PHVACR commemorate World Ozone day

Pakistan HVACR Society and Ministry of Climate Change organized a very colourful event in Karachi to commemorate the “World Ozone Day” by the theme of “32 years and Healing”. Dr. Sarosh Lodhi Vice chancellor NED University Karachi graced the event as chief guest. The idea was to discuss the steps taken by Pakistan for the prevention of Ozone layer under the Montreal protocol.

The Event started with the recitation of Holy Quran after which Mr Azim Ashraf President Pakistan HVACR society conducted his welcome address. He thanked the participants of the event for joining him in the war against climate change and briefly discussed how refrigeration technology has been improved to be more Ozone friendly.

The keynote address was delivered by Mr. Zia ul Islam NPM-NOU Ministry of climate change. In his address he outlined the work undertaken by ministry of climate change for the prevention of pollution. He especially mentioned the recent Plastic bag ban and said that very soon it would be implemented nationwide.

Mr Mahmood ul Haq President ASHRAE Pakistan chapter also addressed the gathering. He highlighted the international practices being undertaken for the prevention of Ozone layer. He appreciated the Billion tree project of the government and said that we should focus more on increasing plantation to protect the Ozone layer.

After a wonderful address by the Chief guest Dr. Sarosh Lodhi, presentations were arranged by world renowned experts on Ozone layer and factors affecting it. Mr Mosuf Ali the National expert on Ozone layer started with his presentation and was followed by Dr Waqar Ahmed and Dr. Atif Mustafa and others.

After the concluding address by Mr. Sohail bashir chairman IEP Karachi, the concluding remarks were given by Mr. Farooq Mehboob Vice-President ASHRAE. He explained that Ozone (O3) is a gas found in our upper atmosphere. Each ozone molecule is made up of three oxygen atoms. It is a pale blue gas with a distinctively pungent smell – and it is very scarce. Just 0.000004% of Earth’s total atmosphere is made up of ozone. It is typically said to exist between about 20 and 30km above the Earth’s surface, but it does not have definite edges. The ozone layer protects us from harmful radiation from the sun. In particular, it protects us from UVB, which is a type of ultraviolet radiation. Small amounts of exposure to UVB can result in sunburn, but high levels of exposure would cause us – and most other life on earth – to die.
