What document should you refer to if you have questions regarding the safety or disposal of a chemical where can this document be located?

You can refer to Material Safety Data Sheets (MSDS) if you have any questions regarding the safety.

Why are there increasing levels of biological containment procedures?

There is an increasing levels of biological contaminant procedures because they are necessary in preventing spores from becoming as dormant and that they are also responsible for preventing bacterial infections and as well as resistance of viruses.

What constitutes personal protective equipment when Should personal protective equipment be worn Why is personal protective equipment important?

Personal protective equipment, commonly referred to as “PPE”, is equipment worn to minimize exposure to hazards that cause serious workplace injuries and illnesses. These injuries and illnesses may result from contact with chemical, radiological, physical, electrical, mechanical, or other workplace hazards.

What safety issues are important in mind when working with microorganisms?

Never eat or drink in the laboratory while working with microorganisms. Keep your fingers out of your mouth, and wash your hands before and after the laboratory activity. Cover any cuts on your hands with a bandage. Gloves may be worn as extra protection.

What are 5 safety factors to consider when working with bacteria?

Microorganisms Safety Guide

  • Treat all microorganisms as potential pathogens.
  • Sterilize equipment and materials.
  • Disinfect work areas before and after use.
  • Wash your hands.
  • Never pipette by mouth.
  • Do not eat or drink in the lab, nor store food in areas where microorganisms are stored.
  • Label everything clearly.

What are two examples of beneficial bacteria?

Some examples of helpful bacteria include E. Coli (when used for the digestion process), Streptomyces, and Rhizobium. Some examples of harmful bacteria include E. Coli (when contaminating food), Listeriosis, and Salmonella.

What are examples of beneficial bacteria?

Types of Probiotics and What They Do

  • Lactobacillus. In the body, lactobacillus bacteria are normally found in the digestive, urinary, and genital systems.
  • Bifidobacteria. Bifidobacteria make up most of the “good” bacteria living in the gut.
  • Streptococcus thermophilus.
  • Saccharomyces boulardii.

What are five major categories of microorganisms How can you distinguish between them?

There are 5 basic groups of microorganisms:

  • a. Bacteria. Bacteria are typically unicellular, microscopic, prokaryotic organisms that reproduce by binary fission (see Fig.
  • b. Fungi: yeasts and molds.
  • c. Viruses.
  • d. Protozoa.
  • e. Algae.

What is the difference between bacteria and protozoa?

Protozoa (pro-toe-ZO-uh) are one-celled organisms, like bacteria. But they are bigger than bacteria and contain a nucleus and other cell structures, making them more like plant and animal cells. Protozoa love moisture.

Which is the biggest bacteria fungi or viruses?

Bacteria are bigger and more complex than viruses, though they can still spread through the air. A bacterium is a single cell, and it can live and reproduce almost anywhere on its own: in soil, in water and in our bodies.

What is the difference between fungus and mold?

Fungi can exist as unicellular microscopic organisms called yeasts, as multicellular microscopic molds with hyphae, or as macroscopic mushrooms with a visible sexual organ, the fruiting body. Molds, on the other hand, are multicellular microscopic fungi, typically characterized by the presence of hyphae filaments.

How do you get rid of fungus in your home?

Sprinkle baking soda onto a mouldy patch or spray a solution of 1 teaspoon of baking soda and 2 cups of hot water directly on the mould. Let it sit for an hour before scrubbing with a brush and rinsing off the residue. Give the area final spray of vinegar to disinfect it and prevent regrowth. Wipe dry.
