How to Apply Safety Rules and Techniques for the Chemistry Laboratory This exercise explores some basic safety and first aid rules and the reason for their existence. In addition, you will also devise some techniques for doing some experiments. Use complete sentences to answer the questions below. PART A 1. Describe some clothing and accessories that would be inappropriate in the lab. Explain why they should NOT be worn. 2. Are there any other things associated with you person that might be a safety hazard in the lab? 3. Explain the location and the use of each with respect to the chem. lab: a. Fire extinquisher b. Fire blanket c. Phone d. Eyewash e. Shower 4. Explain what should be done if someone happens to: a. Receive a burn b. Receive a cut c. Pour acid or base on their body or clothing d.
