תאונות מחכימות
פגיעה באצבעות עקב שינוע מכלי אחסון גדולים
בעת שינוע דיואר ובו חנקן נוזלי בגודל 250 ליטרים ובאירוע דומה אחר – שינוע מקפיא 80°- ממקומם הרגיל למקום חדש בפרוזדור ובתוך מעבדה, נמחצו אצבעות המשנעים. במקרה אחד מחיצת האצבעות היתה משמעותית.
Tripping Hazard from an Electrical Cord
A control device was connected to both an electrical supply socket on the wall and a sample in equipment. Due to the socket's location, the power cord extended across the floor, suspended 30 cm above it. A pregnant graduate student needed to refill liquid nitrogen and had to step over the cord. As she did, her foot became entangled in the cord, causing her to trip over it and fall.
A General Power Outage in a Lab Building
A rat entered the faculty’s main electrical cabinet on a Saturday night. The rat’s fur began to smoke, setting off the smoke detection system, which in turn, shut off the entire building’s power supply. The on-call electrician succeeded in fixing the outage only by switching between the building’s main transformers. In the morning it turned out...
An eye injury from an ammonia leak
An ammonia cylinder connection was installed by technicians from the building department. The pipeline
was checked for leaks from the cylinder up to the valve in the lab. The researcher asked the technician to
connect the equipment to the valve....

A student was working in a laser lab along with his lab manager and PI. The student had to connect two plus and minus cables to a power supply. The cables are in red and black colors for plus and minus, respectively. Then...
An Acetonitrile Eye Splash
In a reflux reaction of acetonitrile, while the main medium was heated to 80°C, the condenser spontaneously disconnected from the system, and the reaction medium shot out onto the researcher’s
forehead, reaching his eye...
Waste Splash Causing a Chemical Burn
During a waste handling in the lab, a student took a 5 liters waste container out of the chemical hood. While slightly tilting the container out through the sash, liquid waste spilled onto the student’s arm, penetrated through the lab coat and thick clothing, and contacted his skin, causing a chemical skin burn.
Uncontrolled exothermic reaction
In a trial to improve an established polymerization reaction, the catalyzing agent was added in a different order than in previous procedures consisting of the same reactants. The reaction resulted in a minor explosion...
Skin Exposure to beta-Mercaptoethanol
A student was working in a fume hood with beta-mercaptoethanol (β-ME). The bottle’s cork was broken and glued with parafilm. The bottle was not placed in a secondary container. The student lifted the bottle by its cork, the β-ME bottle fell, the liquid spilled through the front ventilation opening in the chemical hood onto the student's hand.
An Eye Splash
A student was working on a bench in a biological-chemical lab with a filter inserted into a 50 ml Falcon tube. While closing the tube’s lid, a chemical was splashed into the student’s eye...
Pressurized liquid nitrogen dewar outburst
While entering the cold room, a student was hit by a pressure safety valve projected from a pressurized liquid nitrogen dewar...
Bursting of a PVC pipe
Three students were working at the lab on a late afternoon while hearing a loud bursting sound. The students immediately evacuated the lab, shutting the door behind them...
Lentivirus II splash on hand
While working in a biosafety cabinet an overfilled capped Eppendorf was opened and a solution containing lentivirus vectors was splashed onto bare skin...
פליטת אדים בלתי צפויה מריאקציה
במהלך יצירת "ספריות חיידקים" בפקולטה לביולוגיה, במהלך אחד ממחזורי זריעת החיידקים טיפות אתנול בוערות מהמסרק ניתזו והדליקו את אמבט האתנול המצוי בקירבת עמדת הניסוי.
דליקה באמבט אתנול בפקולטה לביולוגיה
במהלך יצירת "ספריות חיידקים" בפקולטה לביולוגיה, במהלך אחד ממחזורי זריעת החיידקים טיפות אתנול בוערות מהמסרק ניתזו והדליקו את אמבט האתנול המצוי בקירבת עמדת הניסוי.
נתז KOH לעין בפקולטה להנדסה כימית
Chemical Stored on Floor Causes Fire
A simple mistake caused this incident. During an experiment in the fume hood, the users temporarily set a 4 liter glass bottle of cyclohexane on the floor beside the hood.
Lab Worker Nearly Killed While Working Alone
Two years ago a senior researcher was nearly killed at University of Wisconsin - Milwaukee while he worked alone in a laboratory the evening of July 4th. His distillation flask exploded.
