What is a difference between detergent and sanitizer?
detergent remove dirt & risidue of products from surface of equipment while sanitizer kill almost microorganisms present on surface. If you know more than please answer.............
Will radioactive fallout make the surface it comes into contact with radioactive?
Remember, radioactive fallout on a surface does not make the surface itself radioactive. The particles themselves are radioactive, not the surface they come in contact with. The surface can usually be cleaned of any contamination
What is the difference between a wetting and non-wetting fluid?
A wetting fluid is capable of maintaining surface contact with a solid and its contact angles are less than 90 degrees (the angle starts from the wetted surface to the surface of the fluid). However non-wetting fluids are not willing to keep the contact area as large as wetting fluids and their contact angles are higher than 90 degrees. Imagine a droplet of mercury. As a non-wetting fluid, mercury remains still on a solid surface like a ball. It does not spread on the solid surface like water.
Does the type of container affect the evaporation?
Evaporation only happens at the surface. So a wider container that allows for a greater surface to be in contact with air, the faster the evaporation.
Kid friendly definition of condensation?
Water that collects as droplets on a cold surface when humid air is in contact with it.
What type of hazard can result from using to little sanitizer solution or exposure time to the food contact surface?
Chemical
What is a QUAT based sanitizer?
A quat based hand sanitizer is a product that is based on Quaternary Ammonum Comounds (Quats). Benzithonium Chloride and Benzyalchonum Chloride are two common Quats. They are an effective hard surface sanitizer and have recently been emerging as an alternative ingredient to alcohol in the hand sanitizer market.

Do you have to wash hands after using hand sanitizer?
Not If you don't get your hand soiled with something dirty Normal contact with a patient or a dry surface with possible bacteria is not a problem
Why rough surface of a catalyst is more effective?
Rough surfaces form irregular surface increase the surface area. Catalytic action is directly proportional to the area of contact.
What is a difference between detergent and sanitizer?
detergent remove dirt & risidue of products from surface of equipment while sanitizer kill almost microorganisms present on surface. If you know more than please answer.............
What is contact angle in penetrant test?
The contact angle is the angle in which the liquid interface meets the solid surface. The contact angle should be as small as possible to have an effective penetrant material.
What are the basic step for cleaning and sanitizing?
Sanitizing is the process of reducing the number of microorganisms on a clean surface to safe levels. To be effective, cleaning and sanitizing must be a two-step process. Surfaces must first be cleaned and rinsed before being sanitized. (ServSafe Essentials section 11-21)
Is hand sanitizer good?
No, because even if it is 99% effective in killing bacteria, the 1% is could leave up to 1000 bacteria that can cause sickness. Soap and water is most effective in eliminating bacteria from the skin's surface (eliminate in this case does not mean kill; instead it means to wash off)
Explain what is meant by a food contact surface?
Surface that touch food are called "food contact surfaces".
What do you do to make sure the strength of a sanitizer is the correct strength to use on a food prep surface?
always follow manufactures instructions on how to use the sanitizer especially the dilution instructions; if unsure ask someone to do it with you.
Are hand sanitizers and antibacterial wipes equally effective?
As long as the products contain the right amount of antibacterial and antimicrobial agents, it does not matter how effective it is. How you use a particular product is important. Wipes are useful, when you wiping down a dirty surface. But alcohol hand sanitizer is used when you have touched any dirty and contaminated article or object.
