Another member of staff was also taken to hospital after being injured in the incident.
One eye-witness who lives nearby told us that she first heard fire engines before seeing police cars and ambulances at the scene.
The Scottish Government, which runs the laboratory as one of their Marine Scotland facilities, confirmed the building has been closed and indicated.
Police, fire and ambulance crews were called to the yard of the laboratory, which backs onto Abbey Road from Victoria Road in the Torry area of the city, at about 10.45am.

‘I got a scare that somebody has been injured’
A resident, who lives nearby, heard the fire engines rushing to the scene of the incident.
The eye-witness, who wished to remain anonymous, said her first reaction was to call some of the laboratory employees she knows and make sure they are okay.
She said: “I heard the noise of the fire engines and popped to the window. I saw the police cars and the ambulance and then there were some covers on the ground.
“I got a scare that somebody has been injured, so I grabbed the phone and started calling and messaging people I know who work there to make sure they are okay.”

“He was taken to Aberdeen Royal Infirmary for treatment to injuries, which are not thought to be life threatening.
“The Health and Safety Executive has been made aware of the incident.”
