When using a tube furnace, there are several precautions that should be taken to ensure safety and proper operation:
1. Location and environment: The tube furnace should be used in a workshop or laboratory with an indoor temperature lower than 40 degrees Celsius and relative humidity lower than 85%RH. There should be no conductive dust, flammable and explosive objects or gases, and corrosive gases that could damage the furnace or its surroundings.
2. Stability and installation: The tube furnace should be installed stably on the ground to prevent vibration and bumps.
3. Regular maintenance: Check the circuit system regularly to ensure good contact and inspect the condition of the heating element. If there is any aging, breakage, or short circuit, it should be repaired or replaced promptly.
4. Rated temperature: Use the tube furnace according to its rated temperature and avoid overheating or overloading.
5. Avoid sudden heating and rapid cooling: Take precautions to prevent sudden heating or rapid cooling due to power failure, as this can damage the furnace and heating wire.
6. Material selection: Avoid using materials with high moisture, volatile matter, or organic matter in experiments with tube furnaces.
7. Cleanliness: Before starting each experiment, clean the furnace to remove any residues or contaminants that could affect the quality of the experimental materials.
In addition to these precautions, there are also administrative controls that should be followed when using a tube furnace:
- Furnace operators should complete safety training specific to the furnace they will work with and thoroughly read the instrument's manual.
- Consult with the manufacturer and your supervisor to ensure that your planned experiments are appropriate for the unit.
- Do not overheat materials or their containers and do not use containers outside of the recommended temperature range.
- Attach an external temperature-controlled power circuit that would cut the power to the unit in the event of elevated temperatures.
- Keep the furnace's wiring tidy and away from other heat-generating sources.
- Do not disable safety features and do not heat a furnace to its maximum temperature.
- Use appropriate safety measures when heating samples or glassware with chemicals that pose respiratory hazards.
- Keep the area around the furnace decluttered and always use thermal-rated tongs or forceps to place and remove items from the furnace.
- Regularly inspect the furnace for any loose or damaged wiring, water and heat damage, or other visual defects.
- Dispose of furnace units that are beyond their usable lifetime.
It is also important to keep the furnace tube clean and sanitary, avoiding any residual substances that can react with the material of the tube. When burning materials, it is recommended to use a boat or crucible to hold them instead of placing them directly on the furnace tube.
Overall, following these precautions and maintenance guidelines will help ensure safe and efficient use of a tube furnace.
