. Flammability: Provide any information on flammability concerns. For example, if any abatement techniques are being used to minimize the risks associated with flammable substances or mixtures, detail those techniqu es below. If a substitute is flammable, an

assessment of overall risk in each end

- use may be required. For flammable refrigerants, provide a fault tree analysis for each end use.

For flammable foam blowing agents used in spray foam, provide a training p rogram that addresses flammability concerns specific to this

substitute. (See Appendix B to I nstructions for sector

- specific data requirements for flammable substances).

The proposed substitute is safety classified A3. So it is important to apply strong s afety measures. The substitute is filled into a copper tube (thermosiphon)

after it has been evacuated to hard vacuum

. Filling is done on a mass basis. There is small (less than 0.02 g) of substitute released during each filling

process . The substitute is s ealed within the copper tube by pinch

- off technique and is therefore hermetic . The filling station is situated in a large well

ventilated factory of 40,000sq.ft. with 20ft ceiling. Throughput is 20 units per day. No open flames are allowed in the vicinity of the filling station. Two

valves are used on the filling line in order to avoid accidental release of gas. A capillary line in the charge tube ensures that flow rates are restricted under any circumstance . Written procedures with checklists are mandator y. We do not have a fault

- tree analysis.

In the end

- use product, a very low temperature freezer for use in bio

- repositories or research establishments , the substitute filled thermosiphon tube is

foamed into the steel

- walled cabinet and connects thermally a t its top end to the cold side of the Stirling machine. The evaporator part of the thermosiphon is located around the inner liner of the freezer. This inner liner is from steel and protects the thermosiphon. The tube is not subject to movement or potential stresses that could cause rupture. The substitute refrigerant is at no point exposed to any moving parts as is the case with conventional refrigeration equipment

. The total use of this hydrocarbon is less than that found to be “acceptable subject to use c onditions” for isobutane, propane and R

- 441A for use

in Retail Food Refrigerators and Freezers as published in the Federal Register Vol 76, No 244 (100g versus 150g). The thermosiphon material, copper does

not react with the substitute and since the assemb ly is hermetic, isolated from user interaction, static and well protected from potential damage, we believe that it is in a secure and safe arrangement regarding the user.

If the very low temperature freezer requires service for which the substitute must b e removed, it is fully recovered. Applying a special penetrating tool to the pinch

- off fill

- tube that allows the recovery equipment to access the substitute does this . If the thermosiphon is refilled, then it will be pinched off below the penetration point in order to re

- hermetically seal the system.

Signs and notices will be placed permanently in 1⁄4 inch (or bigger) letters as follows:

(a) “DANGER

— Risk of Fire or Explosion. Flammable Refrigerant Used. Do Not Drill or Puncture Inner Liner ’’ Located on inner liner of freezer.

(b) ‘‘DANGER

— Risk of Fire or Explosion. Flammable Refrigerant Used. To Be Repaired Only By Trained Service Personnel. Do Not Puncture Refrigerant Tubing.’’ Located in the mechanical compartment at the top of the freezer.

(c) ‘‘CAUTION

— Ris k of Fire or Explosion. Flammable Refrigerant Used. Consult Repair Manual/Owner’s Guide Before Attempting To Service This Product. All Safety Precautions Must be Followed.’’ Located in the mechanical compartment at the top of the freezer.

(d) ‘‘CAUTION

— Ris k of Fire or Explosion. Dispose of Properly In Accordance With Federal Or Local Regulations. Flammable Refrigerant Used.’’

Located on the exterior of the freezer.

(e) ‘‘CAUTION

— Risk of Fire or Explosion Due To Puncture Of Refrigerant Tubing; Follow Handlin g Instructions Carefully. Flammable Refrigerant Used.’’ Located near the condenser section in the machine compartment.

The thermosiphon will be marked in red, Pantone® Matching System #185. There are no service ports or service aperture fitting s. There is a fill

- tube that is pinched

- off after evacuation and filling of the substitute.

Spark

- proof electronics are used throughout.

Leak rates and their likelihood from manufactured and / or repaired equipment are anticipated to be equivalent or less than t hat ex pected of refrigerator best practice. The procedures are identical but in our case there are fewer joints, no internal moving parts and no significant vi brations, even during transport. The machine compartment is positively ventilated during operation.

We anticipate that the alternative (substitute) will be subject to the same requirements under the Clean Air Act and SNAP ruling as the currently allowed hydrocarbons, i.e. “acceptable subject to narrowed use limits” (Federal Register Vol. 76, No 244) . Maximum quantity would be limited to 150 grams (5.3 ounces) in very low temperature freezers. Our current use is 10 0 grams ( 3.5 ounces) per freezer

. Full recovery techniques using appropriate equipment will be required for any r epair and maintenance that involve discharging the thermosiphon (removal of substitute)

.

The alternative is not listed on the “original list o f hazardous air pollutants” Reference: http://www.epa.gov/ttn/atw/188polls.html The alternative has been determined by the EPA to have negligible photochemical reactivity . See US EPA Definitions of VOC (as of January 2009) 40 CFR Part 51 Section 51.100 Definitions.

2. Describe whether and ho w occupational, consumer, or general population exposure to the alternative is regulated under health and safety related statutory authorities, such as those implemented by the Food and Drug Administration (FDA), the Occupational Safety a nd Health

Administ ration (OSHA), the Department of Transportation (DOT), and state and local laws. List any concentration

- based or other numerical standards to which the alternative is subject under the above statutes and regulations. Also list any other standard

- setting organizations such as the National Fire Prevention Association (NFPA ) the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE), or Underwriters Laboratories (UL) that will evaluate the substitute from a health and safety pers pective

.

OSHA requirements : 29 CFR part 1910, specifically 29 CFR 1010.94 (ventilation), 29 CFR 1910.106 (fla mmable and combustible liquids)

and 29 CFR 1910.110 (storage and handling of liquefied petroleum g ases). We think that 29 CFR 1910.1000 (toxic a nd hazardous substances) does not apply because the proposed substitute (ETHANE CAS No. 74

- 84

- 0) is not listed in Table Z

- 1

– LIMITS FOR AIR CONTAMINANTS and is also not listed on the “original list of hazardous air pollutants” at the EPA site http://www.epa.gov/ttn/atw/188polls.html

.

We believe that transportation requirements of the end

- use product (very low temperature freezer) would be regulated under 49 CFR 173.174 (refrigerating machines). UN 3358 Class 2.1 REFRIGERATING MACHINES containing flammable, non

- toxic, liquefied gas. The end product will also be controlled by IATA special provision A103 as follows: Flammable liquefied gases must be contained within refrigerating machine components. Th ese components must be designed and tested to at least three times the wo rking pressure of the machinery . The refrigerating machines must be designed and constructed to contain the liquefied gas and preclude the risk of bursting or cracking of the pressure retaining components during normal conditions of transport. Refrigerating machines and refrigerating machine components are considered not subject to these Regulations if containing less than 100 g of flammable, non

- toxic, liquefied gas.

Threshold limit value time weighted average data from Guide to Occupational Exposure Values (ACGIH 2005) gives 1000 ppm 8 hours for

the alternative.

It is not clear if UL471 applies to the end

- use category of Very Low Temperature F reezers. We have not found a UL standard that would apply to this alternative for the application proposed. We are in process of obtaining UL certification for the end product, i.e. the Very Low Temperature Freezer.

### 11 Part II

- ALTERNATIVE

- SPECIFIC INFORMATI ON (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 c osts associated

with the alternative. Please describe th e information used as the basis for this cost estimate

. Cost of substitute (R

- 170, ETHANE) is about $9.50/lb. (cost fluctuates , this is from our last purchase order). Installation costs are very small, basically labor for about 5 minutes per fill.

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

(a) Year substitute will be available if not currently produced.

(b) Total pounds production per year (current figure).

(c) Years to maximum market penetration.

( d) Maximum total production per year at market saturation.

(e) Estimated percentage of market at market saturation.

(a) The substitute is currently produced

. (b) Not known . Current VLT use of R

- 170 is zero.

(c) We believe that we could achieve maximum market penetration in five years.

(d) Maximum VLT us e of R

- 170 at market saturation. Market size for this applica tion is 25,000 VLT freezer units per year. We believe that

t his technology has the potential to displace 20% of the VLT freezer market after 5 years. That would be 500kg ( about 1,1 00l bs) of R

- 170 per

year.

(e) We estimate that the substitute could displace 20% of the market in five ye ars. About 5,000 units per year.

3. Describe any new equipment and use profiles that will be necessary in or der to use the substitute . If retrofitting of existing equipment is required, detail changes in technologies needed to use the alternative and address any materials compatibility issues. Provi de information on

each end

- use and capital costs associated wi th the substitute or alternative process. Include cost of equipment and/or any new materials, equipment lifetime, changes in labor and energy costs

.

Hydrocarbon refrigerant recovery equipment will be needed for repair and maintenance service groups. The Caresaver Universal refrigerant recovery unit is an example of such equipment and costs abo ut $1,400 FOB. Equipment lifetime is not known.

We anticipate costs of labor and other activities associated with manufacture and repair to be almost equivalent to c urrent practice.
