KETTLE SAFETY INSPECTION CHECKLIST
Regular inspection and maintenance of units is essential to obtain trouble free and safe operation of
equipment. Inspections must include testing of the pressure relief valve and checks of the operating
system to insure that it has not been altered.
No safety features designed into the equipment should ever be tampered with. Tampering
with or bypassing controls is a very dangerous practice and unfortunately we have seen several cases of
this. Following is a short list of the most common and the most dangerous alterations performed on kettles.
