Chem 1-L General Chemistry Laboratory Manual Activity No.1 LABORATORY SAFETY AND PREVENTIVE MEASURES Name: Crisia Jane G. Lota Date Performed: 09 - 09 - 21 Section: BSN - 1K Date Submitted: 09 - 09 - 21 I. Objectives: With the aid of the power point presentation and video presented by the teacher, the chemistry students are expected to: 1. enumerate the importance of laboratory safety precautions, and 2. identify the different safety precautions. II. Instructions A. Read and answer the following questions. 1. What are the importance of Laboratory safety precautions? “% Laboratory safety precautions are necessary because caustic and toxic materials, volatile solvents, high- pressure gases, explosive compounds, and deadly bacteria can all be found in a laboratory. Laboratory disasters can be avoided with a little caution and following to safety requirements. 2. What are the first thing to do in the event of an accident in the laboratory? What about a fire? % Call the security hotline or activate the nearest fire alarm. To keep the fire contained, close the doors. Do not use the lift; instead, evacuate to a safe spot or depart the building via the stairway. Assist emergency responders with someone who is familiar with the incident and the laboratory. We have to do something. Maintain a calm and quiet demeanor while gathering information and assessing the issue. 3. A mercury thermometer breaks in the laboratory. What should be done? “% Put your gloves on. If there are any shards of glass or sharp items, pick them up carefully. All damaged items should be placed on a paper towel. Place the folded paper towel in a zip-lock bag. 4. How would you respond to a burning sensation of your hands after being in a laboratory? “% Remove the heat source with cool water or ice packs until the tissue around the burn feels normal. To avoid shock, the injured person should be covered. Call 911 and your campus's security office for immediate medical assistance. Chem 1-L General Chemistry Laboratory Manual 5. What is the purpose of each of the following? a. safety shower “ On-the-spot decontamination is provided through emergency showers and eyewash stations. They enable employees or students to flush away potentially harmful chemicals. Even with good engineering controls and safety safeguards, accidental chemical exposures can occur. b. fire blanket “* Small fires can be put out with fire blankets in the home, RV, boat, or garage. They can also be wrapped around someone whose clothing has caught fire. Fire blankets should be kept in or near a kitchen, but not too close to a possible hazard, such as above a stove. B. Analyze the picture carefully. Identify the different safety concerns shown in the picture below. Explain your answer. a) They are not wearing safety goggles, laboratory gown and gloves. b) The girl is not paying attention and almost spill or break that graduated cylinder. bo a) They did not keep their work area clean. b) They are eating inside the laboratory.
