Re: Industrial Oven Fire Protection
Dear: Dear Mr. Mustian,
In our investigation as to the requirement of installing a fire suppression system in your industrial oven it was found that the current sprinkler system exterior to the oven in your processing area is adequate in lieu of a suppression system in the industrial oven. I apologize for the delay in this answer. Due to records not being available on the current fire sprinkler system, the age of the structure and missing data plates on the riser it took some due diligence to assure the design of the sprinkler system was adequate to meet your fire protection needs.
I am putting a copy of this letter along with the study completed by Fire Protection Engineer Steve Smith in our address file. This way a record has been established on your sprinkler system for future understanding in this area of the industrial oven and spray booth only.
In the event that your company changes the industrial process or equipment being used please contact the Division of The Fire Marshal for further review.
Raymond K Johnson
Deputy Fire Marshal

Additional Comments: This powder coat booth was discovered by an inspector who determined that this booth and oven were installed with out plan review and permit. Inspection required to submit to AHJ for appropriate review and permit.
Operations using finely ground particles of protective finishing material applied in dry powder form by a fluidized bed, an electrostatic fluidized bed, powder spray guns or electrostatic powder spray guns shall comply with Chapter 15, and SECTION 1506, IFC 2009, as amended. |
|Disapproved||** Please supply manufacturer's installation manual and/or cut sheets with re submittal.
** Please describe the type of application being used:
automated electros tic powder spraying equipment?
handheld electrostatic powder spraying equipment?
electrostatic fluidized beds?
other type of equipment and powder application/process?|
|Disapproved||IFC 2009, AS AMENDED CHAPTER 15 FLAMMABLE FINISHES - 1
Powder coating operations shall be con-conducted in enclosed powder coating rooms, enclosed powder coating facilities which are ventilated or ventilated spray booths.
*** Listed spray booth assemblies should be specifically listed for powder coating operations to ensure that the differences in medium between flammable spray finish and powder coatings are addressed in the protection systems.
*** This powder coating operation is conducted in a listed spray booth, however, it does not indicated it is LISTED FOR POWDER COATING.
PLEASE RESUBMIT WITH THE SPECIFIC LISTING FOR POWDER COATING|
|Disapproved||IFC 2009, AS AMENDED CHAPTER 15 FLAMMABLE FINISHES - 2
Areas used for powder coating shall be protected by an approved automatic fire-extinguishing system complying with Chapter 9.
****PLAN SHEET M111 Notes: "The oven and powder coat booth are covered by a general fire sprinkler system"
**** Fire Extinguishing systems plans and permits shall be submitted to CSFD Construction Services, attention Ms. Dee Withee @ 385-7361. This reviewer cannot determine whether this system complies with Chapter 9.
AUTOMATED powder application equipment shall be protected by the installation of an approved, supervised flame detection apparatus that shall react to the presence of flame within 0.5 second and shall accomplish all of the following:
1. Shutting down of energy supplies (electrical and compressed air) to conveyor, ventilation, application, transfer and powder collection equipment.
2. Closing of segregation dampers in associated ductwork to interrupt airflow from application equipment to powder collectors.
3. Activation of an alarm that is audible throughout the powder coating room or booth.
*** Please identify whether this system is an automated system---refer to additional requirements above if this system is automated.
*** For requirements and additional information or Fire Extinguishing Systems for Powder Coating see:
NFPA 33, CHAPTER 9
Exhaust ventilation shall be sufficient to maintain the atmosphere below one-half the minimum explosive concentration for the material being applied. Non-deposited, air-suspended powders shall be removed through exhaust ducts to the powder recovery system.
*** Resubmit plans and demonstrate that ventilation is sufficient to maintain 1/2 the minimum explosive concentration for the materials.
Note: minimum explosive atmosphere (MEC)
A collection system is required to collect any unused powder. This requirement is similar to ventilation requirement for flammable vapors in its intent to limit amount of vapors or dusts to a concentration that would not support ignition.
NFPA 33, SECTION 15.8 Ventilation, dust collection & explosion protection
***The manufacturer of the powders being used shall provide the MEC of those powders for the purposes of proper design of the exhaust system.
Where non deposited, air suspended powders (powder over spray) is conveyed by ductwork to a recovery system, sufficient airflow shall be provided in the ductwork to maintain the powder concentration in the ductwork to main the powder concentration in the ductwork at not more than 50 percent of the MEC of the powder in use.
Equipment shall bear an identification plate stating the ventilation rate for which was designed. |
***PLEASE IDENTIFY WHICH, IF ANY, OF THE FOLLOWING CLASS OVENS APPLIES TO THIS PROJECT:
FURNACE CLASS A. An oven or furnace that has heat utilization equipment operating at approximately atmospheric pressure wherein there is a potential explosion or fire hazard that could be occasioned by the presence of flammable volatiles or combustible materials processed or heated in the furnace.
Note: Such flammable volatiles or combustible materials can, for instance, originate from the following:
1. Paints, powders, inks, and adhesives from finishing processes, such as dipped, coated, sprayed and impregnated materials.
2. The substrate material.
3. Wood, paper and plastic pallets, spacers or packaging materials.
4. Polymerization or other molecular rearrangements.
Potentially flammable materials, such as quench oil, water-borne finishes, cooling oil or cooking oils, that present a hazard are ventilated according to Class A standards.
FURNACE CLASS B. An oven or furnace that has heat utilization equipment operating at approximately atmospheric pressure wherein there are no flammable volatiles or combustible materials being heated.
FURNACE CLASS C. An oven or furnace that has a potential hazard due to a flammable or other special atmosphere being used for treatment of material in process. This type of furnace can use any type of heating system and includes a special atmosphere supply system. Also included in the Class C classification are integral quench furnaces and molten salt bath furnaces.
FURNACE CLASS D. An oven or furnace that operates at temperatures from above ambient to over 5,000°F (2760°C) and at pressures normally below atmospheric using any type of heating system. These furnaces can include the use of special processing atmospheres.|
