Give the two classification of cleaning tools and equipment and their examples brainly

Maintaining a regular cleaning and sanitizing schedule is integral to preventing cross-contamination and food-borne illness. There are four main types of cleaning agents used in commercial kitchens:

  1. Detergents
  2. Degreasers
  3. Abrasives
  4. Acids

For effective cleaning, be sure to use the correct cleaning agent for the type of item to be cleaned, the cleaning method you’ll be using and the type of soiling on the item. Learn about the four most common types of cleaning agents and when to use them.

1. Detergents

Detergents are the most common type of cleaning agent and are used in home and commercial kitchens. They work by breaking up dirt or soil, making it easy to wash it away.

The detergents used in commercial kitchens are usually synthetic detergents made from petroleum products and may be in the form of powder, liquid, gel or crystals.

2. Degreasers

Degreasers are sometimes known as solvent cleaners and are used to remove grease from surfaces such as oven tops, counters and grill backsplashes.

Methylated spirits or white spirit were commonly used as degreasers in the past. Most food businesses now try to use non-toxic, non-fuming degreasers in their operations to prevent chemical contamination.

3. Abrasives

Abrasives are substances or chemicals that depend on rubbing or scrubbing action to clean dirt from hard surfaces. In commercial kitchens, abrasives are usually used to clean floors, pots and pans.

Abrasives should be used with care as they may scratch certain types of materials used for kitchen equipment such as plastic or stainless steel.

4. Acids

Acid cleaners are the most powerful type of cleaning agent and should be used with care. If they are not diluted correctly, acid cleaners can be very poisonous and corrosive.

Acid cleaners are generally used to remove mineral deposits and are useful for descaling dishwashers or removing rust from restroom facilities.

Properly handling cleaning agents

Remember that exposure to chemicals used in cleaning agents can lead to skin irritations, chemical poisoning, respiratory problems and, in extreme cases, even death. In a food business, all employees should be properly trained in understanding chemical hazards, how to handle products safely and what personal protective equipment should be worn when handling the product. Best practices for handling cleaning agents include:

  • storing chemicals in a secure place in their sealed original containers, well away from food or any equipment may come into contact with food
  • wearing personal protective equipment required to be worn when handling the product, such as gloves or safety glasses
  • following the manufacturer’s instructions when using the product or disposing of the product
  • cleaning and sanitising cleaning equipment such as brushes, mops and other janitorial tools after use and storing them in a well maintained, dry, locked area
  • using different cloths for wiping and cleaning, and replacing them regularly

Always follow cleaning with sanitizing

Cleaning is only the first step to a germ-free kitchen. Cleaning is done using detergent, but it doesn’t kill bacteria or other microorganisms that can cause food poisoning. To kill bacteria and ensure a clean workplace, you must follow cleaning with sanitizing.

Effective cleaning and sanitizing also helps to:

  • prevent pests from entering your business
  • prevent cross-contamination
  • prevent allergic reactions caused by cross-contamination

Make sure everyone who handles food in your business knows how to clean and sanitize properly and why it's important. Keep a regular kitchen equipment cleaning schedule to keep track of daily, weekly and monthly tasks. Enrolling your staff in a food handling course can help to ensure that your business stays compliant with food safety laws and regulations, passes health inspections and protects customers from health risks like allergic reactions and food poisoning.

The Canadian Institute of Food Safety (CIFS) provides online food safety courses that are approved in every province and territory in Canada. For more information about our Food Handler Certification Course, contact us or view our food handling certificate course page.

Did you know that an estimated 1 in 6 Americans will get sick from food poisoning this year alone? Food poisoning not only sends 128,000 Americans to the hospital each year—it can also cause long-term health problems. You can help keep your family safe from food poisoning at home by following these four simple steps: clean, separate, cook and, chill.

Clean: Wash Hands, Utensils, and Surfaces Often

Germs that can make you sick can survive in many places around your kitchen, including your food, hands, utensils, cutting boards, and countertops.

Wash your hands the right way:

  • Use plain soap and water—skip the antibacterial soap—and scrub the backs of your hands, between your fingers, and under your nails for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
  • Rinse hands, then dry with a clean towel.
  • Wash your hands often, especially during these key times when germs can spread:
    • Beforeduring, and after preparing food
    • After handling raw meat, poultry, seafood, or their juices, or uncooked eggs
    • Before eating
    • After using the toilet
    • After changing diapers or cleaning up a child who has used the toilet
    • After touching an animal, animal feed, or animal waste
    • After touching garbage
    • Before and after caring for someone who is sick
    • Before and after treating a cut or wound
    • After blowing your nose, coughing, or sneezing
    • After handling pet food or pet treats.

Wash surfaces and utensils after each use:

  • Wash cutting boards, dishes, utensils, and countertops with hot, soapy water, especially after they’ve held raw meat, poultry, seafood, or eggs.
  • Wash dish cloths often in the hot cycle of your washing machine.

Wash fruits and vegetables, but not meat, poultry, or eggs:

  • Rinse fruits and vegetables under running water without soap, bleach, or commercial produce washes.
  • Rinse fruits and vegetables before peeling, removing skin, or cutting away any damaged or bruised areas.
  • Scrub firm produce like melons or cucumbers with a clean produce brush.
  • Dry produce with a paper towel or clean cloth towel.
  • Don’t wash meat, poultry, eggs, or seafood to avoid spreading harmful germs around your kitchen.
  • Produce labeled as “pre-washed” does not need to be washed again.

Separate: Don’t Cross Contaminate

Use separate cutting boards and plates for produce, meat, poultry, seafood, and eggs:

  • Use one cutting board for fresh produce or other foods that won’t be cooked before they’re eaten, and another for raw meat, poultry, or seafood. Replace them when they are worn.
  • Use separate plates and utensils for cooked and raw foods.
  • Use hot, soapy water to thoroughly wash plates, utensils, and cutting boards that touched raw meat, poultry, seafood, eggs, or flour.

Keep certain types of food separate:

  • In your shopping cart, separate raw meat, poultry, seafood, and eggs from other foods and place packages of raw meat, poultry, and seafood in plastic bags if available. When you check out, place raw meat, poultry, and seafood in separate bags from other foods. 
  • At home, place raw meat, poultry, and seafood in containers or sealed, leakproof plastic bags. Freeze them if you’re not planning to use them within a few days.
  • In the fridge, keep eggs in their original carton and store them in the main compartment—not in the door.

Cook to the Right Temperature

Food is safely cooked when the internal temperature is high enough to kill germs that can make you sick:

  • Use a food thermometer to be sure your food is safe. When you think your food is done, place the food thermometer in the thickest part of the food, making sure not to touch bone, fat, or gristle.
  • Refer to our Minimum Cooking Temperatures Chart to be sure your foods have reached a safe temperature.

Keep food hot (140˚F or above) after cooking:

If you’re not serving food right after cooking, keep it out of the temperature danger zone (between 40°F -140°F) where germs grow rapidly by using a heat source like a chafing dish, warming tray, or slow cooker.

Microwave food thoroughly (165˚F or above):

  • Read package directions for cooking and follow them exactly to make sure food is thoroughly cooked.
  • If the food label says, “Let stand for x minutes after cooking,” follow the directions — letting microwaved food sit for a few minutes allows food to cook thoroughly as colder areas absorb heat from hotter areas.
  • Stir food in the middle of heating. Follow package directions for commercially prepared frozen food; some are not designed to be stirred while heating.

Follow special guidelines for barbeques and smokers:

Chill: Refrigerate and Freeze Food Properly

Refrigerate perishable foods within 2 hours:

  • Bacteria that cause food poisoning multiply quickest between 40°F and 140°F.
  • Your refrigerator should be set to 40°F or below and your freezer to 0°F or below. Use an appliance thermometer to be sure.
  • Never leave perishable foods out of refrigeration for more than 2 hours. If the food is exposed to temperatures above 90°F (like a hot car or summer picnic), refrigerate it within 1 hour.
  • Leftovers should be placed in shallow containers and refrigerated promptly to allow quick cooling.
  • Never thaw or marinate foods on the counter. The safest way to thaw or marinate meat, poultry, and seafood is in the refrigerator.
  • Freezing does not destroy harmful germs, but it does keep food safe until you can cook it.
  • Know when to throw out food by checking our Safe Storage Times chart. Be sure you throw food out before harmful bacteria grow.
