Disinfectant means any oxidant, including but not limited to chlorine, chlorine dioxide, chloramines, and ozone added to water in any part of the treatment or distribution process, that is intended to kill or inactivate pathogenic microorganisms.
Disinfect means to eliminate virtually all germs from inanimate surfaces through the use of chemicals or physical agents (e.g., heat). In the child care environment, a solution of ¼ cup household liquid chlorine bleach added to one gallon of water (or one tablespoon bleach to one quart of water) and prepared fresh daily is an effective disinfectant for environmental surfaces and other objects. A weaker solution of 1 tablespoon bleach to 1 gallon of cool water is effective for use on toys, eating utensils, etc. Commercial products may also be used.
Disinfection means a process which inactivates pathogenic organisms in water by chemical oxidants or equivalent agents.
Residual disinfectant concentration (“C” in CT cal- culations) means the concentration of disinfectant measured in mg/l in a representative sample of water.
Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
