Across
- 1. most commonly used sanitizers. They are effective against all bacteria and are fairly inexpensive.
- 4. Using heat to reduce the number of microorganisms on a clean surface to safe levels
- 5. licensed professionals who use safe, current methods to prevent and control pest control
- 8. Concentration: 12.5 to 25 ppm
- 10. The amount of sanitizer to water measured in parts per million. The concentration of sanitizer affects the effectiveness of the sanitizer solution
- 12. A kind of backflow that occurs whenever the pressure in the potable water supply drops below that of the contaminating water supply.
- 15. sheet supplied by the chemical manufacturer listing the chemical and it common names, potential physical and health hazards, information about using and handling it safely, and other important information.
- 16. Physical link in through which contaminants in drains, sewers and other wastewater sources can enter a drinkable water supply.
- 17. A significant threat or danger to health that requires immediate correction or closure to prevent injury.
- 18. Oragnization that develops and publishes standards for sanitary equipment design. It also assesses and certifies that equipment has met these standards.
- 19. group of sanitizers all having the same basic chemical structure. They work in most temperature and PH range , are non-corrosive and remain active for short periods of time after they have dried
Down
- 2. Devices installed above or alongside doors that blow a steady stream of air across am entryway, creating an air shield around open doors.
- 3. used in high temperature dish machines to prove they are reaching proper temperatures. They are irreversible. Like TTI thermometers
- 6. Federal agency that regulates and monitors workplace safety
- 7. fast-acting and effective against all bacteria. They are relatively nontoxic, and stable (they don’t separate). May stain porous surfaces and some plastics.
- 9. A space used to separate a water supply outlet from any potentially contaminated source
- 11. Unwanted reverse flow of contaminants through a cross-connection into a drinkable water system.
- 13. A figure expressing the acidity or alkalinity of a solution on a scale on which 7 is neutral, lower values are more acid, and higher values more alkaline.
- 14. (Bleach) Concentration: 50 to 100 ppm
