LESSON 2.2!

Laboratory Clean-up and Sanitation: Why is it imp0rtant ?

PREVENTIONS LIST

To prevent fires and burns:


1. Use salt or baking soda, not water, to put out a grease fire.

2. Keep flammable materials away from the top of the range and away from portable appliances that produce heat.

3. Use a dry potholder to remove pans from the range.

4.Store flammable substances such as aerosol sprays away from heat sources.

5. Use a metal trashcan when disposing of hot or smoldering items.

6. Keep the range exhaust hood and ducts clean.

To prevent falls :

1. Wipe up all spills at once.

2. To reach items stored in high places, use a sturdy step stool or ladder.

3. Close cabinet doors and drawers.


To prevent cuts :

1. Keep sharp knives sharp. They are less likely to cause an accident than dull ones.

2. Use a cutting board.

3. Cut away from you with the knife blade slanted.

4. For peeling vegetables such as carrots or potatoes, use a peeler instead of a knife.

5. If a knife, kitchen scissors, or ice pick starts to fall, get out of the way. Do not try to catch it in mid-air.

6. Wash, dry and store knives separately from other dishes and utensils.

7. Keep your fingers away from beaters and blades in appliances.

8. Use knives and other sharp tools only for their intended purpose.

9. Sweep up broken glass immediately.

10. Wrap your hand in a towel to pick up broken glass.

11. When opening cans, cut the lids completely off.

12. Don’t leave sharp knives in a sink full of water.

To prevent electric shock :

1. Read appliance booklets before using appliances.

2. Keep electrical cords away from water and hot objects.

3. Do not plug several cords into an electrical outlet at one time.

4. Unplug portable appliances after you have used them.

5. Disconnect appliances before cleaning them. Do not put them in water unless the appliance is labeled “immersible.”

6. Before using an appliance, make sure your hands are dry and that you are standing on a dry surface.

7. Plug the cord of portable appliances into the appliances first, then into the wall.


To prevent microwave accidents:

1. Never use a microwave if the door appears damaged.

2. Never turn on the microwave if there is no food inside.

3. Do not heat sealed jars, cans, or bottles in the microwave.

4. Do not heat home-canned foods in a microwave. Use a conventional range.

5. Use potholders to remove food containers from the microwave.

6. Remove lids and plastic wrap carefully to avoid steam burns.

7. Distribute the heat by stirring microwaved foods before serving them.

5s - is a workplace organization method that uses a list of five Japanese words: seiri, seiton, seisĹŤ, seiketsu, and shitsuke. These have been translated as "Sort", "Set In order", "Shine", "Standardize" and "Sustain".

Seiri (Sort) – clearly separating necessary from unnecessary, and remove unnecessary.

Seiton (Set and Order) – visually arrange and identify items for ease of use and retrieval

Seisō (Shine) – keep the workplace clean (not pretty) to allow problems to be identified.

Seiketsu (Standardize) – continually monitor the level of clearing, organizing and cleaning.

Shitsuke (Sustain) – work towards a shared set of values regarding clearing, organizing and clean.

Food Safety, Sanitation, and Personal Hygiene

Workplace Sanitation

  • Maintaining a clean work environment is critical in preventing foodborne illness. Bacteria can grow on unsanitary surfaces and then contaminate food. Just because a work surface looks clean does not mean that it is sanitary. Always ensure that you clean and sanitize a work area before starting to prepare food.

Cleaning Procedures and Schedules

  • Cleaning with soap and other detergents is just one step of the cleaning procedure. It is also necessary to sanitize. Cleaning will remove any dirt or grease, but will not necessarily kill any bacteria or other pathogens. Only a sanitizer will kill bacteria and ensure the area is safe for food preparation.

  • A sanitation plan is important in any food service preparation area. It ensures that all surfaces are cleaned on a regular basis and reduces the risks of transferring bacteria or other pathogens from an unclean surface to clean equipment such as cutting boards or tools. A sanitation plan has two components:

  1. A list of cleaning and sanitizing agents or supplies with instructions on their safe use and storage

  2. A cleaning schedule, outlining how each item needs to be cleaned, who is responsible, and how frequently it happens



Routine Equipment Maintenance


  • All equipment must be routinely cleaned and inspected. Older equipment may have nooks and crannies where dirt and bacteria can hide, which can be difficult to clean effectively. Proper cleaning procedures must be established and followed at all times with regular review to ensure that procedures are working.

Importance of Personal Hygiene

  • It is imperative for safe food-handling outcomes for all workers to be familiar with standard sanitation and hygiene practices.

  • One of the basic principles is to break the cycle by avoiding cross-contamination, which can be achieved by ensuring personal hygiene practices are followed.


Proper personal hygiene is critical in any food service premise.

Personal hygiene includes:

  • Showering and bathing regularly

  • Keeping hair clean hair and covered or tied back

  • Keeping clean clothing and footwear that is used only at work

  • Handwashing regularly

  • Using clean utensils for tasting food

  • Using separate cloths for cleaning and wiping plates


Handwashing

Proper and regular handwashing is a critical part of any food safety system. You must always wash your hands after:

  • Sneezing, coughing, or touching your mouth or nose

  • Using the bathroom

  • Smoking or using toothpicks

  • Handling raw foods

  • Cleaning and wiping tables, food preparation surfaces, or equipment

  • Handling soiled objects, garbage, or money


The steps for proper handwashing are as follows:

  1. Wet hands with warm water.

  2. Apply liquid soap and lather for at least 20 to 30 seconds.

  3. Scrub backs of hands, wrists, all fingers, and under nails.

  4. Rinse under running water, pointing down toward the drain.

  5. Dry with a paper towel.

  6. Turn off taps and open the bathroom door using the paper towel.
