GAS to be released on London Underground and NY Subways

This world just gets crazier by the day...What is the non-hazardous materials they are going to be releasing to the public? What is the secret? (another secret!)

We all know what happened the last time the BBC showed a planned mock drill on the London Underground.....7/7

Gas to be released on Underground to test fallout

Tests are set to be carried out on the London Underground to see how quickly poisonous gases could spread across the Tube network.

The aim is to create a better understanding of how to respond in the event of them being deliberately or accidentally released.

The trials will be carried out over several days this month using non-hazardous materials.

The gases will be released between the morning and evening peak times.

Transport for London said the gas would be released near the opening of the tunnels and that people should not be able to see, smell or taste it.

Eleven stations will be tested and a further 30-40 stations will be monitored to check how the gas has moved through them.

Nigel Holness, operations director of London Underground (LU), said a similar trial was carried out, at St John's Wood station, in 2007.

He said the tests were being carried out by the Department of Transport.

"We'll be working with the department to take the results, make sure we feed them into our plans to make sure we have the most safe and secure plans for London Underground and London," he added.

Stations where the gases are to be released are:

Oxford Circus
Tottenham Hale
Green Park
King's Cross St. Pancras
London Bridge
Goodge Street
Leicester Square
Piccadilly Circus

NYPD Plans to Release Non-Toxic Gases in the Subway

In an effort to prepare against chemical, biological and radiological attacks in the New York subway, the New York Police Department has announced plans to release harmless gases into the city’s streets and subway stations to better understand the pathways of airborne contaminants. Officials will use more than 200 sensors, set up throughout all five boroughs, to track these benign gases as they disperse. They’ll then use that data to build a computerized model that can help predict how airborne contaminants might behave, depending on locational and weather conditions.

“If some sort of poison or contaminant were dispersed in the atmosphere of New York City, either accidentally or through a terrorist attack … we’d have an idea how it would travel,” says Paul Browne, deputy commissioner of the NYPD. “That would help guide us as to what our responders should do and what instructions we should give the public—for example, do you shelter in place or do you evacuate—and if so, in which direction.”

The so-called Subway-Surface Air Flow Exchange test is being funded by a $3.4 million Department of Homeland Security Transit Security grant and performed in partnership with the U.S. Department of Energy’s Brookhaven National Laboratory. It will take place in July on three non-consecutive days chosen for variance in weather conditions. The public will receive a day’s notice.

The gases, known as perfluorocarbon tracer gases (PFTs), are colorless, odorless, and non-toxic, and they will be released at very low levels. “We’re talking grams of material dispersed over about a half-hour,” says Paul Kalb, division head for environmental research and technology at Brookhaven. “You won’t see anything or detect anything.”

PFTs have been used since the 1980s to learn about airflow in cities, including Washington, Boston, and New York’s Manhattan. Tracer gases are also used to track air pollutants such as coal fire soot, find air leakages in buildings, and even track kidnapping ransom money (PDF).

New York already has several airborne contaminant detection mechanisms in place, although they don’t track the movement of air: Police officers wear radiation detection devices on their belts, and police stations and some subway stations are outfitted with air analysis devices that get checked every 24 hours to see if they’ve collected biological or chemical contaminants, says Browne.

The NYC study will be by far the largest urban airflow study to date, according to Brookhaven. Seven different PFTs will be released at seven locations and then tracked by air samplers set up on street lamp posts and in dozens of stations along 21 subway lines. But don’t expect to learn the results of the study: “That information [about how the air travels], by the way, is not going to be made public,” says Kalb. “The city wants to make sure they’re not helping terrorists do their deed.”

Who pulled the strings?...THE SYMINGTONS..And the Scottish connections...Look no further if you dare
