2. Visible Light
3. Sound Waves
4. Magnetic Fields
✔✔What are some significant impacts of Non-Ionizing Radiation? - ✔✔1. Ultraviolet
radiation exposure causes sunburn
2. Causes genetic damage to skin cells and result in skin cancer
3. Beyond the control of hazardous materials/WMD responders
✔✔What is Specific Gravity? - ✔✔Ratio of the weight of a liquid or solid as compared to
an equal amount of water.
✔✔What is the Specific Gravity of Water? - ✔✔1.0
✔✔What are some problems with Toxic Products of Combustion? - ✔✔1. Combustion
may alter the original products
, 2. Smoke, steam, and runoff from fire and firefighting operations may contaminate a
larger area
✔✔What is Vapor Density? - ✔✔Ratio of the weight of a vapor as compared to air
✔✔What is the Vapor Density of Air? - ✔✔1.0
✔✔What is Vapor Pressure? - ✔✔The pressure at any given temperature at which the
vapor and liquid phases of the substance are in equilibrium in a closed container.
✔✔What is water Solubility? - ✔✔The ability of a material to blend uniformly (solubility)
with another
✔✔What are some types of Solubility? - ✔✔1. Solid in Liquid
2. Liquid in Liquid
3. Gas in Liquid
4. Gas in Gas
✔✔What can Solubility also referred to as? - ✔✔Miscible
✔✔What is Polymerization? - ✔✔Chemical reactions in which two or more molecules
chemically combine to form larger molecules
✔✔What is Expansion Ratio? - ✔✔Volume of a substance in liquid form compared to
the volume of the same number of molecules of that substance is gas form
✔✔What are Biological Agents? - ✔✔Viruses, bacteria, or their toxins which are harmful
to people, animals or crops
✔✔What is a Biological Toxin? - ✔✔Poison produced by living organisms.
✔✔What is Contamination? - ✔✔The transfer of a hazardous material to persons,
equipment, and the environment in greater than acceptable quantities
✔✔What is Secondary Contamination? - ✔✔The indirect transfer when contaminated
personnel or equipment carries a contaminant away from the hot zone and transfers it
to another person
✔✔What is Exposure? - ✔✔People exposed to a hazardous material but not
necessarily always contaminated by it
✔✔What is a Hazard? - ✔✔Something capable of posing an unreasonable risk to health
and safety
