20 years of scientific laboratory research accidentally destroys due to a minor mistake of a vacuum cleaner at a medical scientific research center in the United States.
According to US media, an employee hired by a private company providing cleaning services under a contract between the Rensselaer Institute of Applied Sciences in New York State heard alarm signals from a laboratory refrigerator containing samples for scientific research.
After hearing the alarm, the employee of the private company turned off the refrigerator.
According to foreign media, there was a manual on the door of the fridge to turn off the beeps, but the employee misread it and turned off the circuit breaker.
According to reports, due to this mistake by the employee, the samples stored at minus 80 degrees Celsius were spoiled, causing a loss of 1 million dollars.
Reports state that the cleaner thought he was turning on the circuit breaker when he turned it off.
By the time experts found out, the temperature in the refrigerator had reportedly risen to 50 degrees Celsius and was only minus 30 degrees Celsius.
