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.

What happened?
- A laboratory researcher suffered a delayed chemical burn after only a few drops of a highly corrosive organic chemical splattered on his unprotected left forearm.
- The burns first appeared hours after exposure, got worse overnight, and eventually required treatment at a hospital.

What Happened?
A 9.4 Tesla superconducting magnet, used for mass spectroscopy in a campus laboratory recently suffered a catastrophic failure. The incident was apparently caused by over-pressurization and failure of the liquid helium (LHe) chamber. Although there were no injuries because the incident occurred during off-hours, the potential for significant injury due to the venting of LHe into the facility was present. There was also significant damage to equipment associated with the magnet.

What Happened?
On April 11, 2007, an employee of Campus Recycling and Refuse Services was alarmed when a suspected compressed gas cylinder ruptured in the rear hopper of a garbage truck. The employee was standing at the rear of the truck and had activated the blade that sweeps the garbage from the hopper into the body of the truck for further compaction. The pressurized gas cylinder was believed to be concealed inside a plastic trash bag. The sweeping action of the blade ruptured the cylinder and the residual contents sprayed into the employee’s face.

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.

What Happened?
A veteran forklift operator with 20 years of experience started his day just as he had often done, then soon realized just how fast things can change. Due to an oversized load, the operator was transporting a dumpster bin on the forks of his forklift while he was traveling in reverse. While in reverse, he hit a curb, causing the forklift to roll over onto its side.
The stunned operator was transported by ambulance to the hospital emergency room, where he was treated for a fractured leg.

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 Happened?
An employee in Campus Recycling & Refuse Services was stuck by a needle while emptying trash bags from a dumpster behind Wellman Hall. The incident happened early in the morning, and the employee sought immediate off-site medical care. A physician dispensed antiretrovirals for a possible Human Immunodeficiency Virus (HIV) exposure, and the employee was very concerned that he might have been infected with a life-threatening disease.

What Happened?
A campus employee working in an electronics shop was repairing a power supply unit. The cooling fan had not been working properly, causing the unit to overheat. The employee replaced the defective cooling fan and then reached into the open top of the power supply unit to check the airflow from the replacement fan. The employee either made contact with a charged capacitor or was close enough (within 1/4") to allow electricity to arc to his hand causing an electric shock that entered his left hand and exited through his right hand.

What Happened?
A UC Berkeley researcher was preparing a sample for microscopy. After he had cleaned the sample with isopropanol, he poured the extra isopropanol into a container for unwanted chemicals labeled “isopropanol.” There was an immediate chemical reaction that caused the plastic container to rupture and spray the mixture around the area. He was later surprised to learn that the container actually held concentrated nitric acid in the form of spent copper etchant.
