| What
causes reduction of ozone layer?
When
carbon chemicals used on the earth escape into the atmosphere
they are broken down by solar radiation to release Chlorine'
Florine and Bromine which in chain reaching destroy the
ozone molecules. This reaction occurs more frequently than
ozone replacement resulting in thinning of the ozone layer.
It is sometimes refereed to a depleting Ozone layer.
IS
THE OZONE LAYER THREATHENED.
Atmospheric
Measurement tells us the Ozone layer is getting thinner
and that at certain times of the year an Ozone layer "hole"
appear over the Antarctica. Some people believe that this
reduction is due to solar or volcanic activity but most
scientist believe certain man made chemicals are major contributors
to the problem. These chemicals include C.F.C FOUND IN refrigerators,
solvents, blowing agent used for foam and halms used in
fire fighting.

INDENTIFICATION
OF ODS
The
National Ozone Unit (NOU) is the central national unit;
usually PART OF THE Environmental Agency or Department of
Natural Resources, responsible for co-ordinating a counter's
efforts with respect to Ozone protection and facilitating
ODs phase-out. The main responsibilities of the NOU include:
· Country Programme
and institutional Strengthening programme implementation
· RMP implementation
often including recovery & recycling programmes and
training programmes for refrigeration technicians and customs
officers.
· Preparation
of proposals for policies, strategies, laws, regulation
incentives, agreements with the private sector and other
measures for national ODs phase-out.
· Consultation
and co-ordination with stakeholders organisation of stakeholder
meetings as necessary.
· Advice and
support to industry, serving sector and end-users on the
different phase-out options for ODs;
· Promoting
of public awareness programs;
· Data reporting,
as required by the Montreal Protocol.
TRAINING CUSTOM OFFICERS
Government
officials in these agencies are well trained on issues pertaining
to the Montreal Protocol, but may have little knowledge
of custom's operations. It is important that the ozone officers
and customs officials meet early on in the implementation
of the phase-out program and regularly thereafter, and each
agency has a clear understanding of its respective role
in implementing import and export controls. Close co-operative
is essential to establish a successful control regime.
Systemic
monitoring of all ports of entry into the country helps
control legal imports and prevent illegal imports of ODs
by identifying mislabeling or other false documentation.
Inspections of imports, belonging to persons known to import
ODs from sale or for their own use, should be mandatory
in order to verify compliance with the regulations. The
environment agency, licensing agency and customs department
should aim for compliance by monitoring imports and exports
of controlled substances through border and document checks.
As
the enforcement officers responsible for monitoring borders
and all points of entry for cargo, customs officers have
the leading role in examining documents and cargo. This
initial examination is the simplest way to identify shipments
of ODs and to distinguish between legal and illegal shipments
of ODs.
Verify
Paperwork.
Paperwork
can be verified with a supervisor and the environmental
protection agency. Customs officers should contact the NOU
or appropriate national office when illegal imports are
suspected.
Verify
Allowances.
Customs
officers should request that importers verify
Possession
of sufficient iciest allowances to import the Quantity of
ozone depleting substances in question and whether the specific
shipment has been authorized through an import permit.
Register
of if the customs officer has no direct online access
to
Allowances
& the register of imports of each import allowances
Permits
and import permits granted or to the actual imports
of
each importer, the customs officer must contract
the
NOU or licensing agency to check the data. The
Importer
must have sufficient allowances granted
And
valid import permits for the specific shipment of
ODS.
Officers
should inspect and analyse the goods if the papers are suspect
or incomplete, ODS is labeled as recycled refrigerant of
if there is any other indication of mislabeling.
Screening for ODS.
Trained
and authorized customs officers may screen for ODS refrigerants
by using refrigerant identifiers, the temperature/ sure
method or leak detectors as described in Chapter7.
Chemical
analysis.
If
chemical analysis in an accredited laboratory is required,
for instance in order to prepare court cases, a specially
trained and authorized technical expert from the government
laboratory should be consulted.
Smaller
refrigerant cylinders can be transported directly to the
laboratory. Mass spectroscope and gas chromatograph are
common methods of analysis.
Licensing
agencies
The
licensing agency may be different from the NOU. Two or three
different agencies may be responsible for licensing ODs.
For example, the Ministry of Trade may license CFCS, WHILE
THE PESTCIDE OR TOXIC Chemicals Board may license Methyl
bromide. The appropriate licensing agency or agencies will
offer or deny licences to importers or exporters of ODs.
Ministry
of trade industry or commerce
The
ministry of Trade, industry or commerce is a key stakeholder
in the implementation of licensing system. This Ministry
often requires a license to I port goods. The license may
be one of many required by the licensing system. Under national
law, the Ministry has certain powers to limit or ban the
import or export of certain goods. This MAY include establishing
a " negative list" of goods not allowed to enter
the country. The collection of data is handled differently
in each country. Please refer to the "country Handbook
on ODS regulations and import/Export licensing system"
for specific procedures. UNEP'S" Handbook on data reporting
" also provides guidance on the collection of data.
Monitoring
& evaluation.
The
ODS licensing agency will monitor the actual use of import/export
licenses and should collect data on the functioning and
performance of the licensing system including the incidence
of infractions, seizures and penalties, the quantities of
imported and seized goods etc. Base on these data, the agency
and the NOU(if different) will evaluate the effectiveness
of the licensing system. In consultation with the relevant
stakeholders, corrective measures may be introduced.
An
effective monitoring system will provide an appropriate
basis for policy decisions, design of regulations planning
of training activities, and public awareness campaigns etc.
INSTITUTIONAL SET-UP &ROLE
OF STAKEHOLDERS
This
section explains the roles of the National Ozone Unit and
the Customs Department in the implementation of the RMP
and the enforcement of national ODs regulations to monitor
and control legal trade and to prevent illegal trade of
ODS,ODS-containing products or ODS- based equipment.
In
general, the NOU co-ordinates the implementation of the
RMP in co-operation with an implementing Agency of the Multilateral
Fund. Often, the NOU is part of an environment agency, trade
and industry agency or meteorological service, but this
is not the case in all countries. The Customs Department
if often part of the Ministry of finance.
Other
import stakeholders involved in the operation and enforcement
of the licensing system may include the licensing agency
(if different from the NOU) police and coast guard, pestcides
Board, Bureau of standard, Government Laboratory, industry
and trade representatives or associations, as well as the
general public.
Each
country has a different division of responsibilities among
its institutions and other players, but all stakeholders
must share the common goal of phasing out ODS. A brief description
of a NOU IS provided below. The "country Handbook on
ODS regulations and import/export Licensing System"
will provided more country- specific information.
7. IDENTIFYING ODS.
The
chapter focuses on the different methods of identifying
and analysis chemical substances, which are potentially,
mislabeled ODs or illegal ODS imports. The different smuggling
schemes and methods to direct illegal trade. This aspect
will be discussed in phase of this custom training. Customs
officers should be trained in the use of ODS- identifying
equipment.
Random
testing/sampling is advised to verify the contents of both
large and small containers of all types of gas and chemicals
as well as ODS equipment and products.
The
following section lists the various ODS-Identifying equipment
available and their limitations to correctly identifying
ODS.
Safety
precaution checklists for ODS testing. |
· Only
specially trained and authorized technicians or personnel
of the accredited Government Laboratory should take
samples for chemical analysis. Local regulations should
be respected.
· Only
trained and authorized customs officers should use
refrigerant identifiers/analysers leak detectors and
perform the pressure temperature test. Local regulations
should be respected.
· The
"halide torch method" (flame test) for leak
testing or open flames should be avoided because some
substances are flammable.
· When
inspecting or testing equipment, the power supply
should disconnected, e.g.. Refrigerators unplugged
or vehicle motors turned off.
· Respect
the safety precautions explained has been as per respect
the local safety regulations.

WHERE CAN
ODS BE FOUND.
ODS can be found in containers and also equipment and products,.
The
container will vary depending on the type of ODS. For example
liquefied compressed gases are contained in pressurized
cylinders.
Liquid
ODS are contained in pressure-less drums, barrels, bottles
or other standard containers as they are used for all types
of liqued chemicals.
ODS may also be contained in the following products and
equipment:
· Vehicle air-conditioning
systems.
· Refrigerators.
· Freezers.
· Dehumidifiers.
· Water coolers.
· Ice Machines.
· Air conditioning
&heat pump units.
· Compressors.
· Aerosol products.
· Portable
fire extinguishers.
· Insulation
boards, Panels and pipe covers.
· Foams, and
· PRE-polymers.
Refrigerant
Identifiers/analysers.
Refrigerant
identifiers/analysers are small portable units and allow
the reliable identification of certain ODS and non-ODS.
The more Sophisticated models detect CFCS, HCFCS, HFCS and
hydrocarbons and are able to also analyse composition, water
content, and purity.
Portable
identifiers/analysers are connected to the cylinder or equipment
and do not require taking samples. Therefore any trained
customs personnel familiar with the use of refrigerant identifiers
/analysers can test the refrigerant charge of cylinders,
refrigerators and stationary and mobile air-conditioning
systems.
Access
valves for equipment containing ODS VARY. Specialized equipment
may be needed to test refrigerators, compressors and mobile
and stationery air-conditioners, as many of these have sealed
metal valves. Access valves for vehicle air-conditioners
are located on the compressor. Safety precautions need to
be observed when testing.
Pressure/
Temperature test.
It
is likely that smugglers will attempt to smuggle pure and
not contaminated refrigerants. The vapour pressures of pure
refrigerants, measured at a certain temperature, are sufficiently
distinct for most refrigerants and provide a good indication
of the refrigerant type.
Exceptions
are CFC -12/HFC-134A and CFC too similar to allow clears
identification of the substances.
In
order to measure the pressure ,a manifold gauge has to be
connected to the cylinder/equipment. The pressure and temperature
should be measured at the same time. If the cylinder/equipment
is stored at a constant temperature, the ambient temperature
will be identical with that of the ODS. The location of
the access valves is described in the above section on refrigerant
identifiers/analyser. Using the pressure/temperature relationships
in ANNEX B8, the type of ODS can be determined.
This
method can be ineffective if nitrogen or other gases are
put into the cylinder/equipment. This will alter the temperature/pressure
relationship.
LEAK
DETECTORS.
Leak
detectors do not indentify or analyse a specific refrigerant.
They indicate the presence of certain atoms (e.g chroline
or fluorine atoms) in the air that would be present only
if the cylinder is leaking.
New
cylinder with virgin refrigerant usually do not leak. Refilled
contained may leak and can be mislabeled.
Storage
areas for refrigerants should be regularly inspected for
leaks for safety reasons.
The
"soap bubble method" is another simple method
to locate leaks.
This
method does not require any testing equipment, other than
liquid soap.

this regards meeting of parties Burkina Faso provide a framework
for significant measures of preventing ODS and exporting
