The inside of a kiln after shutdown is a hostile and dangerous environment. When the kiln starts to cool down there is the uncontrollable build up of coating and thermal conditions that create an environment of danger. The coating can shrink or expand and tumble down with hardly any warning. We always recommend removing the coating with a tear out machine prior to going into the kiln. For situations where it is not practical to remove the coating we developed the Safety Inspection Cage as a safe haven when entering the kiln under coating.
We believe that some protection is much better than no protection and was a primary consideration when we designed the Safety Inspection Cage. We firmly believe the Safety Inspection Cage is not the proper answer and that common sense and good judgment should always be exercised. But the Safety Inspection Cage may help prevent a minor separation of material from the kiln roof from turning into a major injury or loss of life. We designed the Safety Inspection Cage to be installed and adjusted in a way that will allow the users to push the roof of the cage near (never against) the bottom of the coating. Then if the coating does break free it will only fall a short distance onto the roof of the Safety Inspection Cage. It was designed for easy assembly and has handles to assist in moving the cage into position.
