Using high-temperature vacuum furnace atmosphere Notes
1, in addition to doing the experiment, but do not stay in a high temperature furnace tube area.
2, the experimental work is completed, the absence of people continue to use, please turn off special gases, retain N2 flow tube is maintained at standby temperature and see if there are other power that off and not related, such as: cleanhood lighting, cooking with acid small electric or other, please turn off readily.
3, when dealing with HF, please wear gloves, such as when you accidentally hit HF, please flush immediately with water plus 2% calcium gluconate, rub the wound 15 '.
4, quartz glass products, please use caution to avoid rupture, causing severe lacerations.
5. Avoid breathing the smoke of various gases from the furnace or treatment tank.
6, potassium cyanide (KCN) can not be mixed with acids home, because the two can produce toxic gases of KCN.
7, once discovered impede safe thing, please immediately notify the relevant personnel (technicians, etc.).
8, please conserve water usage.
9, broken wafers, paper, cotton swabs, etc ....... Do not fall into the cleaning tank bottom drainage holes, causing the floor to avoid waterlogging due to poor drainage.
10, the front-end length of the putt, when not to use, make-up in order to avoid contamination.
11, the wafer released into the mouth when, following a boat in the holder, do not touch the stove pipe mouth, so as not to contaminate the furnace tube.
