CH 324 QUANTIATITVE AND INSTRUMENTAL ANALYSIS SAFETY QUIZ – TEST 1 Safety in the Analytical Laboratory: Open Book Quiz, Test #1 Hung Nguyen - 934333226 1) If you are not doing any experimental work but are sitting at a lab bench doing calculations, why should you be wearing eye protection? -> Because other experiments are running and there is a chance things may go wrong and hurt me. 2) If your instructor is not wearing safety goggles, why should you? -> Because my instructor made the rules, so he is above the rule. Joke aside, I follow the safety rules, I will make sure my instructor following the rules too. 3) If you are told to mix 2 g of solid sodium peroxide with 20 mL of water, do you a) put the 2 g of sodium peroxide in a beaker and pour the water into it; or b) put the water in the beaker into the beaker and then add the sodium peroxide or c) does it matter? -> Water in first because it is liquid and if there is no chemical in it yet, the splashing will not be damaging. 4) The discoverer of nitrous oxide (N 2 O) found that breathing it produced a light-headed dizziness, and thus it became known as “laughing gas.” Which safety rules did he violate? -> No ventilation or gas mask was used 5) Ordinary household sugar is sometimes used as a chemical reagent. Why should a bottle of such sugar not be taken to a nearby area to sweeten coffee? -> because it was opened in a lab environment where contaminated with other chemicals. The instrument for chemistry experiments that was used to scoop the sugar out is usually not cleaned properly for food safety so I would rather not risking it. 6) If a reagent runs down the side of your glassware, why should you wash it off before continuing? -> I might forget about it later and accidentally touch the glassware with my bare hand and it will hurt. 7) Where is there an eyewash fountain? How is it used? -> In the same lab in certain areas.

CH 324 QUANTIATITVE AND INSTRUMENTAL ANALYSIS SAFETY QUIZ – TEST 1 11) What is an essential requirement of a laboratory notebook a) spiral binding, b) permanent binding c) numbered pages d) all pages unused? 12) When assembling or disassembling a burette, what should you use to help protect you from being cut if the burette breaks? -> Grasp the burette close to one end and gently squeeze the nose in 13) How do you dispose of acid and base waste? -> Neutralize first before dumping into designated container or the sink 14) Briefly describe the chemical accident in Bhopal India. -> The chemical accident in Bhopal, India, occurred on December 2-3, 1984, at a Union Carbide pesticide plant. It resulted from a toxic gas leak, mainly methyl isocyanate (MIC), due to safety issues and maintenance problems. The disaster exposed over half a million people to toxic fumes, causing thousands of immediate deaths and long-term health issues. It is one of the worst industrial accidents in history, with a death toll estimated between 15,000 and 20,000 people. The incident highlighted the importance of industrial safety and corporate responsibility. 15) What year did it happen? -> 1984 16) How many people died (immediately)? -> Not known 17) What is a reasonable estimate for how many totals deaths occurred in the first year after the accident? -> 8,000 to 10,000 18) Which is greater; the number of people killed at Bhopal or the number of people killed in all of the nuclear power accidents in the history of the nuclear industry? -> The total number of fatalities from all nuclear accidents combined is significantly less than the number of deaths in the Bhopal gas disaster. 19) Which is greater; the number of people killed in the 9/11 terrorist attacks or the number of people killed in the Bhopal accident? -> While both events were tragic and had significant loss of life, the 9/11 attacks had a higher death toll. 20) How does this relate to the course concept of “mastery of the material”? -> Know thyself and know the material.
