Gloves wearing outside laboratory

Pouring down a stirring rod ensures that no liquid dribbles down the outside of the beaker. The glove in this illustration is omitted so you can clearly see where to place your fingers. Always wear gloves when handling chemicals in the laboratory. 

Caution. Technetium-99 is a weak Remitter (0.292 MeV, 7% =2.12 X 10s years). Therefore, all manipulations should be carried out in a laboratory equipped with a monitored fume hood with Fiberglas trays and plastic-lined absorbent pads used to control potential spills. Personnel should wear disposable lab coats and gloves at all times. Radioactive wastes, both solid and liquid, must be disposed of in special receptacles. Samples sent outside the laboratory must be sealed in glass bottles within a nonbreakable outer container with cotton as a filler, and the glass bottle must be wipetested for contamination prior to ship-... 

Wearing disposable vinyl gloves, cut an approximately 20 X 35 cm (8 x Win) piece of chromatography paper. Be sure to note the machine direction so that the chromatogram will be developed in the same direction. This information can be found on the outside of the original box containing the paper. Alternatively, precut paper can be purchased from analytical laboratory and supply houses. 

The Centers for Disease Control and Prevention (CDC) reported that 41 persons who developed infections from Salmonella Typhimurium were linked to exposure in clinical and college and university teaching microbiology laboratories. About 1/3 of those had to be hospitalized but no deaths were reported. Behaviors associated with illnesses included not wearing lab coats or gloves, not washing hands, using the same utensils and notebooks outside the laboratory. CDC developed a list of precautions to prevent laboratory-acquired infections (LAI). 

Always wear appropriate protective clothing, such as gloves, eye protection, lab coat, and shoe covers (see Chapter 2). Do not wear protective clothing used for radioactive work outside the laboratory.
