Dear Mr.,Poskin: • ,
As we discussed on the phone yesterday a new,Eagle Hardware & Garden is planned in your jurisdiction in the ' , •

.. be using to achieve compliance with the Uniforn Build ng•and Fire Codes: It is also. anticipatedthat this ' • •
document will assistyou during the' plan check process by providing the basis on which the design criteria was
developed. Based on the •inforrnation that was exchanged during our phone conversation, we understand that you -
are currently using the 1994 Editions of the Uniform Codes. "Accordiagly; this plan;is based specifically on the . •

It is, however, requested that a variance to the curtain board requirements in•Article il I of the 1994 INC and ,
Article.9 •of •the-1994.UBC be• allowed. Section 103•.1.2 in the UFC and Sections X 04.2.8 and I04,2.9 -in the UBC

(1)' • Curtain Boards in Sorinklered Building, Roof vents and curtain boards were originally used as an aid to , •
. fire fighting in unsprinldered buildings. In an unsprinklered building; roof vents, augmented by curtain

• (1-7 spririklered buildings,, vents and curtain boards are of much less value because the operating sprinklers have

• When curtain boards are installed all of the hot gases tend to be confined in one area (zone) of the ceiling.
Because curtaiii boards prevent the spread of smoke and hot gases in advance of the fire(see Fig. 1), •
• additional sprinklers that.would normally activate are unable todo so in a timely manner: This ultimately.
reduces the effectiveness of the pre- wetting action, and could, eventually result in uncontrolled fire growth: •

(3) Thickness of the•Upper Smoke Laver: A major concern has developed regarding the thickness of the upper
smoke layer at the ceiling level over the fire. Recenttesting has shown that smoke logging in the fire area •
. can occur when the ceiling.sprinklei discharge passes through'the hot sinoke layer. •This.issue was brought
to the attention of the Article 81 Rewrite Committee by the'Natibnal Institute of Standards and Technology
(NISI) Building and Fire Research.Laboratoryy(BFRL) Test Pro'grata called LAVENTS (Link Activated
Vents and'Sprinklers). . This testing demonstrated that if the ceiling smoke layer above the fire is allowed to •
get to a certain depth or thickness, it can actually result in the smoke and heat being drawn downward by a
venturi type action created as discharge from the operating sprinklers passes through the hot gas' layer.

•
• • While the actual critical depth of the smoke layer'is not specifically known, it is thought to be three feet or ,
less. By adding 6 fool: or 4. foot,curtain:boards, the thicknessofthe smoke layer is increased in the general .
. , . area where the sprinklers will be operating. This thickened smoke layer could eventually result is smoke • .
.;, , logging throughout the building... This plteriomena was recently observed at a full scale fire test at .' .
' , . Underwriters Laboratories. It is very importanitto' keep this phenomenon from happening because it will '
' - ' . hinder fire fighters, from getting to the seat of the fire which is important in a high piled stock fires. often • ' .
• the completeextinguishrnentof these types of fires is dependentupon fire fighters with band hose lines. • ' .
(4) • Skingina Sprinkles Heads, The activation of sprinklers are..affected by many factors, including the • ,
temperature and velocity of the hot gases at ceiling level (referred to as the ceiling jet). It is important that
thie ceiling jet be as smooth and uniform as possible. ,Recenttesting and computer modeling has shown • '
' ' , ' that installing draft curtains will cause turbulence as the ceiling jet makes contact with the draft curtain.
• . • ' . , 'This turbulence could delay the response Oft sprinklers and cause skipping of sprinklers immediately •
' • adjacent to the curtain boards., •As a firein the rack advances toward a *curtain board location, the concem,is.
• ' ' that the sinooth, uniform flow of the.ceiling jet will disturbed sufficiently by the �curtain:board to• prevent •
• the operation of the sprinkler heads on non - fireside., The turbulence effect is not all that different from
• • ' • : ' the effect an orifice plate or sudden contraction or bend can have on water flow a pipe: It is known that
. • . • ' it takes alnnost.ten pipe diameters downstream for the•water flow to even Out Where all physical • , •
, . , characteristicathe same,.this.would equate to ..80 #t,ofsiaoke travel for a 4 ft. deep curtain board. In . • •. actuality, the ceiling jet is able to•settle out much quicker, but the generalresult is the same. .. • • ••
• , :. The results of present testing analysis of past data clearly indicate that Curtain boards provide no benefit in a .
.spriniciered boil ri ding but could clearly *cause problems. ', Thisconclusion has become widely accepted within the fire ' '
'industry: • We believe the elirtunation of the curtain board requiretneiits will provide superior•fire protection for this.' '
facility.
•
• Based on the above mentioned test results and the latitudeprovided in Sections 103.1.2 and 103.1, 3 of the Uniform . :
,, Fire Code, we propose,to increase the vent area td 'floor area ratio front .1,'100 to 1 :75, and delete the curtain boards,

• altows.this .latitude:: Our Fire Protection Policy requires evacuation procedures to .begin as soon as a fire is detected
and all of the employees' areinstnutedto assist in evacuating-the building. We do not want the. employees to take
•
time to try and a fire with 1•-1/2 inch hose lines in high pile stock areas. This is a' dangerous fire fighting ' •
procedure: The presenceof.this hose. only tempts employees to engage in fire fighting when they 'should be .
• ' . directing their energies to the evacuation of the customers and themselves from the building. ,
To summarize our reasons for this request: . • • •• • ' ; . • •
. • • (1) . Fire Departments carry their own' hose packets and.wouldnot use this equipment. , •
• .. (2) , ;' Store employees are directed specifically not to use this equipment, but'to assist in the evacuation of the ' .

(6) , There is extra fire protection design' in the building to make this equipmentunnetessary. • • ,

The questions one hasto ask are: who "is going to use the equipment and how will the equipment benefit: These

• . •.It is the policy of Eagle Hardware and (3arden to delete the installation of smoke detectors in the Air Handling ' •
Unit (AHU): supply ducts: The justifications for this policy are follows: : .. . ,
• • : ,(1) • . •It has been Eagle.Hardware.and Garden's experience. that the dusty conditions.comrnon to a home ' • '
utiprovement retail store of this type result in a significant number of false alarms, which not only create •
' . a•burden on the :fire depart rent, but also tend to desensitize the store employees to, the importance of the'
', . -fire alarm. .
. (2) • • . It is,conimonly thought that•the duct smoke detectors will .provide some degree of of warning :
if a fire occurs in 'the storage •areas of the store. , Early not the intent of this section of the •
. • • • code, shut down of the, AHUs is Also, the Iarge volume• of air•in the store and,the .constant air flow will
• ' most likely result in dilution effects;•and the sprinkler system Will probably react to the'fire before the
• . • • .. • .smoke detectors do. , • •
' , • • (3) If shutdown of the AHUs is absolutely' necessary, then a connection to the sprinkler •system flow switch •
• • ' would provide a imuch more,reliable means Of accomplishing that function. This method of providing,
' automatic shutdown is recognized as an acceptable, alternative method by Appendix section A -4 -4.3 of '. . . •

multiple occupancy hazards. Round off calculations to neatest whole cumber. NOTE: THE
