Corrosive Waste Spill

August 31, 2015
What Happened?

A UC Berkeley researcher was working in a lab with a highly corrosive sulfuric acid and hydrogen peroxide (piranha) solution to clean the surface of a glass sample in a fume hood.

After completing the work, the researcher found the existing waste container to be greater than 75 percent full. Rather than add the recently used piranha solution to the already overfilled waste container, the researcher found an additional empty waste container and attempted to pour off some of the overfilled waste into the empty bottle.

During this attempt, some of the corrosive...

Glove Selection Guide

Follow these steps to choose the appropriate type of protective glove for your job. The Glove Selection Chart also provides advantages and disadvantages for specific glove types. This guidance was prepared for laboratory researchers but may also be helpful for other people working with hazardous materials.

Once selected, glove use requirements for your lab should be posted in your Chemical Hygiene Plan flipchart under the Standard Operating Procedures section.See below for the...

Non-Ionizing Radiation (Non-Laser) Manual

The modern world is full of devices that, either directly or indirectly, act as sources of non-ionizing radiation (NIR). These sources produce NIR in the electromagnetic spectrum of wavelengths/frequencies ranging from 100 nm to static fields. Many NIR sources are present on the UC Berkeley campus, either in research applications or in ancillary equipment. In general, NIR tends to be less hazardous to humans than ionizing radiation (ionizing radiation has a wavelength of less than 100 nm or a photon energy greater than 12.4 electron Volts). However, depending on the wavelength/frequency and...

How do I properly clean a lab or shop for deactivation?

Lab and shop deactivation is dependent on the history of work or research conducted in the space.

Chemical decontamination of spaces and equipment may be done by the following personnel:

Laboratory supervisors, researchers, or investigators who can effectively disinfect the equipment themselves and provide certification by signing EH&S’ Facilities/Equipment Decontamination Clearance Certification. Hazardous Materials contractors approved to provide such services to the campus, managed by EH...

How are chemicals relocated or disposed during decommissioning?

Chemicals will have to be moved or removed by a qualified contractor managed by EH&S. It’s possible that EH&S can help move small amounts of chemicals, but will have to be determined.

Chemical transportation is regulated by US Department of Transportation standards and must never be conducted with personal vehicles or department/campus vehicles.

Chemical disposal requires EH&S signatures. Signing disposal manifests by unapproved personnel is a legal violation resulting in citations from the California Environmental Protection Agency.

My lab or shop is moving, what I do I need to do in order to properly vacate?

Contact EH&S as soon as possible for planning to vacate a laboratory or shop space. Vacating technical workspaces may require furniture, equipment, and chemical moves along with cleaning and chemical inventory updates.

In general, equipment and items for relocation need to be free of contamination before moving, giving to Excess or discarding. Laboratories, shops, etc. also need to be cleaned prior to re-occupancy.
