requirements to ensure the safe handling and transport of these materials.

Packaging and Transport

The packaging and transport of HAZMAT Class 7 Radioactive substances are strictly regulated. The packaging must be designed to protect the contents from damage during normal transportation and handling. The transport of these substances must follow specific routes and schedules to minimize the risk of exposure to the public and the environment.

Safety Measures

Safety measures for handling and transporting HAZMAT Class 7 Radioactive substances include the use of protective clothing, radiation detection devices, and proper training. These measures are designed to protect workers and the public from exposure to radiation.
