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.

associated with the alternative.

APPROXIMATE FORMULATION COST OF RS-50 IS US$7 PER LB.

IN NEW EQUIPMENT, THE BLEND CAN BE USED TO REPLACE R404A, R507 AND R22
IN NEW EQUIPOMENT. IN THE CASE OF R22 NO RE-NGINEERING OF THE EQUIPMENT
IS NECESSARY. IN THE CASE OF R404A AND R507, THE EXPANSION DEVICE WILL
NEED TO BE REDUCED TO REFLECT THE LOWER MASS FLOW RATE, WHICH IS SIMILAR
TO R22. 

EXISTING EQUIPMENT “DROP-IN”, CONVERSION INSTALLATION COSTS ARE MADE
UP OF THE SERVICING COSTS, INVOLVING RECOVERY OF EXISTING R22 AND/OR
R404A/R507 CHARGE AND RECHARGE WITH RS-50 AND CONSEQUENT SYSTEM
OPTIMISATION. TOTAL COST IS THEREFORE COST OF REFRIGERANT CHARGE AND

any new materials, equipment lifetime, changes in labor and energy
costs.

RS-50 IS A LOW GLOBAL WARMING REPLACEMENT FOR R404A AND R507 AND A NON
OZONE DEPLETING REPALCEMENT FOR R22. RS-50 IS SUITABLE FOR USE IN NEW
AND EXISTING EQUIPMENT

RS-52 CAN BE USED WITH NEW EQUIPMENT DESIGNED FOR R404A & R507 OR AS A
RETROFIT DROP-IN REPLACEMENT IN EXISTING R22 & R502 EQUIPMENT.

RS-50 DOES NOT REQUIRE THE REDESIGN OF EQUIPMENT. IN THE CASE OF R404A
AND R507, THE EXPANSION DEVICE WILL NEED TO BE REDUCED DUE TO THE LOWER
MASS FLOW RATE, WHICH IS SIMILAR TO R22

NO SIGNIFICANT CAPITAL COSTS ARE INVOLVED WHEN USING RS-50 AS A
REPLACEMENT IN EITHER NEW OR EXISTING EQUIPMENT.

RS-50 IS COMPATIBLE WITH ALL MATERIALS COMMONLY USED IN SYSTEMS DESIGNED
AND CHARGED WITH R22, R404A AND R507.

INFORMATION ON REFRIGERATION PERFORMANCE AND CAPACITY IS ATTACHED IN
PART IV - LIST OF ATTACHMENTS. IT IS EXPECTED THAT RS-50 WILL SHOW A
HIGHER ENERGY EFFICIENCY THAN R404A AND R507 WHILE HAVING A SIMIILAR
CAPACITY.

NO SITE LOCATIONS AT PRESENT FOR MANUFACTURE OF PRODUCTS USING RS-50.
THIS NEW REFRIGERANT WILL BE USED AT MANY SERVICE SITES. 

NO RELEASE OF CONSTITUENTS DURING FORMULATION AND PACKAGING OF RS-24
EXCEPT AT

DISCONNECTION OF TRANSFER HOSE. THIS IS MINIMISED TO NEGLIGIBLE LEVELS
BY RECOVERY & CAPTURE OF THE REFRIGERANT IN THE DEAD SPACE OF THE
CONNECTION.

GOOD WORKING PRACTICE AND STATUTORY CONTROLS ON EMISSIONS SHOULD ENSURE
EMISSIONS ARE

NEGLIGIBLE. ANY ACCIDIENTIAL RELEASE WOULD BE TO AIR.

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.

THE FORMUATION AND PACKAGING FACILITIES FOR THE PRODUCTION OF RS-50 ARE
DESIGNED AND CONSTRUCTED TO ENSURE NEGLIGIBLE EMISSIONS. THE FACILITIES
COMPLY WITH UK REQUIREMENTS FOR EMISSIONS AND SAFETY AND CONSEQUENTLY
WORKERS ARE NOT EXPOSED TO EITHER RS-50 OR ITS CONSTITUENTS.

PERSONAL PROTECTIVE EQUIPMENT ACCORDING TO THE RS-50 PRODUCT SAFETY DATA
SHEET IS WORN DURING MANUFACTURE OF RS-52, IE EYE PROTECTION AND
IMPERVIOUS GLOVES. ALL EQUIPMENT IS EARTHED.

ALL THE COMPONENTS OF RS-50 ARE LIQUEFIED GASES UNDER PRESSURE

THE AVERAGE NUMBER OF WORKERS EMPLOYED IN THE MANUFACTURE OF RS-50 IS
TWO. THE MAXIMUM NUMBER OF WORKERS IS FOUR.

THE WORKERS OPERATE A ROTATION SYSTEM WORKING A MAXIMUM 8 HOUSRS/DAY AND
APPROXIMATELY 100 DAYS/YEAR.

THE CONTACT PATHWAY WOULD BE INHALATION SHOULD ANY RELEASE OCCUR.

UNDER NORMAL CONDITIONS OF FORMULATION AND PACKAGING, THE ESTIMATED
EXPOSURE CONCENTRATION IS NEGLIGIBLE. THE RECOMMENDED OCCUPATIONAL LEVEL
(TWA) FOR RS-50 IS 1000 PPM AS QUOTED IN THE PRODUCT SAFETY DATA SHEET. 
  





Section D - ENVIRONMENTAL RELEASE AND DISPOSAL IN END-USE



For each end-use of a substitute:    

Provide the estimated amount (in kg/day) of each chemical released
directly to the environment (e.g. as a hazardous waste or 

Waste water 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.

RS-50 IS A REPLACEMENT FOR R22, R404A AND R507 FOR USE IN LEAK-FREE
REFRIGERATION AND AIR CONDITIONING SYSTEMS. RS-50 CAN BE RECOVERED AND
RECYCLED. RESTRICTIONS ON VENTING TO ATMOSPHERE SHOULD BE OBSERVED, AND
RELEASES DURING CHARGING AND MAINTENANCE WILL BE MINIMAL.

ANY ACCIDENTIAL RELEASE WILL BE EITHER INDOOR AIR OR OUTDOOR AIR
DEPENDING ON THE LOCATION OF THE EQUIPMENT AND POSITION OF THE LEAK.

GOOD HOUSEKEEPING AND FREQUENT INSPECTION WILL LIMIT RELEASES.
REFRIGERANT SOLUTIONS LIMITED IN THE UK, RESOURCE SEPARATIONS IN THE USA
AND REFRIGERANT SERVICES INC IN CANADA WILL TAKE BACK RECOVERED RS-50
FOR RECYCLING AND RECLAMATION. IF RS-50 IS MIXED WITH OTHER REFRIGERANTS
THEN THE MIXTURE CAN BE DESTROYED BY HIGH TEMPERATURE INCINERATION IN AN
APPROVED FACILITY CAPABLE OF ABSORBING AND NEUTRALISING THE BY-PRODUCTS.

RS-50 IS NOT A HAZARDOUS WASTE.

FEW MANUFACTURING SITES ARE EXPECTED TO USE RS-50. HOWEVER, MANY
REFRIGERATION  SERVICE SITES ARE EXPECTED TO USE RS-50.

RS-50 CAN BE RECOVERED, RECYCLED AND RECLAIMED USING STANDARD
REFRIGERATION EQUIPMENT IN A SIMILAR MANNER AND AT A SIMILAR COST TO A
SINGLE FLUID REFRIGERANT.

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):

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

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

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

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

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

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

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

RS-50 IS A REFRIGERANT TO REPLACE R22, R404 AND R507 AND WILL BE HANDLED
AND USED IN THE SAME MANNER AS OTHER REFRIGERANTS. GOOD HOUSEKEEPING,
SAFE PRACTICES AND OBSERVATION OF REGULATIONS ON VENTING TO ATMOSPHERE
WILL AVOID END-USERS BEING EXPOSED TO RS-50 AND ITS CONSTITUENTS.

INFORMATION ON PERSONAL PROTECTIVE EQUIPMENT HANDLING AND THE
RECOMMENDED EXPOSURE LEVEL (TWA) OF 1000 PPM IS GIVEN IN THE PRODUCT
SAFETY DATA SHEET. HOWEVER, LOCAL CONCENTRATIONS DURING CHARGING AND
SERVICING OF EQUIPMENT WILL BE CONSIDERABLY BELOW THE TWA.

RS-50 IS HANDLED AS A LIQUEFIED GAS UNDER PRESSURE.

SITE SERVICE WORK INVOLVING RS-50 IS NORMALLY UNDERTAKEN BY INDIVIDUAL
REFRIGERATION AND AIR CONDITIONING ENGINEERS.

THE DURATION FOR HANDLING RS-50 BY WORKERS INVOLVED IN EQUIPMENT
MANUFACTURE OR SERVICE WORK IS LIMITED TO THE RELATIVELY SHORT TIME OF
CHARGING THE NEW REFRIGERANT.

THE CONTACT PATHWAY WOULD BE INHALATION SHOULD ANY RELEASE OCCUR.

UNDER NORMAL CONDITIONS OF END-USE, THE EXPECTED EXPOSURE CONCENTRATION
IS NEGLIGIBLE.



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.

RS-50 IS A REPLACEMENT REFRIGERANT FOR USE IN LEAK-FREE REFRIGERATION
AND AIR CONDITIONING SYSTEMS. HENCE, EXPOSURE TO THE GENERAL CONSUMER IS
EXTREMELY REMOTE. SHOULD EMISSIONS OCCUR, THEY WOULD MOST LIKELY BE THE
RESULT OF EQUIPMENT LEAKAGE, PARTICULARLY AT THE HIGH PRESSURE SIDE OF
THE EQUIPMENT. AS LEAKS TEND TO DEVELOP GRADUALLY AND THE HIGH PRESSURE
SIDE OF LARGER EQUIPMENT IS USUALLY REMOTE FROM GENERAL CONSUMERS AND
THE PUBLIC AND LOCATED IN WELL VENTILATED AREAS, THE LIKELY POPULATION
TO BE EXPOSED IS EXTREMELY SMALL.

THE EXPOSURE MEDIUM WOULD BE AIR.

THE CONTACT PATHWAY WOULD BE INHALATION SHOULD EXPOSURE OCCUR.

THE CONCENTRATION AT THE EXPOSURE POINT IS EXPECTED TO BE EXTREMELY LOW
AND VERY INFREQUENT, IF AT ALL.

	

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.

THE GUIDANCE DOCUMENT STATES: “ YOU DO NOT NEED TO PROVIDE THE
INFORMATION REQUESTED IN THIS SECTION UNLESS YOU CHOOSE TO DO SO.”

(a)&(b) IT IS NOT ANTICIPATED THAT THE GENERAL PUBLIC WOULD COME INTO
DIRECT CONTACT WITH PARTS CONTAINING RS-50. EMISSIONS FROM EQUIPMENT
LEAKAGE, OR EVEN FAILURE, WOULD BE CONFINED TO THE RELATIVELY SMALL AREA
AROUND THE EQUIPMENT. HENCE, EXPOSURE TO THE GENERAL PUBLIC WOULD BE
EXPECTED TO BE NEGLIGIBLE AND VIRTUALLY ZERO.

THE CONTACT PATHWAY WOULD BE INHALATION SHOULD EXPOSURE OCCUR.

THE EXPOSURE MEDIUM WOULD BE AIR.

THE CONCENTRATION AT THE EXPOSURE POINT IS EXPECTED TO BE VIRTUALLY
ZERO.
