Safety presentation for DNI What is inside the glove boxA glove box is a sealed container that isdesigned to allow one to manipulate objects Materials in the glovebox where a separate atmosphere is desired .
1 Air sensitiveTwo types of gloveboxes exist 2 Water sensitive1 allows a person to work with hazardous 3 Toxicsubstances4 Biohazard.
2 allows manipulation of substances that must becontained within a very high purity inert atmosphere 5 Radioactive our lab now General introduction of glove box in our labAr cylinder.
Organic solventsAnd users boxes Safety Features of a Glove Box Positive pressure to the atmosphere if there is leakage in the glovebox it will be in the lab .
Glove boxes will automatically close their valves when there isn t a properpressure of compressed gas If the glove box cannot be refilled with inert gas the glove box can remainfor a few hours to a few days Moisture and Oxygen sensors.
General introduction of glove box in our labSupercapacitor part Battery part Transfer sample into gloveboxChambers change the air environment into inert atmosphere by vacuumingthe chamber and refilling the chamber with gas in the glove box.
Large chamber There is limited space in the glove box so large equipment should bekept to a minimum Check the possibility with super users first Small chamber 1 Ensure equipment can withstand vacuum conditions.
2 Glassware Glassware should be dried in an oven for at least a fewhours before bringing it into the box If you cannot do this you canremove much water from the glass by doing a rinse with EtOH orMeOH then hexanes Flame drying is also an option 3 Chemicals non volatile solids should be opened and covered with.

Transfer hazardous chemicals into gloveboxConsider the solvents that are being used in the glove box and are being brought intothe glove boxWhat are their boiling points Are they halogenated Could they contain water General rules .
Whenever shipping any chemical into the glove box it is important to look at thecharacteristics of the chemical Will it react with the chemical inside the glovebox dorisk assessment Depending on the boiling point of the chemical it could evaporate due to the dip inRefer to the MSDS for moisture level.
Check the label to see it s purity the impurities may be trapped water or solvent easier rule chemicals that have never opened in the air is preferred View of glove boxLeft Right Glove box practices check list before start.
Before using the glovebox 1 Inspect the condition of the glove box Gloves Are there tears Are they firm 2 Compressed Gas Are there any leaks When was the regulator fitting lastchecked Are there gas in the bottle Ar bottle 3 Ante chamber Are there any products equipment .
4 Vacuum Pump How is the pump oil level Does it sound like it s working properly Are there any leaks Before putting your hand in the glove box put on a pair of glove fingercan be sharp to the glove box and ensure hands are dry Enter the glove box slowly if you enter to suddenly you may rip off the.
Before the operation in the glove box put on another disposable gloves toensure the cleanness of the black glove Rules when using the glove boxMaintenance diligence and proper inspection when working in a glove box willprevent many incidents.
Be careful when using sharp things inside glove boxBe mindful of the side products if the reaction generates a harmful gas maybe it isn tthe right reaction to be done in the glove boxIf O2 and H2O level is increasing fastOr beyond 50 ppm.
Contact super user immediately Emergency SituationsAt any time users should be prepared for If there is a loss of power to the panel the following emergencies to occur there is NO safe way to introduce inert Power failure gas into the glove box .
Loss of gas pressure Depending on the state of the glove box Glove tear repair and their regular maintenance gloveboxes can last anywhere for 12 48hours without a refill of gasIn all instances the user s safety is most.
In cases of pressure loss stop using The glove box seal itself until thepressure is sufficient to continue regularPlease keep the glove box tidy and clean Separate trash and sharp.
Clean after use Use a log book Questions Suggestions Or need a hug.
