Working with High Temperature Equipment and Furnaces

1. Remember that below about 800°C, hot materials do not “glow.” Therefore, be very cautious when picking up anything in the vicinity of a furnace.

2. When you remove a piece from a furnace and place it on the bench to cool, place one of the metal “HOT” signs nearby.

3. Red hot graphite will ignite if removed from a hot furnace into the open air.

4. Do not try to remove an alumina crucible from a furnace that is above 500°C. These crucibles have small thermal coefficients of expansion and may crack or shatter.

5. Never pour water onto molten metal. You may get burned by spattering water and/or metal.

6. Never charge a metal melt with cold scrap. Always pre-heat the charge before adding it to the molten metal.

7. Never look into a crucible of molten metal without a face shield. And always wear full protective gear (glasses, gloves, apron, face shield) when handling or pouring molten metal.
