Butyl rubber gloves

Within the database there may be many chemicals for which butyl rubber gloves provide good protection and we could reasonably anticipate that at least some structural similarities would exist among these chemicals that would help us rationalize the choice of butyl rubber. 

It is found that many nitro compounds fall into the group for which butyl rubber is an appropriate choice, so if a new nitro-containing compound had been synthesized and we wished to choose a glove to provide protection, inspection of the members of the class would suggest butyl rubber as a suitable candidate. In this application, we are using the observation of similarities within a class (the presence of many nitro compounds) as a predictive tool (best handled using butyl rubber gloves). 

Personal Protective Equipment Respiratory protection is required (positive pressure, full face piece, NIOSH-approved SCBA will be worn). When response personnel respond to handle rescue or reconnaissance, they will wear Level A protection that should be worn when the highest level of respiratory, skin, eye, and mucous membrane protection is needed. This level consists of a fully-encapsulated, vapor-tight, chemical-resistant suit, chemical-resistant boots with steel toe and shank, chemical-resistant inner/outer gloves (butyl rubber glove M3 and M4 Norton, chemical protective glove set), coveralls, hard hat, and self-contained (positive pressure) breathing apparatus (SCBA).

In addition to the standard laboratory protection, such as safety goggles and chemically resistant butyl rubber gloves, a personal HF gas monitor with audible alarm and a safety sensor for liquids, as described in Section 10.4, are commercially available [2], For detailed information about the toxic effects of HF, see references Fi5, Wa8 and Re4. 

The final screen summarizes the answers given to the computer and provides the best advice possible from the information and rules supplied (Figure 4). In this example, there were no gloves that met the user s needs, so the computer provided the next best choices. The recommended materials are a moderately tactile (nitrile) glove with probable short protection time or a thick (butyl rubber) glove with poor tactility but probable good protective properties. When safety and tactility requirements can be met, then the most cost-effective choice is provided. 

Small Quantities. Wear butyl rubber gloves, laboratory coat, and eye protection. Work in the fume hood. Add bromine (5 mL) to a large quantity of water (1 L). Slowly add 10% sodium bisulfite (about 120 mL) until all color disappears. When reaction subsides, neutralize with sodium carbonate and wash into the drain. 

Wear butyl rubber gloves, eye protection, laboratory coat, large heavy face shield (if in doubt use body shield also), and self-contained breathing apparatus. Eliminate all sources of ignition and flammables. Cover the spill with a 1 1 1 mixture by weight of sodium...

Containers of dibutyl ether, which have been opened and are more than 1 year old, may contain hazardous quantities of peroxides. Especially if they have screw caps, containers should not be opened, and should be disposed of by the appropriate authorities. When the container can be opened safely, check for peroxides as follows Wear butyl rubber gloves, laboratory coat, and eye protection. Work in the fume hood. Dissolve 100 mg of potassium iodide in 1 mL of glacial acetic acid. Add to 1 mL of the dibutyl ether. A pale yellow color indicates a low concentration (0.001-0.005%) and a bright yellow or brown color a high concentration (above 0.01% and hazardous) of peroxide in the sample.9... 

Wear butyl rubber gloves, protective laboratory coat, eye protection, self-contained breathing apparatus, and protective shoes. 

Small Quantities. Wear butyl rubber gloves, laboratory coat, and eye protection. Work in the fume hood. To a 50-mL, three-necked, round-bottom flask equipped with stirrer, thermometer, and dropping funnel, add 1 mL of water, 3 mL of concentrated hydrochloric acid, and 2 g (0.008 mol) of 3,3 -dichlorobenzidine. The temperature is maintained at -5 to OX by a cooling bath, while 0.2 g (0.0084 mol) of 97% sodium nitrite dissolved in 1.4 mL of water is added dropwise to the solution or slurry of dichlorobenzidine hydrochloride. Stirring is continued an additional 30 minutes after addition is complete. While maintaining the temperature at -5 to 0°C, 16.6 mL (0.16... 

Eliminate all sources of ignition. Wear butyl rubber gloves, large and heavy face shield, goggles, and laboratory coat. Cover spill with dry sand. Scoop into a container and transfer to the fume hood. Decompose by cautious addition of dry butanol (40 mol butanol to 1 mol hydride or 26 mL/g hydride) until reaction ceases. Slowly add mixture to a pail of cold water. Let stand for 24 hours. Neutralize with 6 M hydrochloric acid (cautiously add concentrated acid to an equal volume of cold water). Decant the solution to the drain. Treat the solid residue as normal refuse.4 5... 

Small Quantities. Wear eye protection, butyl rubber gloves,10 and laboratory coat. Work in the fume hood. For each 1 mL of dimethylformamide, add 10 mL of 10% sodium hydroxide solution. Heat the mixture under reflux for 30 minutes, or allow to stand at room temperature for 48 hours. Wash the liquid into the drain.10...
