In last month's column ( January/February 2002, p. 33 ), Ted Jablkowski, P.E., eastern regional manager at Cleveland-based North American Mfg. Co. Ltd., explained the importance of safety training in the heat processing arena. Ted is a principal member of NFPA 86 Technical Committee and a member of Industrial Heating Equipment Association's (IHEA) Safety Standards and Codes Committee.
To demonstrate how important safety training is, Ted cited part of the NFPA 86 Standard for Ovens and Furnaces standard as well as its foreword.
This month, Ted continues his response to my question "Is safety training important?"TJ: Additional [safety training] requirements are outlined in NPFA 86 Chapter 10, Inspection, Testing, and Maintenance, as follows:
10-1 Responsibility of the Manufacturer and of the User

10-1.2* When the original equipment manufacturer no longer exists, plant personnel shall develop adequate operational checks and maintenance procedures.
10-2* Equipment Entry. The user's operational and maintenance program shall include procedures that apply to entry into equipment in accordance with all applicable federal, state, and local regulations.

Foreign material, parts, and residue shall be removed from recirculation blowers, exhaust blowers, heat exchangers, burner and pilot ports, combustion blowers, ductwork, and equipment interiors. Ductwork shall be checked for obstructions. Cleaning frequency shall be determined by process requirements.
10-5 Tension and Wear. Recirculation and exhaust system blowers that are driven by V-belts shall be checked for belt slippage and excessive belt wear. If slippage is detected, belts shall be adjusted or replaced.
