New Delhi, Apr 5: Joining efforts to fight COVID-19, the Defence Research and Development Organisation (DRDO) has designed a full-body disinfection chamber and a special face protection mask for healthcare professionals, officials said.

The special chamber called 'PSE' has been designed by Vehicle Research Development Establishment (VRDE), Ahmednagar, a DRDO Laboratory.

The walk through enclosure is designed for personnel decontamination, one person at a time. It is a portable system equipped with sanitiser and soap dispenser, officials said.

The decontamination is started using a foot pedal at the entry. On entering the chamber, electrically-operated pump creates a disinfectant mist of hypo sodium chloride for disinfecting, the DRDO said in a statement.

The mist spray is calibrated for an operation of 25 seconds and stops automatically indicating completion of operation. As per procedure, personnel undergoing disinfection will need to keep their eyes closed while inside the chamber, it said.

The system consists of roof mounted and bottom tanks with a total of 700 litres capacity. Approximately 650 personnel can pass through the chamber for disinfection until the refill is required, the DRDO said.

The system has see-through glass panels on side walls for monitoring purpose and is fitted with lights for illumination during night-time operations, it added.

This system can be used for disinfection of personnel at the areas of controlled ingress and egress such as entry and exit to hospitals, malls, office buildings and critical installations, officials said.

Also, Research Centre Imarat (RCI), Hyderabad, and Terminal Ballistics Research Laboratory (TBRL), Chandigarh, have developed face protection mask for healthcare professionals handling COVID-19 patients, the DRDO added.

Its light weight construction makes it convenient for comfortable wear for long duration. This design uses commonly available A4 size Over-Head Projection (OHP) film for face protection, it said.

One thousand face shields are being produced daily in TBRL and provided to Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, it said.

Similarly, 100 are produced at RCI and these have been handed over to Employees' State Insurance Corporation (ESIC), Hyderabad. A demand of 10,000 shields has been received from PGIMER and ESIC hospitals based on successful user trials, the DRDO added.

May 30: A total of 513 domestic flights carrying 39,969 passengers were operated in India on Friday, Civil Aviation Minister Hardeep Singh Puri said on Saturday.

Domestic services resumed in India after a gap of two months due to the coronavirus lockdown. Indian carriers have operated a total of 1,827 flights till Thursday -- 428 on Monday, 445 on Tuesday, 460 on Wednesday and 494 on Thursday.

Puri said on Twitter on Saturday: "Day 5. 29th May till 2359 hrs. Departures 513. 39,969 passengers handled. Arrivals 512. 39,972 passengers handled." A departure is counted as a flight during the day.

During the pre-lockdown period, Indian airports handled around 3,000 daily domestic flights, aviation industry sources said.

In February, when the lockdown was not imposed, around 4.12 lakh passengers travelled daily through domestic flights in India, according to Directorate General of Civil Aviation (DGCA) data.

Airports in West Bengal, Andhra Pradesh, Maharashtra, Telangana and Tamil Nadu have been allowed to handle a restricted number of daily flights as these states do not want a huge influx of flyers amid the rising number of COVID-19 cases.

While domestic services resumed in Andhra Pradesh on Tuesday, they restarted in West Bengal on Thursday.

Though domestic flight operations across the country began on May 25, they could not be restarted in Kolkata and Bagdogra as the West Bengal machinery was involved in relief and restoration work after cyclone Amphan's devastation.

A total of 16 asymptomatic passengers on seven different flights, including 13 who travelled by IndiGo, have tested positive for COVID-19 since the resumption of domestic air services.

Mumbai, Jun 27: The Shiv Sena on Saturday hit out at the BJP over its charge that the Rajiv Gandhi Foundation (RGF) had accepted donations from the Chinese embassy, and asked it whether the issue had any connection with intrusion by the neighbouring country in Ladakh and the martyrdom of 20 Indian soldiers.

The Sena also alleged that those raising questions against the government over the standoff with China were being labelled as Chinese agents by the BJP.

BJP chief J P Nadda had on Thursday targeted the Congress and the Gandhi family saying that the RGF had allegedly accepted donations from the Chinese embassy. Hitting back, the Congress had said that the RGF issue raised by the BJP government was a "manufactured charge" and "diversionary tactic" to deflect attention from the LAC crisis.

"What do you mean by Congress gets money from China? Instead of responding to the issues raised by Sonia Gandhi and Rahul Gandhi over the Chinese incursions, the BJP leaders accused the Congress of receiving funds from China," the Sena said in an editorial in party mouthpiece 'Saamana'.

"Will BJP's revelations about the donations stop the Chinese activities along the border? The BJP should tell what connection does these donations have with the Chinese incursion and the martyrdom of 20 soldiers," it added.

"In our country, many political leaders and parties, and not just the Congress, are beneficiaries of foreign countries. The BJP speaking about this is like throwing stones in the mud," it said.

The Uddhav Thackeray-led party said that Chinese President Xi Jinping visited India twice in the last six years.

"He was hosted in Gujarat. But it is a fact that China has betrayed. Holding talks on the one hand and continuing with the offensive along the border on the other hand is China's old policy," it said.

In the present scenario, the entire country stands firmly with PM Modi. This crisis is not for the BJP or the Congress, but for the entire country, whose prestige is at stake, it said.

"The BJP can fight with the Congress any time later.

But now is the time to fight against China. It should speak on that," the Sena said.
