Does Reference in a Standard Pull in Other Code?

11/28/2022

9 Comments

 
I have a project involving spray application of resin, and an exhaust system including multiple 60-ft tall exhaust stacks.

We are located in Ontario Canada, and the Ontario Building Code takes precedence. Any other codes cited need to be enacted by the OBC, or by a code enacted by OBC in order to be relevant. NFPA 13 is relevant here.

Chapter 26 (NFPA 13-2019) includes material from other codes. Section 26.4 relates to Spray Application Using Flammable or Combustible Materials, and references NFPA 33.

I have not found a reference in NFPA 13 that states that an in-duct sprinkler system SHALL be provided.

It appears to me that Section 26.4 states requirements for IF a system is provided.

Unless otherwise stated, are the requirements of Chapter 26 to be used in isolation, without enacting the full text of the other NFPA Code/Standard cited?

If another NFPA Code/Standard is cited in Chapter 26, is the full text of the cited document to be followed?

Where is the line drawn between the two documents?

I have the NFPA 13 Handbook, and the supplemental text does not clarify this for me. Thank you very much for taking the time to read through this one.

Difference Between Spray Room & Spray Booth?

​Spray Room vs Spray Booth: When to use the requirements for one or the other?

I am working on a flammable spray application and was wondering if anyone has a any good metrics for when to determine if an enclosure is a "spray room" vs a "spray booth".

I am working on a 40-ft by 10-ft enclosure which I would argue is a room, but NFPA 33 provides discernable direction even with Annex sections, especially with "this definition is not intended to limit the term spray booth to any particular design." This shows up in A.3.3.19.

From NFPA 33 2021:

Spray Booth 3.3.19
"A power-ventilated enclosure for a spray application operation or process that confines and limits the escape of the material being sprayed, including vapors, mists, dusts, and residues that are produced by the spraying operation and conducts or directs these materials to an exhaust system."


Annex A.3.3.19:
"Spray booths are manufactured in a variety of forms, including automotive refinishing, downdraft, open-face, traveling, tunnel, and updraft booths. This definition is not intended to limit the term spray booth to any particular design. The entire spray booth is part of the spray area. A spray booth is not a spray room."

Spray Room 3.3.20
"A power-ventilated enclosure for a spray application operation or process that confines and limits the escape of the material being sprayed, including vapors, mists, dusts, and residues that are produced by the spraying operation and conducts or directs these materials to an exhaust system."


Annex A.3.3.20
"The entire spray room is considered part of the spray area. A spray booth is not a spray room."


Based on definitions there are no official metrics to determine when to use either definition.

Is this perhaps a constructed room vs a manufactured structure?

Thanks in advance.

Is New Paint in Paint Booth Properly Protected?

1/19/2021

11 Comments

 
We have been asked if a 20+ year old wet pipe sprinkler system we installed into a paint application room is the correct method of protection for a specific paint product that is currently being used.

The MSDS sheets for a few of the products they now use indicate protection with dry chemical, foam, or water fog.

I have been told that the MSDS sheets typically refer to the product as its being stored and not necessarily as its being applied. The storage is not happening in this room of course, but in approved fire-rated storage cabinets outside the area. None of the typical requirements for alternate protection are met per NFPA 33.

Basically other than the product data sheets, this is a run of the mill paint application area. Nothing automated or fancy.

Anyone have any experience with a similar situation?
