Fire Hazard with Immersion Water Heaters

September 30, 2005
Office of Environment, Health, and Safety
What Happened?

It is believed that a Cole Parmer Polystat 12002 immersion heater in a University of California, Santa Cruz (UCSC) microbiology laboratory did not shut off as the water level in the plastic bath dropped, allowing the temperature to rise to the point that the bath material ignited. The fire caused extensive damage to the building and shut down research for several months.

What was the cause?

Immersion water heaters/circulators used in plastic tubs (baths) have been associated with laboratory fires at several universities in recent years. When...

Researcher Smells Toxic Fluorine Gas When Changing Out Gas Cylinder

April 30, 2007
Office of Environment, Health, and Safety
What Happened?

Two researchers were changing out a gas cylinder containing a low concentration of fluorine used in an excimer laser. After reconnecting the regulator, researchers opened the cylinder valve, heard a hissing sound, and smelled a pungent odor. They quickly turned off the cylinder valve and reported the incident to their department safety coordinator (DSC). Fluorine is a very toxic and reactive gas, but fortunately, the concentration was dilute, less than 0.1% fluorine. The DSC contacted EH&S and was advised that researchers involved should be medically evaluated because of...

Missing Guard on Incubator Fan Injures Post Doc

What Happened?

A postdoctoral researcher was reaching into a New Brunswick Scientific Model G-25R Shaker Table Incubator to clean up a spill when her right hand got caught in the spinning exhaust fan blade. She lacerated her middle finger and lost part of the fingernail. She was treated in a local hospital emergency room.

Pressurized Dewar Cap is Blown Off and Causes Minor Injury

February 28, 2009
Office of Environment, Health, and Safety
What happened?

In July 2008, a guest scientist at the Lawrence Berkeley National Laboratory sustained a minor injury when the cap of a 50-Liter liquid nitrogen Dewar burst off and hit his forehead. The scientist needed to fill the Dewar - which hadn't been used for several months - and assumed it was depressurized because of its lack of use.

Without wearing safety goggles or a face shield, the scientist attempted to verify the Dewar was depressurized by pulling a pressure relief plug. The relief plug was not designed to be manually operated (it did not have a pull ring), and it is...

Ladder Fall Results in $19,125 Fine and Serious Injury

August 31, 2009
Office of Environment, Health, and Safety

In 2008 and 2009 UC Berkeley experienced two serious injuries resulting from falls from ladders.

2009 Incident

During the summer a campus employee was disassembling equipment attached to a wall. He was using a wooden step ladder that had been left on-site by a contractor. He did not open the ladder and the ladder was lacking anti-skid material on its feet. The height of his stance on the ladder was approximately three to four feet from the concrete floor. The ladder, which was leaning against the wall, slipped and he fell to the floor and sustained a serious injury to his right arm/...

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...
