Hidden cause for Fierce Covid Spread
Concerns rise about Substandard Ventilation and Air Conditioning in required places.
A Webinar was conducted by the Mechanical Engineering Section of the Institution of Engineers Sri Lanka (IESL) two months ago on the topic “Non adherence of International Standards” pertaining to Air Conditioned Spaces in Sri Lanka.
Places such, as the Department of Registration of Persons, Garment Factories, Barracks, etc., where possibilities of triggering Fierce Covid-19 Spread is high, were discussed.
Air Conditioned Spaces and Naturally Ventilated spaces with high occupancy, not adhering to “Air Change Rates” specified by ASHRAE, ISHRAE (American/Indian Societies of Heating, Refrigeration and Air Conditioning Engineers) or other such professional organizations, that lead to SBS (Sick Building Syndrome) and Respiratory Infections in occupants were discussed.
The Engineering Corps of the Indian Army, citing ISHRAE, warned the Indian Covid-19 Task Force in February, 2020.
All air conditioned garment factories, crowded offices, healthcare facilities, etc., should be checked with instruments to ensure required air change rates meet stipulated standards.
This would ensure that foul air is not kept recirculating without induction of fresh air and expulsion of foul air, resulting in high airborne virus density.
Split type ACs, installed in Sri Lanka, do not have provision to feed fresh air. Owners of Central AC installations shut their fresh air intakes incorporated in them to compensate for poor cooling.
BRANDIX Factory’s AC system should be checked.
If AC and Ventilation Standards are not maintained in enclosed spaces with high occupancy, where airborne virus density is bound to rise, the “3 golden rules” masks, social distancing and hand washing alone would not suffice.

Feeling sad and blue?
Here is what you can do!
Comedy and the ability to have a good laugh are what keep us sane. The good news to announce is that there are many British and American comedy shows posted up and available on the internet.
They will bring a few hours of welcome relief from our present doldrums.
Firstly, and in a class of its own, are the many Benny Hill shows. Benny is a British comedian who comes from a circus family, and was brought up in an atmosphere of circus clowning. Each show is carefully polished and rehearsed to get the comedy across and understood successfully. These clips have the most beautiful stage props and settings with suitable, amusing costumes. This is really good comedy for the mature, older viewer.
Benny Hill has produced shows that are “Master-Class” in quality adult entertainment. All his shows are good.
Then comes the “Not the Nine o’clock news” with Rowan Atkinson and his comedy team producing good entertainment suitable for all.
And then comes the “Two Ronnies” – Ronnie Barker and Ronnie Corbett, with their dry sense of humour and wit. Search and you will find other uplifting shows such as Dave Allen, with his monologues and humour.
All these shows have been broadcast in Britain over the last 50 years and are well worth viewing on the Internet.
Similarly, in The USA of America. There are some really great entertainment shows. And never forget Fats Waller in the film “Stormy Weather,” where he was the pianist in the unforgettable, epic, comedy song “Ain’t Misbehavin”. And then there is “Bewitched” with young and glamorous Samantha Stevens and her mother, Endora who can perform magic. It is amazing entertainment! This show, although from the 1970s was a milestone in US light entertainment, along with many more.
And do not overlook Charlie Chaplin and Laurel and Hardy, and all the Disney films. Donald Duck gives us a great wealth of simple comedy.
The US offers you a mountain of comedy and good humour on Youtube. All these shows await you, just by accessing the Internet! The internet channel, ‘You tube’ itself, comes from America! The Americans reach out to you with good, happy things right into your own living room!
Those few people with the ability to understand English have the key to a great- great storehouse of uplifting humour and entertainment. They are rich indeed!

There is much to learn
After the recent disaster, a great deal of information has been circulating on WhatsApp and YouTube regarding our reservoirs, highways, etc.
In many of these discussions, people have analysed what went wrong and how the damage could have been prevented. My question is this: why do all these knowledgeable voices emerge only after disaster strikes? One simple reason may be that our self-proclaimed, all-knowing governing messiahs refuse to listen to anyone outside their circles. It is never too late to learn, but has any government decision-maker read or listened to these suggestions?
When the whole world is offering help to overcome this tragedy, has the government even considered seeking modern forecasting equipment and the essential resources currently not available to our armed forces, police, and disaster-management centres?

Disasters: Hidden danger
A great deal has been said about Cyclone Ditwah and its impact. To my mind one important aspect of it has not been addressed.
During the 1,400 odd landslides, it washed off a vast volume of soil which entered the various water bodies like tanks, lakes, rivers and streams etc. This process has raised their water levels reducing the water holding capacities (water holding capacity has a different meaning in soil science). What it means is that they cannot hold the same amount of water as before without spilling. Therefore, a precipitation which would not have been significant then can cause spilling of tanks leading to floods now. Hence there is a possibility of experiencing more floods in the future. Due to silting the tanks will carry less water than before, thus reducing the irrigable areas under their command. They will not be able to irrigate the same extents of paddy, thus affecting production.
How do we rectify this situation? It is desilting which can be very expensive.
It is good if these are considered in future planning.
