The heating mantle must be able toreach 232 degrees C [450 degrees F] and must have a grounded plug that should be plugged into areceptacle outside the cabinet. CAUTION – The auto-ignition temperature of paraformaldehyde is300ºC (572ºF).6. This step is optional. Place a second heating mantle in the cabinet with 60% more by weight ofammonium bicarbonate than paraformaldehyde. This will be used later in step 13 to neutralize theformaldehyde gas.7. This step is recommended. Place spore strips inside the cabinet to confirm that the decontaminationprocess has been successful.8. If the cabinet is vented to the room, use a sheet of plastic and seal the front access and exhaust portopenings.
