Atmospheres
When an optional gas inlet is fitted there is a label near the inlet saying "INERT GAS ONLY". In
practice inert or oxidising gases may be used, but not combustible or toxic gases. Chamber
furnaces are not gas tight, so it should be understood that gas usage may be high, and that the
chamber is likely always to contain some air. Residual oxygen levels of 1% are to be expected.
If a metal retort is supplied with this furnace, please see the supplementary manual MS05.

Operator Safety
The furnace incorporates a safety switch which interrupts the heating element circuit when the
door is opened. This prevents the user touching a live heating element, but also prevents the
furnace from heating up if the door is left open.
Avoid burns. Carbolite can supply tongs, face masks, and heat resistant gloves. Before you
remove a hot object from the furnace make sure you have a safe place to put it down.
