“Socket” for laboratory safety

“Socket” for laboratory safety


The unit recently moved a laboratory, and I was deeply moved. The socket problem in the laboratory caught my attention. I want to share with you.

At the beginning, the decoration company said that many of the instruments in the laboratory were high-power, so the sockets were installed as 16A sockets. But soon the problem came out. In fact, the patch panel and most of the instruments in the laboratory are 10A jacks, and the 16A ones are a bit too large. They have no choice but to communicate with the decoration company.

The 16A socket is a high-power socket. Only muffle furnaces, sterilizers, air conditioners and other equipment are needed in the laboratory. However, there are many times when such a problem exists. All of the labs have 10A sockets, but there is no way to change the power cord of the instrument to 10A.

So this time I took the strategy of keeping half and changing half. Note:The hole distance of 10A socket is about 8mm, and the hole distance of 16A socket is about 10mm.

Many of the instruments in the laboratory are imported instruments. In the early years, my country did not have a national standard for sockets. In order to meet everyone’s needs, enterprises produced universal sockets. The advantage of the universal socket is that the power cords of the European and American countries can be used. But the disadvantage is that the socket is easily broken and unsafe for children. Earlier, I walked through all the local supermarkets and found that all the outlets in China are now national standard outlets. what does this mean?

Many instruments in our laboratory cannot find the plug-in board for their power cords, or there will be no plug-in board available after this year. If the power cord is an active power cord, we can choose to replace it.

However, if the power cord and the machine are all in one, there is a problem. Only the surgical method can be selected for cutting and replacement. If you are in a European or American country, this is to be recalled!
This also reminds us that we should pay attention to the socket of the laboratory. When the laboratory enters the instrument, we must check and accept the power cord of the instrument. Only power cords that meet our national standards are qualified power cords. I saw a message on the Internet, and share with you:

A few days ago, the staff of Jiangsu Changzhou Inspection and Quarantine Bureau found that a batch of 3D microscopes from the United States on the spot found that the power plug was a round and flat American standard plug, which did not meet the requirements of China’s mandatory national standards, and there was certain safety. Hidden dangers.

In this regard, the inspection and quarantine personnel on the spot judged that the batch of 3D microscopes were unqualified, and issued a”Notification of Inspection and Quarantine Treatment”, requiring enterprises to effectively rectify the equipment plug.
Today’s theme may be a small point, but it is my own practical experience, I hope it can help everyone’s work. These issues are issues outside the experiment, and are issues that we need to really care about. The double-hole cable without grounding wire is only suitable for low-power appliances such as mobile phone chargers, hair dryers, razors, desk lamps, etc., or Class II appliances with insulation protection such as electric blankets. We saw many instruments in the laboratory were artificially removed the ground wire, which is very unsafe.
