Hazmat & Radiation

Hazardous substances pose a risk to both lab and other personnel who may contact the chemicals or animals during:

  • Preparation activities
  • Animal dosing
  • Husbandry activities
    • Cleaning cages
    • Changing and disposing of bedding

To protect the broad range of individuals with potential exposure, all hazardous substances must be identified in all relevant locations where animal research is conducted including:

  • Research labs
  • Animal housing
  • Cage wash
  • Locations where chemicals may be:
    • Stored
    • Prepared
    • Used (i.e. procedure rooms)
Waste Disposal and Collection

The Hazardous Waste Web page provides procedures for preparing biohazardous and radiological waste for disposal or collection.

Biological Exposure Risks

Biological substances posing a risk to personnel include:

Biological Substances Definition
Pathogenic Agent Any material known to harbor organisms or agents capable of infecting human or animal hosts or causing environmental harm if released.
Human Source Material An agent known to be transmissible through contact with human blood, blood products, body fluids, tissue or cells.
Recombinant DNA Nucleic acid molecules formed by laboratory methods, to bring together genetic material from multiple sources, creating sequences that would not otherwise be found in the biological organism.
Select Agents Any substance (viruses, bacterial, and toxins), with the potential of being used as bioweapons or posing significant risk to agriculture or public health.

Chemical Exposure Risks

Chemical material, posing a risk to personnel, based on the following hazard classifications:

Radiation Exposure Risks

Occupational radiation exposure includes:

  • External exposure to ionizing radiation emitted by radioactive materials
  • External exposure from devices that produce x-rays or other forms of ionizing radiation (such as electrons or protons)
  • Internal exposure from inhaled, ingested, or absorbed radioactive materials

Color-Coded Cage Cards

To ensure the safe handling of animals containing radioactive material, color-coded cage cards are used to indicate the standardized protocol for animal care. The color-coded cards indicate to animal care takers coming in contact with caged animals as to the level of hazard they might encounter.  In order of increasing radiological risk, the color code used are as follows:

COLOR… REPRESENTS TO THE CARETAKERS…
Green The amount of radioactive material excreted is minimal and all waste and bedding can be treated as non-radioactive material.
Yellow That caution should be used because the animal and all waste and bedding are radioactive.
Red Not to proceed until they have contacted their ULAM Area Supervisor for further instruction.
