      Nicol Walker, Project Manager for the National Ozone Unit and Dr. Noel Brown, National Consultant on the HPMP Project speak on the Hydro-chlorofluorocarbons. Ozone is a gas that is present in the ozone layer in the stratosphere of the , it will absorb almost all ultraviolet light which is harmful to many term Ozone depletion can refer to a number of distinct, but related phenomena. Since about the s, there has been a decrease in total volume of the Ozone in the ozone layer, of about 4%, per decade.

    The Ozone Depletion Potential (ODP) was defined in order to classify refrigerants. As they were the worst ones, R11 and R12 are assigned a value of unity, i.e., ODP-R11≡1 and ODP-R12≡1. At present, there are the following synthetic refrigerants containing ozone-depleting substances. Meanwhile, as represented by the enforcement of the REACH regulation* 2 in the European Union, the world is moving toward the goals agreed at the World Summit on Sustainable Development (WSSD) held in , which is to produce and use all chemical substances in a manner that minimizes their impact on human health and the environment by In support of the precautionary approach proposed in.

      Having phased out 95 percent of the ozone-depleting substances covered in the treaty, the Montreal Protocol has not only allowed the ozone hole to begin the healing process, but as scientists have recently discovered, the treaty has also been an incredibly effective measure in .   Ozone-depleting Substances (ODS) Metadata Updated: March 8, This site includes all of the ozone-depleting substances (ODS) recognized by the Montreal Protocol. The data include ozone depletion potentials (ODP), global warming potentials (GWP), and CAS numbers for each ODS. The substances are organized by class.

Regulations to control ozone depleting substances: a guide book It is a reference document written for ODS Officers and legal officers responsible for structuring and drafting regulations and other policies to control and eliminate the consumption and production of ODS.

REGULATIONS TO CONTROL OZONE DEPLETING SUBSTANCES: A GUIDE BOOK Drawing on the experience of 58 developed and developing countries around the globe, this guidebook is designed to support the development of national policy frameworks in developing countries to implement the Montreal Protocol and its Amendments.

EPA has issued a series of regulations to phase out the production and import of Class I and Class II ozone-depleting substances (ODS).The regulations include reporting and recordkeeping requirements for producers, importers, and exporters of Class I and Class II ODS.

Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.

This book describes of international efforts to protect the ozone layer, the greatest success yet achieved in managing human impacts on the global environment. The book provides an account of the ozone.

The production and consumption of most ozone-depleting substances has now been phased out in developed countries, with developing countries not far behind. What happened and why is of tremendous importance for those looking for guidance in the future, particularly those now involved in hugely complicated negotiations on climate by: M/A-COM eliminates ozone depleting substances book layer is less than that of CFC In Septemberthe Montreal Protocol on Substances That Deplete the Ozone Layer (the Protocol) was signed by 25 nations and the Eu-ropean Community.

The Protocol was the first Ozone-Depleting Substances: Alternatives international environmental agreement, and its signing by so many nations. Handbook for the Montreal Protocol on Substances that Deplete the Ozone Layer. Retrieved Augfrom 3 Apparel and Footwear International RSL Management Group (Ed.).

(, January 31). Restricted Substances List (RSL). Environmental Guideline for Ozone Depleting Substances (ODS’s) and Halocarbon Alternatives. 1 Introduction. Background. The stratospheric ozone layer helps filter the sun's harmful ultraviolet (UV) radiation from the earth.

Increased UV radiation harms human health and. MARPOL Annex VI, first adopted inlimits the main air pollutants contained in ships exhaust gas, including sulphur oxides (SO x) and nitrous oxides (NO x), and prohibits deliberate emissions of ozone depleting substances (ODS).

MARPOL Annex VI also regulates shipboard incineration, and the emissions of volatile organic compounds (VOC. Ozone depletion occurs when the natural balance between the production and destruction of ozone in the stratosphere is tipped in favor of destruction. Human activity is the major factor in tipping that natural balance, mostly from releasing artificial chemicals, known as ozone-depleting substances.

Ozone-depleting substances (ODS) contain various combinations of the chemical elements chlorine, fluorine, bromine, carbon, and hydrogen and are often described by the general term halocarbons. These substances are effective ozone-depleters for two reasons.

The first is that they are not reactive (chemically speaking), which means they survive long enough in the atmosphere to drift up into the. Table 7: Detailed list of ozone depleting substances Montreal Protocol Annex Group CFC CFCl 3 CFC CF 2Cl 2 CFC C2F3Cl 3 CFC C2F4Cl 2 CFC C2F5Cl Halons CF 2BrCl Halons CF 3Br Halons C2F4Br 2 CFC CF 3Cl CFC C2FCl 5 CFC C2F2Cl 4 CFC C3FCl 7 CFC C3F2Cl 6 CFC C3F3Cl 5 CFC C3F4Cl 4 CFC C3F5Cl 3.

The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS).These compounds are transported into the stratosphere by turbulent mixing after being emitted from the.

M/A-COM eliminates ozone depleting substances. Topics: Ozone-depleting substances -- Massachusetts., Trichloroethane -- Massachusetts., Hazardous wastes -- Massachusetts. Publisher: Commonwealth of Massachusetts, Executive Office of. EPA regulations designed to protect the ozone layer ozone layerThe region of the stratosphere containing the bulk of atmospheric ozone.

The ozone layer lies approximately kilometers ( miles) above the Earth's surface, in the stratosphere. Depletion of this layer by ozone depleting substances (ODS) will lead to higher UVB levels, which in turn will cause increased skin cancers and.

Terms and purposes. The treaty is structured around several groups of halogenated hydrocarbons that deplete stratospheric ozone. All of the ozone depleting substances controlled by the Montreal Protocol contain either chlorine or bromine (substances containing only fluorine do not harm the ozone layer).

Some ozone-depleting substances (ODSs) are not yet controlled by the Montreal Protocol. Production of most ozone depleting substances has been phased out under the Montreal Protocol. In Australia and other developed countries the phase out of the most potent chemicals.

See ozone depleting substance. (HCFCs). For each ODS, this page provides the compound’s atmospheric lifetime, Ozone Depletion Potential ozone depletion potentialA number that refers to the amount of ozone depletion caused by a substance. The ODP is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of CFC Some ozone depleting substances with a high ozone depleting potential are still used in quarantine and safety applications as no suitable alternative exists.

Methyl bromide is extremely effective as a quarantine fumigant. The immediate fire suppression qualities of halon are needed in confined spaces such as on airplanes and in submarines.

Products that normally contain ozone depleting substances should be replaced with functionally similar products that contain non-ozone depleting substances. Requirements and Policy Statutory Requirements. The Environmental Protection Agency (EPA) established standards regarding the use and disposal of ODS under the authority of Section (a.

The Protocol on the Substances that Deplete the Ozone Layer (MP) was signed in under the auspices of United Nations, said a press release.

The Protocol, which Pakistan signed inhas ultimate objective of elimination of Ozone Depleting Substances (ODS). SincePakistan has successfully implemented various ODS phase out programs.Controlled substances are substances with ozone depleting potential.

The release of these substances to the atmosphere causes significant damage to the ozone layer. Examples of controlled substances being used as refrigerants include, R, R, R, R etc. For a full list of controlled substances please see the full text of EC Regulation.The Montreal Protocol, ratified inwas the first of several comprehensive international agreements enacted to halt the production and use of ozone-depleting chemicals.

As a result of continued international cooperation on this issue, the ozone layer is expected to recover over time.
