Nitrile rubber gloves

Transfer the gel in a UV chamber carefully (as ethidium bromide is carcinogen, use two pairs of nitrile rubber gloves and be careful to prevent any contamination deposit the buffer containing ethidium bromide in a special waste bottle). 

Shut off all possible sources of ignition. Wear nitrile rubber gloves, laboratory coat, and eye protection. A self-contained breathing apparatus may be necessary, depending on the size of the spill. Cover the spill with a 1 1 1 mixture by weight of sodium carbonate or calcium carbonate, clay cat litter (bentonite), and sand. When the acetic anhydride has been absorbed, scoop into a plastic pail and, in the fume hood, very slowly add the mixture to a pail of cold water. Allow it to stand for 24 hours. Test pH of the solution and neutralize if necessary with sodium carbonate. Decant the solution to the drain with water. Treat the solid residue as normal refuse. The spillage site should be washed thoroughly with soap and water.19-22... 

Small Quantities. Wear nitrile rubber gloves, laboratory coat, and eye protection. Work in the fume hood. To decompose 5 mL (5.4 g) of acetic anhydride, place 60 mL of a 2.5 M sodium hydroxide solution (prepared by dissolving 6.0 g of NaOH in 60 mL of water) in a 250-mL, three-necked, round-bottom flask equipped with a stirrer, dropping funnel, and thermometer. Add the acetic anhydride to the dropping funnel and run it dropwise into stirred solution at such a rate that the temperature does not rise above 35°C. Allow to stir at room temperature overnight. Neutralize solution to pH 7 with 2 M hydrochloric acid (slowly add 16 mL of concentrated acid to 80 mL of cold water) and pour into the drain.23... 

Small Quantities. Wear nitrile rubber gloves, laboratory coat, and eye protection. Work in the fume hood. To decompose 10 mL (16.6 g) of acetyl bromide, place 160 mL... 

Shut off all possible sources of ignition. Instruct others to keep a safe distance. Wear breathing apparatus, eye protection, laboratory coat, and nitrile rubber gloves. Cover the spill with a 1 1 1 mixture by weight of sodium carbonate or calcium carbonate, clay cat... 

Small Quantities. Work in the fume hood. Wear eye protection, nitrile rubber gloves and laboratory coat. Place 6.0 g (7 mL, 0.107 mol) of acrolein in a 1 L, three-necked, round-bottom flask equipped with a thermometer, stirrer, and dropping funnel. Over a period of 10 minutes, add 50 mL of a solution of 63 g (0.4 mol) of potassium permanganate in 700 mL of water. If the purple color is not discharged, warm the mixture on steam bath until it becomes brown. Add the remainder of the permanganate solution at such a rate that the temperature does not exceed 45°C. When addition is complete, heat the mixture on the steam bath to 70-80°C, while stirring, for 1 hour. Cool the mixture to room temperature, and acidify to pH 1 with 3 M sulfuric acid (16 mL of concentrated acid cautiously added to 84 mL of cold water). Add solid sodium bisulfite, while stirring, until a colorless solution is produced. Wash the solution into the drain with water.7... 

Small Quantities. Wear nitrile rubber gloves, laboratory coat, and eye protection. Work in the fume hood. Dissolve the acrylic acid in water to give a 10% solution. For each 5 mL of this solution, add 250 mL of 2% aqueous sodium hydroxide and, while stirring, 10 g of potassium permanganate. Stir at room temperature for 48 hours. Add solid sodium bisulfite until the solution is colorless, neutralize with 5% hydrochloric acid, and pour the liquid into the drain. Discard any small amount of brown solid (manganese dioxide) with regular refuse.7... 

Small Quantities. Wear nitrile rubber gloves, eye protection, all-purpose or special canister respirator for ammonia, and laboratory coat. Pour into a large container of water and neutralize with 5% hydrochloric acid. Pour into the drain.6... 

Wear nitrile rubber gloves, laboratory coat, and goggles. Scoop the solid into a pail of water. Slowly add dry sodium carbonate to pH 7. The solution can be poured into the drain. The site of spillage should be washed thoroughly to remove all of the ammonium nitrate which may render organic matter (e.g., wood) dangerously explosive.32,33... 

Wear nitrile rubber gloves, eye protection, and laboratory coat. Avoid breathing dust. In the fume hood, dissolve the arsenic compound in acidified boiling water (for 1 g of arsenic compound, use 100 mL of water containing 6 drops of concentrated hydrochloric acid). Add a solution of thioacetamide (for each 1 g of arsenic salt, use 0.2 g of thioacetamide in 20 mL of water). Boil the mixture for 20 minutes and then basify with 2 M sodium hydroxide (prepared by dissolving 8 g of NaOH in 100 mL of water). Filter the precipitate, dry, and package for disposal in a secure landfill site. ... 

Small Quantities. Wear nitrile rubber gloves, laboratory coat, and eye protection. Avoid breathing dust. Dissolve the barium salt in the minimum volume of water. For each gram of barium salt, add 15 mL of 10% sodium sulfate solution. Let stand for 1 week. Test for completeness of precipitation by adding a few drops of 10% sodium sulfate solution. If required, add more sodium sulfate solution until no further precipitation occurs. Decant supernatant liquid or filter solid. Treat solid as normal refuse. Wash liquid into drain.20...
