GENERAL INSTRUCTIONS

This form may be used to submit information under the Significant New
Alternatives Policy (SNAP) program for the review of alternatives to
class I and class II ozone-depleting substances (ODS) under section 612
of the Clean Air Act.  Submitters are required to provide this
information on new substitutes to assist the Agency in assessing the
acceptability of chemicals or processes that are considered alternatives
for ODSs.  A separate notice must be filed for each alternative you are
submitting.

All submissions must be provided in three complete copies.  If
information is to be claimed as confidential, all confidential
information must be excised from one of the copies, which will be placed
in the public docket; the other two copies must include the confidential
material.  If no claims of confidentiality are made for the submission,
all copies must be identical.

The attached “Guidance Manual for the SNAP Information Notice” is
designed to assist applicants in completing this form.  The manual
provides instructions on submitting a SNAP notice, asserting
confidentiality claims, completing the notice form, sector-specific data
requirements, and submitting test data and supplemental information.

3. Generic chemical name (if chemical name of substitute is declared
Confidential Business Information).

Non applicable

4. Specific End-Use

   (a) Describe each end-use that may be reasonably anticipated for the
alternative.  Be sure to provide a broad description          (e.g.
terpene-based semi-aqueous solvent cleaner for electronic parts, or HFC
substitute refrigerant for centrifugal chillers).  For a list of end
uses, see Appendix A to the instructions, beginning on p. 19.

   (b) Identify the ODS and the quantity of substitute (if applicable)
needed to replace it for each end use in pounds (replacement ratio).

(a)  N2 Towers (N2 Generators) are total flood nitrogen inert gas fire
suppression systems whereby the oxygen inside a space is inerted down
below 15% per volume. Combustion can not support a flame below 15%
oxygen inside a space, thereby the fire is extinguished. During actual
N2 Generator fire extinguishing tests at UTeC Labs in Hallowell, Kansas
during 2009, it has been observed by N2 Towers Inc. that the actual
nitrogen discharge vorticity (turbulence) created inside the test space,
separates the flame from the fuel and extinguishes the test fire before
the oxygen inside the test booth is inerted below 15% by volume. By then
inerting the test space below 15% oxygen by volume the test fire does
not reignite.

 

(b) Filtered nitrogen gas is supplied without any Ozone Depletion or
Global Warming effect.

Section B - ALTERNATIVE IDENTIFICATION (Continued)

5. (a) Identify each impurity that may reasonably be anticipated to be
present in the chemical alternative as manufactured for commercial
purposes.  If there are unidentified impurities, enter
“unidentified.”

    (b) Provide the CAS Registry Number if available.

    (c) Estimate the maximum weight percentage of each impurity.  If
there are unidentified impurities, estimate their total weight   
percentages.

Note: Please see Part I- GENERAL INFORMATION, Sections 2 a & b of this
application.

6. Byproducts:

    (a) Describe any byproducts of degradation products resulting from
the manufacturer, processing, use or disposal of the chemical
alternative or chemicals used in the new alternative.  If there are
unidentified byproducts/ degradation products enter “unidentified.” 

    (b) Provide the CAS Registry Number if available.

    (c) Indicate where the byproduct/degradation product is formed (e.g.
during manufacturing, during use, etc.) and the amount or rate at which
it is formed.

(a) Our N2 Generator propellant grain undergoes the following chemical
reaction 4NaN3 + Fe2O3 -> 2Na2O.FeO + 6N2 during discharge.   Clean
nitrogen gas is delivered into the space, which leaves a sinter (a solid
at flame temperature) inside the generator (2Na2O.FeO) a high
temperature stable mixed salt is treated as if it were Na2O (CAS #
1313-59-3) or  NaOH (CAS # 95077-05-7).  This material is contained
within the filter inside the N2 Generator and is neutralized at the mill
when the metal body of the inflator is smelted and recycled. 

(b) See above for CAS #.

(c) See above in answer (a), during use in 100 millisecond discharge of

 Note; Our N2 Generator propellant grains were previously manufactured
by TRW in Mesa, Arizona and undergo the following chemical reaction
4NaN3 + Fe2O3 -> 2Na2O.FeO + 6N2 during our N2 Generator discharge.
Clean nitrogen gas is delivered into the space, which leaves a sinter (a
solid at flame temperature) inside the generator (2Na2O.FeO) a high
temperature stable mixed salt is treated as if it were Na2O (CAS #
1313-59-3) or  NaOH (CAS # 95077-05-7). This material is contained
within the filter inside the N2 Generator and is neutralized at the mill
when the metal body of the inflator is smelted and recycled. 

 

2.  Describe whether and how the alternative is regulated under health
and safety related statutory authorities, such as those implemented by

Part II - ALTERNATIVE-SPECIFIC INFORMATION (continued)

Section D - COST AND AVAILABILITY OF THE ALTERNATIVE

1.  Estimate the cost per pound for the substitute chemical.  For
alternative processes and technologies, describe installation costs
associated with the alternative.  

Answer; Our N2 Generators can protect 1,000 cubic feet for a wholesale
cost of approximately $2,000 US which is the approximate cost for
existing UL Listed stored pressure cylinder, inert gas fire suppression
systems or occupied spaces, sold in the USA today.   

2.  Provide information on production of the substitute.  Include
estimates on:

    (a) Year substitute will be available if not currently produced.
Answer; full scale production capable by June 2010 or sooner.  

    (b) Total pounds production per year (current figure). Answer;
155,138 pounds of propellant in 2010, 1,000,000 pounds in 2011.

    (c) Years to maximum market penetration. Answer; 2 to 4 years.

    (d) Maximum total production per year at market saturation. Answer;
the USA will wholesale approximately $120,000,000 clean agent fire
systems in 2010, this equates to approximately 60,000,000 stored
pressure inert gas fire system bottles and an equivalent number of N2
Generators. .  

    (e) Estimated percentage of market at market saturation. Answer; 80%
of market for N2 Generator fire system for market saturation.  

3.  Describe any new equipment and use profiles.  If retrofitting of
existing equipment is required, detail changes in technologies needed to
use the alternative and address any materials compatibility issues. 
Provide information on each end-use and capital costs associated with
the substitute or alternative process.  Include cost of equipment and/or
any new materials, equipment lifetime, changes in labor and energy
costs.

Answer; our N2 Tower and N2 Generator fire suppression systems can be
used for 100 % of all applications where clean agent fire suppression
and explosion suppression systems are used in the fire system’s
industry today. The wholesale cost of our N2 fire suppression systems is
mentioned above in Section D – 1. 

Answer; an existing halon, compressed chemical and or inert gas, total
flood clean agent fire suppression system can be easily retrofitted with
a N2 Tower fire suppression system because our N2 Tower fire systems
require no discharge piping system. Also, our N2 Towers (c/w N2
Generators stacked inside the N2 Tower) total flood, inert gas fire
suppression system can use existing detection and control equipment to
be put into alarm and actuated (discharged).

Part III - RELEASE AND EXPOSURE DATA

Section C- OCCUPATIONAL EXPOSURE AT MANUFACTURE

For each manufacturing site (manufacturing of substitutes and/or
products containing substitutes):

     (a) Describe the activities in which workers may be exposed to
chemicals.

     (b) Describe any protective equipment and engineering controls used
to protect workers (e.g. goggles, gloves, chemical hoods).

     (c) Indicate the physical form of chemicals at the time of
handling/exposure (e.g. solid, liquid, gas).

     (d) Estimate average and maximum numbers of workers involved in
each activity.

     (e) Estimate average and maximum duration of activity for any
worker, in terms of (1) hour/day and (2) days/year.

     (f) Enter the contact pathway (e.g. ingestion, inhalation, dermal).

     (g) Estimate the average and high-end exposure concentrations
(separated by a /), being sure to provide units of measure.

Answer; our existing stockpile of TRW sodium azide propellant gains will
be shipped to UTeC Labs in Hallowell, Kansas and loaded into our N2
Generators using a down draft loading table inside the UTeC propellant
grain loading facility, as permitted by the local health and safety
authority having jurisdiction in this matter. Glove use is recommended
when loading sodium azide propellant grains but no respirator is needed
for the worker when using a down draft, propellant grain lading table.
N2 Generator propellant grain loading can be performed 24 hours per day
and 365 days per year. Sodium azide is not to be ingested because it is
a poison. Total number of workers allowed in the exposure area is per
building code permitted allowances for that particular space.

Section D - ENVIRONMENTAL RELEASE AND DISPOSAL IN END-USE

For each end-use of a substitute:

     (a) Provide the estimated amount (in kg/day) of each chemical
released directly to the environment (e.g. as a hazardous waste or
wastewater effluent) at a site using the substitute (e.g. in products
containing the substitute and processes using the substitute).

     (b) Identify the media (indoor air, outdoor air, land, water) to
which the chemical will be released from that release point.

     (c) Describe the control technology used to limit release; estimate
the amount released to the environment with the control technology in
place to limit release.  If the substitute is to be disposed of,
indicate the method and location of disposal.

     (d) Are releases covered under RCRA?  If so, identify the RCRA
hazardous waste codes.

     (e) Identify the appropriate number of sites expected to use the
substitute.

     (f) Provide information on recycling of the substitute.  Describe
any associated costs and equipment.

Answers; 

a) This information is provided above in Part 1 – General Information
– section # 2 of this application. 

b) Again, this information is mentioned in Par 1 – General Information
– section # 2 of this application; this information and data of
chemical release happens after discharge of our N2 Generator. 

  

c) We make a ceramic paper and steel wool filter roll/pad which is
inserted inside the N2 Generator and the TRW propellant grains are then
placed inside the filter roll. When the pyrotechnic squibs are actuated
inside both end caps of the N2 Generator they ignite the propellant
grains and the filter pad catches the particulate and clean nitrogen gas
is discharged from the N2 Generator into the protected space. 

d) Our N2 Generator nitrogen release is not covered under RCRA. After
discharge the sinter product left inside the discharged N2 Generator is
considered as sodium hydroxide (re: commercially known as Drano), in an
industrial setting sodium hydroxide is covered under RCRA. However N2
Towers Inc. will provide a “cradle to grave” program for our N2
Generator end users who can, if they wish, ship the discharged N2
Generators back to our recycling facility, which will smelt down and
recycle our N2 Generator metal valve bodies. 

e) In all potential clean agent applications across the USA. 

f) Answered above in (d).

Part III - RELEASE AND EXPOSURE DATA (continued)

Section E - OCCUPATIONAL EXPOSURE AT END-USE

For all end-use scenarios of the substitute (end-uses utilizing the
substitute in products and/or processes):

     (a) Describe the activities in which workers may be exposed to
chemicals.

     (b) Describe any protective equipment or engineering controls used
to protect workers (e.g. goggles, gloves, chemical hoods).

     (c) Indicate the physical form of chemicals at the time of
handling/exposure (e.g. solid, liquid, gas).

     (d) Estimate average and maximum numbers of workers involved in
each activity.

     (e) Estimate average and maximum duration of activity for any
worker, in terms of (1) hours/day and (2) days/year.

     (f) Enter the contact pathway (e.g. ingestion, inhalation, dermal).

     (g) Estimate the average and high-end exposure concentrations
(separated by a /), being sure to provide units.

Answer (b): Occupants located inside a space do not need to wear any
type of protective goggles, gloves, chemical hoods, clothing, dust
respirator equipment or self contained breathing apparatus in which
there has been an accidental N2 Generator discharge. 

Answer (c): The CO2, CO and nitrogen is discharged as a gas into a space
by an N2 Generator the above noted particulate is a tiny solid.   

Answer (d): Total number of occupants which are allowed inside a room
after accidental N2 Generator discharge is as per the existing building
occupancy permit for that particular room. 

Answer (e): After accidental discharge of an N2 Generator if the oxygen
level inside the space is 12 % per volume then the occupants must vacate
the space within five minutes. 

Answer (f): The contact pathway for the above mentioned gas and
particulate levels are by way of inhalation.  

Answer (g): The above noted N2 Generator gas and particulate amounts are
the estimated high end levels after a N2 Generator discharge. 

Section F - CONSUMER EXPOSURE

For each end-use of a substitute:

     (a) Identify the potentially exposed population (e.g. indoor
residents).

     (b) Identify the exposure medium (e.g. air).

     (c) Enter the contact pathway (e.g. ingestion, inhalation, dermal).

     (d) Enter the exposure point of concentration.  Provide (1) average
and (2) high-end estimates.

Part III - RELEASE AND EXPOSURE DATA (continued)

Section G - GENERAL POPULATION EXPOSURE (optional)

For manufacturing of substitutes and products containing substitutes:

     (a) Identify and number potential exposure points.

     (b) For each exposure point described in (a), identify the
potentially exposed population (e.g. residents at the fenceline).

     (c) Identify the contact pathway (e.g. ingestion, inhalation,
dermal).

     (d) Identify the exposure medium (e.g. air, water).

     (e) Enter the exposure point concentration (mg/m3).  Provide (1)
average and (2) high-end estimates. 

Answer; through the use of our stockpile of existing TRW sodium azide
propellant grains our N2 Generator’s only expose the general public to
100 % clean nitrogen gas, as it is discharged from an activated N2
Generator into a space and noted in various sections of this N2
Generator SNAP List application.
