Precautions for using high temperature electric furnace

The following is a description of the precautions we have when using high temperature electric furnaces;

In addition to doing the experiment, do not stay in the high temperature furnace tube area.

When the experiment is completed, if no one continues to use, please turn off the special gas, keep the N2 flow, keep the furnace tube at the standby temperature, and check if there is any other power supply that is off and not closed, such as: cleanhood lighting, small electric furnace for cooking acid Or other, please turn it off.

Wear gloves when handling HF. If you accidentally touch HF, please flush immediately, add 2% water with calcium gluconate, and rub the wound 15'.

Please use the quartz glass products carefully to avoid rupture and cause serious cuts.

Avoid inhaling various gases from the furnace or treatment tank.

Potassium cyanide (KCN) cannot be mixed with acids because both can produce highly toxic KCN gas.

If you find something that is preventing you from being safe, please notify the relevant technician immediately.

Please save the amount of pure water.

Broken wafers, filter paper, cotton swabs, etc., do not fall into the bottom drain hole of the cleaning tank to avoid water stains on the floor due to poor drainage.

The front end of the long and short putter should be facing up to avoid contamination when it is not used.

When the wafer enters and exits the furnace, the holder of the boat should not touch the nozzle of the furnace to avoid polluting the furnace tube.
