Laboratory coat

Caution Thallium compounds are highly toxic.3 However, they may he safely handled if prudent laboratory procedures are practiced. Rubber gloves and laboratory coats should be worn and reactions should be carried out in an efficient hood. In addition, thallium wastes should be collected and disposed of separately (Note 1). 

Detailed precautions for handling radioactive substances will be dictated by the nature and quantity of isotope and the likely level of exposure. Thus for some materials laboratory coats and gloves may be adequate for others a fully enclosed suit and respirator may be more appropriate. Some general precautions are listed in Table 10.6. 

Carothers claimed that he kept going only because he finally received one of Illinois few scholarships, 750 embellished with esteem. But he must also have persevered because he loved chemistry. As he admitted, even the smell of his laboratory coat, saturated with the inexpressibly pungent and complicated odors of lab no. 219 [filled him] with a nostalgia to return to the atmosphere of sweetly blended sulfur dioxide, bromine, chlorine, ammonia, hydrogen chloride, phosgene, chloroacetone, etc., etc., etc. ... 

Figure 3 shows a significant difference in thoron progeny activity plated-out on laboratory coat cotton cloth samples and Millipore filters (0.8 /un), and emery cloth. Differences between the two latter sample materials are not clear in these measurements. 

The clean laboratory for trace metals was divided into three areas entrance laboratory (with clothes changing annex), instrument laboratory, and ultraclean sample preparation laboratory, all under positive pressure with active charcoal filtered air. Personnel using the clean rooms were required to wear hair caps, polyethylene gloves, laboratory coats, and designated shoes. These items are worn only in the clean rooms. 

Ensure appropriate safety clothing is available usually, a laboratory coat and safety glasses are sufficient but certain methods will require additional equipment, such as gloves. 

Although it may appear cool to have the dirtiest and tattiest lab coat, it provides little protection and may be a source of contamination. Laboratory coats should not be worn outside the laboratory. Personal protection equipment, such as gloves and safety glasses, should not be removed from the lab. 

The description of the method to be used should include details of all practical precautions which will be taken to limit risk, such as the need for ventilation, minimization of inhalation of particulates or aerosols, using fume cupboards or safety screens, and wearing gloves, laboratory coat, and safety spectacles. Handling procedures, packaging for transit, and disposal of unused reactants or products all need to be considered. 

BSL 2 Biosafety Level 2 is suitable for work involving microorganisms of moderate potential hazard to personnel and the environment. Safety equipment Class I or II biosafety cabinets or other physical containment devices laboratory coats, gloves, face protection as needed. Microorganisms include hepatitis B virus, HIV, salmonellae, and mycoplasma. 

Wearing of suitable protective clothing (protective goggles, gloves, gas mask, laboratory coat, etc.). 

A. G. Ekstrand, in his biography of Nilson written for the Swedish Academy of Sciences, expressed admiration that A person can work with chemicals and chemical apparatus in such a neat and truly elegant manner as he does. In the laboratory at Upsala, where I worked beside him for many years, I cannot recall ever having seen him in a laboratory coat (34). Ekstrand described Nilson as a practical chemist, not much given to theorizing. 

The Concise Guides address topics of special concern to psychiatrists in clinical practice. The books in this series contain a detailed table of contents, along with an index, tables, figures, and other charts for easy access. The books are designed to fit into a laboratory coat pocket or jacket pocket, which makes them a convenient source of information. References have been limited to those most relevant to the material presented. 

All experiments must be carried out in a fume hood with the use of proper personal protective equipment such as safety glasses with side shields, a laboratory coat or apron, and the proper gloves for hands. 

Safety glasses must be worn in the laboratory at all times. A laboratory coat and appropriate gloves may be desirable. Material safety data sheets (MSDS), must be read for all chemicals used. 

Protective Garments While working with explosives and toxic materials, workers must wear approved coveralls or laboratory coats (preferably full length) to prevent contamination of their personal apparel. The use of flame-retardant coveralls is desirable for some explosive operations where there is a possibility of a flash. Cotton or other anti-static material should be worn wherever there is a possibility of generation of static electricity. 

Gloves and a laboratory coat should be worn. Use the proper technique to avoid... 

CAUTION Sonication, filtration, and transfer should be performed in a fume hood. Personal protection equipment—laboratory coat, gloves, and safety glasses—must be used. Ear protection should be utilized during sonication. 

Wear neoprene gloves,17 laboratory coat, and eye protection. Cover spill with a 1 1 1 mixture by weight of sodium carbonate or calcium carbonate, clay cat litter (bentonite), and sand. Scoop into a beaker or pail. In the fume hood, slowly add the acid mixture to a pail of cold water. When reaction ceases, neutralize with more sodium carbonate if necessary. When solids have settled, decant liquid into drain with 50 times its volume of water. Discard solid residue with normal refuse. Ventilate site of spillage well to evaporate remaining liquid and dispel vapor.18,19... 

Small Quantities. Wear neoprene gloves, laboratory coat and eye protection. Work in the fume hood. Add slowly to large volume of cold water in a plastic pail. Neutralize with 5% sodium hydroxide solution or sodium carbonate and pour into the drain.18... 

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... 

Wear nitrile rubber gloves, laboratory coat, and self-contained breathing apparatus. Cover the spill with a 1 1 1 mixture by weight of sodium carbonate, clay cat litter (calcium bentonite), and sand. When all of the liquid has been absorbed, scoop the mixture into a plastic pail or other wide-mouth container and place in the fume hood. If local regulations permit, allow the acetone vapor to evaporate for several days until no odor remains. The spill mix can then be discarded with normal refuse.14,15 Otherwise, package and label for disposal by burning.15,16...
