CHEM120 Week 1 Virtual Lab: Chemistry Safety Part I and Part II OL Lab 1: Chemistry Safety Learning Outcomes • Create biodiesel from algal oil • Identify the hazards posed by chem... icals and how to handle them • React quickly and save lives in case of a fire emergency • Use the CAS numbers to plan your experiment • Identify how to dispose of halogenated and non-halogenated waste • Identify H and P phrases in the safety data sheet • Safely use a chemical fume hood Introduction Are you ready to work in a chemistry lab? In the Chemistry Safety simulation you will learn how to safely work with organic solvents. Experiment with dangerous chemicals and make mistakes without putting yourself in danger. Biodiesel for a greener world We need to find sustainable fuel sources to reduce CO2 emissions and battle climate change. Your mission in the Chemistry Safety lab is therefore to find an effective process for producing biodiesel from algal oils. Can you figure out how to convert oil into diesel? Fumes in the fume hood In the Chemistry Safety lab, you’ll get to work with methanol, a volatile organic solvent. This means you need to work in a chemical fume hood. Learn how to set up your reaction in the fume hood and dispose solvents in the organic waste. Look up the physical properties of your reactants in the safety data sheet, to make sure your reaction will be successful. Dangers in the lab In the Chemistry Safety lab, you’ll learn to identify the hazards posed by the different chemicals that you are using, which is a very important step in the planning of every experiment. Part 1: Complete Labster Lab Chemistry Safety Complete all parts of the Chemistry Safety Virtual Simulation Lab. Part 2: Report and Reflection Purpose: Describe in complete sentences and in your own words, the purpose of this simulation. The purpose of this simulation to equip us on how to mix chemicals, lab safety practices, and the dangers of some chemicals. Observations: Record three observations from the simulation that would help you perform experiments safely in a lab. 1. Put on appropriate personal protective equipment, such as lab coat, google and gloves. 2. Decontaminate all potentially infectious materials before disposal. 3. Decontaminate all work surfaces before and after your experiments. Answer the questions below: 1. Look up an MSDS of the chemical HCl. What are the major hazards and what precautions would you take when handling this chemical? Considering the corrosiveness of HCI, it is required to wear a chemical-resistant apron, chemical-resistant gloves and chemical splash goggles at all times when handling, to protect your eyes and skin. 2. Why is proper waste disposal important in a lab setting? Proper waste disposal is critical due to the fact that certain types of wastes can be hazardous and can contaminate the environment if not handled properly. 3. Why is the proper usage of personal protective equipment (PPE) key to a safe lab experience? PPE is almost always necessary to protect workers from chemical exposures and other hazards. For example, Eye and face protection is extremely important when working in a lab and must be worn if hazards exist that could cause eye or face injury. [Show More]
