Identifying hazardous substances For each hazardous substance sign in this table, describe the type of hazard substance and give an example of a material to which it might be applicable. Hazardous substance sign XX Harmful Irritant F+ Type of hazard substance Example of material

Create a list of 5-10 common chemicals or hazardous materials used in a kitchen/restaurant environment and explain the potential effects that can be caused by each. Identify the improper handling techniques that could cause these potential effects

What chemicals do you think are most harmful to your own health? How are you exposed? How could you go about determining whether or not each of these chemicals was harmful to you?

Identifying warning signs and labels For each warning sign in this table, describe the type of hazard and give an example of a material to which it might be applicable. Warning sign Type of hazard Example of material

What is the difference between single use, limited use and reusable chemical protective garments?

Like anatomy and physiology, chemistry may be a somewhat scary subject for you. Think of it this way: Chemistry is simply the study of matter, its composition, structure, properties, and the changes matter may undergo. Your goal in training as a cosmetologist is not to become a scientist, but to develop a comfort level with the basics and an ability to discuss chemistry in relation to your profession. This will increase your credibility significantly with your clients, especially during the consultation process. In the space provided, write how chemistry affects your everyday life.

What is the purpose of Safety Data Sheets? Why are these important when handling common food service chemicals? What information/components are generally included? How do Safety Data Sheets vary?

Identify basic procedures for dealing with laboratory accidents.

A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of carbon tetrachloride, diethylamine, pentane, acetone, and tetrahydrofuran. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density - 3 1.6 g·cm carbon tetrachloride diethylamine - 3 0.71 g·cm pentane 3 0.63 g cm 3 0.79 g cm acetone tetrahydrofuran - 3 0.89 g cm Next, the chemist measures the volume of the unknown liquid as 1.427 L and the mass of the unknown liquid as 894. g. Calculate the density of the liquid. Round 3 your answer to 3 significant digits. |lg.cm Given the data above, is it possible to identify the liquid? yes no carbon tetrachloride diethylamine If it is possible to identify the liquid, do so. pentane acetone tetrahydrofuran
