CFC Draft Curtain Requirement in Non-Sprinklered Buildings?

CFC Draft Curtain Requirement in Non-Sprinklered Buildings?

(OP)
Hi,

CFC Table 3206.2 calls for the use of draft curtains in non-sprinklered buildings. In what capacity would they actually be required? According to Table 910.3, draft curtains must contain a floor area of 10,000 SF max. for Class I-IV commodities <= 20' top of storage. My understanding is that draft curtains would not be required under the following conditions:

* The total floor area in the warehouse is under 10,000 SF, AND
* The vent-to-floor ratio meets the required 1:100.

If either of these 2 conditions are not met, a draft curtain would have to be installed to meet both of those requirements.

That is to say, even if the warehouse area is under 10,000 SF, if the ratio is not met, a draft curtain would be required to meet that ratio (or additional vents added). Similarly, if the ratio is met but the 10,000 SF is exceeded, a draft curtain is also needed. Otherwise, if both conditions are met, a draft curtain is not needed.

Do I understand this correctly?

Thanks!

Is this just a general question?

Or a specifc application

You need to start in the building code, it seems like

RE: CFC Draft Curtain Requirement in Non-Sprinklered Buildings?

Sorry read your question wrong

RE: CFC Draft Curtain Requirement in Non-Sprinklered Buildings?

I am thinking less than 10000, the building walls are the draft curtain and no additional are needed,

Look at foot note "j" which might throw out the vent requirement

RE: CFC Draft Curtain Requirement in Non-Sprinklered Buildings?

Foot note j only applies in sprinkled buildings

RE: CFC Draft Curtain Requirement in Non-Sprinklered Buildings?

The draft curtains are not required if the building does not contain high piled combustible storage are not required if the building is sprinklered.

Thanks for the responses. To be clear, I am specifically referring to the scenario where the building is non-sprinklered (so not ESFR where Note j would apply), and IS high piled storage.

My question did include my own answer of the scenario in which I've outlined... I am really just looking for some peer verification that my own answer is correct, or to correct me if I'm mistaken. Thank you!

RE: CFC Draft Curtain Requirement in Non-Sprinklered Buildings?

Trying to use your scenario

Class 1-4

Under 10,000 sq ft

No sprinklers


1 draft curtains not required
