Hazardous Materials & Waste

Research in our lab areas involves the use of various gas and water lines. It is important that these are clearly identified to ensure the correct gas is connected to the correct equipment. In addition, clear identification of both gas and water lines are crucial in the event that emergency responders such as the fire department need to enter a lab area. Learn more about how to identify gas lines. 

Hazardous chemicals must be properly segregated by hazard classification when handled and stored in order to prevent unwanted reactions. These reactions can result in the generation of toxic gases, fire, and even explosions. Read more about how to safely store acetic acid. 

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.
