Incompatible chemicals must be stored separately to avoid a hazardous reaction. View the simple chemical compatibility chart and review key points involving proper segregation of incompatible chemicals.
Laboratory glassware requires periodic cleaning to remove contaminants. It is important that it is appropriately cleaned as any residual contaminants can affect experimental results. Read about precautions to use when cleaning laboratory glassware.
Discharge or evaporation of hazardous liquids, wastes, vapors, gases, fumes and dusts to the atmosphere is not permitted. Learn more about how to properly dispose of hazardous wastes.
One particular chemical commonly used in lab areas that is found improperly stored is Nitric Acid. It is a strong oxidizing acid and can cause spontaneous fires when in contact with organic materials. It should be stored in its own separate containment tray inside a corrosives cabinet used for acids. In particular, NEVER store Nitric Acid with flammable solvents and combustibles such as Acetic Acid. Learn more about how to properly store nitric acid.
Designated disposal boxes are commonly used in lab areas for collection of broken and damaged glassware. Broken glass can present a serious cut hazard, so it must be collected in a secure manner to prevent contact. In addition, the broken glass must be free of chemical, radiological, and biological hazards. Learn more about how to properly dispose of broken glass.
Proper identification of chemical and sample containers is important for the safety of lab personnel and emergency responders. Chemicals that are not properly identified could be improperly handled or mixed. Learn more about the importance of chemical labels.
Squeeze bottles are commonly used in laboratory areas. They provide a quick and easy source of commonly used solvents such as Acetone, Isopropyl Alcohol, Methanol, and Ethanol. These are all flammable solvents and care is needed to prevent fires or dangerous chemical reactions. Learn about precautions to take when using and storing squeeze bottles.
Typical laboratory equipment that emits ultraviolet radiation include: ozone generators, germicidal lamps, solar simulators, plasma etchers, UV curing systems, xenon flash lamps, tungsten halogen lamps, and mercury vapor lamps. Learn about UV light protocols.
Lab personnel should follow good hygiene practices in the lab area. This will prevent potential exposure to hazardous chemicals. Learn more about chemical hygiene in lab areas.
Do not use a manual liquid nitrogen fill station until you are included on an applicable Work Activity and you have completed EHS0170 Cryogen training. Learn more about important precautions to take when using manual liquid nitrogen fill stations.
